Chopra, S. and P. Meindl, (2004), Supply Chain Management: Strategy,
Planning, and Operation, Prentice Hall, New Jersey.
Sunil Chopra and Peter Meindl have
recently updated their Supply Chain Management book (2.
edition published by Prentice Hall). The new edition is more
comprehensive than the previous edition; it includes basically
two new chapters on Sourcing and Pricing and
Revenue Management
. Discussion of design options for a
distribution network of Chapter 4 is also new material. The rest of the new edition is very similar to the first
edition. This similarity between editions hopefully justifies me as a legitimate reviewer because I have used only
the first edition in three sections of an elective 3-credit course at a business school. Practically, the class populations
were split equally between MBA students and MS students. The students generally had above-average
quantitative background with regard to ordinary business school students. My perspective on the book is partly
shaped by my students' reactions. I believe that this perspective is a healthy one as a "good book" should
teach well to a novice reader. Below, I go over the book in detail and discuss what readers can and cannot find
in the book. At times, I take the liberty of suggesting additions/deletions of some topics or reordering some topics.
The new edition, like the old one,
examines supply chains in six parts. The first part deals with
Building a Strategic Framework to Analyze Supply
Chains. This indeed is a good start to give a top-down
view to readers. It starts a smooth transition from the
qualitative discussions of an average business school course
to more quantitative discussions of a supply chain course.
Moreover, the students warm up with the subject matter while
the three chapters of Part I are discussed. In Part I, the
concept of a strategic fit between customer wishes and supply
chain capabilities is very important. On the other hand, one
can quickly skim over the sections of Process view of
supply chain and Expanding strategic scope
.
The second part is mainly on logistics:
location and transportation analysis. This part used to come
after inventory chapters in the first edition. Since outcomes
of infrequent decisions typically become inputs for frequent
decisions, infrequent decisions should be discussed first,
e.g. location decisions should come before inventory
decisions. Ordering decisions (effectively chapters) according
to frequency eliminates potential confusion as to how
decisions are related and what is their relative chronology.
Hence, I applaud authors' decision to discuss logistics
earlier. Location chapter includes interesting examples of
inventory and transportation cost trade offs. These examples
deserve a careful reading because they emphasize the concept
of integration (system-view) which is a keystone for supply
chain management. On the other hand, location (Chapter 5) and
transportation (Chapter 14) could have remained next to each
other. The relegation of transportation may be due to its
inclusion of routing type combinatorial topics that may not be
appropriate/interesting for some readers. Those readers may
skip parts or all of the transportation chapter but the others
can read the transportation immediately after the location.
Speaking of the placement of chapters, I agree with the
authors that network design decisions under uncertainty belong
to Part II. This discussion was provided under the
Financial evaluation chapter in the first edition.
Authors use the methodology of decision trees to solve two
examples here. With these examples, instructors may also
illustrate how simulation can be used instead of decision
trees. This is now made possible by an appendix in the new
edition: Simulation using spreadsheets. If this
appendix is pulled into Part II which seems possible with
little effort, readers can be presented with a comparative
discussion of decision trees and simulation. Such a comparison
adds to the value of the book. It is helpful to practitioners
who, for their specific problem, may need to make an
"unbiased" choice between these techniques unlike some
academicians who, for unclear reasons, tend to advocate one
method over another. Lastly, I feel that some sections of the
book were written quickly so inconsistencies in exposition
occurred. For example in Section 4.3. Design options for a
distribution network
, the names
and the order of the six options are not consistent with the discussion in the section and column names in Table 4.7.
Part III of the book is Demand and
Supply Planning . It starts with a chapter on forecasting which discusses
standard time series techniques. Standard time series techniques are not central to supply chain management, so
they can be skipped. Besides, it is likely that the readers of this book are already exposed to some forecasting
concepts. The last two chapters include an extended linear programming formulation example that illustrates
production planning and the sensitivity of the solution against different demand scenarios. Different demand scenarios
are obtained by giving price discounts in different months. The challenge here is to generate these demand
scenarios in a meaningful way that relates demands to prices. Assuming that scenarios are known a priori, I am
afraid the book does not meet the challenge. I am not aware of literature that directly deals with forecasting the
demand under different discount schemes. However, the bar need not be set so high; a common sense approach can
satisfy a practitioner's needs. The readers will perhaps appreciate a section on demand forecasting with pricing
more than the current forecasting chapter. Part III briefly introduces capacity management strategies for unstable
demand. However, these strategies strongly affect the profitability of a company over a long run so they can be
discussed in more detail.
