This book was released on 2013 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a disruption brings down one of company's manufacturing facilities, it can have a ripple effect on the entire supply chain and threaten the company's ability to compete. In this thesis, we develop an effective disruption mitigation strategy by using both process flexibility and strategic inventory. The model is focused on a manufacturer with multiple plants producing multiple products, where strategic inventory can be held for any product. We propose a new metric of supply chain robustness, defined as the maximum time that no customer demand is lost regardless of which plant is disrupted. Using this metric, we analyze K-chain flexibility designs in which each plant is capable of producing exactly K products. It is demonstrated that a 2-chain design, which is known to be effective for matching supply with demand when there is no disruption, is not robust when there is both disruption and demand uncertainty. However, it is shown that a 3-chain design is significantly more robust and achieves the same robustness as full flexibility under high uncertainty level. We then extend the model to an assembly system and find that investment in process flexibility designs changes the optimal inventory placements. In particular, when the degree of flexibility is high, more inventory is allocated to standard components, i.e. components used by multiple products, but when the degree of flexibility is low, more inventory is allocated to non-standard components.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study a hybrid strategy that uses both process flexibility and finished goods inventory for supply chain risk mitigation. The interplay between process flexibility and inventory is modeled as a two-stage robust optimization problem. In the first stage, the firm allocates inventory before disruption happens; in the second stage, after a disruption happens, the firm determines production quantities at each plant to minimize demand loss. Our robust optimization model can be solved efficiently using constraint generation, and under some stylized assumptions, can be solved in closed form. For a canonical family of flexibility designs known as the K-chains, our analysis shows that the optimal inventory decision critically depends on the degree of supply chain flexibility, and the widely studied 2-chain design may not be sufficient to mitigate supply risk. Moreover, the optimal inventory allocations vary significantly under different degrees of flexibility. These observations are verified through a numerical case study of an automobile supply chain.

Available in PDF, EPUB and Kindle. Book excerpt: Disruptive technologies have the power to upend supply chains, adding uncertainty, cost, and complexity to any business. These technologies can also create competitive advantage, but only if organizations strategically build them into their supply chains. Supply Chain Disruption, with a foreword by John Gattorna, provides the vital knowledge that supply chain managers need in order to implement disruptive technologies strategically. This essential book avoids a one-size-fits-all approach and encourages the reader to consider customer needs first before aligning appropriate technologies with each supply chain application. Supply Chain Disruption focuses on information systems, analysing how companies currently integrate and implement potentially disruptive technologies into their supply chain roadmaps. It presents new ways of planning more effectively and efficiently through the use of new tools and techniques, creating improvements in agility, customer service and cost.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Process flexibility has been a well-established supply chain strategy in both theory and practice that enhances responsiveness to demand uncertainty. In this study, we extend the scope of this strategy to supply disruption mitigation by analyzing a long chain system. Specifically, we investigate the effectiveness of long chains in the face of random supply disruption under ambiguous demand. Our study derives a closed-form, tight bound on the ratio of expected sales under supply disruption for the long chain relative to that of a fully flexible system. Our analysis provides a concrete analytical result demonstrating that the fraction of benefits a long chain can achieve relative to full flexibility increases in the disruption probability when supply designed capacity equals expected demand. Also, long chain demonstrates superior resilience by withstanding a non-negligible fraction of the supply disruption due to its relative sparse structure compared to a fully flexible system. To comprehensively handle supply disruption and demand ambiguity, we introduce a moment decomposition approach that easily adapts to general piecewise polynomial performance metrics, such as the type-I service level, which is a novel contribution in the existing literature. Our approach can also incorporate higher-moment information (such as skewness and kurtosis) on the random demand while maintaining tractability through a semidefinite program (SDP). To further demonstrate the strength of this approach, we apply it to study the capacity configuration problem. Our study reveals that, in the absence of supply disruption, attaining a specific service level requires a capacity level close to that of a fully flexible system, even when the demand distribution is only partially characterized. In contrast, a notable increase in capacity is required under supply disruption. Yet, long chain outperforms dedicated system significantly in capacity requirement. Our findings underscore the remarkable resilience demonstrated by long chains and the importance of adapting capacity configuration decisions to supply disruption.

