Invited contributions from distinguished practitioners and methodologists of operational research and applied systems analysis which represent a true state-of-the-art and which provide, perhaps for the first time, a coherent, interlocking, set of ideas which may be considered the foundations of the subject as a science in its own right.

Further Developments in Operational Research is a collection of articles on fields such as behavioral science, corporate planning, and artificial intelligence. Subjects in forecasting, risk analysis, and network analysis are likewise reviewed. The book discusses statistical forecasting in detail. Graphs, networks, and uses of such networks are provided. A chapter of the book covers the creation and implementation of expert systems. Risk engineering is an integrated approach to all aspects of risk analysis. It identifies and quantifies uncertainty and advances methods in order to modify associated risks through effective and efficient decisions. A review of the models used in forecasting is then provided. This section includes concepts such as hypergraphs, network flows, and tools of graph theory. The historical background and developments in artificial intelligence are also featured in the book. Statistical forecasting is presented completely. The book can serve as a useful tool for programmers, forecasters, statisticians, psychologists, students, and researchers.

Developments in Operational Research reviews developments in operational research (OR) and includes numerical examples to illustrate techniques and applications. Topics covered include some of the most widely used OR ""techniques"", such as mathematical programming and simulation, together with the contribution of OR methodology to specific application areas, such as capital investment appraisal and purchasing. This book is comprised of seven chapters and begins with an introduction to the state of mathematical programming systems, along with the relevance of other optimization algorithms to OR and techniques for handling certain types of nonlinearity. The discussion then turns to network optimization techniques and their applications for the New Zealand Justice Department as well as for the wheat and dairy industries. The following chapters focus on computer simulation as applied in OR, with emphasis on various approaches to discrete event modeling; application of OR to industrial maintenance and replacement; financial appraisal methods, including discounting methods; and the use of Bayesian decision analysis to decision making. This text concludes by looking at the purchasing function and the limitations of classical stock control theory in practice. Models and procedures are developed to cope with real situations. Materials requirements planning, quantity discounts, price inflation, commodity purchasing decisions, and blending problems are considered. This monograph will be of interest to planners, decision makers, and others involved in operations research.

The systems movement, now 40 years old, is made up of many associations of systems thinkers from different disciplines all over the world. The United Kingdom Systems Society (UKSS) was formed in 1978. Today it has over 300 members and is committed to the development and promotion of "systems" philosophy, theory, concepts and methodolo gies for improving decision making for the benefit of organizations and wider society. The first UKSS International Conference was held at the University of Hull in July ofHuddersfield 1989. Since then we have held International Conferences at the Universities (1991) and Paisley (1993). The UKSS International Conferences are now an established biannual event and this, our fourth international conference, will be jointly hosted by the Universities of Hull and Humberside. Systems science is considered to be a trans-discipline which promotes critical and effective intervention in complex organisational and social problem situations. As such it traverses "hard", through "soft" to "critical" systems thinking and methodologies. Yet, despite the currently robust state of the UKSS the systems movement cannot be described as an international movement: different subdisciplines are at different stages of development and are often engaged in pursuing their own particular interests and themes with little "conversation" between the subdisciplines despite their common interest in systems.

Operational Gaming: An International Approach is the result of research carried out at the International Institute for Applied Systems Analysis (IIASA) situated at Laxenburg (near Vienna), Austria, which relates game theory and system analysis to decision making. The book first shows the relationship of game theory, experimental gaming, and operational gaming through a state-of-the-art survey. This topic includes the history, context, type, and uses of gaming. Then, the text shifts to the discussion on operational gaming, including the definitions of institutional model and game situation concepts. An overview of gaming in different nations including USSR is provided. The book also studies the international transfer of games and the East-West international trade games. The future of this field of study, as well as its implications for humans, is also examined in the latter parts. This book will be of significance to those interested in game theories and those people involved in policy and decision making in their country or organization.

Many agree that the foreign aid system - which today involves virtually every nation on earth - needs drastic change. But there is much conflict as to what should be done. In Aid on the Edge of Chaos, Ben Ramalingam argues that what is most needed is the creative and innovative transformation of how aid works. Foreign aid today is dominated by linear, mechanistic ideas that emerged from early twentieth century industry, and are ill-suited to the world we face today. The problems and systems aid agencies deal with on a daily basis have more in common with ecosystems than machines: they are interconnected, diverse, and dynamic; they cannot be just simply re-engineered or fixed. Outside of aid, social scientists, economists, business leaders, and policy makers have started applying innovative and scientific approaches to such problems, informed by ideas from the 'new science' of complex adaptive systems. Inspired by these efforts, aid practitioners and researchers have started experimenting with such approaches in their own work. This book showcases the experiences, insights, and often remarkable results of innovative thinkers and practitioners who are working to bring these approaches into the mainstream of aid. From transforming child malnutrition to rethinking economic growth, from building peace to reversing desertification, from rural Vietnam to urban Kenya, the ideas of complex systems thinking are starting to be used to make foreign aid more relevant, more appropriate, and more catalytic. Aid on the Edge of Chaos argues that such ideas and approaches should play a vital part of the transformation of aid. Aid should move from being an imperfect post-World War II global resource transfer system, to a new form of global cooperation that is truly fit for the twenty-first century.

This is a research guide and bibliography with citation frequency on the decision support systems research area and its references disciplines. It contains only references that have been cited frequently by more than several thousand authors of decision support systems articles published in a set of carefully selected journals according to objective criteria set forth in a data chapter. Each item in the bibliography of the book contains the citation frequency representing its weight and degree of influence on the decision support systems research. Each item represents objective and unobtrusive judgment of all the authors of major articles published in more than 140 information systems journals during 1970-2001. It will be a useful research guide to the DSS literature.
