Title: Reengineering Case Studies and Simulations
Chair: Jose Antonio Dominguez Machuca, University
of Sevilla
SA1D1 Applications of Mass Customization to Small Manufacturing, A. Kimbrough Sherman, Loyola College,
Baltimore, MD 21210, aks@loyola.edu, Harsha
B. Desai, Loyola College, Baltimore, MD 21210, desai@loyola.edu, Kiran Desai, University of Memphis,

Since 1996, Igneous, Inc., a manufacturer of skis for
extreme downhill freeskiers, has sought entry into the market by producing a
"custom crafted" product.
Manufacturing one ski at a time by hand provides little margin and
consumes most of Igneous’ resources. In
this case study we explore the quest for an appropriate technology and
production method by the president of Igneous to improve the fledgling
company’s ability to meet a swiftly rising demand. We discuss the existing and the improved process flows, working
to maintain the "custom" nature of the product. We conclude with recommendations that can be
applied to similar small, niche manufacturers.
SA1D2 Process Re-engineering a Chemical Plant Equipment
Maintenance Activity, Han P. Bao, Old Dominion University, Norfolk, VA

Old Dominion University, Norfolk, VA 23529, ukulk001@odu.edu.
Process Reengineering is an
approach to dramatically improve operating effectiveness through redesign of
critical processes. This paper is about
a case study involving the application of Process ModelTM to a petrochemical
industry equipment maintenance activity.
The main purposes were to create and validate the process model against
real time data, then set up a series of simulation runs to identify solutions
for solving bottlenecks and hidden problems in the process. The modeling
process includes consideration of time-constrained resources and stochastic
maintenance duration times. The
simulation results compare favorably with actual incidences observed at this
facility.
SA1D3 A Process Improvement Methods Study: Splicing Belts, Mary Gander,
Winona State University, Winona, MN 55987, mgander@vax2.winona.msus.edu
This paper describes how a process improvement team of
machine operators at a composites materials manufacturing company learned
process improvement methods in a course provided by their company, and applied
these methods in a successful project involving their splicing belts. A description of the situation prior to
improvements is given along with data gathered by the team. A detailed description of what the team did,
in sequence, and what they discovered, how they arrived at their improvement
strategies, and how these were implemented, along with the results and
supporting data, are given in the paper.
SA1D4 System Configuration and Customer Service Levels in Dial-up Modem
Pools, Paul Schikora, Indiana State University School of Business, Terre
Haute, IN 47809, schikora@indstate.edu.
Growth in the Internet user base has led to an
explosion in demand for the dial-up modem access to Internet Service Providers
(ISP). At times, this growth has left
ISPs with insufficient capacity to meet short-term demand. The traditional response has been to add
capacity, but such a response may not be feasible over finite horizons. This leads to imposing connect-time limits
to more equitably distribute resources among the customer base. This research examines the effect of time
limits and modem pool configurations on two key customer service measures.

Title: Knowledge Management and Learning
Chair: Joyce Hoffman, Stephen F. Austin State
University
SA2D1 Production
as Serial Reconception, Robert Austin,
Harvard Business School, Boston, MA
02163, raustin@hbs.edu, Lee
Devin, Swathmore College/The People’s Light and Theatre Company,
Swarthmore, PA 19081, ldevin1@swarthmore.edu, Jonathan West, Harvard Business School, Boston, MA 02163, jwest@hbs.edu.
We propose a framework for
understanding a category of production processes that are increasingly
important, those in which the product is emergent rather than formally
predefined. By juxtaposing and
exploring similarities between processes for developing open source software,
producing premium wines, and mounting theatrical productions, we derive shared
characteristics which together define a mode of production we call
“reconception.” Reconception can be
contrasted with the “replication” mode that has traditionally been favored in
operations settings, which is typified by mass production. Production structured to facilitate
reconception may be more useful than those structured to facilitate replication
in a variety of contexts.
SA2D2 Learning, Product Integration, and the Dynamics of the Make/Buy
Decision, Geoffrey G. Parker, Tulane University, New Orleans, LA 70118,
geoffrey.parker@tulane.edu, Edward G.
Anderson, The University of Texas at Austin, Austin, TX 78712,
edAnderson@mail.utexas.edu.
Everyone agrees that the decision to make or buy
product components is of paramount importance to firms. However, most normative theory on
outsourcing ignores how learning affects product design over time. By opening the economic black box of the
firm to include the effects of learning on both component production and the integration
of components into a complete product, we develop a model of sourcing that
better explains certain real-world phenomena.
In particular, we show how sourcing decisions that improve a firm’s
short-run performance can have a long-run performance penalty. Additionally, we explain how outsourcing
part of a component run can outperform either complete outsourcing or complete
insourcing.
SA2D3 The Effect of Knowledge Management on the Performance of NPD, Yang Jie,
The Chinese University of Hong Kong, Hong Kong,
China,Yangjie@baf.msmail.cuhk.edu.hk.
Awareness of the importance
of knowledge management (KM) is at a high level. Activities underlying
Knowledge Management in an organization comprise acquisition, innovation,
protection, integration and dissemination. Arguing that KM affects key new
product development (NPD) process by influencing the input and output of
knowledge. Employing factor analysis and regression model, this paper examines
the relationship between KM and NPD performance, and finds some interactions
between KM and moderators also have significant effect on the performance of
NPD. These findings imply that if organizations fail to understand the subtle
ways in which different features of KM influence product development, they may
fail to harvest the full value of organizational learning.
SA2D4 Inward Operational Technology Transfer: An Information Based Typology,
Gregory N. Stock, Hofstra University, Hempstead, NY 11549,
mgbgns@hofstra.edu, Mohan V. Tatikonda,
University of North Carolina, Chapel Hill, NC 27599, mohan-tatikonda@unc.edu.
This paper develops a
conceptual typology of inward operational technology transfer. The typology applies general theories of
organizational information processing and interdependence to the specific
context of inward technology transfer.
We characterize the three dimensions of the typology: technology uncertainty of the technology
that is transferred, organizational interaction between the technology source
and recipient, and transfer effectiveness.
Appropriate matches of technology uncertainty and organizational
interaction result in four archetypal cases called “transfer process types”
which represent effective technology transfer.
We present stylized and real-life examples of effective matches, and the
paper concludes with implications for theory and practice.

SA8A1 The
Role of Operations Managers in the Massive U. S. Trade Imbalance: How Much is
Our Fault? Wickham Skinner, Harvard
University (emeritus), HC61 Box 282B,
St. George, ME, 04557, wskinner@saturn.caps.maine.edu
The U. S has been running an
enormous unfavorable trade balance, with imports of manufactured goods at
unprecedented levels, massively outrunning our ability to export. The result is
a need for an offsetting flow of funds into the U. S., which, gigantic in
scale, has been provided by foreign investments. The situation is precarious,
depending on foreign investor confidence to continue.
Our inability to compete in
many industries is central to the situation. Why can't we do better? How much
of the competitive disadvantage can be laid at the feet of the operations
function? How much are we simply victims of forces beyond our control? This
paper explores these issues at both a macro and micro level.
SA8A2 Managing
Operational Knowledge in Global Networks, Kasra Ferdows, McDonough School of Business, Georgetown University,
Washington, DC, 20057, ferdowsk@msb.edu
What is the best way to
manage operational knowledge, especially when a company has many
factories or other operating units around the world? I suggest (i.e., hypothesize) that the approach should depend on
two key attributes of this knowledge: first, to what extent it is explicit and
second, how fast it is changing. Operational
knowledge is the real know-how of the company—how to do things—and is
different from causal and situational knowledge.
I use published data on
multinational subsidiaries to test the hypothesis. Four generic types of operational knowledge, depending on its
explicability and volatility, are then identified, and it is shown why each
requires a different approach for managing the knowledge. I illustrate these approaches through four case
examples (AOL, Club Med, McDonald’s and Dell). Finally, I suggest four generic
network architectures that would fit each approach.
SA8A3 A Decomposition Approach to
Linking Strategic Objectives with Preliminary Manufacturing Design Decisions,
James W. Duda, 77 Massachusetts
Avenue, Building 35-135, Massachusetts Institute of Technology, Cambridge,
MA 02139, jwduda@mit.edu ; David S. Cochran, 77 Massachusetts
Avenue, Building 35-130, Massachusetts Institute of Technology, Cambridge,
MA 02139, dcochran@mit.edu
In the early stages of
production system design it is critical that designers understand how decisions
regarding system configuration will impact the ability to meet strategic
objectives. A general decomposition of the requirements and design elements of
a manufacturing system is used to link preliminary design decisions with the
firm's strategy. It will be shown how the selection of a manufacturing system
configuration (job shop, FMS, "lean" cell, etc.) can impact the
system's ability to satisfy the general requirements. These general
requirements can then be related to aspects of manufacturing strategy (cost,
quality, flexibility, etc.).
SA8A4 Measuring
Strategy, Challenging Strategy, Andrew Neely, Center for Business Performance, Cranfield School of Management,
Cranfield, MK43 OAL, UK, a.neely@jims.com.ac.uk , Mohammed Al Najjar,
Judge Institute of Management Studies, University of Cambridge, Trumplington
Street, Cambridge, UK.
Organizations the world over
are re-engineering their measurement systems. Often in an attempt to move away
from financially oriented, historically focused measures, to those that better
reflect the value customers receive through the products and services they
experience. Commentators in the field acknowledge that appropriate measures
allow managers not only to monitor the implementation of strategy, but also to
influence it. Even more recently, people have begun to argue that appropriate
measures furnish managers with the data they need to challenge their
strategies. This paper presents data gathered over a three-year period that
demonstrate how managers can use their measurement data to challenge their
organisation's operations strategies, and explores the reasons why more
managers do not do that.

Title: Environment
and Administrative Issues
Chair: Lawrence
Fredendall, Clemson University
SA4F1 Evaluation of the Integration
of the Management of Safety of the Work to the ISO9000/CD2-2000 and BS8800,
in a Company of the Building Site Section, Sub-Section Constructions, in the
City of Rio de Janeiro: A Study of Case, James Hall, Universidade Federal Fluminense, Rua Passo da Patria,
156 Bloco D, Sala 240, Sao Domingos, Niteroi, RJ, Brasil CEP 24.240-210, Quelhas@civil.uff.br, Sérgio R. Leusin,
Universidade Federal Fluminense, Rua Passo da Patria, 156 Bloco D, Sala
240, Sao Domingos, Niteroi, RJ, Brazil CEP
24.240-210
This
work will evaluate the insertion of the management of the safety of the work in
a context integrated with ISO9000 Norm (with its revisional process for
CD2-2000) and BS8800 Guide-Norm in a company, analyzing it and positioning it
in a context of competitive advantage for reduction of accidents and
occupational diseases. It will allow
the direct management in the "construction sites" to become more
preventive and safe. This evaluation
will act since the Anticipation or Planning phase will consolidate during the
productive process.
SA4F2 The introduction
of an Information-based Environmental Management System with Work Groups,
Peter Letmathe,
Clemson University, 107 Sirrine Hall, Clemson, SC 29634-1305, pletmat@clemson.edu. Lawrence Fredendall, Clemson University,
123A Sirrine Hall, Clemson, SC 29634-1305, flawren@clemson.edu.
This paper examines the use of an Environmental
Management System (EMS) to achieve both environmental protection and economic
objectives. This paper explores 3
variables: 1) the advantages/disadvantages of an EMS based on the ISO 14001
standards; 2) the use of work groups to involve employees; and, 3) the use of
an environmental cost accounting system.
Environmental cost systems are an extension of traditional cost
accounting systems to document all environmentally significant flows of
material and energy and measure their costs.
This paper explores the proposition that the use of a formal EMS, an environmental
cost accounting system and the use of work groups for EMS implementation
increases a firm's competitive advantage.
SA4F3 The Impact of the ISO 14001
Environmental Management System on Plant Operations, Gyula Vastag, Department of Marketing and Supply Chain Management
The Eli Broad Graduate School of Management, N 370 NBC
Michigan State University, East Lansing, MI 48824, vastag@msu.edu; Dennis A. Rondinelli, Kenan
Institute of Private Enterprise Kenan-Flagler Business School, Campus Box 3440,
University of North Carolina, Chapel Hill, NC 27599-3440,
dennis_rondinelli@unc.edu
Using
a case study of a manufacturing plant that was among the first in the United
States and the world to certify its environmental management system (EMS) under
ISO 14001 standards, we examine the impacts of the (EMS) and the ISO
certification on plant operations. We use a structured conceptualization
method, involving five managers and ten Pollution Prevention (P2) team members
from the plant, to define and analyze the conceptual domain of the
impacts. The analysis shows that as a result of the certification
process, employees and managers experienced attitudinal changes and the plant
realized operational improvements. The attitudinal changes were related
to increased awareness of environmental matters both among employees and
managers. The operational improvements increased the plant's
effectiveness and efficiency.

Title: Leaving
From Platform Nine and Three-Quarters: Innovations in Experiential Learning
Techniques for Teaching Supply Chain Management
Chair: M. Eric Johnson
SA5G1 The Internet Beer
Game and a New E-Business Simulator, F.
Robert Jacobs, Kelly School of Business, Indiana University, 1309 E.
Tenth St., Bloomington IN 47405.

