Available in PDF, EPUB and Kindle. Book excerpt: This report describes an approximation method for solving the minimum makespan problem of job shop scheduling. It sequences the machines one by one, successively, taking each time the machine identified as a bottleneck among the machines not yet sequenced. Every time after a new machine is sequenced, all previously established sequences are locally reoptimized. Both the bottleneck identification and the local reoptimization procedures are based on repeatedly solving certain one-machine scheduling problems. Besides this straight version of the Shifting Bottleneck Procedure, we have also implemented a version that applies the procedure to the nodes of a truncated search tree. Computational testing shows that our approach yields consistently better results than other procedures discussed in the literature. A high point of our computational testing occurred when the enumerative version of the Shifting Bottleneck Procedure found in a little over five minutes an optimal schedule to a notorious ten machines/ten jobs problem on which many algorithms have been run for hours without finding an optimal solution. Keywords: Heuristics.

Available in PDF, EPUB and Kindle. Book excerpt: Meta-heuristics have developed dramatically since their inception in the early 1980s. They have had widespread success in attacking a variety of practical and difficult combinatorial optimization problems. These families of approaches include, but are not limited to greedy random adaptive search procedures, genetic algorithms, problem-space search, neural networks, simulated annealing, tabu search, threshold algorithms, and their hybrids. They incorporate concepts based on biological evolution, intelligent problem solving, mathematical and physical sciences, nervous systems, and statistical mechanics. Since the 1980s, a great deal of effort has been invested in the field of combinatorial optimization theory in which heuristic algorithms have become an important area of research and applications. This volume is drawn from the first conference on Meta-Heuristics and contains 41 papers on the state-of-the-art in heuristic theory and applications. The book treats the following meta-heuristics and applications: Genetic Algorithms, Simulated Annealing, Tabu Search, Networks & Graphs, Scheduling and Control, TSP, and Vehicle Routing Problems. It represents research from the fields of Operations Research, Management Science, Artificial Intelligence and Computer Science.
Download or read book A Modified Shifting Bottleneck Approach to Job Shop Scheduling with Sequence Dependent Setups MSBSS written by Xiaoqing Sun and published by . This book was released on 1997 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research addresses the NP-Hard, practical problem of scheduling jobs with release dates, due dates and sequence dependent setups where the scheduling objective is to minimize the weighted sum of squared tardiness. Such a problem is practically relevant due to the fact that there are numerous industrial settings that involve sequence dependent setups. A shifting bottleneck based method (MSBSS) is developed for job shop scheduling with sequence dependent setups, which balances both efficiency and optimality. As a key component of MSBSS, a Lagrangian relaxation based approach (LRSSS) is also developed for single-machine scheduling with sequence dependent setups. Sequence dependent setups are formulated into capacity constraints, then the capacity constraints are relaxed using a Lagrangian multiplier. The primal problem is decomposed into job-level subproblems which are solved optimally and an approximation dual problem is then solved using a sub-gradient technique. The result of the relaxation is a list of jobs sequenced by beginning times that is then improved via a three-way enumeration. Experimental results are compared with EDD (earliest due date), ATCS (apparent tardiness cost with sequence dependent setups), dispatching rules, a 4-way enumeration local search, tabu search, and simulated annealing. The LRSSS approach results in superior solution quality with respect to EDD, ATCS, 4-way enumeration and tabu search results. It has comparable solution quality to the simulated annealing results, but is substantially more efficient. The LRSSS is then extended to job shop scheduling with sequence dependent setups, due dates and release dates. The resulting MSBSS procedure decomposes the job shop scheduling problem into a series of single-machine scheduling problems. Machines are scheduled in order of criticality defined as the marginal contribution of a machine to the objective function. The MSBSS approach is compared with EDD, ATCS, and SIMSET (similar setup times) dispatching rules. The MSBSS approach results in superior solution quality to the results of other dispatching rules. Overall the research has resulted in two efficient scheduling procedures (LRSSS and MSBSS) that fill an important gap in algorithm design dealing with practical, realistically sized scheduling problems.

