This paper studies multi-tier supply chain networks in the presence of disruption risk. Firms decide how to source their inputs from upstream suppliers so as to maximize their expected profits, and prices of intermediate goods are set so that markets clear. We provide an explicit characterization of equilibrium prices and profits, which allows us to derive insights on how the network structure, i.e., the number of firms in each tier, production costs, and disruption risk affect firms' profits. We discuss the prescriptive implications of our findings by exploring how a firm should prioritize among its suppliers (direct and indirect) when investing in improving their production reliability. Furthermore, we establish that networks that maximize profits for firms that operate in different stages of the production process, i.e., for the upstream supplier and the downstream retailer, are structurally different. In particular, the latter have relatively less diversified downstream tiers and generate more variable output than the former. Finally, we study the question of endogenous chain formation by considering a game of entry, i.e., firms decide whether to engage in production by forming beliefs about their profits in the post-entry supply chain. We argue that endogenous entry leads to chains that are inefficient in terms of the number of firms that engage in production.

One of the most critical issues facing supply chain managers in today’s globalized and highly uncertain business environments is how to deal proactively with disruptions that might affect the complicated supply networks characterizing modern enterprises. Supply Chain Disruptions: Theory and Practice of Managing Risk presents a state-of the-art perspective on this particular issue. Supply Chain Disruptions: Theory and Practice of Managing Risk demonstrates that effective management of supply disruptions necessitates both strategic and tactical measures – the former involving optimal design of supply networks; the latter involving inventory, finance and demand management. It shows that managers ought to use all available levers at their disposal throughout the supply network – like sourcing and pricing strategies, providing financial subsidies, encouraging information sharing and incentive alignment between supply chain partners – in order to tackle supply disruptions. The editors combine up-to-date academic research with the latest operational risk management practices used in industry to demonstrate how theoreticians and practitioners can learn from each other. As well as providing a wealth of knowledge for students and professors who are interested in pursuing research or teaching courses in the rapidly growing area of supply chain risk management, Supply Chain Disruptions: Theory and Practice of Managing Risk also acts as a ready reference for practitioners who are interested in understanding the theoretical underpinnings of effective supply disruption management techniques.

A fail-safe supply network is designed to mitigate the impact of variations and disruptions on people and corporations. This is achieved by (1) developing a network structure to mitigate the impact of disruptions that distort the network structure and (2) planning flow through the network to neutralize the effects of variations. In this monograph, we propose a framework, develop mathematical models and provide examples of fail-safe supply network design. We show that, contrary to current thinking as embodied in the supply network literature, disruption management decisions made at the strategic network design level are not independent from variation management decisions made at the operational level. Accordingly, we suggest that it is beneficial to manage disruptions and variations concurrently in supply networks. This is achieved by architecting fail-safe supply networks, which are characterized by the following elements: reliability, robustness, flexibility, structural controllability, and resilience. Organizations can use the framework presented in this monograph to manage variations and disruptions. Managers can select the best operational management strategies for their supply networks considering variations in supply and demand, and identify the best network restoration strategies including facility fortification, backup inventory, flexible production capacity, flexible inventory, and transportation route reconfiguration. The framework is generalizable to other complex engineered networks.

This book offers an introduction to the ripple effect in the supply chain for a broad audience comprising recent developments. The chapters of this handbook are written by leading experts in supply chain risk management and resilience. For the first time, the chapters present in their synergy a multiple-faceted view of the ripple effect in supply chains, while considering organization, optimization, and informatics perspectives. Ripple effect describes the impact of a disruption propagation on supply chain performance, structural designs and operational parameters. The ripple effect manifests when the impact of a disruption cannot be localized and cascades along the supply chain. The resulting structural dynamics can lead to capacity and demand fulfilment downscaling and negatively influence the firm’s financial and operational performance. The book delineates major features of the ripple effect and methodologies to mitigate the adverse impact of supply chain disruption propagation and to recover in case of severe disruptions. The book provides fresh insights for supply chain management and engineering regarding the following questions: - In what circumstance does one failure cause other failures? - Which structures of the supply chain are especially susceptible to the ripple effect? - What are the typical ripple effect scenarios and what are the most efficient ways to respond them? Distinctive Features: • It considers ripple effect in the supply chain from an multi-disciplinary perspective• It offers an introduction to ripple effect mitigation and recovery policies in the framework of disruption risk management in supply chains for a broad audience• It integrates management and engineering perspectives on disruption risk management in the supply chain• It presents innovative optimization and simulation models for real-life management problems• It considers examples from both industrial and service supply chains• It reveals decision-making recommendations for tackling disruption risks in the supply chain in proactive and reactive domains.

