Book excerpt: In this paper, we study the rescheduling problem of a two-tier supply chain after major supply disruptions. In our model, a service provider provides maintenance job requests to its customers. The replacement parts that are used in the maintenance requests are provided by a designated manufacturer. After major production disruption hits, the service provider needs to reschedule all jobs to minimize related costs. We formulate the job rescheduling problem for a coordinated supply chain as an integer program to minimize the tardiness and the channel's total inventory cost. An extension of the main model with revised processing time is also discussed. A two-stage genetic algorithm is proposed to solve this integer program. We tested this algorithm on a dataset generated from a heavy machinery maintenance provider. Numerical results show that our model generates solutions that outperforms the original schedule. In addition, the proposed algorithm has better performance compared with other common genetic algorithms.

Download or read book Rescheduling Under Disruptions in Manufacturing Systems written by Dujuan Wang. This book was released on 2020-03-11. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to the models, methods, and results of some rescheduling problems in the presence of unexpected disruption events, including job unavailability, arrival of new jobs, and machine breakdown. The occurrence of these unexpected disruptions may cause a change in the planned schedule, which may render the originally feasible schedule infeasible. Rescheduling, which involves adjusting the original schedule to account for a disruption, is necessary in order to minimize the effects of the disruption on the performance of the system. This involves a trade-off between finding a cost-effective new schedule and avoiding excessive changes to the original schedule. This book views scheduling theory as practical theory, and it has made sure to emphasize the practical aspects of its topic coverage. Thus, this book considers some scenarios existing in most real-world environments, such as preventive machine maintenance, and deteriorating effect where the actual processing time of a job gets longer along with machine’s usage and age. To alleviate the effect of disruption events, some flexible strategies are adopted, including allocation extra resources to reduce job processing times or rejection the production of some jobs. For each considered scenario, depending on the model settings and on the disruption events, this book addresses the complexity, and the design of efficient exact or approximated algorithms. Especially when optimization methods and analytic tools fall short, this book stresses metaheuristics including improved elitist non-dominated sorting genetic algorithm and differential evolution algorithm. This book also provides extensive numerical studies to evaluate the performance of the proposed algorithms. The problem of rescheduling in the presence of unexpected disruption events is of great importance for the successful implementation of real-world scheduling systems. There is now an astounding body of knowledge in this field. This book is the first monograph on rescheduling. It aims at introducing the author's research achievements in rescheduling. It is written for researchers and Ph.D. students working in scheduling theory and other members of scientific community who are interested in recent scheduling models. Our goal is to enable the reader to know about some new achievements on this topic.

Book Synopsis Industries and Disasters by : Takahiro Fujimoto

Download or read book Industries and Disasters written by Takahiro Fujimoto. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to explore the ways that industries, under the pressures of global competition, balance sustained industrial competitiveness and robustness against major disasters. The book focuses mainly on the impact of disasters on supply chains for manufactured (mainly tradable) goods. A special feature of this particular theme is that companies have to deal with not only disasters that may come someday, but also global competition that industrial sites have to face every day. If, for example, companies add excessive amounts of inventory to their manufacturing sites for fear of the next major earthquake, they may not survive long enough to see the next earthquake due to their loss of global competitiveness. Thus, on a practical side, this book proposes that companies can balance global competitiveness and the anti-disaster robustness of industrial sites, rather than simply choosing one or the other, if they organize their efforts under the principles of continuous improvement (kaizen) and lean production. We have adopted a framework rooted in a design-based view of manufacturing for the empirical analysis and practical proposals of this book. That is, we argue that a manufacturing process can be defined broadly as the flow of value-carrying design information to customers. It follows that the key to the quick recovery of supply chains is to make the design informations stock and flow robust, visible, portable, recoverable, replicable, and restorable before and after disasters happen. Using these characteristics of information as a guide, companies need to build organizational capabilities for quickly recovering and/or moving the information assets embedded within the production processes that were damaged in a disaster. This book argues that such capabilities overlap to a large degree with the know-how and skills developed by kaizen activities. The empirical case studies contained in this book were conducted through extensive fieldwork at industrial sites mostly in Japan, which is known as one of the countries that is most vulnerable to natural disasters. Although the book mainly covers natural disasters (earthquakes, tsunamis, floods), there is also a chapter on a human-induced factory fire that had a major impact on Japans automotive supply chain. Based on the actual responses of Japanese companies (Toyota, Honda, Aisin Seiki, Epson, Renesas, and Riken, among others) to supply chain and production disruptions caused by major disasters, this book gives practical implications for firms that take a leading role in managing industrial supply chains. In particular, guidance is given on the ways in which supply chains can be diagnosed for vulnerabilities and the remedies that may be applied. One such countermeasure, virtual dualization, is explained in detail as a means for achieving both supply chain robustness and competitiveness for complex products that require intense coordination in their design and production. A common theme that runs throughout the chapter is the importance of building trust among the participants in a supply chain.

Book excerpt: This book investigates individual companies’ and industries’ supply chain risk management approaches to identify risk drivers and verify effective risk-reduction measures and business continuity plans. Typically, supply chain risk assessments focus on normative guidelines based on single best practice examples or vulnerability events, and there has been little work exploring how the concepts of supply chain risk management and resilience are related. However, since this relationship has implications for developing integrated response strategies, a clear understanding of the possible consequences is a fundamental step in building socio-economic resilience along the supply chain. Against this background, the book addresses three main topics: firstly, it defines the conceptual and sectoral domains of supply chain risk management and resilience by examining the welfare effects of extreme weather events and other economic shocks on selected global supply chains. It then presents an in-depth analysis of the scope of public–private partnerships to tackle the risks, by empirically exploring supply chain risk effects and information management. Thirdly, it proposes a regional cooperation framework in the context of major supply chain vulnerability events such as disasters and global financial crises.
