The last fifteen or twenty years have been marked by fundamental advances in the sources of complex behavior in micro- and macro-economics, in the practical and methodological implications of such behavior, and in the methods and tools appropriate to cope with them. Much of these developments have been driven by the recognition and acceptance by economists of approaches initiated in other fields - such as non-linear dynamics, statistical physics, network theory, biology, computer science, and the use of computational methods as problem-solving tools - giving rise to important and innovative impulses to economic thinking. The sixteen papers in this book -- the fourteenth volume in the series International Symposia in Economic Theory and Econometrics - reflect from various perspectives this recent evolution. They are the outgrow from a selection of communications presented at the COMPLEXITY2000 workshop held in Aix en Provence, France, 4-6 May 2000 - a workshop that brought together, from twenty-two nations, almost seventy economists, mathematicians, biologists and physicists interested in complex phenomena. All papers were strictly refereed in the intended tradition of the series: to provide journal quality collections of research papers of unusual importance in areas of currently highly visible activity within the economics profession. With its selection of articles, the book presents an overview of advanced contributions to complexity in economics and social system, such as chaotic dynamics and multiple equilibria, agent-based models, applications of genetic algorithms, non-equilibrium macro-dynamics, information transmission, learning mechanisms. Although the papers address economic problems, the authorship and the perspectives presented are interdisciplinary and provide therefore a number of innovative insights and solutions to classical or new questions.

mso-ansi-language: EN-US;">At the 15th Viennese Workshop on Optimal Control and Dynamic Games, held in July 2022, experts in economics and the management sciences identified a concerning trend: static decision-making models, while less effective than dynamic ones, are becoming increasingly prevalent.

This volume collects research papers addressing topical issues in economics and management with a particular focus on dynamic models which allow to analyze and foster the decision making of firms in dynamic complex environments. The scope of the contributions ranges from daily operational challenges firms face to strategic choices in dynamic industry environments and the analysis of optimal growth paths. The volume also highlights recent methodological developments in the areas of dynamic optimization, dynamic games and meta-heuristics, which help to improve our understanding of (optimal) decision making in a fast evolving economy.

Since the days of Lev Pontryagin and his associates, the discipline of Optimal Control has enjoyed a tremendous upswing – not only in terms of its mathematical foundations, but also with regard to numerous fields of application, which have given rise to highly active research areas. Few scholars, however, have been able to make contributions to both the mathematical developments and the (socio-)economic applications; Vladimir Veliov is one of them. In the course of his scientific career, he has contributed highly influential research on mathematical aspects of Optimal Control Theory, as well as applications in Economics and Operations Research. One of the hallmarks of his research is its impressive breadth. This volume, published on the occasion of his 65th birthday, accurately reflects that diversity.         The mathematical aspects covered include stability theory for difference inclusions, metric regularity, generalized duality theory, the Bolza problem from a functional analytic perspective, and fractional calculus. In turn, the book explores various applications of control theory, such as population dynamics, population economics, epidemiology, optimal growth theory, resource and energy economics, environmental management, and climate change. Further topics include optimal liquidity, dynamics of the firm, and wealth inequality.

This volume collects research papers addressing topical issues in economics and management with a particular focus on dynamic models which allow to analyze and foster the decision making of firms in dynamic complex environments.

Die Operations Research Proceedings 1989 dokumentieren die Vorträge, die auf der 18. Jahrestagung der Deutschen Gesellschaft für Operations Research in der Zeit vom 13. bis 15. September 1989 gehalten worden sind. In dem Band sind die Fassungen von 5 Plenar- und 105 Fachvorträgen enthalten, von denen 60 in Lang-, der Rest in Kurzfassungen aufgenommen sind. Im einzelnen sind Beiträge zu folgenden Teilgebieten zusammengestellt: - Operations Research in der Industrie - Operations Research in Banken und Versicherungen - Produktion - Marketing - Logistik und Verkehr - Statistik, Datenanalyse und Prognose - Organisation und Entscheidungstheorie - Decision Support-Systeme und Künstliche Intelligenz - Wirtschaftsinformatik - Stochastische Prozesse einschl. Zuverlässigkeits- und Bedienungstheorie - Mathematische Optimierung - Spieltheorie - Kontrolltheorie

