Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to metaheuristics as applied to vehicle routing problems. Several implementations are given as illustrative examples, along with applications to several typical vehicle routing problems. As a first step, a general presentation intends to make the reader more familiar with the related field of logistics and combinatorial optimization. This preamble is completed with a description of significant heuristic methods classically used to provide feasible solutions quickly, and local improvement moves widely used to search for enhanced solutions. The overview of these fundamentals allows appreciating the core of the work devoted to an analysis of metaheuristic methods for vehicle routing problems. Those methods are exposed according to their feature of working either on a sequence of single solutions, or on a set of solutions, or even by hybridizing metaheuristic approaches with others kind of methods.

Available in PDF, EPUB and Kindle. Book excerpt: Decomposition has been used in solving numerous problems in mathematics, computer science, engineering, management, and operations research. In this dissertation, we use decomposition methods to solve three practical combinatorial optimization problems arising in telecommunication and airline planning. In the first part of the dissertation, we study a redundant multicast routing problem with group diverse constraint (RMRGD) that arises in many network applications such as communication systems, power supply distribution systems, transportation networks, etc. We propose three mixed integer programming (MIP) models, an edge-based, a path-based, and a tree-based model, to solve RMRGD. We proposed two decomposition methods based on the column generation and branch-and-price to solve the path-based and tree-based models. Our empirical results suggest that the edge-based model is superior in solving small and mid-sized problems, whereas the tree-based model performs better for large problems. In the second part of the dissertation, we study the flight conflict resolving problem (FCR). The purpose of flight conflict re-scheduling problem is to provide a flight schedule that minimizes the total penalty cost of schedule changes, while maintaining the FAA separation standard between aircrafts. We propose a set-partitioning-based flight sequence model (FSM) that selects an optimal set of flight sequences to minimize the total penalty cost. We also extend the FSM to consider equity among airlines because such corporate decision making (CDM)-feature is necessary and critical for the future aviation systems. The computation results show the proposed solution methods outperform other solution methods, and solve the real life test cases optimally within reasonable time. In the third part of the dissertation, the aircraft maintenance routing problem is studied. The aircraft maintenance routing problem is aimed at scheduling the aircraft rotations so that adequate maintenance opportunities are provided to every aircraft in the fleet. In this dissertation, we present two new compact rotation-tour network representations for the daily aircraft maintenance routing problem (AMR) and the weekly aircraft maintenance routing problem (WAMR), and propose new mixed-integer linear programming formulations to solve these two problems. The computational study suggests the proposed models are able to solve large real-life test instances optimally in reasonable time.
Download or read book Hybrid Metaheuristics written by Christian Blum and published by Springer. This book was released on 2016-05-23 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the most prominent and some promising new, general techniques that combine metaheuristics with other optimization methods. A first introductory chapter reviews the basic principles of local search, prominent metaheuristics, and tree search, dynamic programming, mixed integer linear programming, and constraint programming for combinatorial optimization purposes. The chapters that follow present five generally applicable hybridization strategies, with exemplary case studies on selected problems: incomplete solution representations and decoders; problem instance reduction; large neighborhood search; parallel non-independent construction of solutions within metaheuristics; and hybridization based on complete solution archives. The authors are among the leading researchers in the hybridization of metaheuristics with other techniques for optimization, and their work reflects the broad shift to problem-oriented rather than algorithm-oriented approaches, enabling faster and more effective implementation in real-life applications. This hybridization is not restricted to different variants of metaheuristics but includes, for example, the combination of mathematical programming, dynamic programming, or constraint programming with metaheuristics, reflecting cross-fertilization in fields such as optimization, algorithmics, mathematical modeling, operations research, statistics, and simulation. The book is a valuable introduction and reference for researchers and graduate students in these domains.

Download or read book Handbook of Metaheuristics written by Michel Gendreau and published by Springer. This book was released on 2018-09-20 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of this handbook is designed to provide a broad coverage of the concepts, implementations, and applications in metaheuristics. The book’s chapters serve as stand-alone presentations giving both the necessary underpinnings as well as practical guides for implementation. The nature of metaheuristics invites an analyst to modify basic methods in response to problem characteristics, past experiences, and personal preferences, and the chapters in this handbook are designed to facilitate this process as well. This new edition has been fully revised and features new chapters on swarm intelligence and automated design of metaheuristics from flexible algorithm frameworks. The authors who have contributed to this volume represent leading figures from the metaheuristic community and are responsible for pioneering contributions to the fields they write about. Their collective work has significantly enriched the field of optimization in general and combinatorial optimization in particular.Metaheuristics are solution methods that orchestrate an interaction between local improvement procedures and higher level strategies to create a process capable of escaping from local optima and performing a robust search of a solution space. In addition, many new and exciting developments and extensions have been observed in the last few years. Hybrids of metaheuristics with other optimization techniques, like branch-and-bound, mathematical programming or constraint programming are also increasingly popular. On the front of applications, metaheuristics are now used to find high-quality solutions to an ever-growing number of complex, ill-defined real-world problems, in particular combinatorial ones. This handbook should continue to be a great reference for researchers, graduate students, as well as practitioners interested in metaheuristics.
