Humphreys@lse. ac. uk This book presents a selection of contributions to the conference on Implementing Systems for Supporting Management Decisions: Concepts, Methods, and Experiences held in London in July, 1996. The conference was organized by the International Federation of Infonnation Processing's Working Group 8. 3 on Decision Support Systems and the London School of Economics and Political Science. (LSE). The Programme Committee for the Conference comprised Liam Bannon, University of Limerick; Patrick Humphreys, LSE, co-chairperson; Andrew McCosh, University of Edinburgh; Piero Migliarese, Politecnico di Milano, co- chairperson; Jean-Charles Pomerol, LAFORIA, Universite Paris VI. The chairperson of the organizing committee was Dina Berkeley, LSE. The programme committee members served also as the editors of this book. Each contribution was selected by the editors after peer review and was developed by its authors specifically for inclusion in this volume. Working group 8.3 was formally established in 1981 on the recommendation ofIFIP's Technical Committee on Information Systems (TC8). The scope of the working group covers: "Development of approaches for applying information systems technology to increase the effectiveness of decision makers in situations where the computer system can support and enhance human judgment in the perfonnance of tasks that have elements that cannot be specified in advance.

This study is devoted exclusively to discrete multicriterion decision making. Typically, multicriterion analysis is used in two distinct frameworks: Firstly, there is multiple criteria linear programming, which is an extension of the results of linear programming and its associated algorithms. Secondly, there is discrete multicriterion decision making, which is concerned with choices among a finite number of possible alternatives such as projects, investments, decisions, and so on. This text concentrates on the basic principles in the domain of discrete multicriterion analysis, and examines each of these principles in terms of their properties and their implications. In multicriterion decision analysis, any optimum in the strict sense of the term does not exist. Rather, multicriterion decision making utilizes tools, methods, and thinking to examine several solutions, each having their advantages and disadvantages, depending on one's point of view. Actually, various methods exist for reaching a good choice in a multicriterion setting and even a complete ranking of the alternatives.The book describes and compares these methods, so-called "aggregation methods", with their advantages and their shortcomings. Clearly, organizations are becoming more complex, and it is becoming harder and harder to disregard complexity of points of view, motivations, and objectives. The day of the single objective (profit, social environment) is over and the wishes of all those involved in all their diversity must be taken into account. To do this, a basic knowledge of multicriterion decision analysis is necessary. The objective of this book is to supply that knowledge and enable it to be applied.

Multicriterion Decision in Management: Principles and Practice is the first multicriterion analysis book devoted exclusively to discrete multicriterion decision making. Typically, multicriterion analysis is used in two distinct frameworks: Firstly, there is multiple criteria linear programming, which is an extension of the results of linear programming and its associated algorithms. Secondly, there is discrete multicriterion decision making, which is concerned with choices among a finite number of possible alternatives such as projects, investments, decisions, etc. This is the focus of this book. The book concentrates on the basic principles in the domain of discrete multicriterion analysis, and examines each of these principles in terms of their properties and their implications. In multicriterion decision analysis, any optimum in the strict sense of the term does not exist.

The book describes and compares these methods, so-called `aggregation methods', with their advantages and their shortcomings. Clearly, organizations are becoming more complex, and it is becoming harder and harder to disregard complexity of points of view, motivations, and objectives. The day of the single objective (profit, social environment, etc. ) is over and the wishes of all those involved in all their diversity must be taken into account. To do this, a basic knowledge of multicriterion decision analysis is necessary. The objective of this book is to supply that knowledge and enable it to be applied. The book is intended for use by practitioners (managers, consultants), researchers, and students in engineering and business.

Developed from presentations given at the Cerisy SVSI (Sciences de la vie, sciences de l’information) conference held in 2016, this book presents a broad overview of thought and research at the intersection of life sciences and information sciences.The contributors to this edited volume explore life and information on an equal footing, with each considered as crucial to the other. In the first part of the book, the relation of life and information in the functioning of genes, at both the phylogenetic and ontogenetic levels, is articulated and the common understanding of DNA as code is problematized from a range of perspectives. The second part of the book homes in on the algorithmic nature of information, questioning the fit between life and automaton and the accompanying division between individualization and invariance.Consisting of both philosophical speculation and ethological research, the explorations in this book are a timely intervention into prevailing understandings of the relation between information and life.

Chance, Calculation and Life brings together 16 original papers from the colloquium of the same name, organized by the International Cultural Center of Cerisy in 2019. From mathematics to the humanities and biology, there are many concepts and questions related to chance. What are the different types of chance? Does chance correspond to a lack of knowledge about the causes of events, or is there a truly intrinsic and irreducible chance? Does chance preside over our decisions? Does it govern evolution? Is it at the origin of life? What part do chance and necessity play in biology? This book answers these fundamental questions by bringing together the clear and richly documented contributions of mathematicians, physicists, biologists and philosophers who make this book an incomparable tool for work and reflection.

Despite uncertainty, people are born to act. Faced with environmental aggression and upheaval, inaction is more stressful than action.What choices, strategies or methods need to be implemented so that action is as effective as possible in terms of the objectives to be achieved? We should not delude ourselves about the term "good decision", which does not have much meaning when we act in an uncertain environment and when we know the weakness of forecasts. However, we must know how to act and be capable of taking the most appropriate action.Action in Uncertainty is a real guide to taking effective action when nothing is certain. According to the different types of uncertainty, what are the respective good uses of expertise and intuition? How do we motivate teams and avoid cognitive bias and manipulation? These themes are dealt with in clear and accessible terms to help decision-makers make the right choices in a world that is more uncertain than ever.

Making a decision, of any importance, is never simple. On the one hand, specialists in decision theory do not come within the reach of most policy makers and, secondly, there are very few books on pragmatic decision that are not purely anecdotal. In addition, there is virtually no book that provides a link between decision-making and action. This book provides a bridge between the latest results in artificial intelligence, neurobiology, psychology and decision-making for action. What is the role of intuition or emotion? What are the main psychological biases of which we must be wary? How can we avoid being manipulated? What is the proper use of planning? How can we remain rational even if one is not an expert in probabilities? Perhaps more importantly for managers, how does one go from decision to action? So many questions fundamental to the practice of decision-making are addressed.This book dissects all issues that arise almost daily for decision-makers, at least for major decisions. Drawing on numerous examples, this book answers, in plain language and imagery, all your questions. The final chapter takes the form of a brief reminder - everything you have to remember to be a good decision-maker.