This presentation describes
an Internet implementation of the Beer Distribution Game. Many teachers
demonstrate the bullwhip effect that is often observed in supply chains by
playing this game with their students. This implementation has the advantage of
considerably reducing the time required to play the game.
In addition, a new Internet based game called the E-Business Simulator will be
demonstrated. This game closely models the action of an Internet business where
sales and purchases are made through e-commerce sites such as e-STEEL or
VerticalNet. The player must make purchasing, production and sales decisions as
part of the simulation.
SA5G2 Learning Exercises using
Siemens Supply Chain Simulator as a Platform, Joyce S. Mehring, College

Lowell, MA 01854, Joyce_Mehring@uml.edu,
978-934-2760.
Siemens Supply Chain
Simulator, a physical model of a complete supply chain, provides a setting for
instructors to teach a variety of supply chain issues. This paper describes our experience with two
exercises that we developed and used with the game: an undergraduate exercise
to introduce students to supply chains and a graduate exercise to study the
coordination of supply chain activities.
SA5G3 The Integration Aspect of
Supply Chain Management: A Framework and a Simulation, Ram Ganeshan, PO Box 8975, School of Business,

The concept of supply chain
management seems to be an essential element in many of today's operations and
logistics management programs. Yet, there is still a lack of integrative
frameworks and teaching tools that specifically tie different supply chain
concepts together. This paper has two specific objectives. First, we describe
an intuitive hierarchical framework that instructors can use as a convenient
"road map” to classify and categorize supply chain concepts. Second, and
also the focal point of this paper, we will describe in detail a tool, the
Supply Chain Simulator (SCS), that helps the student appreciate the scope of
decisions that need to be made, and their impact on managing today's complex
supply chains. The supply chain simulator is based on the hierarchical
approach, and has been successfully used to teach supply chain management to
students at the undergraduate, MBA, and at the executive levels of education.

College, Hanover, NH 03755. 603-646-0526, Fax: 603-646-1308. M.Eric.Johnson@Dartmouth.EDU.
Many
schools of management and engineering are adopting integrated curricula that
prepare students to design and manage complex global webs of material and
information. In a newly released book,
we present the curriculum used by many top engineering and graduate business
schools for courses in supply chain management. In this session we will discuss some of novel learning techniques
described in that book.

SA6H1 Process Reengineering--Closing
Circles with Waste Management, Predrag

Serbia /Yugoslavia.
Abstract: High
operating rates of the refinery processes and associate high R&D costs, are
probably the main reasons why process reengineering of the refinery need to
involve waste treatment. This paper
presents a study on a pilot plant level, considering the possibility of using
pretreated refinery waste as the raw material. That includes slight
improvements in the main refinery process to obtain what we called “controlled”
waste, or “programmable” waste, which could be transformed into a secondary raw
material. Several results were obtained
during the pilot plant experiments.
Spent catalysers were treated with the standard solvent extraction
process for metal extraction, which was followed NaOH treatment for the g-Al2O3 extraction. Obtained raw materials, metals
and g-Al2O3 ceramic, proved to be
economically efficient.
SA6H2 Bicriteria Scheduling Using Genetic
Algorithms, Murat Koksalan, Middle East Technical University, Industrial
Engineering Department, Ankara, 06531
TURKEY, koksalan@ie.metu.edu.tr, Ahmet
Burak Kaeha, Middle East Technical University, abkeha@isye.gatech.edu.
We develop
genetic algorithms for two single machine bicriteria scheduling problems. In both problems we try to generate all
efficient solutions. In the first
problem we consider minimizing total flow time and number of tardy jobs and in
the second problem total flow time and maximum earliness. Both problems are known to be NP-hard. We conduct experiments and compare the
obtained results with those of come lower bounds and previous research. The results are favorable.
SA6H3 Optimal Production-Scheduling with
Equipment Calibration, Cleanup, and Inspection Costs, Funda Sahin, Texas A&M University, Department of
Information & Operations Management, Lowry Mays College and Graduate School
of Business, College Station, Texas 77843, fsahin@cgsb.tamu.edu,
Powell
Robinson, Texas A&M University, probinson@cgsb.tamu.edu.
This paper
considers a production-scheduling problem with equipment setup costs. In addition, a fixed cost, associated with
equipment cleanup and end item inspection, is applied to each day’s
production. Daily output is limited but
can be expanded with overtime. The
objective is to serve all demand while minimizing the sum of setup, overtime
and inventory carrying costs. We
develop an algorithm for solving the problem and apply it to a series of test
problems facing two manufacturers of food products. The test results are promising with a potential 7% cost savings.
SA6H4 Scheduling Parts in a Robotic Cell Served
by a Dual Gripper Robot, Chelliah

J04.7, Richardson, Texas 75083-0688, chelliah@utdallas.edu,
Suresh
P. Sethi, University
of Texas at Dallas, sethi@utdallas.edu.
We consider the problem of scheduling multiple parts in a robotic
cell served by a dual gripper robot.
Both the robot move cycle and the sequence of parts to produce need to
be chosen in order to minimize the cycle time required to produce a given set
of parts which is equivalent to throughput rate maximization. We consider simple robot move cycles that
produce one unit. Choosing such a cycle
reduces the cycle time minimization problem to a unique part sequencing
problem. We investigate the complexity
status of the part sequencing problems and develop efficient solution
procedures to solve them.

In recent years, many POMS textbooks have published
examples of U-shaped manned
manufacturing cells without adequate explanation of how these cells work and
what makes them unique. Manufacturing
cells are designed for flexibility - changes in product design and external
customer demand can be easily accommodated.
The machine tools in the cells are designed with safety, quality,
reliability and internal customer requirements (ergonomics) in mind. Two examples of manufacturing cells will be
presented. The first example will be
the widely published interim cell design which uses machine tools that were
designed for job shops, not for cells but arranged in U-shaped designs and
modified to meet system
design constraints. The fundamental
design equations for daily
demand, machining time, processing time, and cycle time will be explained.

SB1H1 An
Analysis of Preemptive Project Expediting, Robert L. Bregman, University of Houston, College of Business Administration, 4800
Calhoun Rd., Mail Stop 6282, Houston, Texas 77204-6282, rbregman@uh.edu.
With the
fast pace of technological development in today’s economy, it is imperative
that firms effectively manage project timelines to remain competitive. Usually, this is done in a reactive manner. That is, firms react to problems and
expedite as necessary. An alternative
preemptive expediting approach, where the probability of project completion is
maximized by preemptively expediting project activities before problems are
identified, is presented and tested with two experiments in this paper. The first experiment compares performance of
the reactive and preemptive approaches.
The second experiment further examines the merits of the preemptive
approach with various levels of computer-based support.
SB1H2 Real-World Relative
Robustness of Critical Chain Project Management Methods, Adrian Done, UESE- University of Navarra, Avda. Pearson, 21,
08034, Barcelona, Spain, adone@iese.edu; Jaume
Ribera, UESE- University of Navarra, Avda. Pearson, 21, 08034, Barcelona,
Spain, ribera@iese.edu
This study takes a hard look at how the acclaimed
Critical Chain method compares to the more established Critical Path (CPM) and
PERT methods for project management. Currently available software is used to
manage a set of distinct projects, chosen for their spread of complexity and
uncertainty.
Simulation runs subject the projects to varying
conditions that could challenge the actual manager, and ultimate time and cost
performance is determined for each project and management method used. Results
show the relative robustness a project manager can expect from Critical Chain,
CPM and PERT methods when faced with real-world conditions and expectations.
SB1H3 The
Identification of Problems of Network Scheduling in Multiple Projects, Edward D. Walker II, Georgia Southern University, P.O. Box
8152, Management Department, College of Business Administration, Statesboro,
Georgia 30460, edwalker@gasou.edu, James F. Cox III, University
of Georgia, jcox@uga.edu.
In 1997
Goldratt published Critical Chain in
which he applied the principles of theory of constraints to the management of
single projects and revolutionized the way single projects are managed. However, there has been little research
examining the issues of planning and controlling projects in the multiple
project resource constrained environment.
This presentation will seek to identify the network problems of multiple
projects via a hands-on
demonstration; the problems will then be discussed and verified using simple
thought experiments.

SB2D1 Future Research Directions in Project Management, Dwight Smith-Daniels,
Arizona State University, Tempe, AZ 85287, dwight.smith-daniels@asu.edu.
During the past ten years
there has been a renewal of interest in Project Management on the part of
industrial firms, particularly in the high-technology sector. Relatively high failure rates for new
product and process development projects has led to a variety of initiatives
designed to improve the project management capabilities of these
organizations. In this paper we briefly
characterize and review the major research streams in project management
literature during the past ten years, and suggest additions and extensions for
the future.
SB2D2 Case
Studies on the Effectiveness of Shopfloor Improvement Teams, Anton Grutter, University of the Western Cape, Belville 7535, South
Africa, agrutter@uwc.ac.za, Norman
Faull, University of Cape Town, Rondebosch 7701, South Africa, nfaull@gsb2.uct.ac.za.
This paper reports three case
studies of firms that undertook significant efforts to implement teamwork on
their shopfloor. The cases were all from large corporate manufacturers, but
were chosen to represent different process types. Although the initiatives were
all deemed successful, some complicating factors with respect to worker
participation are reported on. Meredith's (1998) suggestion to use case studies
as a basis for theory formulation is followed to generate the hypothesis that
task orientation is associated with effective implementation and stakeholder
orientation is associated with sustainability. A brief analysis of a fourth case
is used to provide preliminary support for the hypothesis.
SB2D3 Worker Discretion in Production Job Design, Robert F. Conti, Bryant
College, Smithfield, RI 02917, rconti@bryant.edu.
Engineers design jobs, not
just machines, and product and process designers need guidelines to achieve
appropriate levels of worker discretion. Researchers agree that workers should
exercise discretion in Continuous Improvement activities but there is
disagreement regarding discretion in production tasks. In “The Machine That
Changed the World”, Womack calls for “stamping out” craft work and worker
discretion. In contrast, Lund, et al, recommend discretionary process changes
by workers as a general principle in “Designed to Work”. The author studied job designs at several
factories to formulate a preliminary discretion model: Jaguar Motors, Waterford
Crystal, Hoshizaki Electric, Toyota Motors, Steuben Glass and Martin Guitars.
SB2D4 A Plant's Technology Approach and Emphasis:
A Contextual View, Kathleen E. McKone, Babson College, Babson Park, MA
02457, kmckone@babson.edu, Roger G. Schroeder, University of Minnesota,
Minneapolis, MN 55455, rschroeder@csom.umn.edu.
While research has identified
potential benefits of specific technology development practices, the literature
has largely failed to identify contextual issues that influence these
practices. This paper explores the
contextual differences of plants to better understand what types of companies
have stronger technology development emphasis and approaches. We propose a theoretical framework for
understanding the relationship between the context in which a plant operates
and the practices that develop the technology base of the plant. We test this framework using data from 163
plants to determine what types of companies are most likely to aggressively
pursue technology development at the plant-level.

SB8D1 Flexibility in Assembly Lines: The Relationships Between Efficiency,
Capacity and Product Mix Flexibility, Aaron Paul Blossom, Bristol Software,
Inc., Rockford, MI 49341, apblossom@bristolsoftware.com, James R. Bradley, Cornell University, Ithaca, NY 14853,
jrb28@cornell.edu.
The assembly line may be made much more flexible with
regard to product mix by adding slack capacity and using a different sequencing
algorithm. We have presented and quantified by simulating with manufacturers’
data a means by which a modest reduction in efficiency of the assembly line can
lead to greater gains in the larger manufacturing system of which the assembly
line is a part. The benefits of making
an assembly line flexible include: reduced order fulfillment time, reduced
dealer inventory costs, reduced transshipment costs between dealers, fewer
obsolete units sold at a discount, and
increased sales.
SB8D2 Scheduling N Products on a Single Facility with Time Varying Demands
and Inventory/Backorder Penalties, Bajis Dodin, University of California
Riverside, Riverside, CA 92521, Mohsen
ElHafsi, University of California Riverside, Riverside, CA 92521.
We consider a single
production facility capable of producing N products each demanded as a varying
rate throughout the planning horizon.
The production facility produces, with a fixed production rate, only one
product at a time. Given the initial
inventory for each product and a finite planning horizon, the problem is to
identify the production schedule with the minimum inventory holding and
backordering costs. Dominance relations
between products and a strong lower bound on the optimal cost rate are derived.
Together, they are used in a branch and bound algorithm to generate the optimal
schedule. The computational results
show that the dominance relations along with the bounding procedure are very
effective in trimming down the branch and bound tree to a very small size,
hence tremendously reducing the CPU time.
SB8D3 Leveraging The Potential Of Process Technology Through Workflow
Scheduling: A Simulation Approach, Paulo J. Gomes, Boston University,
Boston, MA 02215, pgomes@bu.edu.
The paper proposes that
further improvements on the efficiency of process technology can be achieved by
changing the rules and methods through which work is organized. The
implementation of information-based process technology in a bank's check
processing system provides the context for the study. I use a simulation
approach to assess the benefits of introducing alternative workflow scheduling
rules after implementation of the new technology. Results from a hypothetical
setting, using data from an actual check processing center, demonstrate the
cost advantages of introducing a priority-based scheduling rule. The
implications and problems associated with practical implementation are
discussed.

Work-in-process inventory
planning and control has been an on-going problem for the foundry division of a
manufacturer of heavy machinery. The
division, best described as a jobbing facility, produces castings using a
no-bake sand molding process. This research
examined and analyzed the process to positively identify the most critical
areas of in-process inventory and to determine the best approach either through
modern technology or smarter management techniques to aid in improving the
process. Problems and constraints are
identified and recommendations are made for both process and management.

Cgallagher@mail.barry.edu
With little exaggeration, it
can be said that management theory in the twentieth century opened with
Frederick Taylor's ideas and closed with those of W. Edwards Deming. Taylor's Scientific Management was quickly
accepted. Deming, on the other hand,
brought a subtle, more philosophical message.
Only after the Japanese achieved post-World War II manufacturing success
and credited Deming did his ideas gain currency.
This paper compares the
management theories of these two titans, then looks at the limitations of
science in management. As a new century
begins, it may be these limitations which leave the door open to new management
theories.

