This volume contains selected papers presented at the International Conference on Operations Research SOR 2002 held at the University of Klagenfurt from Sep- tember 2 to September 5, 2002. The conference was organized under the auspices of the German, the Swiss and the Austrian Operations Research societies - Gesellschaft fiir Operations Research e.V. (GOR) - Schweizerische Vereinigung fiirOperations Research (SVOR) - Osterreichische Gesellschaft fiirOperations Research (OGOR). After Vienna (1990), Berlin (1994) and Ziirich (1998) this has been the fourth time that the three societies organized ajoint conference. The conference was attended by more than 400 participants from countries all over the world which demonstrates the broad interest in all aspects ofOperations Research. The scientific program of the conference consisted of 4 plenary lectures, 5 semi plenary lectures, and about 320 contributed papers which have been presented in 16 sections. Due to the limited number of pages available for the proceedings vol- ume, the length of each article as well as the total number ofcontributions had to be restricted.The decision on the acceptance of papers for the proceedings has been made in close eo operation with the section chairmen and was based on their suggestions. We wish to express our sincere thanks to the chairmen for supporting our editorial work by refereeing the manuscripts and letting us have their advice. We also would like to thank Dr. Wemer Muller from Springer-Verlag for his support in publishing this proceedings volume so quickly.

The joint work of Robin Pope, Johannes Leitner and Ulrike Leopold- Wildburger presented in this little book makes a strong point for a new approach to decision making under risk. It emphasizes aspects of risk preferences largely neglected in the theoretical and experimental lite- ture. Before the outcome of a risky decision is known a decision maker may feel worries or thrills about what will happen at the end. It is c- vincingly argued that the anticipation of such ”secondary satisfactions” is, and should be, an important in?uence on the decision. The questi- naire data and the experiments support this view. The answers of participants in the questionnaires about the reasons for their decision are an important basis for the evaluation of the - periment. The evaluation of these questionnaires has led to impressive ?ndings. Like other commonly used research techniques, the analysis of introspective information in questionnaires is not absolutely reliable. Nevertheless it is an extremely valuable source of insight into moti- tional forces, insu?ciently exploited in economics. It is not my task to give a preview of the book, but I would like to encourage the reader to discover the remarkable results of an unusual theoretical and experimental approach to decision making under risk.

A Silverman game is a two-person zero-sum game defined in terms of two sets S I and S II of positive numbers, and two parameters, the threshold T 1 and the penalty 0. Players I and II independently choose numbers from S I and S II, respectively. the igher number wins 1, unless it is at least T times as large as the other, in which case it loses v. Equal numbers tie. Such a game might be used to model various bidding or spending situations in which within some bounds the higher bidder or bigger spender wins, but loses if it is overdone. such situations may include spending on armaments, advertising spending or sealed bids in an auction. Previous work has dealt mianly with special cases. In this work recent progress for arbitrary discrete sets S I and S II is presented. Under quite general conditions, these games reduce to finite matrix games. A large class of games are completely determined by the diagonal or the matrix, and it is shown how the great majority of these appear to have unique optimal strategies. The work is accessible to all who are familiar with basic noncooperative game theory.

This book brings together in an efficient and unified way virtually all that has been learned about this intriguing class of games since its appearance on the scene in 1979. The game on discrete sets is reduced to minimal strategy sets on which the payoff matrix has a canonical structure, and the game on intervals is analyzed for all possible pairs of intervals. For most cases, optimal strategies and game value can be explicitly obtained.

Das Buch enthält ausgewählte Vorträge, die anläßlich des Symposiums über Operations Research (SOR'95) in der Zeit vom 13.-15.9.1995 an der Universität Passau gehalten wurden. Der Leser erhält einen Einblick in neueste Forschungsergebnisse auf dem Gebiet des Operations Research. Der Sammelband demonstriert eindrucksvoll das weite Spektrum der vom Operations Research heute behandelten Thematiken. Neben primär methodischen Fragestellungen bilden praxisorientierte Themen wie Anwendungsberichte aus der Praxis, im Umweltschutz, der Logistik und Verkehrsplanung einen Schwerpunkt. Deutlich wird auch die Ausstrahlung des Operations Research in andere wissenschaftliche Disziplinen wie Informatik, Ökonomie und Wirtschaftsinformatik.

Die fünfte Auflage dieses Lehrbuchs wurde in wesentlichen Punkten überarbeitet und ergänzt und ist somit fast ein neues Buch geworden. Unser Ziel ist es, Studierenden der Wirtschaftswissenschaften jene mathematischen Grundkenntnisse zu vermitteln, die im weiteren Studium benötigt werden. Demgemäß werden Lineare Algebra, Analysis und Optimierung sowohl grundsätzlich als auch in der Anwendung auf ökonomische Fragestellungen behandelt. Ausgeklammert bleibt dabei die Stochastik. Auf mathematische Präzision wurde durchaus Wert gelegt, ohne diesen Begriff überzustrapazieren. Beispiele, einige zum Verständnis der Methodik, andere mit Bezug auf wirtschaftliche Probleme, ergänzen den Text. Zum Verständnis sollten die mathematischen Grundkenntnisse aus der Schule leicht ausreichen. Das Buch ist speziell für Studienanfänger gestaltet. Abbildungen ergänzen den Stoff und sollen die Inhalte leichter verständlich machen.

This title represents an ambitious undertaking, namely a broad view on the nature of intelligent decision making, which is characterized by the use of models and methods in the framework of decision support for management. With this title we want to reflect the scope of our field, but, at the same time, honor our colleague th Paul Stahly on the occasion of his 65 birthday. Paul Stahly has over decades invested his energy in developing the area of Operations Research from such a broad point of view. He has done this not only at his chairs at the HSG / University of St. Gallen and the University of Linz, but also on a broad international level as editor of ITOR and as influential member of all the Operations Research societies in the German speaking countries. He has, in particular, enriched our area by application-oriented research and industrial projects in fields such as logistics, emergency planning, [mance, and others, and he was pivotal in strengthening the cooperation between the national and international OR societies, particular in the German speaking area. VI Consequently, many colleagues who partly cooperated very closely with him, have contributed to this monograph. Some of these contributions have been presented at a colloquium in January 2001 in St. Gallen in honor of Paul Stahly. This colloquium was attended by many colleagues coming from Germany, Austria, Switzerland, Italy and even from the United States.

Das Buch ist somit ein unentbehrlicher Leitfaden für Diplomanden und Doktoranden sowie für Schüler höherer Jahrgangsstufen. Die dritte Auflage wurde grundlegend überarbeitet, erweitert und aktualisiert.

This book provides insights that are useful for people with interests in Operations Research, statistics and econometrics. Each contribution offers a snapshot out from interesting topics. The relationships and interconnectivities between decisions and models from different economic fields lead to a better understanding of the modern field of Operations Research. The book focuses on modelling as an activity rather than on techniques and programming. Divided into three parts, part one provides decision theoretical models, part two provides several theoretical and empirical papers concerning statistics and econometrics. Finally, part three provides an up-to-date account of Operations Research.

The book presents a broad view on the nature of intelligent decision-making which is characterized by the use of models and methods in the framework of decision support for management. Contributions to this volume dedicated to Paul Stahly on the occasion of his 65th birthday include theoretical research and applications in optimization, operations research as well as decision support and management systems.
