This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An open-shop scheduling problem to minimize the total weighted earliness-tardiness of job-on-machine operations is studied. Each operation has its own due date, earliness weight and tardiness weight. An efficient relax-and-solve heuristic is developed. A feature that makes the proposed heuristic distinctive from the existing heuristics of this kind is that it operates by iterative relaxation and optimization of a series of sub-problems. Performance of the proposed heuristic is verified on a set of 72 benchmark instances with up to 200 operations, adapted from the literature on a similar job-shop scheduling problem. The heuristic delivers best solutions for nearly 71 % of the instances (i.e., 51 out of 72 instances), including the best solution for all instances with 150 and 200 operations. Its running time is around three minutes, while CLPEX was run for 30 minutes.

Available in PDF, EPUB and Kindle. Book excerpt: This title presents a large variety of models and algorithms dedicated to the resource-constrained project scheduling problem (RCPSP), which aims at scheduling at minimal duration a set of activities subject to precedence constraints and limited resource availabilities. In the first part, the standard variant of RCPSP is presented and analyzed as a combinatorial optimization problem. Constraint programming and integer linear programming formulations are given. Relaxations based on these formulations and also on related scheduling problems are presented. Exact methods and heuristics are surveyed. Computational experiments, aiming at providing an empirical insight on the difficulty of the problem, are provided. The second part of the book focuses on several other variants of the RCPSP and on their solution methods. Each variant takes account of real-life characteristics which are not considered in the standard version, such as possible interruptions of activities, production and consumption of resources, cost-based approaches and uncertainty considerations. The last part presents industrial case studies where the RCPSP plays a central part. Applications are presented in various domains such as assembly shop and rolling ingots production scheduling, project management in information technology companies and instruction scheduling for VLIW processor architectures.

Available in PDF, EPUB and Kindle. Book excerpt: Jens Kuhpfahl analyzes the job shop scheduling problem with minimizing the total weighted tardiness as objective. First, he provides a suitable graph representation based on a disjunctive graph formulation. Second, several key components of local search procedures are analyzed and enhanced. The resulting outputs of these investigations contribute to the development of a new solution procedure whose performance quality leads to superior computational results.

Available in PDF, EPUB and Kindle. Book excerpt: "Attempts to cope with the challenge of optimal utilization of limited resources in accomplishing variegated tasks have resulted in an exciting field known as scheduling theory. The resources and tasks are commonly referred to as machines and jobs, respectively. In this thesis efficient heuristic algorithms are developed, which quickly provide near optimal solutions for various problems in scheduling theory that are practically intractable to solve to optimality. The worst-case performance of the heuristic algorithms is thoroughly analyzed. With respect to machine environments, the scheduling problems considered range from parallel machine shops, through open and flow shops, to common generalizations of the classical shop models. With respect to the job characteristics, these problems may involve preemptive or non-preemptive scheduling, with setup times included in or separated from processing times. With respect to the ways jobs are released and scheduled, both off-line and on-line problems are investigated."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Earliness Tardiness Scheduling Problems II written by Nicholas G. Hall and published by . This book was released on 2017 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: A companion paper (Part I) considers the problem of minimizing the weighted earliness and tardiness of jobs scheduled on a single machine around a common due date, d, which is unrestrictively late. This paper (Part II) considers the problem of minimizing the unweighted earliness and tardiness of jobs, allowing the possibility that d is early enough to constrain the scheduling decision. We describe several optimality conditions. The recognition version of the problem is shown to be NP-complete in the ordinary sense, confirming a well known conjecture. Moreover, this complexity definition is precise, since we describe a dynamic programming algorithm which runs in pseudopolynomial time. This algorithm is also extremely efficient computationally, providing an improvement over earlier procedures, of almost two orders of magnitude in the size of instance that can be solved. Finally, we describe a special case of the problem which is polynomially solvable.

Download or read book Minimization of Weighted Tardiness in Job Shops Using Shifting Bottleneck and Tabu Search Procedures written by Srinivasa Rao Bongarala and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scheduling to meet set due dates is one of the most critical issues in modern production systems. One measure of schedule effectiveness in the presence of due dates is weighted tardiness since it can capture the cost of contractual penalties and other losses to an organization. This research work concentrates on the problem of minimizing the total weighted tardiness in classical job shops. Job shop scheduling problems are among the hardest known combinatorial optimization problems. In particular the problem of minimizing tardiness in job shops is strongly NP-hard, which makes finding optimal solutions to it impractical in most realistic situations. We approach this problem using two well known heuristics, namely the shifting bottleneck procedure and tabu search. Both heuristics are known to perform very well for minimizing makespan in job shops. Here we adapt them for the objective of minimizing weighted tardiness and test both under different parameter settings in order to select implementations that give the best results for a given computational effort. We test our algorithms with problem instances taken from the literature and with randomly generated instances. We present our observations and conclusions regarding the relative performance of these heuristics and their performance in comparison with dispatching rules. In particular, we find that the shifting bottleneck procedure outperforms tabu search for this problem.

Available in PDF, EPUB and Kindle. Book excerpt: Scheduling theory is an important branch of operations research. Problems studied within the framework of that theory have numerous applications in various fields of human activity. As an independent discipline scheduling theory appeared in the middle of the fifties, and has attracted the attention of researchers in many countries. In the Soviet Union, research in this direction has been mainly related to production scheduling, especially to the development of automated systems for production control. In 1975 Nauka ("Science") Publishers, Moscow, issued two books providing systematic descriptions of scheduling theory. The first one was the Russian translation of the classical book Theory of Scheduling by American mathematicians R. W. Conway, W. L. Maxwell and L. W. Miller. The other one was the book Introduction to Scheduling Theory by Soviet mathematicians V. S. Tanaev and V. V. Shkurba. These books well complement each other. Both. books well represent major results known by that time, contain an exhaustive bibliography on the subject. Thus, the books, as well as the Russian translation of Computer and Job-Shop Scheduling Theory edited by E. G. Coffman, Jr., (Nauka, 1984) have contributed to the development of scheduling theory in the Soviet Union. Many different models, the large number of new results make it difficult for the researchers who work in related fields to follow the fast development of scheduling theory and to master new methods and approaches quickly.
