This book was released on 1997 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We consider the problem of scheduling a set of jobs on a single machine with the objective of mimizing weighted (average) completion time. The problem is NP-hard when there are precedence constraints between jobs, [12] and we provide a simple and efficient combinatorial 2-approximation algorithm. In contrast to our work, earlier approximation altorithms [9] achieving the same ratio are based on solving a linear programming relaxation of the problem.

Available in PDF, EPUB and Kindle. Book excerpt: We discuss the problem of sequencing precedence-constrained jobs on a single machine to minimize the average weighted completion time. This problem has attracted much attention in the mathematical programming community since Sidney's pioneering work in 1975. We look at the problem from a polyhedral perspective and uncover a relation between Sidney's decomposition theorem and different linear programming relaxations. More specifically, we present a generalization of Sidney's result, which particularly allows us to reason that virtually all known 2-approximation algorithms comply with his decomposition. Moreover, we establish a connection between the single-machine scheduling problem and the vertex cover problem. Indeed, in the special case of series-parallel precedence constraints, we prove that the sequencing problem can be seen as a special case of the vertex cover problem. We also argue that this result is true for general precedence constraints if one can show that a certain integer program represents a valid formulation of the sequencing problem. Finally, we give a 3/2-approximation algorithm for two-dimensional partial orders, and we also provide a characterization of the active inequalities of a linear programming relaxation in completion time variables.

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.

Available in PDF, EPUB and Kindle. Book excerpt: An up-to-date and comprehensive treatment of the fundamentals of scheduling theory, including recent advances and state-of-the-art topics Principles of Sequencing and Scheduling strikes a unique balance between theory and practice, providing an accessible introduction to the concepts, methods, and results of scheduling theory and its core topics. With real-world examples and up-to-date modeling techniques, the book equips readers with the basic knowledge needed for understanding scheduling theory and delving into its applications. The authors begin with an introduction and overview of sequencing and scheduling, including single-machine sequencing, optimization and heuristic solution methods, and models with earliness and tardiness penalties. The most current material on stochastic scheduling, including correct scheduling of safety time and the use of simulation for optimization, is then presented and integrated with deterministic models. Additional topical coverage includes: Extensions of the basic model Parallel-machine models Flow shop scheduling Scheduling groups of jobs The job shop problem Simulation models for the dynamic job shop Network methods for project scheduling Resource-constrained project scheduling Stochastic and safe scheduling Extensive end-of-chapter exercises are provided, some of which are spreadsheet-oriented, and link scheduling theory to the most popular analytic platform among today's students and practitioners—the Microsoft Office Excel® spreadsheet. Extensive references direct readers to additional literature, and the book's related Web site houses material that reinforces the book's concepts, including research notes, data sets, and examples from the text. Principles of Sequencing and Scheduling is an excellent book for courses on sequencing and scheduling at the upper-undergraduate and graduate levels. It is also a valuable reference for researchers and practitioners in the fields of statistics, computer science, operations research, and engineering.

Download or read book Model and Algorithms for Scheduling Uniform Parallel Machines written by P Senthilkumar and published by Independently Published. This book was released on 2024-01-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production scheduling helps businesses become more productive and efficiently satisfy consumer needs. Because it falls within the combinatorial category, scheduling work on uniform parallel computers to minimize the makespan measure is a difficult problem under single machine scheduling. The goal of this essay is to show how to design an effective algorithm for this particular situation. The introduction chapter of this text covers single machine scheduling with a single machine, single machine scheduling with parallel machines, and research gap of unform parallel machine scheduling. The goals of the challenge, the assumptions behind the scheduling of uniform parallel machines, and the plan for developing the algorithms are all presented in Chapter 2, which describes the problem. A model and an example of the model utilizing a small size problem are provided in Chapter 3 on the mathematical model for uniform parallel machines scheduling to minimize makespan. The simulated annealing algorithm to minimize makespan in the single machine scheduling problem with uniform parallel machines is presented in Chapter 4. It includes an overview of the algorithm, its skeleton, three newly developed simulated annealing algorithms, and a comparison of them to determine which is the best. The development of a GA-based strategy to reduce the uniform parallel machine scheduling makespan is presented in Chapter 5. This covers the basic structure of the genetic algorithm, factors that impact the GA algorithm, techniques for assigning tasks to machines, and crossover strategies. Additionally, it entails the creation of four GA-based heuristics to reduce makespan and a comparison of them to determine which GA-based heuristic is optimum for scheduling jobs on uniform parallel computers. In order to determine which is optimal, the best GA-based heuristic and the best simulated annealing technique are compared in Chapter 6 to minimize the makespan of scheduling jobs on uniform parallel computers. Appendix 1 for replication 1 and Appendix 2 for replication 2 contain the data needed to test the heuristics in Chapter 4, Chater 5, and Chapter 6. The author expresses gratitude to all of his university colleagues and academicians for their support in releasing this work. The writing style of this text is simple to read. P.