This book was released on 2012-12-06 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finding exact solutions to many combinatorial optimization problems in busi ness, engineering, and science still poses a real challenge, despite the impact of recent advances in mathematical programming and computer technology. New fields of applications, such as computational biology, electronic commerce, and supply chain management, bring new challenges and needs for algorithms and optimization techniques. Metaheuristics are master procedures that guide and modify the operations of subordinate heuristics, to produce improved approx imate solutions to hard optimization problems with respect to more simple algorithms. They also provide fast and robust tools, producing high-quality solutions in reasonable computation times. The field of metaheuristics has been fast evolving in recent years. Tech niques such as simulated annealing, tabu search, genetic algorithms, scatter search, greedy randomized adaptive search, variable neighborhood search, ant systems, and their hybrids are currently among the most efficient and robust optimization strategies to find high-quality solutions to many real-life optimiza tion problems. A very large nmnber of successful applications of metaheuristics are reported in the literature and spread throughout many books, journals, and conference proceedings. A series of international conferences entirely devoted to the theory, applications, and computational developments in metaheuristics has been attracting an increasing number of participants, from universities and the industry.

Available in PDF, EPUB and Kindle. Book excerpt: In the foreword to Supply Chain Structures, Professor Paul Zipkin notes three global changes that have enabled the recent vast developments in the field of supply chains. Moreover, these changes may be only the beginning and more change is likely in the fast-moving field of supply chain management. These global changes are: the explosive growth of the Internet; the growth in free-market economies with the corresponding political interest in global economic stability; and the emergence of a global managerial culture focused on performance, quality, and service. Professor Zipkin goes on to say "In Supply Chain Structures, the editors Jeannette Song and David Yao have collected a spectrum of approaches to these challenges from some of the leading scholars of supply chains, from both the academic and commercial worlds. Each of the articles offers an interesting and illuminating way to think about the key issues in supply chain management. Some also offer practical techniques to solve important problems. Together they provide an excellent survey of the current state of the art in research and practice."

Book excerpt: With collaborative product development in a geographically distributed environment and global outsourcing becoming normal for many companies, it is imperative to bring academics, researchers and industrialists together to share research ideas and best practice. The European-Asia Symposium on Engineering Design and Manufacture (EASED 2004) provides such a platform and aims to increase the exchange of ideas and best practice among practitioners and researchers from two major global regions - Europe and Asia. As the manufacturing activities, associated with the design activities in European, American and Japan, are being transferred to Asia, it is timely to organise this International Symposium. The Symposium brings together research experts and industrialists to focus on the issues related to these global changes. This geographical distribution of tasks involved in the whole engineering product realisation process brings great challenge as well as huge benefits. This Symposium provides a platform for academic researchers and industrial practitioners to exchange ideas used to address the challenges presented by this new global economic development. This book presents 75 papers from 185 accepted refereed papers presented at EASED2004.

This book was released on 2013-12-02 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Preface: This festschrift is devoted to recognize the career of a man who not only witnessed the growth of operations research from its inception, but also contributed significantly to this growth. Dr. Salah E. Elmaghraby received his doctorate degree from Cornell University in 1958, and since then, his scholarly contributions have enriched the fields of production planning and scheduling and project scheduling. This collection of papers is contributed in his honor by his students, colleagues, and acquaintances. It offers a tribute to the inspiration received from his work, and from his guidance and advice over the years, and recognizes the legacy of his many contributions. Dr. Elmaghraby is a pioneer in the area of project scheduling (in particular, project planning and control through network models, for which he coined the term ‘activity networks’.) In his initial work in this area, he developed an algebra based on signal flow graphs and semi-Markov processes for analyzing generalized activity networks involving activities with probabilistic durations. This work led to the development of what was later known as the Graphical Evaluation and Review Technique (GERT), and GERT simulation models. He has made fundamental contributions in determining criticality indices for activities, in developing methodologies for project compression and time/cost analysis, and in the use of stochastic and chance-constrained programming and Petri Nets for the analysis of activity networks. This volume brings together fourteen contributions, which can be viewed under the following three main themes: operations research and its application in production planning; project scheduling, and production scheduling, inspired by, and in many cases based on, Dr. Elmaghraby’s work in these areas. The first five chapters are devoted to the first theme, followed by four chapters each devoted to the other two, respectively. An additional chapter is devoted to the vulnerability of multimodal freight systems.