Ahead by Looking Back: Swift, Even Flow
in the History of Manufacturing, Roger W. Schmenner, Indiana University, Kelley School
of Business, 801 W. Michigan St., Indianapolis, IN 46702, rschmenn@iupui.edu
Manufacturing history is too often neglected in
operations management and its lessons lost.
Its usefulness for testing theory is under-appreciated. This paper uses critical aspects of the
history of manufacturing to provide support for the Theory of Swift, Even Flow
as an explanation of productivity gain.
The rise of Britain in the Industrial Revolution and the rapid
overtaking of Britain by the United States and Germany are argued to be
thoroughly consistent with Swift,
Even Flow, thereby vindicating both theory and the
usefulness of history.

In
the decade of the mid 1980s to the mid 1990s, management gurus and academics
alike were touting the advantages of speed over quality and were suggesting
other initiatives. Early in this period
the Global Manufacturing Research Group gathered data on manufacturing
practices and performance in non-fashion textile and small machine tool
firms. Later, follow-up data were
gathered from some of the same firms.
Data from the two periods are used to determine the extent to which
actual practices changed and what effect that might have had on performance. Personal interviews and case studies
corroborate some of the findings in the survey data.

Maquiladora Operations: Low Cost Production or World Class Suppliers? Vicki
Smith-Daniels, Manufacturing
Institute and Department of Management, Arizona State University, Tempe, AZ
85287-5106, vicki.smith-daniels@asu.edu
Fierce competition forces
companies to rationalize their global production and supply chain
strategies. Foreign direct investment
in maquiladora operations has usually been directed toward low-skilled,
low-value added assembly operations. As
companies are finding that world class production capabilities are more
critical to competitiveness than low costs, maquiladoras are undertaking a
number of different strategies and developing manufacturing competencies beyond
their exclusive low cost charter. Using
data collected from 49 senior managers in Sonoran maquiladoras, this
exploratory study investigates strategic and operational issues.
SB5A2 Distribution Channels as

In today’s hypercompetitive
environment, supply chain design demands a strategic perspective. In particular, competitive pressures such as
globalization, the proliferation of customers’ needs, and the emergence of electronic
markets have forced organizations to reconsider their distribution channel
strategies. Organizations are
increasingly employing multiple strategic options to achieve not only market
coverage, but also to develop multiple strategic options for use in fast-changing
environments. Yet it remains unclear as
to what implications these new distribution channel strategies have for the
firm. We provided an in-depth,
multidisciplinary assessment of how the increasingly strategic role of
distribution channel design has required an extension in the existing
operations strategy paradigm.
SB5A3 Multiple
Criteria Logistics Models to Support Operations Strategy, Siddhartha Syam, College of Business, Marquette University, Milwaukee,
WI, 53201-1881, syam@mail.busadm.mu.edu
Logistics has become the
latest battleground for competition between firms, mainly as a result of
changes in the strategic environment, such as deregulation and the rise of
global supply chains. Facility location models are obsolete in two significant
aspects:
a) They use a single criterion, i.e., cost minimization,
while industry competes on multiple fronts (cost, market share, etc.).
b) Location models determine cost based on commodity
flows, but ignore the significant cost implications of shipment composition and
timing.
The purpose of this paper is
to redress some of the shortcomings noted above and provide an integrated model
for facility location.
SB5A4 Vertical
Integration and Operations Infrastructure, Mike Lewis, Warwick Business School, University of Warwick,

, Paul Walley, Warwick Business School, University of Warwick, Coventry,
CV4 7AL, UK OMPW@rapier.wbs.warwick.ac.uk
There has been a move from
vertically integrated structures, where a large part of the supply system was
owned by one organisation. Theoretical cost and control advantages of vertical
integration were difficult to achieve in practice. Additionally, these systems
lack flexibility. However, modern information technologies, such as enterprise
resource planning systems, are becoming more widely used to integrate supply
chain infrastructure. A key question is whether or not these systems also
create inflexibility and control difficulties. This paper will evaluate a case
example of infrastructural integration to assess the similarities and
differences between the two forms of integration.

For decades, the Beer Game
has taught complex principles of supply chain management in a finished good inventory
supply chain. However, services typically cannot hold inventory and can only
manage backlogs through capacity adjustments. We propose a simulation game
designed to teach service-oriented supply chain management principles and to
test whether managers use them effectively. For example, using a sample of
typical student results, we determine that student managers can effectively use
end-user demand information to reduce backlog and capacity adjustment costs.
The game can also demonstrate the impact of demand variability and reduced
capacity adjustment time and lead times.

Traditionally the
relationship between a company and its suppliers has been a distant one, the
need has arisen to close this gap by integrating their business processes and
thus adding a value-focus over the entire supply chain. Analytical Hierarchy
Process (AHP) and Total Cost of Ownership (TCO) are two frameworks used to cope
with multiple criteria situations involved in supplier selection. This paper
will provide a comparison of the two approaches and will attempt to look at how
AHP can be modeled to take advantage of TCO methodology to make it more robust.

Stephen.Swartz@afit.af.mil
In today's competitive,
global markets, corporate objectives may require the rapid start of operations
in a new location, often far away from the current distribution network. When
the transportation "pipeline" to the new location is constrained by
either cost or capacity, a critical management problem is how to time-flow or
phase the shipment of material into the new location in order to achieve the
greatest value of on-site capability as quickly as possible. The research
presents a structured approach to this problem from a military perspective
(DARPA's Advanced Logistic Project), but with application to civilian
for-profit and not-for-profit organizations.

The importance of
supplier-user interfacing continues to be a major factor in developing and
maintaining a competitive advantage. As this area continues to develop there is
a need on the part of either party (supplier or user) to ascertain the
competitive nature of their relationships. This paper uses an adaptation of the
BCG matrix to examine the positioning of their respective partners. Suggestions
as to strategic alternatives available coming from this position assessment are
proposed

The paper presents a
logistical methodology for modeling the dynamic behavior of food supply chains.
By applying discrete-event simulation the impact of Supply Chain Management scenarios
on chain performance can be assessed. The modeling method is based on the
concepts of business processes, business entities, design variables and
performance indicators. The results of two case studies are discussed where the
modeling method is applied and major performance improvements are identified.
The simulation model is validated by expert testing and field tests in which
simulated scenarios were implemented in real life.

Boston, MA, 02163, kbowen@hbs.edu
For 6 years we have used a
hands on factory simulation to teach operations principles and practices. This intensive exercise requires 6-8 person
teams and 4-6 hours of preparation before each team runs its factory for 20
min. This business objective is to
assemble 40 circuit boards (3 different models), and each team’s performance is
measured (quality, cost and delivery).
The simulation has been used for MBA students (800 at a time) and for
senior executives. For the executives,
the simulation is run for 3 successive cycles where 2 improved factory designs
are tested following coaching and re-design time.

meeting daily needs. The second store,
Aldi, defines its mission as providing staple food items at minimum cost. The students are asked to identify the
competitive priorities of each store and then describe how each store has
conformed its operations to their competitive strategy. I have consistently had very positive

Rarely do we tap the creative
potential of our students when giving a final exam. In the “performance final” student in a second year MBA elective
are tasked with “doing something creative” with material that has been covered
in the course. They select any class
subject and have ten minutes in which to make their creative presentation. The
only requirements are that they must communicate a key insight from the class,
and that they must do it in a way that is engaging. Students have written and performed short plays, develop board
games, composed songs, written and recited poetry, and created and filmed short
video clips. This presentation will
discuss the mechanics and learning objectives of a “performance final.”

Lean manufacturing is an operational approach to
improving the performance of manufacturing systems. The implementation of manufacturing cells is one aspect of lean
manufacturing frequently adopted. The
establishment of cells often requires redesign of equipment to meet the
requirements of the cell and the manufacturing system. However, companies often face difficulty in
obtaining such equipment because of the recentness of lean manufacturing
concepts and due to a lack of structured methods for communicating system
requirements to equipment designers.
This paper reviews some of these requirements and presents a structured
approach that enables companies to design equipment suitable for manufacturing
cells.

In this paper, we present the design and launch of a
new manufacturing plant in Europe. The
plant will produce powertrain products for the European automotive
industry. The production system is
designed according to the objectives of lean manufacturing. The manufacturing system is based on
linked-cell layout. The machining cells
are linked to the assembly cells, which are linked directed to customers. This linked-cell layout provides each
customer with a clearly defined value stream.
The manufacturing systems are designed to be improvable. Production System Design and Depolyment
Framework principles have been applied to the design of the linked-cell
manufacturing system. This framework
has been developed by Professor Cochran and the Production System Design
Laboratory at the Massachusetts Institute of technology.
This paper investigates why machines are presently
designed to reduce unit labor cost by increasing the speed of the machine or by
eliminating direct labor altogether with automation. Machine design practices
are currently shown to be operationally focused rather than system focused.
This paper illustrates the way the unit cost equation and operationally-focused
machine design approaches combine to result in costly factory-system
implementations that do not achieve the enterprise objectives. Examples of the hidden costs that are not
disclosed by the unit cost equation are then identified.

Missouri 65401-0249, ghahrama@umr.edu.
The primary
purpose of this project was to improve services, operations, and scheduling of
a Healthcare Industry (HCI). As part of
this project, the author used various production and scheduling optimization
techniques to reach the project’s objectives.
HCI was founded in 1929 and was established with the concept of “Bring
the home into the hospital.” Innovative
products and dedication to its customers are the primary operation and business
focus. This HCI is a recognized leader
in the worldwide healthcare community.
Short term workforce planning of labor-intensive
transfer lines is addressed in this paper. Although the products (e.g. trucks)
are assembled on a serial line, they show large differences in the processing
times at each station.
These differences are due to the assembling options
provided to the customers. Given the assignment of operations to stations, we
have to find a loading sequence for the products, a worker allocation and a
floater time allocation in order to minimize the whole labour costs at the
line. We develop a solution approach for this problem considering a rolling
planning horizon. Numerical results show that relevant savings can be achieved.

Demand for
medical devices such as pacemakers is growing rapidly with the “technology
push” of new microelectronics and the “demand pull” of an aging
population. Production planning for
these products is increasing in importance as demand increases, competition
intensifies, and product lifecycles shorten.
An uncertain government approval date makes it difficult to create
production plans for phasing-out the existing product and phasing-in the
replacement product. This paper
presents a model for finding the optimal phase-out and phase-in dates. The paper also reports on an implementation
in a Fortune 500 medical device firm.

The importance of communications between sales,
marketing and operations management has been recognized long ago. The theory of
production planning (with focus on capacity management) has been significantly
developed in the last decade. The efficacy of incorporating these
communications as a routine part of production planning is illustrated by a
case study of Ernest Adams Ltd, a leading New Zealand food manufacturer. By
improving the production planning system and interface between sales, marketing
and operations management just for one year the company reduced its workforce
by 20%, overtime use by 50%, and at the
same time increased production volumes.
SC2H5 Using
Quantity Discounts to Coordinate One Manufacturer and Two
In this paper, we develop a
model to examine the effectiveness of using quantity discounts to coordinate
the production and order cycles for a system consisting of one manufacturer and
two heterogeneous buyers. The analysis of the model developed and the numerical
computation indicate that the benefit of coordination decreases with the degree
of heterogeneity of the buyers. The conditions under which it is profitable for
the manufacturer to coordinate with the heterogeneous buyers are demonstrated
through numerical examples.

The contract manufacturing
(CM) industry suffers a unique problem in developing countries: OEMs strategy
to only create and design products, leaves lower value-added manufacturing
tasks to CMs. This promotes a 'commoditization'
of manufacturing services at developing nations. This calls for two types of actions: (1) searching strategies
that involve higher value-added content and, (2) developing, adapting and
applying different tools to improve operational efficiency. In order to contribute to crystallize these
actions, this paper sheds some light on how to integrate different tools which
possess different conceptual approaches.
A case study was developed at an Electronic CM by action research
engagement mode. Specifically, the
paper discusses how QFD and advanced sociotechnical (ST) conceptual tools were
applied simultaneously in order to obtain improvements beyond the manufacturing
sphere - market, logistic and distribution areas.
This paper reports on the Quality
Management practices of ten prominent New Zealand manufacturing companies. Case
study based research examined the Quality Management practices of companies
that had a known commitment to excellent quality. Key findings from the study indicated
that quality management had been recently introduced, and was also relatively
informal, company specific, and ISO 9000 oriented. In addition, some factors that may be considered specific to the
New Zealand environment were found.
These were the small size of New Zealand companies, cultural diversity,
loyal employees and the Do-It-Yourself mentality of many New Zealanders.

The strategic. importance of
the operations function within it firm has been stressed in the operations
management (OM) literature. Furthermore, supply chain management (SCM) has been
receiving increased attention from both researchers and practitioners. SCM
encompasses a wide variety of Interdisciplinary topics, such as supplier
selection, quality management across the supply chain, scheduling, logistics,
information flows, distribution channels, and customer satisfaction. It is
vital to note that the SCM activities should be integrated into a firm's
operations and corporate strategy so that firms can gain competitive advantage and
improve their performance in their respective industries. The purpose of this
study is to establish the strategic components of a SCM model and develop a
framework integrating strategy, SCM, and performance constructs. Future
research will be concerned with deriving testable hypothesis from the framework

attracted an increasing amount of attention on the part of POM experts. This has
resulted in the emergence of the "Supply Chain Management" field.
Ironically, however, much of the attention in this growing field has been on

Method for Aligning a Service-delivery Process with Stakeholder
Management Strategy, Rita DiMascio, School of Business Operations Management, University
of Western Sydney, PO Box 10, Kingswood NSW 2747, Australia, r.dimascio@uws.edu.au
A stakeholder-based performance
measurement system has recently been proposed that links organisational
performance to stakeholder satisfaction, which in turn is linked to process
outcomes. Process outcomes are not, however, linked to process 'inputs' - a
drawback which limits the extent to which a process can be 'engineered' for
maximum organisational performance.
This paper overcomes this drawback in a service delivery process by
making this link and by applying manufacturing improvement tools: Taguchi
methods, flowcharting and simulation. The technique was illustrated on a
patient-treatment process within a public hospital.

for an Integrated Product-Service Matrix:
Developing the Tangible Dimension, Alan Pilkington, Royal Holloway, University of London, Production
and Operations Management, Egham, Surrey TW20 0EX, United Kingdom, a.pilkington@rhbnc.ac.uk
With the current focus of
attention on developing Operations Management theory has come efforts to
formalise the product-process matrix and the proposal of several service-based
equivalents. This paper considers the status of these models and, using an
empirical analysis based on the work of Collier and Meyer, identifies that they
can be linked by a common third axis derived from existing service-product
classifications.

