Available in PDF, EPUB and Kindle. Book excerpt: Optimization has been a central topic in most scientific disciplines for centuries. Continuous optimization has long benefited from well-established techniques of calculus. Discrete optimization, on the other hand, has risen to prominence quite recently. Advances in combinatorial optimization and integer programming in the past few decades, together with the improvement of computer hardware have enabled computer scientists to approach the the problems in this area both theoretically and computationally. However, obtaining the exact solution for many discrete optimization problems remains is still a challenging task, mainly because most of these problems are NP-hard. Under the widespread assumption that P ≠ NP, these problems are intractable from a computational complexity standpoint. Therefore, we should settle for near-optimal solutions. In this thesis, we develop techniques to obtain solutions that are provably close to the optimal for different indivisible resource allocation problems. Indivisible resource allocation encompasses a large class of problems in discrete optimization which can appear in disguise in various theoretical or applied settings. Specifically, we consider two indivisible resource allocation problems. The first one is a variant of the vehicle routing problem known as Skill Vehicle Routing problem, in which the aim is to obtain optimal tours for a fleet of vehicles that provides service to a set of customers. Each of the vehicles possesses a particular set of skills suitable for a subset of the tasks. Each customer, based on the type of service he requires, can only be served by a subset of vehicles. We study this problem computationally and find either the optimal solution or a relatively tight bound on the optimal solution on fairly large problem instances. The second problem involves approximation algorithms for two versions of the classic scheduling problem, the restricted $R.

Available in PDF, EPUB and Kindle. Book excerpt: The third edition of this textbook comprehensively discusses global supply chain and operations management (SCOM), combining value creation networks and interacting processes. It focuses on operational roles within networks and presents the quantitative and organizational methods needed to plan and control the material, information, and financial flows in supply chains. Each chapter begins with an introductory case study, while numerous examples from various industries and services help to illustrate the key concepts. The book explains how to design operations and supply networks and how to incorporate suppliers and customers. It examines how to balance supply and demand, a core aspect of tactical planning, before turning to the allocation of resources to meet customer needs. In addition, the book presents state-of-the-art research reflecting the lessons learned from the COVID-19 pandemic, and emerging, fast-paced developments in the digitalization of supply chain and operations management. Providing readers with a working knowledge of global supply chain and operations management, with a focus on bridging the gap between theory and practice, this textbook can be used in core, specialized, and advanced classes alike. It is intended for a broad range of students and professionals in supply chain and operations management.
