Available in PDF, EPUB and Kindle. Book excerpt: Scheduling is defined as the process of assigning operations to resources over time to optimize a criterion. Problems with scheduling comprise both a set of resources and a set of a consumers. As such, managing scheduling problems involves managing the use of resources by several consumers. This book presents some new applications and trends related to task and data scheduling. In particular, chapters focus on data science, big data, high-performance computing, and Cloud computing environments. In addition, this book presents novel algorithms and literature reviews that will guide current and new researchers who work with load balancing, scheduling, and allocation problems.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We consider the problem of scheduling n independent jobs on m unrelated parallel machines. Each job has to be processed by exactly one machine, processing job j on machine i requires p[subscript ij] time units, and the objective is to minimize the makespan, i.e. the maximum job completion time. We focus on the case when m is fixed and develop a fully polynomial approximation scheme whose running time depends only linearly on n. In the second half of the paper we extend this result to a variant of the problem, where processing job j on machine i also incurs a cost of c[subscript ij], and thus there are two optimization criteria: makespan and cost. We show that for any fixed m, there is a fully polynomial approximation scheme that, given values T and C, computes for any fixed [epsilon]> 0 a schedule in O(n) time with makespan at most (1 + [epsilon])T and cost at most (1 + [epsilon])C, if there exists a schedule of makespan T and cost C."

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An abundance of research exists studying parallel machine scheduling, but only a portion of this research has focused on the case with non-availability periods and job resumability factors. Research considering this case has mostly focused on limited cases such as a small, fixed number of machines or fixed number of non-availability periods. In this research, we improve the runtime of the model by Beaton et al. (2016) who proposed a mixed-integer linear programming (MILP) model allowing an arbitrary number of machines, non-availability periods, and resumability factor for small instances of the makespan minimization case. We propose a new MILP model for the Total Weighted Completion Time (TWC) case and two constraint programming (CP) models for both the makespan and TWC cases and find that the CP models outperform the MILP for the TWC case. We confirm that the well-known Weighted Shortest Processing Time heuristic works well for large TWC instances.

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.
Download or read book Scheduling written by Michael L. Pinedo and published by Springer Science & Business Media. This book was released on 2012-01-07 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of the well established text Scheduling - Theory, Algorithms, and Systems provides an up-to-date coverage of important theoretical models in the scheduling literature as well as significant scheduling problems that occur in the real world. It again includes supplementary material in the form of slide-shows from industry and movies that show implementations of scheduling systems. The main structure of the book as per previous edition consists of three parts. The first part focuses on deterministic scheduling and the related combinatorial problems. The second part covers probabilistic scheduling models; in this part it is assumed that processing times and other problem data are random and not known in advance. The third part deals with scheduling in practice; it covers heuristics that are popular with practitioners and discusses system design and implementation issues. All three parts of this new edition have been revamped and streamlined. The references have been made completely up-to-date. Theoreticians and practitioners alike will find this book of interest. Graduate students in operations management, operations research, industrial engineering, and computer science will find the book an accessible and invaluable resource. Scheduling - Theory, Algorithms, and Systems will serve as an essential reference for professionals working on scheduling problems in manufacturing, services, and other environments. Reviews of third edition: This well-established text covers both the theory and practice of scheduling. The book begins with motivating examples and the penultimate chapter discusses some commercial scheduling systems and examples of their implementations." (Mathematical Reviews, 2009)

Available in PDF, EPUB and Kindle. Book excerpt: Motivated by problems in distributed computing, this thesis presents the first nontrivial polynomial time approximation algorithms for an important class of machine scheduling problems. We study the family of preemptive minimum makespan scheduling problems where jobs have stochastic processing requirements and provide the first approximation algorithms for these problems when machines have unrelated speeds. We show a series of algorithms that apply given increasingly general classes of precedence constraints on jobs. Letting n and m be, respectively, the number of jobs and machines in an instance, when jobs need an exponentially distributed amount of processing, we give: -- An O(log log min {m, n} )-approximation algorithm when jobs are independent; -- An 0 (log(n + m) log log min {m, n})-approximation algorithm when precedence constraints form disjoint chains; and, -- An O(log n log(n + m) log log min {m, n} )-approximation algorithm when precedence constraints form a directed forest. Very simple modifications allow our algorithms to apply to more general distributions, at the cost of slightly worse approximation ratios. Our O(log log n)-approximation algorithm for independent jobs holds when we allow restarting instead of preemption. Here jobs may switch machines, but lose all previous processing if they do so. We also consider problems in the framework of scheduling under uncertainty. This model considers jobs that require unit processing on machines with identical speeds. However, after processing a job to completion, a machine has an (unrelated) probability of failing and leaving the job uncompleted. This difficulty is offset by allowing multiple machines to process a job simultaneously. We prove that this model is equivalent to a slightly modified version of the family of problems described above and provide approximation algorithms for analogous problems with identical ratios.