By examining service
operations through the lens of knowledge management (KM), we generate new
insights into information technology’s role in the service delivery
process. Drawing from information theory
and contemporary research on individual and organizational learning, we develop
a model of the knowledge and information transfers among knower, learner, and
the environment. Unlike previous
frameworks, however, this model decouples the learner from the knower and
explicitly incorporates the concepts of environment, medium, and context. Then, by applying this KM-based model to
Wemmerlov’s (1990) taxonomy of service processes, we are better able to
determine when service systems are likely to benefit from technology
application.

Job batching in manufacturing
has been well-researched. While
batching is also employed in mass services, it is not clear to what extent the
manufacturing theory may be transferred.
We studied a single case with multiple instances of batching. Our findings indicate that while the factors
that affect batching in manufacturing still apply, so do additional
factors. The net effect is a broader
set of considerations which influence the determination of when batching is
desired in mass services and how big batches should be.

New services development
(NSD) has become an important competitive necessity in many service
industries. However, NSD remains among the
least understood topics in the service management literature. We introduce the construct of an “NSD
competence” and empirically examine its relationship with NSD performance. We hypothesize that an NSD process focus,
market acuity, service innovation strategy, service culture, and IT experience
determines a service firm’s NSD competence.
This NSD competence, in turn, drives NSD performance. The empirical results indicate a causal
linkage between NSD competence and NSD performance, suggesting that an
integrated management of NSD enhances the likelihood of success.

Title: Concurrent Engineering and
Rapid Prototyping
Chair: Paul Schikora, Indiana State University
There is a lot of active engineering research in the
fields of innovation and technology management. In particular there is wide interest in ways to minimize the
length and the cost of the innovation cycle in industry. Integrating product and process design is
one of these approaches and several alternatives have been proposed to attain
those objectives. For instance, modular
product design methods may be applied to process design as well. Concurrent engineering methods have been tried
in several industries, in particular for the design of flexible manufacturing
systems.

The effective design of
products and services requires greater integration than ever before between
technical feasibility studies, realization, manufacturability, aesthetics,
demand analysis, channel design, and the design of the business model. Observations of student design teams provide
a laboratory setting to generate hypotheses about how this integration works,
mainly by observing the effects when elements are absent. This paper reports on the observation of more
than 25 design teams and the products that they envisioned and prototyped. In each case, the effectiveness of the
prototype, reasonableness of the demand estimates, and appropriateness of the
business model are evaluated.

Prototyping technology (RP) is an example.
The approach applies the Analytic Network Process (ANP) instead of the
more familiar Analytic Hierarchy Process (AHP) to quantify the impact of the
value of reducing development time through investment in TCT. The research has involved collaboration with
eleven companies in a variety of industrial sectors in the United Kingdom and
Austria. The results and sensitivity analysis
of a comparison between conventional and TCT technology are presented for a
number of cases.

Business
schools generally require that students take a course in the functional areas of marketing, finance, and
operations. Unfortunately, students
often enter the core operations course with little knowledge of what the course
involves. Even while taking the class,
students occasionally feel that none of the topics relate to their interests or
professional goals. Our paper surveys
students in the capstone business policy course at the University of Tampa and
assesses their perceived value of the course in an absolute sense and relative
to other courses in the College of Business core.

Factors Influencing Performance in an Introductory Operations Management
Course, Brent Bandy, College of Business Administration, University of

Results of research on factors that influence academic
performance in undergraduate business courses have been reported frequently in
the academic literature. Most studies
have involved introductory courses in accounting, economics, or finance. This study investigates student performance
in an introductory operations management course, and extends the research
beyond the usual ability and aptitude factors into other ability areas,
cognitive aspects, and environmental considerations. Data for the sixty-seven students involved in the study were
derived from their performance in the course, a survey they completed, and
student records. The study was carried
out using simple linear correlation analysis and stepwise multiple regression
analysis.

We
investigate the impact of student’s perceptions and prior knowledge of OM on
the resulting learning in the core course.
We have a two-stage survey study.
The first survey is administered on the first day of class and the
second survey on the last. The survey
is administered in multiple classes, class sizes ranging from 50 to 350
students. Multivariate analysis
techniques are initially used to refine and validate the survey
instrument. Subsequently, Structural
Equation Modeling is used to test the model developed to describe the
relationships among the students’ perceptions and prior knowledge of OM, the
population characteristics, and the amount of learning that takes place in the
core OM course. This study is the first
of a series that will be repeated in multiple semesters.

Teaching Operations Management to Historically Disadvantaged Students
in South Africa, Anton Grutter,
University of the Western Cape, Priv Bag X17, Bellville, 7535, South Africa,
agrutter@uwc.ac.za
The
University of the Western Cape is categorized as an"historically
disadvantaged university" and draws it students from communities where the
education systems have all but collapsed. Creating learning experiences for
these students is a general challenge, but developing an understanding of the
effective management of operational resources when student's often only have
experience of extreme resource scarcity presents particular challenges. This paper presents the model, a simplified
version of Hill's 1995 model of manufacturing strategy, used to introduce
students to operations management. It also reports on the introduction of mind
maps to strengthen the cognitive skills development of the students and the
case study assignment which enables students to apply the model in a real world
situation.

This paper examines learning curves in healthcare. In
contrast to previous research, we argue that learning curves may vary across
organizations engaged in the same learning task. We investigate this issue in cardiac surgery departments
implementing a new technology for less invasive cardiac surgery. We report on
analysis of detailed data on procedure times from a sample of 662 patients who
underwent this operation at 16 different institutions. This unique data set
allows us to estimate learning curves across organizational settings. We find evidence that the slope of the
learning curve varies significantly across organizations. Theoretical and practical implications of
the findings are discussed.

Research show that service
quality often deteriorates as capacity utilization increases. This paper reports the results of a longitudinal
research project conducted over a period of four years, investigating the
effect of varying levels of demand within mass customer service organizations,
upon the customers’ perception of the many aspects of the service quality they
received. The initial results combined
with customer importance priority rankings, were intended for incorporation in
capacity/demand and facilities planning, and resource allocation for service
improvement. The later results enable
an assessment of the effects of operational changes on service quality and the
methodology’s robustness over time.

Facing the challenges of
express courier services and Internet communications, postal service providers all
over the world need radical improvements in the delivery performances. Variability in mail volumes across different
regions and seasons, changing mail characteristics, and restrictive workforce
policies make the task very complicated.
Automation technologies for address recognition, sorting, and delivery
point sequencing have been introduced to improve the service productivity, the
result of which vary widely depending on the management policy. In this paper we examine the delivery
productivity issues in Korea, Japan, USA, and Germany, and then explain how
different management approaches result in different performances.
Quality
in healthcare is reflected by outcome measures of a series of clinical
results. Proposed measures suggested by the JCAHO are
discussed together with the techniques used in analyzing quality. Some examples of real world results in
cardio-thoracic surgery, Bowel surgery, and Orthopedic surgery are
presented.
SD1B5 Identifying a Common Set of Weights Appealing to
All DMUs in Data Envelopment Analysis, Daniel L. Tracy, Washington State University,
Pullman, WA 99164-4736, dtracy@mail.wsu.edu
Data Envelopment Analysis
(DEA) is a mathematical programming approach to measuring the efficiency of a
Decision Making Unit (DMU) relative to a group of DMUs. When they have multiple inputs and/or
outputs, weights must be assigned to each input/output. Each DMU may choose different weights to put
themselves in the best light. However,
in practice, most managers evaluate DMUs based on deterministic criteria. Even when considering a fairly homogenous
group of DMUs, specialization may occur resulting in disagreements regarding
the weight structure. A model with an
application is offered to identify a common set of weights agreeable to all DMUs.

A cooperative supply chain is
an arrangement whereby its members achieve coordination through negotiations
and compromise, in honoring commitments made to each other. Such an arrangement
offers opportunities to design, model, and analyze problems with local
perspective of a Member and global view of a Group. It also holds the potential
of emergence of divergent supply chain network topologies, in order to satisfy
dynamic market conditions. These unique configurations and associated problems
require formulations in relation to a framework, recognizing their domain
dependence within the domain independent environment of the supply chain. In
this paper, we present a framework that enables configuration management of a
cooperative supply chain based on the principles of collaborative engineering of
its functional domains.

Supply chain management has
gained currency as the final frontier of business. The risks associated with
supply chain management from a buyer's perspective include the quality of a
supplier's goods, supplier's long-term solvency, supplier's ability to manage
downward pressure on its prices, supplier's ability to use the latest in
appropriate technology, and the supplier's ability to deliver on time. On the
other hand, portfolio management in finance affords us an opportunity to
examine the risks of various investment alternatives. We explore the
application of portfolio theory to the evaluation of the risks in supply chain
management using several real life examples.

Many practical distribution
and storage problems can be modeled as transportation problems with
exclusionary side constraints. In such problems, as in traditional
transportation problems, goods at a set of source locations need to be shipped to,
and stored in, a set of warehouses at possible minimum total shipping and
handling cost. In addition, a warehouse may not be allowed to receive goods
simultaneously from some sources because goods incompatibility may cause damage
or deterioration to the goods and/or to the facility. Mathematical formulations
of the problem are discussed. Currently available heuristic solution procedures
and exact solution algorithms are examined

The term, supply chain
management has been used to describe the integration-of distribution activities
by wholesalers and retailers, as well as manufacturer attempts to integrate
supply activities. Today, no universally accepted definition exists for supply

Internet-based Communication on Supply Chain Management, David
McCutcheon, University of Victoria, Faculty of Business, dmccutch@business.uvic.ca
There has been some debate
about the probable impact of Internet-based systems on buyer-supplier
relationships. Steinfield, Kraut and Plummer (1997) reviewed findings of
previous studies and concluded that, overall, "extranet" systems
would lead to strengthening of existing buyer-supplier relationships and
reductions in the typical supplier base. Most of these studies were at a
macroeconomic level. More relevant for most firms is the Internet's likely
impact at the industry or business unit level. Here, I discuss some factors
that may influence how Internet-based technologies could affect "make or

Up to now, Knowledge
Management (KM) was either related to IT-based explanations or metaphysical

Management. We like to show alternative
ways to solve the problem of Knowledge-distribution within organizations. To do
this, we use computer based simulation models that are not merely mathematical

In recent years, product
modularization has received increasing interest among both practitioners and
academics. A literature survey resulted in four different methods for
modularization. The aim of this paper is to analyze these methods applicability
for four basic product architectures. The results show that the modularization
methods are useful for products with simple product architecture, i.e. one
function is allocated to one physical module. However, concerning more complex
architectures in which several functions are allocated to several physical
modules, the methods seem insufficient. Therefore, to make the methods suitable
for complex products, areas for further development are suggested and
discussed.

Previous conceptual models for assessing product and
service quality have become important instruments in understanding consumer
behavior and the perceived quality of an organization’s market offerings. However, many organizations’ offerings don’t
fit the traditional definition of a manufactured good or a service. Organizations now focus on building
long-term relationships and the experiential elements of their market
offerings. In addition, recent advances
in multiple technologies provide an unprecedented opportunity to redefine
long-established market niches. This
paper proposes an integrated model of product quality to accommodate the
expanding definition of a market offering and to reflect the affect of advances
in technology.

The growing emphasis on
affordability for space transportation systems requires the assessment of new
space vehicles for all life cycle activities, from design and development,
through manufacturing and operations. This paper addresses the operational
analysis of launch vehicles, focusing on modeling the ground support
requirements of vehicle architecture, and estimating the operational costs and
flight rate. This paper proposes the use of Activity Based Costing (ABC)
modeling for this analysis. The model uses expert knowledge to determine the
activities, the activity times, and the activity costs based on vehicle design
characteristics. The approach provides several advantages to current approaches
to vehicle architecture assessment including easier validation and allowing
vehicle designers to understand the cost and cycle time drivers.

as a project. Precedence requirements on the order in which topics are covered,
as well as the inclusion of constraints on both classroom and faculty
availability are considered in the model.
There will be ample opportunity for questions and comments.

Integrated, enterprise-wide
systems have become the de facto standard
for transaction processing in organizations.
At Arizona State, we are challenged by choices about the best pedagogy
to use in preparing our students to deal knowledgeably with rapidly changing
technology. We have experienced success
using ERP systems in our accounting and information systems curriculum at
undergraduate and MBA levels. Now we
are introducing ERP and e-business concepts throughout our business curriculum.
We will share our successes and failures as we present an overview of ERP
systems, their relationship to supply chain management, and other e-business

Benchmarking for the SME Sector-
A
Method of Targeting POM Improvement, John
F Dalrymple, Computing Devices Professor of Quality Management Centre for
Management Quality Research at RMIT, PO Box 71, Bundoora 3083 Victoria
Australia
This
paper explores some of the issues surrounding quality in SME’s and presents results
of a study of an international business profile benchmarking tool. This
instrument has the potential to identify the relative strengths and weaknesses
of small and medium sized companies by comparison with their international
counterparts of a similar size, turnover, number of employees and industry
sector. Information provided by this instrument may enable areas to be targeted
for improvement in the SME’s production operations management. The ability to
benchmark across the business profile against international competitors
presents possibly the first such opportunity as global purchasing is adopted.

The
objective of this work is to analyze the quality management models used by
companies in the metropolitan area of Rio de Janeiro in order to evaluate the
relation between these models and the growing results in its business. In a
context where the competition increases more and more, the understanding that
an increment in revenues and reduction in operation costs, can both be achieved
through a better efficiency, productivity and the adequate use of capital
investment leading to the competitive advantage.