Part IV and V constitute the core of
the book and they make it truly a Supply Chain book, say as
opposed to a logistics book. The first two chapters of Part IV
are inventory planning for certain and uncertain demands. The
last chapter of Part IV first presents the news vendor problem
and then goes in to Section 12.3 Managerial Levers to
Improve Supply Chain Profitability. This is a very
important section and includes the concepts of improving
forecast quality, quick response and postponement. Readers
will enjoy reading this section and more importantly will gain
practical knowledge. The topics in Section 12.4 Supply
Chain Contracts are also important but this section is
very short for readers to understand and appreciate. An
important aspect of supply chain management is dealing with
multiple players with different, possibly conflicting,
objectives. Contracts are used to align these objectives for
the profitability of the entire chain. Thus, contracts
(buy-back, revenue sharing, quantity flexibility) deserve more
discussion. In the next chapter, (Chapter 13 in Part V)
authors revisit contracts and provide more discussion. The
reason for discussing contracts in two different chapters is
perhaps a historical one as the first edition did not have
Chapter 13. I believe Chapter 13 is written and is simply
appended, but it preferably should have been integrated with
the presentation of contracts in Chapter 12. In spite of my
critique, I must point out that a semi-quantitative
presentation of contracts is not trivial so many supply chain
books avoid it. The next chapter is transportation which I
allude to above. The final chapter of Part V is a new one
called Pricing and Revenue Management
, a comprehensive but disappointing title; it basically talks about customer segmentation
and overbooking (say, an aircraft to account for passengers not showing up). Readers expecting to find a discussion
of dynamic pricing or discounting will be disappointed.
The final Part is Coordination,
Information Technology and E-business . Coordination chapter is an important
one as it includes the discussion of the bullwhip effect. The discussion and the practical examples are comprehensive,
they are also somewhat qualitative so can be more accessible to readers. However, for readers, who hear
about bullwhip effect and want to see it in the first chapter of a supply chain book, I advise some patience because
the bullwhip effect is presented in the 16th chapter of this 18 chapter book. Instructors must be careful to reserve
enough time towards the end of a semester to cover this chapter. The last two chapters provide a qualitative but
technology oriented discussion of Information systems and E-business. The latter topic is more relevant than the
former for supply chains. However, both topics are covered in other books/courses in more detail so I think hardly
anybody will read this book for its last two chapters.
At the end of chapters, the reader can find qualitative discussion questions and quantitative exercises. The
exercises help the reader to better comprehend the subjects and allow the instructors to measure students' understanding.
There also are 2-3 page case studies at the end of some chapters. These cases are too short for
an in-class case study discussion so instructors may bring in longer cases from other sources. Some quantitative
derivations are postponed to the appendices at the end of the chapters. Thus, the flow of the presentation is
kept smooth while giving a chance to an interested reader to see the details. Discussion questions, exercises, case
studies and appendices help the book to qualify as a "good textbook".
Is this book for you? If you are a curious practitioner but the only time you hear the term supply chains is
on TV commercials, this book is too detailed for you. If your job requires knowledge of supply chains but your
background is not in engineering or management, you should read this book only after some introductory texts.
If you have an engineering or management background but want to refresh/update your knowledge, this book
is just for you. As a textbook, it can be used at junior graduate or senior undergraduate level. However, the
readers must have earlier exposure to linear programming and probability. The book can be used at a business
or engineering school by adjusting the mix of quantitative and qualitative discussion.
Unlike most others, the book attempts to provide a quantitative discussion of supply chains. The attempt is
not entirely successful due to organization of some ideas but it is in the correct direction. It may take 1-2 more
editions to succeed in this attempt. Some readers may correctly think that addition of several appendices will
facilitate the understanding. For example, an instructor can supplement the logistics chapters with linear and
integer programming notes, and inventory chapters with probability notes. However, I believe that authors chose
to keep the focus on supply chains by excluding such appendices and I support their choice. Readers interested
in a stronger linear programming focus can refer to other books, say J. Shapiro's "Modelling the Supply Chain".
This 567 page book touches upon almost all the supply chain topics and can easily be voted for one of the
most comprehensive books. Thus, you will find a discussion on any topic you ever wanted to know about supply
chains. However, the question is whether you can learn all these topics by reading this book. Maybe not; you
may need several point of views or books. But if you insist to read only one book on supply chains, this is it. Enjoy!
