Available in PDF, EPUB and Kindle. Book excerpt: The research reported investigates the use of heuristics for selecting from several alternate routes, resulting from partially-ordered tasks in a job-shop order file. The experimental vehicle employed was digital simulation on the Project MAC Compatible Time-Sharing System. The methodology was to conduct two passes of simulated shop runs. The first, with two artificially high levels of alternate incidence, tested the efficiency of five different alternate routing heuristics in reducing mean tardiness. The second pass consisted of runs with the best heuristic developed during the first experimental phase, applied to a realistic length and frequency of alternate strings. The performance characteristics of the different heuristics are discussed at length. In addition, some implications are drawn of the computational nature of alternate routing and the difficulties encountered in implementing alternate routing heuristics at operation time. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The ability of a production system to complete orders on time is a critical measure of customer service. While there is typically a preferred routing for a job through the processing machines, often an alternative route is available that can be used to avoid bottleneck operations and improve due date performance. In this paper a heuristic approach is given to dynamically select routing alternatives for a set of jobs to be processed in a job shop. The approach is coupled with a job shop scheduling algorithm developed by Hodgson et al. (1998, 2000) to minimize the latest job (Lmax).

Download or read book POPULATION BASED SEARCH HEURISTICS FOR SCHEDULING JOB SHOPS ASSOCIATED WITH MULTIPLE ROUTINGS written by B. S. Girish and published by B. S. Girish. This book was released on 2024-01-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses two different models of job shop scheduling applications that are associated with multiple routings. The first application is the well known scheduling model, generally addressed in the literature as Flexible job shop scheduling problem (FJSP), which belongs to the category of toughest NP-hard problems. The second scheduling model addressed in this thesis is based on the production environment of a capital goods industry in which the components of different products are processed and assembled in an assembly job shop type environment. The processing operations on all components in the model also consider alternative routing option. This problem is, therefore, addressed as assembly job shop scheduling associated with multiple routings (AJSP), which is much more complex than FJSP. To solve such NP-hard problems, heuristic approaches have emerged as a promising alternative to the mathematical approaches. Three population based search heuristics, a Genetic Algorithm (GA), an Ant Colony Optimization (ACO) algorithm and a Particle Swarm Optimization (PSO) algorithm, are proposed to evolve optimal schedules for both the models. The performance of the three population based search heuristics for FJSP are tested with various benchmark instances for minimum makespan time criterion and evaluated by comparing their solutions with the lower bound solution (LB), best known solution (BKS) and the solution obtained with constraint programming formulation (CPF) for the problem solved using ILOG Solver. The performance comparison reveals that the proposed algorithms outperformed CPF and are competent with the existing approaches. The proposed algorithms are, therefore, effective tools for solving FJSP instances. The performance of the three population-based search heuristics for AJSP are tested with various problem instances for minimum total tardiness cost criterion and the results obtained are compared with the results of CPF solved using ILOG Solver. The performance comparison reveals that the proposed heuristics perform better than the CPF.

Available in PDF, EPUB and Kindle. Book excerpt: The contents of this book are based on invited papers submittedfor presentation and discussion at the 1990 Material Handling Research Colloquium held in Hebron, Kentucky, June 19-21,1990. The Colloquium was sponsored and organized by the College Industry Councilfor Material Handling Education (CIC-MHE) with addi tional co-sponsorship and funding provided by numerous organizations (see ac knowledgements). The purpose of the Colloquium was to foster open discussion about the current state of material handling research at universitiesfrom across the United States and Canada. It was an opportunity to share specific research directions and accomplishments. But more importantly, it was an opportunity to discuss the implications of the basic constraints to solving industry relevant problems in the field of material handling and closely related activities; the efficacy of the approaches being taken at the present time; and the directions believed to be of most value to the industry and to advancing the knowledge and science base of the material handling engineering discipline. The sponsoring organization, the College Industry Council for Material Handling Education was founded in 1952. The council is composed of college and university educators, material handling equipment manufacturers, distributors, users and consultants, representatives of the business press plus professional staff and members of other organizations concerned with material handling education.

Download or read book Heuristics Metaheuristics and Approximate Methods in Planning and Scheduling written by Ghaith Rabadi and published by Springer. This book was released on 2016-01-27 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this book is limited to heuristics, metaheuristics, and approximate methods and algorithms as applied to planning and scheduling problems. While it is not possible to give a comprehensive treatment of this topic in one book, the aim of this work is to provide the reader with a diverse set of planning and scheduling problems and different heuristic approaches to solve them. The problems range from traditional single stage and parallel machine problems to more modern settings such as robotic cells and flexible job shop networks. Furthermore, some chapters deal with deterministic problems while some others treat stochastic versions of the problems. Unlike most of the literature that deals with planning and scheduling problems in the manufacturing and production environments, in this book the environments were extended to nontraditional applications such as spatial scheduling (optimizing space over time), runway scheduling, and surgical scheduling. The solution methods used in the different chapters of the book also spread from well-established heuristics and metaheuristics such as Genetic Algorithms and Ant Colony Optimization to more recent ones such as Meta-RaPS.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with extensive information on path planning optimization for both single and multiple Autonomous Guided Vehicles (AGVs), and discusses practical issues involved in advanced industrial applications of AGVs. After discussing previously published research in the field and highlighting the current gaps, it introduces new models developed by the authors with the goal of reducing costs and increasing productivity and effectiveness in the manufacturing industry. The new models address the increasing complexity of manufacturing networks, due for example to the adoption of flexible manufacturing systems that involve automated material handling systems, robots, numerically controlled machine tools, and automated inspection stations, while also considering the uncertainty and stochastic nature of automated equipment such as AGVs. The book discusses and provides solutions to important issues concerning the use of AGVs in the manufacturing industry, including material flow optimization with AGVs, programming manufacturing systems equipped with AGVs, reliability models, the reliability of AGVs, routing under uncertainty, and risks involved in AGV-based transportation. The clear style and straightforward descriptions of problems and their solutions make the book an excellent resource for graduate students. Moreover, thanks to its practice-oriented approach, the novelty of the findings and the contemporary topic it reports on, the book offers new stimulus for researchers and practitioners in the broad field of production engineering.
