Available in PDF, EPUB and Kindle. Book excerpt: An increasing interest to scheduling theory can be attributed to the high level of automation of all branches of human activity. The quality of modern production essentially depends on the planning decisions taken at different stages of a production process. Moreover, while the quality of these decisions is improving, the time and flexibility requirements for decision-making are becoming more important. All this stimulates scheduling research. Started as an independent discipline in the early fifties, it now has become an important branch of operations research. In the eighties, the largest Russian publishing house for scientific literature Nauka Publishers, Moscow, issued two books by a group of Byelorussian mathematicians: Scheduling Theory. Single-Stage Systems by V. S. Tanaev, V. S. Gordon and Y. M. Shafransky (1984) and Scheduling Theory. Multi-Stage Systems by V. S. Tanaev, Y. N. Sotskov and V. A. Strusevich (1989). Originally published in Russian, these two books cover two different major problem areas of scheduling theory and can be considered as a two-volume monograph that provides a systematic and comprehensive exposition of the subject. The authors are grateful to Kluwer Academic Publishers for creating the opportunity to publish the English translations of these two books. We are indebted to M. Hazewinkel, J. K. Lenstra, A. H. G. Rinnooy Kan, D. B. Shmoys and W. Szwarc for their supporting the idea of translating the books into English.
Download or read book Worst case Performance of Scheduling Heuristics written by Bo Chen and published by I.B.D. Limited. This book was released on 1994 with total page 156 pages. 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 A neutrosophic set based TLBO algorithm for the flexible job shop scheduling problem with routing flexibility and uncertain processing times written by Liangliang Jin and published by Infinite Study. 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.

Download or read book On the Solvability of Open Shop Scheduling Problems written by Urmila Pyakurel and published by LAP Lambert Academic Publishing. This book was released on 2011-09 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of scheduling n jobs each of which must be processed by m machines with shop dependent processing order is examined. If the order in which a given job is processed on the machine is not fixed, the system is called an open shop. This situation might occur in testing components of an automobile. The computational difficulty of solving most open shop problem is known with the majority being NP- hard. In shop scheduling problem, a combination of machine order and job order is represented by a shop graph or by the corresponding rank matrix pair (MO, JO). A task is to determine an optimal feasible sequence. Various models of mathematics have been presented to solve different shop scheduling problems. Here, the disjunctive graph model, block matrices model without preemption and with preemption and linear programming models are studied. Some problems have also been represented by Gantt charts. Polynomial time algorithms have been presented with complexity analysis. Some NP- hard problems are also discussed in both cases with preemption and without preemption.

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.

This book was released on 1991 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this thesis is the minimization of the sum of absolute deviations of job completion times from a common due date for the two machine flow shop scheduling problem (2SADD). The problem is mathematically formulated as a mixed integer program. The purpose of this research is the development of heuristic procedures to solve the 2SADD scheduling problem. The heuristic procedures provide a sequence which is solved for the optimal schedule using linear programming. The solutions of the heuristic procedures are compared against the optimal solutions for data sets with five and six jobs. The three best performing heuristic procedures are compared against each other using data sets with ten, fifteen, and twenty jobs. The recommendations of this research are to 1) use the optimal solution for the special case of a distant due date (greater than the sum of all processing times), 2) use Bagchi/Pairwise Interchange Heuristic for small numbers of jobs (less than ten), 3) use One-By-One/SPT and One-By-One/LPT for a number of jobs of ten or greater.