Managing Supply Chain Disruptions categorizes and review the substantive research contributions relating to managing supply chain disruptions. With a primary emphasis on formulating directions for future research, the authors focus on significant research and practical findings. Managing Supply Chain Disruptions reviews the general area of supply chain disruptions and examine classifications of disruptions which can be used to provide insights into the disruption management process. It reviews the literature in the emerging field of disruption risk management which attempts to identify specific risks associated with supply chain disruptions. This is followed by a review of conceptual/empirical research with a focus on providing general insights into how one or more organizations have managed the risk associated with disruptions. Given that designing robust supply chain networks are a key feature of managing disruption risk, the authors examine the relevant research in this domain. A detailed analysis of prior research targeted at managing specific risks (e.g., product, supply, operations/process, and transportation risks) is presented, and finally, directions for future research are discussed.

This book offers an introduction to structural dynamics, ripple effect and resilience in supply chain disruption risk management for larger audiences. In the management section, without relying heavily on mathematical derivations, the book offers state-of-the-art concepts and methods to tackle supply chain disruption risks and designing resilient supply chains in a simple, predictable format to make it easy to understand for students and professionals with both management and engineering background. In the technical section, the book constitutes structural dynamics control methods for supply chain management. Real-life problems are modelled and solved with the help of mathematical programming, discrete-event simulation, optimal control theory, and fuzzy logic. The book derives practical recommendations for management decision-making with disruption risk in the following areas: How to estimate the impact of possible disruptions on performance in the pro-active stage? How to generate efficient and effective stabilization and recovery policies? When does one failure trigger an adjacent set of failures? Which supply chain structures are particular sensitive to ripple effect? How to measure the disruption risks in the supply chain?

This dissertation studies the impact of different network structures and the structural positions of supply chain entities on their performance. The first essay focuses on the performance of buyers by examining the relationship between buyers' supply network structures and their performance. We use two network-level measures (network density and network centralization) as indicators of different supply network structures to study this relationship. We investigate how the interplay between network structure and firm performance differs in various industry settings. Our ego-centric network panel dataset from 2015 to 2018 included focal companies from three industries: automotive (n = 76), pharmaceutical (n = 66), and food & beverage (n = 105). Our results suggest that supply network structures have differential effects on buyer performance contingent upon industry context. We provide specific recommendations to focal companies' managers on what specific network structures would enhance their operational performance under various business environments.The second essay investigates what specific aspects of first-tier suppliers drive their performance. We consider two multi-factor efficiency measures: operational efficiency and structural efficiency. We investigate the direct effects of structural and operational efficiencies on first-tier supplier performance as well as the moderating role of structural efficiency in the relationship between operational efficiency and supplier performance. We test these relationships using a panel dataset of 278 observations obtained from 75 first-tier suppliers in the global automotive supply network over four years. Our findings demonstrate synergies between suppliers' internal resources and external relationships in enhancing their performance.Building on the first two essays, the third essay investigates the supply network structures that are robust to disruptions from the focal company's standpoint. By considering network density and network centralization, and modeling supply chain disruptions using simulations, we assess the impact of disruptions by investigating changes in the structural efficiency of the focal company. Our findings suggest that dense and decentralized supply networks are more robust to disruptions than sparse and centralized supply networks. We also find that this result becomes more evident as the magnitude of the disruption increases. Our findings have important implications for resource allocation and fortification strategies to design and operate robust and resilient networks.

Stories from Nokia, Dell, UPS, Toyota, and other companies show how firms can reduce their vulnerability to high-impact distributions, from earthquakes to strikes, from SARS to terrorism, and use them for competitive advantage. What happens when fire strikes the manufacturing plant of the sole supplier for the brake pressure valve used in every Toyota? When a hurricane shuts down production at a Unilever plant? When Dell and Apple chip manufacturers in Taiwan take weeks to recover from an earthquake? When the U.S. Pacific ports are shut down during the Christmas rush? When terrorists strike? In The Resilient Enterprise, Yossi Sheffi shows that companies' fortunes in the face of such business shocks depend more on choices made before the disruption than they do on actions taken in the midst of it—and that resilience benefits firms every day, disaster or no disaster. He shows how companies can build in flexibility throughout their supply chains, based on proven design principles and the right culture—balancing security, redundancy, and short-term profits. And he shows how investments in resilience and flexibility not only reduce risk but create a competitive advantage in the increasingly volatile marketplace.Sheffi describes the way companies can increase security—reducing the likelihood of a disruption—with layered defenses, the tracking and analysis of “near-misses,” fast detection, and close collaboration with government agencies, trading partners, and even competitors. But the focus of the book is on resilience—the ability to bounce back from disruptions and disasters—by building in redundancy and flexibility. For example, standardization, modular design, and collaborative relationships with suppliers (and other stakeholders) can help create a robust supply chain. And a corporate culture of flexibility—with distributed decision making and communications at all levels—can create a resilient enterprise.Sheffi provides tools for companies to reduce the vulnerability of the supply chain they live in. And along the way he tells the stories of dozens of enterprises, large and small, including Toyota, Nokia, General Motors, Zara, Land Rover, Chiquita, Aisin Seiki, Southwest Airlines, UPS, Johnson and Johnson, Intel, Amazon.com, the U.S. Navy, and others, from across the globe. Their successes, failures, preparations, and methods provide a rich set of lessons in preparing for and managing disruptions. Additional material available at www.TheResilientEnterprise.com.