As the innovation and change process are important for to
get and maintain a competitive advantage, this paper present that the enterprise
must be oriented for process which guide your actions for the knowledge of the
enterprise competitive dimensions, your position inside the supply chain and,
consequently, to develop a technological strategy. In this context, the Total
Quality Management, which is a global

Currently, performance measurement is seen as an
effective tool for translating strategy into action (Kaplan & Norton,
1996). To date, most performance measurement system design processes have
adopted an external, or market based, approach in the tradition of Porter
(1980). As a result, the internal, or competence approach, has been widely
ignored. An effective performance
measurement system is designed to focus effort and resource. It is therefore
important to develop key measures for learning and the development of
competences. This paper will develop a
competence driven framework for performance measurement and illustrate this
using case study examples.

Louisville, KY 40292, weny@louisville.edu
Since safety stock is used to
cope with demand forecast error, mangers of risk-seeking, risk-averse, or
neutral type is likely to determine safety stock differently that resulted in
different master production schedule, various ending inventory levels, and
inventory related costs. Since
different management accounting alternatives treat inventory differently, the
decision of safety stock will then affect manufacturing performance. This study
uses simulation modeling to examine the interactions of various safety stock
levels, management accounting alternatives, product mix algorithm, and product
complexity on various manufacturing performance over a 3 year planning horizon.
The results of this study will help managers of various types to identify an
appropriate safety stock level and management accounting alternative under
manufacturing settings.

A
simulation model of an existing high-speed liquid filling production line was
developed, using ARENA HiSpeedSim software.
The production line includes eight different processing stations, more
than 200 feet of accumulating-type conveyors and thirty photo-eyes that
electronically control the production process.
The line is capable of producing 200 bottles of liquid per minute, 24
hours per day seven days per week. The
simulation model developed may be used to identify bottleneck stations as well
as the optimal line settings, including conveyor lengths and speeds as well as
photo-eye locations in order to maximize throughput. Initial experimentation with the model has provided alternative
settings that would increase throughput more than eleven percent over the
current throughput.

This paper
describes the design, development, and implementation of an Internet version of
MRP-DSS, a Manufacturing Resource Planning Decision Support System (http://mrpdss.wide-link.com/). It will describe the unfolding experience of
MRP-DSS starting from an MSDOS BASIC version in 1984 to a DBASE Clipper version
in 1992, and now to an Internet version in 1999. It will focus its description on enhancements in capability and
benefit to the user as a result of rapidly evolving new system technologies and
platforms. MRP-DSS has many experienced
users in both business and educational applications. The paper will discuss issues and challenges from the users’
perspectives of the evolving advantage, versatility and future potential of
Internet, as MRP evolves into ERP and Supply Chain Management
applications. Sample screen displays of
Internet MRP-DSS will be used to demonstrate its design features, user

Abstract: Perhaps
the most famous performance measurement and strategy articulation methodology
is Kaplan and Norton’s Balanced Scorecard.
Since its inception in the early 1990s the Balanced Scorecard framework
has evolved considerably. Further,
academics and consultants have developed increasingly sophisticated models of
design and implementation, such that today, the scorecard process and outcome
is far removed from its archetype. This
paper will review and critically appraise this evolution, drawing on the
considerable academic literature on the scorecard, as well as several case
studies of scorecard design and implementation. The paper reveals several flaws in the most common approaches to
scorecard design.

With
the increasing use of supply chain management practices, more and more
companies are focusing on just-in-time purchasing (JITP) techniques to
coordinate and integrate their inventory management activities. On the other hand, the literature suggests
that the firms producing logistically complex products may experience
difficulties in implementing JITP. This
study empirically investigates the relationship between the logistical
complexity and the extent of JITP implementation. Data for this research were collected through a cross-sectional
mail survey from firms operating in the US.
The findings and implications for future research are discussed.

Competitors driven by
increasing customer demands for new and differentiated products and by
pressures to enhance quality and reduce cost are finding that improvements in
purchasing practices become indispensable. This research reports on an
empirical study which uses a sample of 150 firms in four industries and relates
key purchasing practices to competitive capabilities Purchasing practices
include supplier selection, supplier development, and purchasing involvement in
product development. The methods involve an exploratory factor analysis and
reliability analysis where the measurement model is examined. This is followed
by the testing of a structural model that relates purchasing practices to
competitive capabilities.

Based on the current trend, a
significant amount of a manufacturer's profitability depends on its ability to
plan for a secure and effective distribution system in two directions, goods to
and from the customer/retailer. A major premise supporting this statement is
the dynamic change occurring in retailing. As American retailers have
liberalized return policies, under the auspices of customer service, both
manufacturers and retailers are confronting a plethora of returned merchandise.
This paper describes and addresses this problem and proposes some solutions to
American manufacturers and retailers.

Layout Design System, Wen-Chyuan Chiang,
University of Tulsa, Tulsa, OK 74104, wen-chiang@utulsa.edu, Panagiotis
Kouvelis, Washington University, St. Louis, MO 63130.
This paper presents an integrated
visual facility layout design system to solve facility layout design problems
with geometric constraints. The system employs a tabu search algorithm as the
search engine with heuristic neighborhood control and manual interference
mechanism to obtain good solutions. The software implementation will be
demonstrated.
This paper is aimed at studying focused cellular
manufacturing. We define focused cellular manufacturing as a layout scheme that
groups components by end-items and forms cells of machines to fabricate and
assemble end-items. It is not
classified as a cellular manufacturing layout since it does not attempt to take
advantage of process similarities. It
also is not classified as a flow shop since there are no machines dedicated to
individual operations and the machines are not arranged in a series. The results indicate that the focused
cellular manufacturing scheme has a batching advantage (i.e., it has to wait
less time to batch components before assemble). This advantage dominated the balanced machine utilization benefit
of the job shop layout scheme. The job
shop was only able to overcome the batching advantage when there were small
batch sizes or large set-up time magnitudes.

Hayes and Wheelwright
(1919) provided the product-process matrix to emphasize the importance of the
cooperation of manufacturing (processes) and marketing (products) to achieve
unified goals based on Skinner’s tradeoff theory. But recently some authors (Ferdows and De Meyer, 1990; Noble
1995) have empirically verified that firm can achieve multiple competitive
performances simultaneously. Especially
high flexible process capability greatly enlarges the feasible zones and
reduced constrained zones in the product-process matrix. Therefore, product-process matrix needs some
modifications. This paper discussed and
empirically tested the impact of flexible process capability on product-process
matrix, and provided further evidence of the compatibilities of multiple
competitive performances rather than tradeoffs.

Introduces
a non-traditional approach to the teaching and practice of queues for analysis,

the concepts and methods of statistical process control are incorporated into
the modeling process of a queue as well as the actual application of such

State University, Las Cruces, New Mexico, dwieters@nmsu.edu
This paper proposes an
experiential approach to learning manufacturing planning and control procedures
and concepts. Students cast in various organizational roles develop and use a
spreadsheet model in a hypothetical firm to detect and respond to operating
issues in purchasing, warehousing, logistics, quality, engineering changes, and
marketing practices. An In-basket methodology guides students through a
sequence the issues and experiences supported by a Material and Capacity
Resource Planning spreadsheet. Data definition skills, spreadsheet skills, and
problem driven learning are the goals. A senior level undergraduate course in
production planning and control is the setting.
SE5G3 Teaching
Rolling Horizon Production Planning Via Case Studies, Henry S.
Maddux, Department of Management and Marketing, Sam Houston State University,
Huntsville, TX 77341-2056, mgt hsm@shsu.edu.
The process of implementing a rolling horizon
production plan is often confusing to students. The process of updating inventory and workforce conditions as well
as forecasts while tracking cost performance becomes understandable when one
actually applied the process in practice or through a simulation. This session will present an actual case set
in the wood processing industry. The
planning problem is complicated by high seasonality of demand and limited
ability to carry inventory. A linear
programming approach to the problem will be presented. The step-by-step procedure of teaching model
formulation, solution, updating, and cost tracking will be outlined. The nature of cycling through future
planning periods will be demonstrated using actual class experiences.
SE5G4 Communicating
Operations Management: Exercised to
Explain Models, Concepts and Outputs to Non-POM Professionals, Harry M. Rosen, Professor and Chair, Department of Management,
Zicklin School of Business, Baruch College, C.U.N.Y.
Our students may master
sophisticated quantitative models, yet have difficulty explaining their results
without resorting to jargon. And the
challenge of communicating results of analyses to intelligent, but uninformed
audiences, is generic to many aspects of business.
Therefore, three cases were
added to core OM courses, requiring students to:
1-Describe a complicated
quantitative model.
2-Describe the output of quantitative
analysis.
3-Describe, from beginning
to end, a model, its application, the output, and recommendations.
These cases will be
presented, along with a discussion of student response. Our unique approach to distinguishing
problems of style, from problems of substance, will also be described.

A.B. Freeman School of Business,
Tulane University, amiya.chakravarty@tulane.edu
Digital
connectivity, far from being just a passive technology enabler of fast and
reliable data transfer, has major strategic implications for the entire value
chain. These come from being able to
integrate the adaptability of a modular supply chain with process alignment in
an integral supply chain. It can also redefine values (in a value chain) by
rapidly adding or deleting entities, and by leveraging economic externalities
through connectivity. The three major
dimensions of electronic connectivity in a supply chain thus are ownership,
process alignment, and adaptability.
In this tutorial we examine the issues
surrounding the creation and operation of digital supply networks. These
include, new business models using the Internet, extended and virtual
enterprises, value-chain reengineering, digital process alignment for
collaboration; aggregator, assembler, and alliance models of E-marketplace;
agility in a digital enterprise, channel assembly, transaction speed, inventory
routing, cash-to-cash cycle, supplier capabilities, supply contracts, and online
auctioning (products, components, and capacity).

In recent years, the Internet has become increasingly
important within the higher education system. So far it has served as a popular
delivery tool for distance education and has supported conventional
education. However, the Internet is
changing the world in so many ways that there is no doubt it will play an
increasingly important, expanded role in education. It is likely that the extent of its impact will resemble the
dramatic changes that E-commerce and E-business have brought in the way the

industry. In academics, the access to
pervasive information has dramatically modified how students complete their out
of class work. However, this revolution
is barely making inroads into the classroom, with some professors feeling that
using PowerPoint presentations as the height of computer-based teaching. The question then becomes: will POMers in
academia be up to the challenge of the task of drastic transformation required
for the new Internet world or will we again take a back seat as our industrial

Recent
studies of today's university students reveal that as a group they are
goal-oriented, confident, willing to work, and technologically savvy. But they
also come to the university with fewer skills, a habit of success (not
necessarily earned), and inexperienced in the process of thought and reasoning.
The dissonance between student and faculty expectations coupled with increased
class sizes and fewer faculty resources have created a frustrating learning
environment at best. This workshop
presents the author's experiences using active learning techniques and
technology to "reach the student" in the intro POM course and build a
foundation for continued learning.

Studies show that straight
lecture does not always motivate students to learn and integrate topics. This presentation describes how Factory
Software (James E. Ward, Associate Professor, Purdue University) was used to
enhance student interest in course topics and improve the analysis and
synthesis skills of operations management students. Initially, the Factory software was used to demonstrate the
real-time effect of planned releases to the net requirements. However, the impact was a more meaningful
association of related topics, such as job scheduling, lot sizing, and work
center loads. The software package not
only enhanced the knowledge base of the student but also improved the student’s
abilities to analyze and synthesize course topics.

Since Eliyahu Goldratt
popularized the theory of constraints in his books, The Goal, and Its Not Luck,
POM courses have expanded coverage of concepts such as Throughput, Cycle Time,
and WIP. This paper describes a
hands-on educational exercise and case study in which students are challenged
to improve TP and CT for a manufacturing process using ProModel software. Students must allocate a fixed budget over a
4-month period. Process changes (reducing mean and variation in processing
times, adding capacity, etc.) have a specified cost. Students modify the ProModel simulation model and prepare a
report which shows their systematic changes and corresponding results.

Teaching finance-only-interested Business students
manufacturing planning & control is no easy task. Very dynamic in nature,
MPC systems training using static methods (overhead projections, discursive
sessions) is both ineffective and boring for nowadays students, brought up in
the MTV & Internet era of quick cuts. Competitive business games seem to be
much more appropriate and participative, allowing students to learn by doing.
Based on the old ITEC simulation game, a brilliant teaching tool developed by
Prof. Bill Berry & team at the University of North Carolina more than 10 years
ago, an Excel-based graphic interface was developed and a new way of utilizing
ITEC was created to result in a highly effective method to teach both
Operations Strategy and Manufacturing Planning & Control. These novelties
are described and 5 years of experience successfully teaching more than 100

with considerable control over the production process including such options as
order splitting, expediting, order pre-empting, and prioritizing.

TA1D1 Managing Complex Organizations: Toyota Production System Rules-in-Use,
Steven Spear, Harvard Business
School, Boston, MA 02163, sspear@hbs.edu.
The Toyota Production System has been linked to
Toyota’s outstanding performance (low cost, high quality, short lead times, and
flexibility). This paper looks beyond
the familiar TPS tools to search for the underlying principles for how this
management system works. Field
investigations of 176 days at 33 sites in Japan and North America lead to a
recognition of distinct patterns that appear as “Rules” for designing,
operating, and improving work-activities, connections between activities, and
pathways constructed from connected activities are fundamental. These Rules and their logic will be
detailed.
TA1D2 Modularity in Organizational Design, Steven Spear, Harvard Business
School, Boston, MA 02163, sspear@hbs.edu.
Organizations managed according to the “Rules-in-Use” that
are the essence of the Toyota Production System are nested modular. This structure, sometimes used for managing
product design projects, is particularly effective for managing collaborative
work in production settings. It allows
responsibility to be assigned so that individual work can be done in an
outstanding fashion, so that the pieces can be integrated into a coherent,

Sustainable manufacturing
improvement is becoming a prerequisite for long-term competitive success. The
key is developing a long-term improvement path, rather than gleaning quick hits
from different fads. Yet, sustainable manufacturing improvement is not an easy
task. The paper focuses in issues in sustaining manufacturing improvement.
Based on fifteen case studies of UK manufacturing companies, the paper
illustrates the obstacles companies experienced in sustaining manufacturing
improvement over time. These are focusing on the "flavor of the month",
achieving only islands of excellence, and experiencing initiative overload.
Mechanisms used to overcome the obstacles are the second part of the paper.

