Supply Chain Analysis: A Handbook on the Interaction of Information, System, and Optimization is a carefully developed work focused on the analysis of supply chain interaction issues in emerging markets and industry sectors. It is a leading-edge handbook that will emphasize where little work has been done and where the “rubber meets the road” – the supply chain process, information, and systems integration. These are pertinent issues facing practitioners and researchers in today’s business environment.This is a gap-bridging handbook that analyzes interaction issues from both the research and practitioner sides. The result is a volume that examines and provides practical solutions on interaction issues while being firmly grounded in research principles.An outstanding team of editors: Chris Tang is well-known and highly regarded in the area of Supply Chain Management. He is both a department chairman and the Edward Carter Professor of Business Administration at UCLA Anderson School; Professor Wei is the Dean of the Faculty of Business at the City University of Hong Kong, and is an eminent scholar in the area of Information Technology; Professor Teo has extensive experience in the area of Supply Chain Management and Optimization, and he is with the NUS Business School at the National University of Singapore.

To compete in today's volatile market with rapidly changing consumer tastes and erce competition, companies in the manufacturing and service industries are - ploying new mechanisms to increase sales, market shares, and pro ts. As an - fective mechanism to segment a market comprising of consumers with different needs, preferences, and willingness-to-pay, many rms have used product (or s- vice) variety with different price points to serve different segments of the market, see Ho (1998). Ideally, the price of each of these products (or services) targets a particular segment of customers. For example, airlines often use different terms of sales (refundable/non-refundable, upgradable/non-upgradable, direct/connecting ight, etc. ) to sell economy class tickets at different prices. Likewise, retailers - ten sell the same product at different prices in different channels (company's own web site, dealers' web sites, or company's physical stores) or at different times (- fore, during, and after the selling season), see Talluri and van Ryzin (2005). Ample academic literature in Operations Management and other areas considered these strategies.However, as consumers become more knowledgeable about the product, pricing, organizational and operational policies that the companies deploy for pr- ucts and services, their purchasing begins to change dramatically. In the academic Operations Management literature, consumer demand is often assumedtobe exogenous so that demand functions are usually modeled as well de- ned and exogenously speci ed functions of price and/or other product attributes such as quality.

The proliferation of new products has become a common phenomenon in today's business world. Most companies now offer hundreds, if not thousands, of stock keeping units (SKUs) in order to compete in the market place. Companies that expand their product and service varieties now face a new set of problems: accurate demand forecasts, controlling production and inventory costs, and providing high quality delivery performance. In addition, marketing managers will often advocate widening product lines for increasing revenue and market share, but increasing product lines can also decrease the efficiency of manufacturing processes and distribution systems. Hence, firms must weigh the benefits of increasing product variety against its cost and determine the optimal level of product variety to offer to their customers. This text examines the interrelated problems between the marketing and production functions in industry, and through a series of research survey papers by leading scholars in economics, engineering, marketing, and operations research, the book addresses the following questions: Why do companies extend their product lines? Do consumers care about product variety?Will a brand with more variety enjoy higher market share? How should product variety be measured? How can a company exploit its product and process design to deliver a higher level of product variety quickly and cheaply? What should the level of product variety be and what should the price of each of the product variants be? What kind of challenges would a company face in offering a high level of product variety and how can these obstacles be overcome? The solutions to these questions are drawn from multiple functions and a variety of disciplines.

From the Foreword by Marshall Fisher, The Wharton School, University of Pennsylvania:As generation of academics and practitioners follows generation, it is worthwhile tocompile long views of the research and practice in the past to shed light on researchand practice going forward. This collection of peer-reviewed articles is intended toprovide such a long view.This book contains a collection of chapters written by leading scholars/practitionerswho have continued their efforts in developing and/or implementing innovativeOR/MS tools for solving real world problems. In this book, the contributors sharetheir perspectives about the past, present and future of OR/MS theoretical development, solution tools, modeling approaches, and applications. Specifically, this book collects chapters that offer insights about the following topics:• Survey articles taking a long view over the past two or more decades to arriveat the present state of the art while outlining ideas for future research. Surveysfocus on use of a particular OR/MS approach, e.g., mathematical programming(LP, MILP, etc.) and solution methods for particular family of application, e.g.,distribution system design, distribution planning system, health care.• Autobiographical or biographical accounts of how particular inventions (e.g.,Structured Modeling) were made. These could include personal experiences inearly development of OR/MS and an overview of what has happened since.• Development of OR/MS mathematical tools (e.g., stochastic programming, optimizationtheory).• Development of OR/MS in a particular industry sector such as global supplychain management.• Modeling systems for OR/MS and their development over time as well as speculationon future development (e.g., LINDO, LINGO, and What’sBest!)• New applications of OR/MS models (e.g., happiness)The target audience of this book is young researchers, graduate/advanced undergraduatestudents from OR/MS and related fields likecomputer science, engineering,and management as well as practitioners who want to understand how OR/MSmodeling came about over the past few decades and what research topics or modelingapproaches they could pursue in research or application.