This book was released on 2000-03-23 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The managed flow of goods and information from raw material to final sale also known as a "supply chain" affects everythingâ€"from the U.S. gross domestic product to where you can buy your jeans. The nature of a company's supply chain has a significant effect on its success or failureâ€"as in the success of Dell Computer's make-to-order system and the failure of General Motor's vertical integration during the 1998 United Auto Workers strike. Supply Chain Integration looks at this crucial component of business at a time when product design, manufacture, and delivery are changing radically and globally. This book explores the benefits of continuously improving the relationship between the firm, its suppliers, and its customers to ensure the highest added value. This book identifies the state-of-the-art developments that contribute to the success of vertical tiers of suppliers and relates these developments to the capabilities that small and medium-sized manufacturers must have to be viable participants in this system. Strategies for attaining these capabilities through manufacturing extension centers and other technical assistance providers at the national, state, and local level are suggested. This book identifies action steps for small and medium-sized manufacturersâ€"the "seed corn" of business start-up and developmentâ€"to improve supply chain management. The book examines supply chain models from consultant firms, universities, manufacturers, and associations. Topics include the roles of suppliers and other supply chain participants, the rise of outsourcing, the importance of information management, the natural tension between buyer and seller, sources of assistance to small and medium-sized firms, and a host of other issues. Supply Chain Integration will be of interest to industry policymakers, economists, researchers, business leaders, and forward-thinking executives.
Download or read book Demand Flexibility in Supply Chain Planning written by Joseph Geunes and published by Springer Science & Business Media. This book was released on 2012-02-17 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work encapsulates the essential developments in this field into a single resource, as well as to set an agenda for further development in the field. This brief focuses on the demand flexibility in supply chains with fragmented results distributed throughout the literature. These results have strong implications for managing real-world complex operations planning problems. This book exploits dimensions of demand flexibility in supply chains and characterizes the best fit between demand properties and operations capabilities and constraints. The origins and seminal works are traced in integrated demand and operations planning and an in-depth documentation is provided for the current state of the art. Systems with inherent costs and constraints that must respond to some set of demands at a minimum cost are examined. Crucial unanswered questions are explored and the high-value research directions are highlighted for both practice and for the development of new and interesting optimization models and algorithms.

Download or read book Dynamic Learning and Optimization for Operations Management Problems written by He Wang (Ph. D.) and published by . This book was released on 2016 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advances in information technology and the increased availability of data, new approaches that integrate learning and decision making have emerged in operations management. The learning-and-optimizing approaches can be used when the decision maker is faced with incomplete information in a dynamic environment. We first consider a network revenue management problem where a retailer aims to maximize revenue from multiple products with limited inventory constraints. The retailer does not know the exact demand distribution at each price and must learn the distribution from sales data. We propose a dynamic learning and pricing algorithm, which builds upon the Thompson sampling algorithm used for multi-armed bandit problems by incorporating inventory constraints. Our algorithm proves to have both strong theoretical performance guarantees as well as promising numerical performance results when compared to other algorithms developed for similar settings. We next consider a dynamic pricing problem for a single product where the demand curve is not known a priori. Motivated by business constraints that prevent sellers from conducting extensive price experimentation, we assume a model where the seller is allowed to make a bounded number of price changes during the selling period. We propose a pricing policy that incurs the smallest possible regret up to a constant factor. In addition to the theoretical results, we describe an implementation at Groupon, a large e-commerce marketplace for daily deals. The field study shows significant impact on revenue and bookings. Finally, we study a supply chain risk management problem. We propose a hybrid strategy that uses both process flexibility and inventory to mitigate risks. The interplay between process flexibility and inventory is modeled as a two-stage robust optimization problem: In the first stage, the firm allocates inventory, and in the second stage, after disruption strikes, the firm schedules its production using process flexibility to minimize demand shortage. By taking advantage of the structure of the second stage problem, we develop a delayed constraint generation algorithm that can efficiently solve the two-stage robust optimization problem. Our analysis of this model provides important insights regarding the impact of process flexibility on total inventory level and inventory allocation pattern.
