This paper describes a tabu search heuristic for the vehicle routing problem with time windows (VRPTW). The tabu search incorporates an exchange heuristic which is specifically designed for problems with time windows. Computational results on the standard set of problems of Solomon are included at the end of the paper.

Masterarbeit aus dem Jahr 2011 im Fachbereich BWL - Beschaffung, Produktion, Logistik, Note: Sehr gut, Karl-Franzens-Universität Graz (Produktion und Logistik), Sprache: Deutsch, Abstract: Der Hauptbestandteil dieser Arbeit ist das Testen verschiedener lokaler Suchoperatoren für eine Erweiterung des gutbekannten Vehicle Routing Problems. Diese erst vor kurzem eingeführte Erweiterung wurde notwendig um ein Routenplanungsproblem zu lösen, das daraus bestand, Getränke und Tabakwaren in dichtbesiedelten Groÿstädten in Brasilien auszuliefern. Es wurde nun versucht herauszunden, welche der VRPTW Operatoren geeignet sind, um das Vehicle Routing Problem with Time Windows and Multiple Deliverymen (VRPTWMD) möglichst gut zu lösen. Insgesamt wurden vier Operatoren implementiert, wobei Relocate und Ejection Chains auf die Routenminimierung abzielen und Cross bzw. 2-opt entsprechend die gefahrene Distanz verringern sollten. Um die Operatoren zu testen, wurden die benötigten Startlösungen mit der von Solomon entwickelten I1 Einfügeheuristik generiert. Die Erkenntnisse aus den Tests wurden schieÿlich dazu verwendet, eine best performance Variante zu entwickeln, welche anhand der Solomon Instanzen R101 bis R112 getestet wurde. Die Ergebnisse der Tests benden sich am Ende der Arbeit. The Vehicle Routing Problem with time windows is a well studied problem in literature. The extension to Vehicle Routing Problem with Time Windows and Multiple Deliverymen (VRPTWMD) has been proposed to solve a delivery problem of commodities, like beverages and tobacco in highly populated areas in Brazil. This rather new problem structure in the VRPTW context, is the main subject of the work. In this thesis, the aim is to nd out, which operators used for VRP are most suitable for the VRPTWMS. Relocate and Ejection Chain operators were tested for truck and deliverymen reduction, Cross and 2-opt were implemented to reduce distance. The Solomon I1 insertion heuristic was used to obtain starting solutions, for the tests and the nal version of the algorithm proposed. To complete this work, several tests have been performed and the results of the algorithm running Solomon R101- R112 instances can be found at the end.

Meta-Heuristics: Advances and Trends in Local Search Paradigms for Optimizations comprises a carefully refereed selection of extended versions of the best papers presented at the Second Meta-Heuristics Conference (MIC 97). The selected articles describe the most recent developments in theory and applications of meta-heuristics, heuristics for specific problems, and comparative case studies. The book is divided into six parts, grouped mainly by the techniques considered. The extensive first part with twelve papers covers tabu search and its application to a great variety of well-known combinatorial optimization problems (including the resource-constrained project scheduling problem and vehicle routing problems). In the second part we find one paper where tabu search and simulated annealing are investigated comparatively and two papers which consider hybrid methods combining tabu search with genetic algorithms. The third part has four papers on genetic and evolutionary algorithms. Part four arrives at a new paradigm within meta-heuristics. The fifth part studies the behavior of parallel local search algorithms mainly from a tabu search perspective. The final part examines a great variety of additional meta-heuristics topics, including neural networks and variable neighbourhood search as well as guided local search. Furthermore, the integration of meta-heuristics with the branch-and-bound paradigm is investigated.

Column Generation is an insightful overview of the state of the art in integer programming column generation and its many applications. The volume begins with "A Primer in Column Generation" which outlines the theory and ideas necessary to solve large-scale practical problems, illustrated with a variety of examples. Other chapters follow this introduction on "Shortest Path Problems with Resource Constraints," "Vehicle Routing Problem with Time Window," "Branch-and-Price Heuristics," "Cutting Stock Problems," each dealing with methodological aspects of the field. Three chapters deal with transportation applications: "Large-scale Models in the Airline Industry," "Robust Inventory Ship Routing by Column Generation," and "Ship Scheduling with Recurring Visits and Visit Separation Requirements." Production is the focus of another three chapters: "Combining Column Generation and Lagrangian Relaxation," "Dantzig-Wolfe Decomposition for Job Shop Scheduling," and "Applying Column Generation to Machine Scheduling." The final chapter by François Vanderbeck, "Implementing Mixed Integer Column Generation," reviews how to set-up the Dantzig-Wolfe reformulation, adapt standard MIP techniques to the column generation context (branching, preprocessing, primal heuristics), and deal with specific column generation issues (initialization, stabilization, column management strategies).

Hardbound. This collection of original research papers is dedicated to the analysis and solution of vehicle routing problems. Vehicle routing is a branch of operations research that has attracted a great deal of research attention over the years. The accumulated body of knowledge has resulted in algorithms and insights that have enabled companies and organizations in both the public and private sectors to save from 5% to 10% on distribution related costs. The volume brings together, in a comprehensive way, the theory and practice of vehicle routing in book form for the first time.