Manufacturing strategy is
about linking manufacturing decisions and activities with corporate strategy.
Korea has developed a strong manufacturing base in several different
industries. But little is known about the manufacturing strategy of Korean
firms. We develop a model examining the manufacturing strategy, leadership,
improvement, and their performances. Classification of different manufacturing
strategy and their performances are established from a sample of 200 Korean
companies using the framework.. We explain the current characteristics of
Korean manufacturing companies and the challenges for them to be more
competitive in the future.

There has been a strong
movement going on in Japan, which includes companies like Toyota, Sony, and
Mitsubishi, which integrates Breakthrough Thinking (BT), World Class
Manufacturing (WCM), and Total Quality Management (TQM). This new movement has
been labeled Concept Management (CM). From BT we get a revolutionary way to
develop product and process improvement ideas by moving away from the slowness
and costliness of root cause analysis. From WCM we get the formal structure
around which the ideas are turned into goals.
From TQM we get the continuous improvement process for idea/change
implementation.

Most firms outsource some
function and many outsource several. We
analyzed the outsourcing practices of 250 firms of various sizes and
industries. Our findings indicate that some functions are outsourced simultaneously
significantly more often than others. As expected, some of these functions fall
within the same area of the value chain. However others do not. For these we
propose explanations based on existing theory and point out areas where further
exploration is required.

In this paper we develop
simple mathematical models for gaining insight into the outsourcing decision
taken by firms. Essentially we capture the impact of supplier's cost structure
and scale economies through quantity discounts offered by him/her, versus the
scale economies enjoyed by the firm through in-house manufacturing. The
conflicts at a strategic decision making level which may arise out of such a
situation present an interesting trade-off at the buyer-supplier relationship
interface especially in the presence of demand uncertainty.

The manufacturing
globalisation evolves through geographic relocation worldwide and distributed
coordination synergistically in manufacturing systems. This paper examines
these two dimensions of manufacturing globalisation based on two empirical case
studies. Firstly, the issues of manufacturing location decisions in
multinational corporations are investigated. The dynamic characteristics for
the optimisation of facility locations are identified. Secondly, three types of
coordination mechanisms in distributed manufacturing networks are analysed. The
leverages come from product, process and management three levels. Finally, the
paper introduces a new holistic framework representing the complex global
manufacturing network systems with geographic optimisation and distributed
coordination characteristics.

For Lead-Acid Battery Assembly Line, Yousef A.Y. Al-Turki, Ph.D., King AbdulAziz City For Science and Technology,
P. O. Box 53726 Riyadh 11593,
Saudi Arabia
Batch scheduling, if done randomly, could be harmful to
productivity. Less time would be available for actual production because more
time would be spent due to setups. In this paper, we present a heuristic
methodology to minimize the batch production setup times. It was then applied
to a real life company in the Lead-Acid battery industry. We present the
experiences gained from it. Preliminary results show that the methodology is
robust and very beneficial. Further, we have investigated the effect of setup
time period and the batch size in terms of units that can be produced during
operation time.

Clemson University, Clemson, SC 29634-1305
Limiting
the scope to MTO manufacturing environments, this paper develops a heuristic,
called DCAP, for allocating scarce capacity, in the short run, to
multiple-product classes. Deploying a decision theory based approach, DCAP
attempts to maximize profit by discriminating between product classes based on
their relative profitability. Efficacy of DCAP is evaluated by comparing its
performance to a base case and an upper bound, under a wide variety of
operational conditions. The results indicate that DCAP is an effective
heuristic in obtaining near optimum solutions and its performance is
substantially superior compared to the base case.

This work analyses how to separate production planning in units of final
product in order to facilitate the future programming at shop level. It uses no linear models to determine
production programming. These mathematical models and an easy-to-use software
can help medium and small companies to reduce improvisation, providing them an
appropriate methodology.
The production disaggregation has been done considering
principally the following criteria: the company policy to satisfy product
demand, maximum and security stock levels, set-up costs and depletion time for
each product. The inputs for this work comes from a real case of aggregate
production planning solved using optimization techniques.

A flexible
flowshop is a generalization of multi-stage flowshop with a number of parallel
machines at each stage. In this study
we analyze a flexible flowshop problem where we minimize total flow time. We present three heuristics which we then
use in the branch and bound method we developed to find the optimal
schedule. Computational experience
reveals that the heuristics are very efficient and the developed branch and
bound algorithm is capable of solving moderate sized problems in reasonable
solution times.

A nonlinear optimization model
based on the restoration concept is used to explore the relationship, for a
serial production line, between safety stock and several factors. The factors examined in the simulation study
include cost structure, variability of final demand, and control strategy
(kanban versus full information). It is
shown that different control strategies
require very different placements and amounts of safety stock for
"good" performance. The trade
off between the use of information and amounts of safety stock needed is
explored under each of the two control strategies and suggestions are presented

In this article, the authors give a broad view on the
productivity issues. To them, productivity is not a simple mathematical
relation between outputs and inputs. It is the result of a large variety of
factors acting combined or independently. To explain this view, elements like
Investments, Manpower, Environment, Quality, Research & Development,
Information Technology, among others, will be treated in a modern and updated
vision. Additionally, tools like Benchmarking, Balanced Scorecards and
Activity-Based Costing will be discussed concurrently to support the idea that
productivity “will come” if the “right path” is followed.

Total Quality Management (TQM)
has been in practice for many years now.
Several American companies and organizations worldwide have implemented
various principles of TQM in their operations.
However, the effectiveness of TQM has not been clearly determined yet
and a review of the TQM literature reveals some mixed results. Some studies show a positive relationship
between TQM and high performance suggesting its effectiveness, whereas others
point to the doubts and apparent failures of the method. This study takes a look at the TQM process
from an effectiveness point of view and attempts to shed some light on this
controversial but highly significant topic.

Using the context of service
firms in China, we tested and found support for the arguments of Crosby (1996)
that conformance quality and productivity are positively related. The results also indicate that enablers such
as service customization, planning, top management commitment and employee
recognition had a significant impact on conformance quality. Service customization had a moderating
influence on the link between quality management practices (e.g., training in
SPC) and both, conformance quality and productivity. Resource management and human resource management were found to
have substitutive effects on conformance quality, but complementary effects on
productivity.

The
"learning community" concept has received widespread attention by
colleges and universities throughout the United States as an innovative
undergraduate teaching and learning process.
At the undergraduate level, most of the curricular applications are in
the general education courses and arts and sciences courses. Very few colleges or schools of
business structure their academic
programs around the "learning community" concept.
This
paper will explore how the "learning community" concept can be
applied to business programs in order to achieve the benefits and goals of
improved academic quality in their programs through curricular coherence,
innovation, and the development of intellectual and social community for both
business students and faculty.

methodology is suggested in this paper, for collecting, filtering, organizing,
formatting and presenting these different pieces of unstructured data, in a data mining-type searching
structure allowing interaction with internal structured data, permitting
dynamical retrieving, manipulation and analysis from the decision makers. It discusses the role of the company’s

The advanced speech recognition technology can provide
solutions to many call centre businesses that require intensive caller-agent
routine interactions. However, a
reliable, up to 98% accuracy, Natural Speech Recognition engine does not guarantee
a successful NLVR application because the recognition engine only works as a
matching function between the speech spoken by the caller and the vocabulary
and dialogue databases. The proposed
paper will suggest a systematic approach to develop a NLVR application to
improve call centre overall productivity.
A logical approach will be to
monitor the accuracy and productivity after the deployment of the
NLVR application in the call centre environment. This paper will also suggest four development stages to ensure
successful NLVR deployment: Design, Trial Application, Pilot Application and
General Deployment. Within different
stages, different performance indicators are employed in order to monitor the
application process. Finally, the
productivity measured can be used to assist call centre management to
efficiently plan and schedule the manpower in order to improve customer
satisfaction.

This paper deals with WIP´s impacts in terms of the Theory of Constraints (TOC) bottom-line measures
(Throughput-Operational Expenses-Inventory) specifically in continuous process
industries, requiring packaging, large-scale raw-materials extraction and
long-run transport chain, like a cement mill plant. These industries typically operate in a push system from the
raw-material source to the packaging area. The main consequence is lacking of
synchronization in the supply chain, resulting in larger inventory and
costs. An approach for the supply
synchronization was elaborated using the principles of the Drum-Buffer-Rope
technique.

Quality control is an
effective tool for identifying and resolving process problems prior to producing
non-conforming product. However,
process variation is also tightly linked to the condition of the production
equipment. Therefore, control of the
process may be improved if quality control methods are supplemented with
equipment maintenance policies. We
investigate coordinating control chart design and maintenance policies based on
economic criteria. By jointly
optimizing the policies, we provide a policy that helps control the quality of
production through both quality inspection and maintenance activities.

We propose a rank-based process control chart that is
distribution-free and does not require any parameter estimations. The non-parametric control chart is based on
the rank distribution of the cumulative sum of individual observations. When the process is in control; the changes
of ranks in successive cumulative sums follow a specific transition probability
matrix in the Markov chain. Using the
chi-square goodness-of-fit test for the Markov chain, we can determine whether
or not the observations come from the process with the given transition
probability matrix. In a Monte Carlo
simulation, we compare the performance of the rank-based control chart with
those of other traditional control charts.

states of the Markov process can be related to Juran's cost of poor quality:
namely, the internal and external failure costs, and the appraisal and
prevention costs. An annual total cost function based on the costs of poor
quality and the four state Markov process is developed.

Acme truck, a manufacturer of
heavy duty trucks, historically generated over 65% of revenues from government
contracts. Significant cuts in defense spending resulted in a major loss of
sales. Acme responded by shifting strategy, making a series of acquisitions
based, in turn, upon a radical change in manufacturing strategy. Operational
restructuring included increased capacity and mix flexibility via line
redesign, new quality programs, and shifts in supplier management. This paper
will present observations from three Acme SBUs which demonstrate both dramatic
improvements in operational capabilities and pitfalls in the change process.
Specific focus areas include manufacturing flexibility, supplier management,
quality, and inventory reduction.

University of Bath, Claverton Down BATH B.A.N.E.S BA2 7AY UK mnsseb@mangement.bath.ac.uk
The need to see manufacturing
as strategic has gained in popularity and importance since Skinner’s major
contribution. However, many
publications concentrate on how manufacturing capabilities need to be Lean,
Agile and to satisfy requirements of Mass Customization but say
little in terms of how operations strategy contributes to achieving these, and
other capabilities. This paper provides
evidence of plants within firms that create and sustain strategic resonance – a
dynamic process ensuring continuous linkages and harmonization between:
The paper concludes that
operations strategy is a vital factor and that, in large firms, strategy needs
to be plant-specific.
TB4A4 Manufacturing Strategy in the
Rio Grande do Sul State Spring Industry, Augusto Alquez Vaz Costa, Ponticia Universidade Catolicia do Rio Grande do Sul,
Rua Mariante 1076, Apto 21, Porte Alegre/RS/Brazil, CEP 90-430-180, rsj2811@pro-via-rs.com.br
This study focused on the Rio Grande do Sul State spring industry. The
objective of the study was the assessment of manufacturing effectiveness based
on the WHEELWHRIGHT and HAYES (1985) four-stage framework. Additionally, the
study contributed to the operationalization of the four-stage approach. On the basis of empirical data, we concluded
that the industry presents, in general, second stage characteristics. The
manufacturing function was seeking to maintain parity with the rest of the
industry.

In many industries.
manufacturers face an increasing need to manage the inventory of raw materials.
work in process, and finished goods in a way that allows them to effectively
meet customer demands. This paper presents a cross-industry empirical analysis
of the importance that different inventory management techniques (EOQ, MRP, and
JIT) play throughout multiple supply chain stages (inbound activities,
manufacturing operations, and outbound activities). It also demonstrates the
effects that the use of these inventory management policies has on supply chain
performance. specifically on the reliance on inventory as a buffer between firm
supply and customer demand and on supply chain velocity (measured as inventory
turns).

In many forecast applications
orders that have been received through the current time period contain
partially complete customer requirements for a number of time periods in the
future. Such lead-time information may exist in a variety of businesses such as
product delivery in manufacturing, beneficiary payments in life insurance,
investment payments in banking and ticket sales in airlines. This paper
describes a model that is designed to utilize such incomplete lead-time data
when forecasting future customer requirements. Results are included from
testing the model. These tests utilize historical records obtained from both
manufacturing and service organizations.

Software is everywhere. It is
embedded in the products and services we buy and serves as the spine for most
organizational decision making processes. When the software industry committed
to "opening" their systems, dynamic software supply chains emerged.
While a lot has been written about the managing hardware supply chains, there
have been few research studies on software acquisition, outsourcing, and supply
chain management. Based on industry focus groups, we present a framework of the
similarities and differences of hardware and software supply chains.

Marketing on Call Centre Operations, Rita
DiMascio, School of Business
Operations Management, University of Western Sydney, PO Box 10, Kingswood NSW
2747, Australia, r.dimascio@uws.edu.au
Though customers can often
contact a firm's call-centre from a Web-page, call-centres often handle these
queries poorly. As the Internet and call-centres are becoming popular marketing
channels, poor management of their interaction will affect the performance of
thousands of call-centres. This study systematically determines how
Internet-marketing impacts call-centre operations by placing the centre in an
organisational-system framework and using semi-structured interviews with
centre managers. It fills a gap in operations management and marketing
literature and helps call centres improve customer service.