Yom 28. - 31. August 1990 fand die 19. Jahrestagung der Deutschen Gesellschaft fur Operations Research e. V. an der Wirtschaftsuniversitat Wien statt. Erstmals wurde diese Jahrestagung zusammen mit den anderen deutschsprachigen OR-Gesellschaften, der Gesell- schaft fur Mathematik, Okonomie und Operations Research (GMOOR), der Osterreichi- schen Gesellschaft fur Operations Research (OGOR) und der Schweizerischen Vereinigung fur Operations Research (SVOR) abgehalten. Diese internationale Tagung stand unter dem Titel Operations Research 1990. Fast 1000 Teilnehmer aus 38 Lander machten die Tagung zu einem internationalen GroBereignis. Am stiirksten vertreten waren dabei die Lander BRD (mit 381 Teilnehmern), Osterreich (91), Niederland~ (57), USA (44), Schweiz (38), Italien (35) sowie Kanada (23). Dank der geiinderten politischen Lage konnten knapp 100 Teilnehmer aus den (ehemaligen) sozialistischen Staaten die Tagung besuchen. Dies wurde ermoglicht dank der vielfiiltigen finanziellen Unterstiitzungen durch die Privatwirtschaft und durch das osterreichische Bundesministerium fur Wissenschaft und Forschung.Die Operations Research Proceedings 1990 dokumentieren nur einen kleinen Teil der iiber 600 Vortrage. Von den zur Publikation eingereichten Langfassungen konnten aufgrund der beschriinkten Seitenzahl nur 50 % angenommen werden. Zum groBen Bedauern des Pro- grammausschusses waren aufgrund der beschriinkten Seitenzahl von einer Ablehnung auch ausgezeichnete Manuskripte betroffen. Allein die Veroffentlichung der Kurzfassungen aller prasentierten Vortriige Mtte den Proceedingsband gesprengt. Aus diesem Grunde werden in diesen Proceedings erstmals keine Kurzfassungen publiziert und damit auf eine vollstandige Dokumentation der Tagung verzichtet. Es solI aber hier auf zwei weitere Publikationen hin- gewiesen werden, in denen Vortrage der Tagung Operations Research 90 enthalten sind.

Dynamic optimization is rocket science – and more. This volume teaches how to harness the modern theory of dynamic optimization to solve practical problems, not only from space flight but also in emerging social applications such as the control of drugs, corruption, and terror. These innovative domains are usefully thought about in terms of populations, incentives, and interventions, concepts which map well into the framework of optimal dynamic control. This volume is designed to be a lively introduction to the mathematics and a bridge to these hot topics in the economics of crime for current scholars. We celebrate Pontryagin’s Maximum Principle – that crowning intellectual achievement of human understanding – and push its frontiers by exploring models that display multiple equilibria whose basins of attraction are separated by higher-dimensional DNSS "tipping points". That rich theory is complemented by numerical methods available through a companion web site.

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 first Joint Meeting of the Austrian and Swiss Operations Research Societies was held at the University of Technology in Vienna, Austria, from 22-24 September 1980. A selection of the papers then presented are published in this volume. The papers included provide a picture of Operations Research as a discipline comprehending various methods and models. The volume is divided into two parts. The first part contains papers on mathematical programming and optimal control theory. Moreover, two papers on decision and game theory are included as well as two on biomathematical to~ics. Being more heterogeneous, the second part, on stochastic models, includes such topics as queueing theory, econometrics and time series analysis. As a special feature of the symposium, a series of applications of OR models in energy planning were discussed, e.g., load and demand forecasting, power distribution and extension planning, reliability and work-safety, etc. These papers have been incorporated into parts one and two according to the models used.