Product proliferation has become a common phenomenon. Most companies now offer hundreds, if not thousands, of stock keeping units (SKUs) in order to compete in the market place. Companies with expanding product and service varieties face with problems of obtaining accurate demand forecasts, controlling production and inventory costs, and providing high quality and good delivery performance for the customers. Marketing managers often advocate widening product lines for increasing revenue and market share. However, the breadth of product line can also decrease the efficiency of manufacturing processes and distribution systems. Thus firms must weigh the benefits of product variety against its cost in order to determine the optimal level of product variety to offer to their customers. Academics and practitioners are interested in several fundamental questions about product variety. For instance, why do companies extend their product lines? Do consumers care about product variety? Will a brand with more variety enjoy higher market share? How should product variety be measured? How can a company exploit its product and process design to deliver a higher level of product variety quickly and cheaply? What should the level of product variety be and what should the price of each of the product variants be? What kind of 'challenges would a company face in offering a high level of product variety and how can these obstacles be overcome? The solutions to these questions span multiple functions and disciplines.

“Supply Chain Risk Management is an issue that many companies face and yet few companies know how to deal with it in a systematic and pragmatic manner. While avoiding and reducing supply chain risks are certainly preferable, developing ways to restore and stabilize supply chain operations rapidly after a major disruption is critical for managing global supply chains. Sodhi and Tang present important concepts, frameworks, strategies, and analyses that are essential for managing supply chain risks. Not only does this book suggest some practical ways to work with different partners to manage the risks that are present in a global supply chain, it creates a framework that would enable practitioners to engage researchers to work on this important area.”—Thomas A. Debrowski, Executive Vice President, Worldwide Operations, Mattel, Inc.“When a firm outsources its operations to external suppliers, the firm is vulnerable to major and rare disruptions that can occur at any link in the global supply chain. Because these disruptions rarely occur, few firms take commensurable actions to identify, assess, mitigate and respond to various types of supply chain risks. By introducing frameworks and concepts along with several case studies and a review of academic literature, Sodhi and Tang treat this important subject with practical relevance and academic rigor. This book will bring practitioners and researchers to develop effective and efficient ways to manage supply chain risks.”—Marshall L. Fisher, UPS Professor, Professor of Operations and Information Management and Co-Director of Fishman-Davidson Center for Service and Operations Management, The Wharton School, University of Pennsylvania“This book ties observations in practice to methodologies and research. The rich case examples motivated the approaches and methodologies used to mitigate risks, and in the course of doing so, Sodhi and Tang providedinsights on existing and new research opportunities. As a result, this book is highly relevant to both practitioners and academics. Also, the book is also written with management lessons on how risks can be mitigated, and how risks can be contained once disruptions have occurred. As such, it is also a book for management to gain insights and to develop management skills.”—Hau L. Lee, Thoma Professor of Operations, Information and Technology and Director of the Stanford Global Supply Chain Management Forum, Graduate School of Business, Stanford University“As companies have extended their supply chains globally and as the face increasing resource issues, they face a number of new risk challenges. While there are various case studies written about supply chain risks, this book gives a comprehensive treatment of the subject with clarity. The concepts and frameworks developed by Sodhi and Tang in this book would create awareness of this important and yet not well understood subject, and strategies described in this book would stimulate practitioners to develop a holistic approach for identifying, assessing, mitigating, and responding to different types of supply chain risks.”—Nick Wildgoose, Global Supply Chain Proposition Manager, Zurich Insurance​

This book focuses on three essential elements of agricultural supply chains: Planting and Growing, Processing and Selling, and Government Interventions. For decades, most agricultural economists applied macro-economic theory in decisions pertaining to the optimization of food production and distribution. However, few researchers used micro-economic theory to examine how individual farmers respond to market information, incentive pricing mechanisms and different market structures in the trade of agricultural goods. Examining challenges in agricultural supply chain operations through the lens of micro-economic theory is imperative because it can enable policymakers and social enterprises to develop and design market information provision policy, incentive contracts and market structures for improving farmer and consumer welfare.In each chapter, contributing authors motivate their research questions by providing the context and articulating the importance of their questions.They present their analysis to examine the respective research questions and explain their results. At the end of each chapter, they provide a short list of future research questions.

As public awareness of social and environmental issues grew, more consumers began to support firms committed to developing and operating environmentally sustainable and socially responsible supply chains.

As public awareness of social and environmental issues grew, more consumers began to support firms committed to developing and operating environmentally sustainable and socially responsible supply chains. Consumers, investors, and regulators began demanding transparency and accountability, pushing companies to address the environmental footprint of their products and operations. The book addresses essential questions, such as how a firm shifts its focus from being profit-focused to being triple-bottom-line driven and how a firm develops its supply chain with a conscience. Written by practice leaders and leading scholars, it sheds light on different paths a firm can take to embrace its role as a sustainability champion, paving the way for a future where profit and the planet coexist.The book is intended as a tribute to Professor Hau Lee’s seminal contributions, elevating the triple bottom line to the forefront of the Operations Management (OM) research agenda. It stimulates practitioners and researchers to engage in deeper and broader discussions about ways to strike a better balance among profit, people, and the planet.

Sharing accurate and timely supply and demand information throughout a supply chain can yield significant performance improvements to all members of the supply chain. Despite the benefits, many firms are reluctant to share information with their supply chain partners due to an unequal distribution of risks, costs, and benefits among the partners. Thus, incentive mechanisms must be in place to induce communication, cooperation, and collaboration among all members of a supply chain.  The issue of Information exchange/sharing has been examined by various researchers over the last 15-20 years. However, there is no research book that compiles various approaches, analyses, key implications, as well as future development of this area. This book will serve as a handbook for researchers who are interested in learning the state of the art of the line of research in this area and explore open research topics in this area.  Contributors, all leading researchers, have committed to delivering 18 chapters, broken into four distinct sections covering the Value of Information Sharing, Contracting and Information, Information Signaling, and Incentives for Information Sharing.