University of Southern California, Bridge Hall 401, Los Angeles, CA 90089-0809, rchase@bus.usc.edu
Electronic Commerce (EC) is
creating exciting challenges for service management. Existing models in the literature either do not generalize to
include both EC and traditional encounters or may imply relationships contrary
to current experience. This gives rise
to two fundamental questions: “How does
the Internet affect service?” and, “How is customer satisfaction
affected?” The Service Profit Chain and
C-SQ-P Model provide the framework for our investigation into these questions. We administered an exploratory survey to
firms that utilize both EC and traditional methods of customer contact. We identified commonalities and patterns
that could explain detriments of customer satisfaction on the Internet. The resulting theoretical framework and
research hypotheses can help reconcile the SPC and C-SQ-P views through process
variability (complexity, divergence, and error) and the framework and model is
also sufficiently robust to generalize to any EC business transaction.

Las Vegas; College of Business, Dept. of MGT, Las Vegas, NV, 89154-6009, wisner@ccmail.nevada.edu.
To remain competitive,
service firms must frequently assess customer satisfaction regarding current
goods and services, as well as customer desires for additional goods and
services. Customer feedback forms are
commonly visible to customers when interacting with services such as hotels,
banks and retail establishments. Many
services today though, are attracting customers using the Internet. Customer comments are also garnered in this
way as well, as company web pages are well suited for these types of
standardized forms. Our study
identified the 100 most widely accessed U.S. bank Internet sites for the
purpose of assessing their customer feedback capabilities. The forms were assessed for their overall
design, ease of use, types of encouragement offered for filling out the forms,
and other specific information sought.
Though
customers can often contact a firm's call-centre from a Web-page, call-centres
often handle these queries poorly. As the Internet and call-centres are becoming
popular marketing channels, poor management of their interaction will affect

Today, two emerging business

are attempting to build more engaging experiences for their customers and
customers are increasingly shifting their service business to the
Internet. At the convergence of these
trends, we explore several issues in this paper. How does this convergence change the existing business models,
level of customer participation, environmental relationship or connection, and
brand identity? What does this imply
for effective web site design for services?
How will new innovations enable web based service experiences? What opportunities should “bricks and

Logistic-Benchmarking in the Clothing Industry, Jörg Nottmeyer, Forschungsinstitut fur Rationalisierung,
(FIR) an der RWTH Aachen, Pontdriesch 14/16, D-52062 AACHEN, No@fir-main.fir.rwth-aachen.de
In view of immense pressure
of competition among German clothing companies, it is a basic need for
enterprises to assess their logistical efficiency. Potentials for rationalization often lie in the logistical system
but are rarely recognized by responsibles.
Therefore, a system providing logistical measures of comparable
enterprises is useful. In contrast to a
direct comparison of companies, the instrument of a supra-company comparison
provides an analysis of logistical achievements by means of indexes established
from real relevant measures. This
article describes the new approaches of the specific performance measurement
for the clothing industry.

This paper discusses the
characteristics that ideally all performance measurement systems should
have. Specifically, the paper
introduces the means-end hierarchy as a way of discussing the shifting emphasis
from measures at a high level of abstraction (development of corporate
strategy, for example) to specific performance measures used to control shop
floor activities. The theoretical
requirements are confronted with the in-depth analysis of the performance
measurement systems of two large multinational corporations. These examples showed that the same
theoretical guidelines can be achieved using very different approaches and
systems that reflect the unique requirements and pressures under which these
corporations operate.

It is generally accepted in
the management literature that a predictable relationship exists between the
cumulative production volume and the time required to complete a batch or an
individual unit of product. T. P.
Wright first reported an exponential learning curve phenomenon for airframe
manufacturing in a classic paper in 1936.
Numerous articles in the medical literature have described a strong
volume-outcome relationship for various procedures and conditions from neonatal
intensive care through pancreatic cancer surgery and trauma surgery. Physicians and medical scientists have found
that the learning curve phenomenon is as true in health care as it is in
manufacturing.

Survey
data suggests that between 40 and 60% of companies will have significantly
changed their measurement systems between 1995 and 2000. Most of these initiatives, however, appear
to be static. Consideration is being
given to what should be measured today, but little attention is being paid to
the question of what should be measured tomorrow. Measurement systems are dynamic.
They have to be modified as circumstances change. Yet few oganisations
appear to have systematic processes in place for managing the evolution of
their measurement systems and few researchers appear to have explored the
question - what shapes an organisation's measurement system. The research
reported in this paper seeks to address this gap in the literature by
presenting data that describes the forces that shape the evolution of the
measurement systems used by different organisations.

TC2A1 Expanding
the Boundaries of the Operations Strategy Process: Lessons from Corporate
Strategy, David L. Barnes, Open
University Business School, Walton Hall, Milton Keynes, MK7 6AA UK, d.l.barnes@open.ac.uk
Consideration of process in
operations strategy has changed little since Skinner's original prescriptive
model. This was firmly rooted in the dominant top down, rational corporate
planning paradigm of that era. In contrast, corporate strategists have
subsequently broadened their thinking about the strategy process to develop
both descriptive and prescriptive models. These now encompass a wide range of
perspectives (cultural, political, cognitive, etc.). This paper draws on case
study research of the operations strategy process in practice, to argue that
operations strategy can learn much by expanding its boundaries to embrace the
concepts and methods of corporate strategy.

, Kenneth W. Platts, Department of Engineering, University of Cambridge,
Mill Lane, Cambridge, CB4 2HA, kwp@eng.cam.ac.uk
Writers on resource-based and
competence or capability theory occasionally hint or assume that these theories
are related. There is, however, little
in business or operations strategy literature that explicitly integrates these
theories. In this paper we assemble an
architecture, which integrates theory from both literatures, including the
following concepts. The competences
that customers recognize, like rapid product delivery, are often reliant on
supportive meta-competences, which may be technological or organizational. Resources are the building blocks of any
competence and the performance of a competence is partly dependent on their
configuration, which is heavily dependent on the competencies of managers and
staff.
The core design of
implementation is based on strategic, systemic and shopfloor considerations,
using the so-called “3S” model. The 3S
model was evolved in a climate of management-shop floor mistrust: the South
African industrial scene of the 1990's.
It incorporates principles of productivity management as well as the
Terry Hill approach to manufacturing strategy.
More recently the 'elements' of David Upton's (1998) approach to an
improvement strategy have been incorporated in the model, together with the
'innovation-values fit' of Klein and Sorra (1996). Case study research has yielded practical insights. The revised model is presented.
This paper seeks to answer an
old question: whether there is really a serious difference between
manufacturing strategy and international manufacturing strategy. Based on
twenty detailed case studies in four sectors, the paper presents three typical
cases of manufacturing globalisation in multinational corporations and
illustrates some new challenges when manufacturing crosses the borders and
becomes a global player. It analyses the classical manufacturing strategy
framework and the new challenges that framework faces. Finally, it introduces a
new framework tackling the international manufacturing strategic issues and
guiding the future research work.

Model to Explain How a Call Centre Evolves, Rita DiMascio, School of Business Operations Management, University

One would expect that call
centres would be highly valued within their organisations because of their contstant
contacts with the customer. Yet this is not so. The status of these centres
vary across organisations from 'low value' and a necessary evil to cutting
costs, growing markets. This study aimed to explain why their status varies
across organisations. A model was built
which shows how call centres evolve in status. This model could well be applied
to the manufacturing function which Hayes and Wheelwright [1984] have noted
also developed in stages.

This paper presents a model
of electronic auction sales strategies and discusses their impact on
operations. Three strategies are
identified: substitute, selective, and access.
The substitute strategy used electronic auctions as a routine sales
channel. Selective sellers sell
products at auction only to accomplish specific goals such as supporting
regular channels or to control inventory levels. The access strategy uses electronic auctions as a marketing tool
to provide exposure to customers who might not otherwise come in contact with
the company products. The differing
demands on operations functions such as scheduling, inventory control, and
shipping are discussed.

was to identify formation advantages and drawbacks. A detailed questionnaire
was applied. Among the many advantages we may highlight technology access.
Results lead to the conclusion that small and medium telecommunication owners
in Brazil are not used to join themselves for a common goal and problem
solving. The concept of mutual collaboration as a worldwide adopted alternative
for companies grew interested in acquiring a better cooperation knowledge in
order to survive and allow technology sharing.

Manufacturing institutions
are practicing a new, more dedicated way of conducting short and long-range
business. This new approach positions each firm to do what it does best while
at the same time spreads the risks of asset ownership and minimizes the risks

As the research in the area
of Supply Chain Management progresses, there is a need to develop units of
analysis that capture the complexities of and interrelationships within supply chains.
Utilizing survey responses from a diverse group of 336 U.S. manufacturing

Flexibility is often seen as
a "panacea" for manufacturing companies experiencing increasingly
complex and turbulent environments. One significant source of flexibility in
manufacturing plants derives from integration with supplier and customers in
the supply chain. However, little empirical research has been carried out to
show the link between effective supply chain management and manufacturing
flexibility. This paper reports the results of an empirical research study
carried out in two LTK manufacturing companies in the electronics and household
goods sectors. Drivers for supply chain flexibility are identified and a model
that relates supply chain strategies with increased manufacturing flexibility
is developed.

As automobile manufactures
are striding toward the lean direction and demand JIT logistics from suppliers,
suppliers with lean systems in place are more likely to be incorporated into
the total system. For manufacturers,
supplier support is a key element for the successful implementation of lean

Given the shortage of

should be organised is to study the mistakes which companies have made in their
dealings with one another. This work draws upon some elements of systems theory
and the less well-known theories of cognitive neuropsychology. The paper
investigates instances where networks have become flawed and seeks to learn
more about networks as a consequence of observing these mistakes.

davis@clemson.edu, Fidelis Ikem, Virginia State University, fikem@vsu.edu.
Frequent changes to
production schedules in a material requirements planning (MRP) environment can
lead to confusion at the shop floor level and reduced productivity. One
approach suggested in the literature to reduce instability is to introduce
safety stock at the master production schedule level to act as a buffer against
differences in actual and forecast requirements. Safety stock reduces the
impact of deviations of actual demand from forecast and thus, reduces the need
for changing the MPS schedule. Contrary to prior research, our research
concludes that safety stock did not necessarily improve schedule instability.
This paper is intend to formally investigate the effectiveness of carrying
safety stock to reduce schedule instability when demand is uncertain over the
planning horizon. Simulation experiments are conducted to determine the impact
of safety stock under a wide range of operating conditions represented by
various levels of demand uncertainty, cost structure, lot-sizing rules,
planning horizon length, and frozen interval.

of spare parts, for example in a large industrial facility. Lamps, standard
o-rings and bearings can frequently have a stable well-behaved demand but in
many situations the bulk of the investment in spare parts inventory is exactly
composed of parts the demand of which is anything but stable. Lumpy-type of
demand is frequently found in corrective maintenance. This paper proposes the
use of modern simulation software in helping practitioners define inventory
management systems parameters - e.g. safety stocks and reorder points for spare
part items whose demand follows a difficult to predict lumpy pattern, using a
principle which resembles but goes beyond the focus forecasting logic in the
sense that it incorporates numerical search procedures.

Optimal Policy of an Inventory with ARMA Lead Time Demand, Kal Namit, Winston

Generally in determining
the optimal policy of an inventory model with a stochastic demand, one has to
deal with mean rate of demand, standard deviation, safety factor, forecast and
lead-time. The calculation of the
re-order point is typically based on the assumption that the mean rate of
demand is deterministic and is a function of time. This is far removed from reality. In this research paper, we will look into the calculation of
reorder point, safety stock and order quantity of an inventory based on the
assumption that the process generating demand data can be forecasted by ARMA
Box-Jenkins model.

Competitive
pressures have caused a large proportion of firms to re-think their strategies,
and to develop their capabilities.
Capability development requires an understanding of the configuration of
operations, an alignment with customer requirements and an appreciation of the
standards of performance (best practice) exhibited by competitive
companies. While each of these issues
has been dealt with in the strategy literature, little work has been undertaken
to integrate these perspectives into a useful operational model. This paper presents a theoretical model
which integrates these strategy perspectives with a model of organizational
configuration. The paper describes the
use of this model to support process improvement in Small and Medium sized
Enterprises (SMEs) in three European countries.

The proposal of this paper is of
presenting a Methodology to identify functions that add values to the systems
ERP's (SAP, QAD, SSA, JDEDWARDS, MICROSIGA, MAGNUS). This methodology was
divided in 8 phases and it was developed using the ideas of the techniques of
“Analysis of the Value” which is used broadly all over the world in the
industry. The methodology suggests an
important work to help the companies to identify special functions. So much the
customers as the users which need to do use of those “New Functions” that are
not still available or incorporated in the systems ERP ', they can use it. After
applying the Methodology in 25 companies in the Brazilian market, we obtained
ourselves the main functions that add values to the systems ERP's as a result
of the research.

flexibilization in Brazil. An important
question appears: if RSI have origin at work, and the tendency is changing work
through production flexibilization, what would happen to the RSI?

This paper develops and
validates new methods for measuring volume or output flexibility. Other
researchers use variability in sales to measure flexibility and conclude that
small firms are more volume flexible.
But, variability in sales essentially measured diversity in the
environment, and, therefore, it may not be a valid measure of flexibility. Our
measures consider the combined impact of both the firm’s technology and
environmental diversity, by incorporating process properties such as inventory
levels and cost incurred in meeting sales variation. Using 20 years of
Compustat data, our results show that small firms may actually be less volume
flexible than large firms are?

discussed. However, little empirical research has been carried out to explore the
mechanisms available to plants to achieve such flexibility and their degree of
usage. This paper reports the results of a major survey, which identified the
mechanisms used to achieve labour capacity flexibility in UK manufacturing
plants. Identified mechanisms are not sector dependent, but they do depend on
specific market conditions, and their perceived costs and benefits.

process. It is based on two surveys, with 284 and 324 responses respectively,
to Swedish manufacturing companies and a case study conducted at a Swedish
manufacturing plant. The findings from the surveys describe the present level
of investment in various strategies, techniques, tools, and organizational
design for equipment maintenance. They also explore the impact of differing
maintenance approaches on contextual factors and operational performance.
Findings from the case study describe how a process oriented and proactive
maintenance approach was implemented in a new plant, and explain the effects of
the new approach.

