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).

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 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).

This book was released on with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different with the plain flexible job-shop scheduling problem (FJSP), the FJSP with routing flexibility is more complex and it can be deemed as the integrated process planning and (job shop) scheduling (IPPS) problem, where the process planning and the job shop scheduling two important functions are considered as a whole and optimized simultaneously to utilize the flexibility in a flexible manufacturing system. Although, many novel meta-heuristics have been introduced to address this problem and corresponding fruitful results have been observed; the dilemma in real-life applications of resultant scheduling schemes stems from the uncertainty or the nondeterminacy in processing times, since the uncertainty in processing times will disturb the predefined scheduling scheme by influencing unfinished operations. As a result, the performance of the manufacturing system will also be deteriorated. Nevertheless, research on such issue has seldom been considered before. This research focuses on the modeling and optimization method of the IPPS problem with uncertain processing times. The neutrosophic set is first introduced to model uncertain processing times. Due to the complexity in the math model, we developed an improved teaching-learning-based optimization(TLBO) algorithm to capture more robust scheduling schemes.

This book was released on 1998 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We propose asymptotically optimal algorithms for the job shop scheduling and packet routing problems. We propose a relaxation for the job shop scheduling problem called the fluid control problem, in which we replace discrete jobs with the flow of a continuous fluid. The optimal solution of the fluid control problem can be computed in closed form and provides a lower bound C[subscript max] to the job shop scheduling problem. We use the optimal solution of the fluid control problem to construct a feasible schedule with objective value at most C[subscript max] + O([square root of (C[subscript max])]. For the packet routing problem with fixed paths the previous algorithm applies directly. For the general packet routing problem we propose a linear programming relaxation that provides a lower bound C[subscript max], and an algorithm that uses the optimal solution of the relaxation with objective value at most C[subscript max] + O([square root of (C[subscript max])]. This implies that as the total number of jobs (packets) tends to infinity, the proposed algorithms are asymptotically optimal. Unlike asymptotically optimal algorithms that rely on probabilistic assumptions, our proposed algorithms make no probabilistic assumptions, and they are asymptotically optimal for all instances with a large number of jobs (packets)."

Download or read book Metaheuristics for Production Systems written by El-Ghazali Talbi and published by Springer. This book was released on 2015-11-26 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the main techniques and newest trends to manage and optimize the production and service systems. The book begins by examining the three main levels of decision systems in production: the long term (strategic), the middle term (tactical) and short term (operational). It also considers online management as a new level (a sub level of the short term). As each level encounters specific problems, appropriate approaches to deal with these are introduced and explained. These problems include the line design, the line balancing optimization, the physical layout of the production or service system, the forecasting optimization, the inventory management, the scheduling etc. Metaheuristics for Production Systems then explores logistic optimization from two different perspectives: internal (production management), addressing issues of scheduling, layout and line designs, and external (supply chain management) focusing on transportation optimization, supply chain evaluation, and location of production. The book also looks at NP-hard problems that are common in production management. These complex configurations may mean that optimal solutions may not be reached due to variables, but the authors help provide a good solution for such problems. The effective new results and solutions offered in this book should appeal to researchers, managers, and engineers in the production and service industries.
