Paul Williams, a leading authority on modeling in integer programming, has written a concise, readable introduction to the science and art of using modeling in logic for integer programming. Written for graduate and postgraduate students, as well as academics and practitioners, the book is divided into four chapters that all avoid the typical format of definitions, theorems and proofs and instead introduce concepts and results within the text through examples. References are given at the end of each chapter to the more mathematical papers and texts on the subject, and exercises are included to reinforce and expand on the material in the chapter. Methods of solving with both logic and IP are given and their connections are described. Applications in diverse fields are discussed, and Williams shows how IP models can be expressed as satisfiability problems and solved as such.

Das Buch gibt einen kompakten, aber umfassenden Überblick über das Problemlösen und Programmieren mit "Constraints" (Randbedingungen). Diese aktuelle Programmiermethodik ermöglicht es, Aufgaben direkt zu formulieren und effizient zu lösen. Sie gewinnt zusehends Bedeutung in Anwendungsbereichen wie Kombinatorische Suchprobleme (z.B. Zeitplanen, Layout-Optimierung), Berechnungen (Finanzanalyse), Simulation (Hardware-Verifikation) oder allgemein Schließen und Rechnen mit ungenauer oder unvollständiger Information (z.B. Kostenschätzung). Die theoretisch fundierte Darstellung mit Aufgaben und Anwendungsbeispielen aus der Praxis ist in der Lehre erprobt, aber auch für Forscher und Praktiker von Nutzen.

This book’s aim is to provide several different kinds of information: a delineation of general metaheuristics methods, a number of state-of-the-art articles from a variety of well-known classical application areas as well as an outlook to modern computational methods in promising new areas. Therefore, this book may equally serve as a textbook in graduate courses for students, as a reference book for people interested in engineering or social sciences, and as a collection of new and promising avenues for researchers working in this field.

The 5th International Conference on Integration of AI and OR Techniques in Constraint Programming for Combinatorial Optimization Problems (CPAIOR 2008) was held in Paris, France May 20–23, 2008. The purpose of this conference series is to bring together researchers in the ?elds of constraint programming, arti?cial intelligence, and operations research to explore ways of solving large-scale, practical optimization problems through integration and hybridization of the ?elds’ di?erent techniques. Through the years, this research community is discovering that the ?elds have much in c- mon, and there has been tremendous richness in the resulting cross-fertilization of ?elds. This year, we allowed submissions of both long (15 page) and short (5 page) papers, with short papers either being original work, a reduced version of a long paper, or an extended abstract of work published elsewhere. We were not s- prised by the 69 submissions in the long paper category: this is an active ?eld with many researchers. We were surprised by the 61 short paper submissions. This was far more than predicted. With 130 high-quality submissions, compe- tion for acceptance in this year’s program was particularly ?erce. In the end, we accepted 18 long papers and 22 short papers for presentation and publication in this volume.

In conventional mathematical programming, coefficients of problems are usually determined by the experts as crisp values in terms of classical mathematical reasoning. But in reality, in an imprecise and uncertain environment, it will be utmost unrealistic to assume that the knowledge and representation of an expert can come in a precise way. The wider objective of the book is to study different real decision situations where problems are defined in inexact environment. Inexactness are mainly generated in two ways – (1) due to imprecise perception and knowledge of the human expert followed by vague representation of knowledge as a DM; (2) due to huge-ness and complexity of relations and data structure in the definition of the problem situation. We use interval numbers to specify inexact or imprecise or uncertain data. Consequently, the study of a decision problem requires answering the following initial questions: How should we compare and define preference ordering between two intervals?, interpret and deal inequality relations involving interval coefficients?, interpret and make way towards the goal of the decision problem? The present research work consists of two closely related fields: approaches towards defining a generalized preference ordering scheme for interval attributes and approaches to deal with some issues having application potential in many areas of decision making.

This book has been designed to fill a market need for a shorter book which can be covered in 6 weeks to one college quarter. The cases will emphasize more than just individual quantitative methods for specific situations; they will help students with problem diagnostics and modeling processes. Some topics from MIS will be integrated as well. It will be a durable and striking book since it is to be case bound with a four-color cover. The book consists of 30% text and 70% cases. The text will also include a data disk.