The paper provides a
conceptual model of a GSCRP – Global Supply Chain Resource Planning software.
It involves the detailed development of supporting tools and it's associated
technological and organizational processes to enable the GSCRP software
implementation.
The operating mode of each
element that compounds the pillars of the GSCRP software is described in
detail. The investment in technology and organizational changes as well as the
interface with the ERP – Enterprise Resource Planning software is also
discussed.
The model also points out
information access problems. Several levels of access based on information
needs of each firm in the supply chain were created.

This paper proposes a
graphical and analytical framework to develop global supply chain performance
measurements. As well as, many specific performance measurements are presented
in order to illustrate the model. The model compares planned performance
measures with the current ones. In this manner, decisions may be made through
the knowledge of how far the supply chain performance is of its expected goal.
Consequently, the model allows the monitoring of supply chain improvement processes
eventually implemented, as the inclusion of a new supplier. Therefore, another
contribution of the model is the evaluation of suppliers' performance measures
according to a set of selected minimum performance criteria.

Graduate School of Management, Department of Marketing and Supply Chain
Management, East Lansing, MI
48824-1122, dmstew@pilot.msu.edu
Recent work has highlighted an
important, yet mostly overlooked cause of
service failures – a mismatch between the customer’s chosen script and
the service of delivery system. This
results in the customer engaging the service under a set of rules of behavior
and expectations of performance that differ from those the service provider
actually offers. Although the error is
on the part of the customer, it is attributed as a failure of the service. This paper will address the causes of
mismatch, and provide guidelines for script sensitive design, the elicitation
of desired scripts, and handling of intentional mismatches.

Lawrence D. Fredendall, Clemson University, 123-A Sirrine Hall, Clemson,

In services, employees who
have customer contact directly influence customer satisfaction. It is expected that higher job satisfaction
and organizational commitment on the part of customer contact personnel will lead
to higher customer satisfaction. Since
teams reduce isolation and improve communication among employees, it is
expected that customer contact personnel who are part of teams will have higher
job satisfaction and higher organizational commitment and consequently, will
generate higher customer satisfaction.
This is examined in an empirical study of automobile dealer service
garages. There was a statistically
significant relationship between profit, productivity and job
satisfaction.

deemed important for customer service, a teller-staffing plan was developed
through the use of a multi-channel, single phased queuing system. The queuing study resulted in a staffing
plan that achieved all of the design parameters, and did not result in any
additional cost or personnel layoffs.

resource. However, despite large
investments in information technology, many organizations fail to achieve
significant returns. This paper
analyzes the investment, implementation, and utilization of IT through the
introduction of a formal dynamic model of a worker information-technology
system. We examine the manner in which
management policy during the implementation process impacts the firm's
long-term performance level. We
investigate management decisions concerning investment in technology upgrades,
investment in work force training, and the timing of the information technology
upgrade.

TD6E1 Order Review
and Release (ORR) Usefulness in a Flow Shop, Ravi Paul, Clemson
University G07 Sirrine Hall, Clemson, SC 29672, ravip@clemson.edu
Use of Order Review and
Release (ORR) mechanisms as an effective means to control WIP is controversial.
Some writers and studies have asserted that order release is very important to the
successful operation of the entire manufacturing system. While some others
argue that the use of good dispatching rules makes ORR a much less needed
function. Also, most of the studies done to date are in a job shop environment.
A consistent and well-defined theory about what shop conditions are most
important to the realization of benefits from ORR in a Flow Shop environment
does not exist. This study hopes to
provide a basis for the determination of ORR usefulness in a flow shop. This
can then be used to compare with the results obtained from previous job shop
studies. Another important objective is to investigate the interaction between
ORR and other shop conditions such as dispatching rules, due date tightness,
and load limits. And finally, it hopes to shed more light on the WIP/workload
balance vs. due date delivery performance trade-off issues clearly seen in the
previous studies of this nature.

This article proposes a
supply chain methodology to evaluate acquiring, processing and sales factors,
both in quantitative and in qualitative terms. The qualitative parameters is
dealt by means of the AHP method. Usually, the qualitative factors are not regarded
in decision-making process to select suppliers. Accordingly, a chart of
factors, including the external ones, that influence the selection process is
also provided, together with their related performance measures. The proposal
is illustrated through its application in a manufacturing process case study.

When a firm tries to
establish a new supply chain with new product, it is very difficult to persuade
suppliers and distributors to share the vision and the the risk involved.
Behind any partnership agreement or contract what always matters most is how to
share the risk o the new venture. Distributors' practice of free return and
suppliers' practice of quantity discounts are not helpful for partnership. We
analyze a PC manufacturer case, which shows us that chain leader has to take a
bigger risk to build a new supply chain. A better approach is suggested using a
simple model.

In this paper, we investigate the operational
benefits of vendor-managed inventory (VMI) under considering transportation
costs. The supply
chain considered in this study is consisted of one capacitated supplier and N
retailers. Customer demands are stochastic and occur at the retailer sites. An
integer programming model is built to handle this problem. The model’s optimal
solution is obtained by the heuristic method. We find that the transportation
cost has a significant effect on the performance of the supply chain. The
conclusion generates insight into the operational benefits of VMI as well as
understanding the value of VMI programs and can guide the practitioners to
implement the VMI.

Developing small firms in emerging economies to
become suppliers of high tech global industries. The recent movement of high
tech global corporations toward emerging economies such as Brazil created the
demand for the development of local suppliers. Although the subject is not new
the conditions under which that is taking place are rather different from previous
experiences. The differences are mainly related to the overall speed of change
and the level of quality requirements typical of industries such as computers
and telecommunications. Thus, the difficulties that large foreign firms encounter to develop local
suppliers are magnified. This paper, based on follow up studies on the creation
of three supply chains, presents some guidelines to facilitate: i) the way that
foreign firms have to search, approach and evaluate potential local suppliers;,
ii) the way that local firms have to assess the trade-offs when targeting to
become global
suppliers.

teacher spends 75% of the working day in communication. Teacher, students and curricula are the
three major components in any educational institution. Buildings, books, laboratories etc. are the
one which aids the teaching process.
The most important of all is the art of teaching so that students are
engaged in the process of learning. The
success depends on new methods adopted in teaching which is the communication
between a teacher and the student. The
present investigation was carried out in a technical institute to study the
following:
1) Preparation and

This paper examines how institutions
of higher education might operationalize performance evaluation as related to
research, teaching, and service. An
Analytic Hierarchy Process (AHP) model is developed that allows decision makers
to couple performance evaluation and academic rewards offered by institutions
of higher education. The academic
reward systems might include promotion decisions, merit pay, tenure, long-term
contracts, and annual rewards of excellence.
The model could be used to make judgment on the qualification of candidates
for such reward systems considering one (some rewards are given for achievement
in only one area), or all three components of research, teaching, and
service.

College of Business and Economics, Memphis, TN 38152, Smehra@memphis.edu
The Balanced Scorecard (BSC)
concept was proposed as a comprehensive philosophy of managing business
operations. Focal points of action
required detailed planning by all functional areas, and all personnel in each
area, towards reaching consensus on various goals, targets, measures, and
initiatives. This planning process focused
upon four key perspectives of success faced by various businesses—Financial,
Customer, Internal Processes, and Learning and Growth. In our view, an important perspective has
been left out of the BSC philosophy, i.e., one of the Environment. In this paper, we extend the BSC philosophy
to include this additional focal perspective, and justify its inclusion in the
total scheme of managing operations for enhanced performance.

The classical solution to the
problem of trading completion time of a network of tasks to increased cost is
now widely available. A new approach to solving this problem is presented in
this paper that demonstrates a truly interactive scheduling concept involving
object data base manipulation and the programming techniques through active-X
linkages. While a demonstration of the approach is based on a simple case
study, the potential for its application to huge network diagrams will be the
key finding of this paper.
TE3E2 Price Discount Based On
Options As An Inducement Of Information Sharing In Supply Chain Management, Fujun

Information sharing, as an
important, supply chain coordination method, is investigated by numerous
researches. The erstwhile studies show, however, that retailer cannot benefit,
or benefit much less than supplier, from the supply chain through information
sharing. This situation heavily dampens retailer's incentives to share
information. Price discount is a common method to coordinate the supply chain,
but this paper shows that simple price discount cannot elicit the valuable
information from retailer and improve the performance of entire supply chain. To
deal with this problem, this paper employs price discount based on options to
induce retailer's valuable information sharing.

Total Quality Management
(TQM) philosophy recommends eight practices to improve the quality which are
management leadership/quality policy, training, product/service design.
supplier quality management, process management. quality data/reporting,
employee relations, role of the quality department. Since end product quality
depends on the procurement of the defect free parts, part quality across the
supply chain is particularly important. Supply Chain Management (SCM) approach
emphasizes coordinated efforts across the supply chain to achieve a global
optimum. This paper develops a decision making tool by combining these two
philosophies to help practitioners decide which links (suppliers) in the chain
should be improved and which TQM programs (training, process development, etc.)
should be selected to get the best results under a limited supply chain
development budget. The Dynamic Programming based tool selects the right
supplier development programs that minimize the scrap across the chain.

TE4E1 Application of Multi-Attribute Theory on
the Operationalisation of a Make-or-Buy Framework, Laura Canez,

The make-or-buy question represents a fundamental
dilemma faced by many companies. However, companies often fail to consider the
strategic implications of these decisions and the need to take account of a
wide range of factors other than cost. In order to address such a decision a
make-or-buy framework, which encapsulates all relevant factors has been
developed. The operationalisation of the framework has been undertaken using
Multi-Attribute Decision Making theory (MADM). This paper describes the
operationalisation of the framework and discusses the practical implications of
the application of this theory. An in-company case study is presented to
illustrate such issues.
TE4E2 A Content Model of Information Exchange in the Supply Chain, Jose V. Gavidia, University of Texas-Pan American, College of

One of the components of
supply chain management most widely cited in the literature is the use of
information systems to communicate information to other supply chain members.
As firms evolve from competitive supplier relationships to dyadic cooperation,
to supply chain integration, there is an increased need for information sharing
that will allow synchronization, coordination, and reduction of waste. Recent
advances in information technologies make possible the assumption of perfect,
real time communication across firms. This paper analyzes the content of the
information to be exchanged, and proposes relationships between information
flows and supply chain performance measures.
TE4E3 Virtual Logistics in Virtual

The integration of management
processes across organisational boundaries is a key postulate of modern
logistics or supply chain management. In recent publications the term 'Virtual
Logistics' has been used to describe a new approach to logistics management.
Based on the results of a case study that was conducted in Germany the core
elements of this new logistic management concept are explored. Several
distributors of roller bearings who formed a horizontal virtual organisation,
Bearing Partners, are using a 'Virtual Logistics Centre' as co-ordination and
integration tool for logistics management processes. The findings of this study
reveal that the Virtual Logistics Centre was developed as a tool to manage
logistics activities within the Virtual Organisation and are rooted in the
common strategic objectives of its members to share high value logistics
resources and to pool purchasing power. A key of 'Virtual Logistics' is the use
of information and communication technology (ICT). Furthermore the study gives
evidence that the formation of a virtual organisation is rooted in close
co-operation based on mutual trust and long term commitment.
TE4E4 Controlling the Variability
in the Global Supply Chain Management Network Through Internet Web-Based
Technologies, Pedro Reyes, 13776 Heartside
Place, Farmers Branch, Texas 75234, preyes@gi.com
Global strategic advantage is
when all conditions of managing the supply chain are integrated so that
communication flows forward and backward throughout the chain. However, there
are difficulties in an effective network due to variability along the supply
chain. This variability affects the flow of material throughout the chain.
Sources of variability stems from the supplier's network, the organization's
manufacturing process, or the customer's network. Controlling variability
requires innovative approaches by linking the information systems of suppliers,
manufacturers, and customers through Internet web-based technologies providing
daily updates to supply-demand data for controlling and planning inventory
replenishment throughout the entire system.

Title: A Focus on
Integration: Helping Students Put the Pieces of the OM Puzzle Together
Chair: Alan
Betts, Warwick University
In the teaching of Operations
Improvement the development of process knowledge is presented as an important
central concept. Translating the
concept into action may often prove to be a challenging task for educators and
learners alike, often relying on the use of illustrative examples to explicate
the core philosophy. As part of a
series of exercises to demonstrate the importance of developing Process
Knowledge (Bohn 1994) we developed an interactive compluter simulation of a
call centre operation in which a number of competing teams of 5/6 members are
formed, each member having a functional responsibility. Following their preparation of an influence
diagram, the teams use the computer simulation to enhance their process
understanding through their development of structured experiments.

This
work reports a case which intends the teaching of the Production and Operation
Management in post graduation courses.
The case and its derivations are the central theme of the course,
linking several specialty areas, as planning, programming, purchases, stocks,
logistics and maintenance, facilitating the exploration of occurrences in the
productive system. This leads to the
necessary knowledge of the concepts of the Production and the other areas,
configuring a systematical practice, allowing to exercise the reaction face to
the events of a complex reality.

This
paper presents a spreadsheet based simulation game for teaching/learning
production planning and control concepts such as forecasting, material
requirements planning, order review and release. In this game the student plays the role of a production planner
managing two products, for which customer orders are placed in variable
quantities throughout the week. The
student builds forecasting and material requirement planning systems to help
them in their task. Initial student
responses have been favorable.
