When making decisions under uncertainty, the optimal choices are often difficult to discern, especially if not enough information has been gathered. Two key questions in this regard relate to whether one should stop the information gathering process and commit to a decision (stopping criterion), and if not, what information to gather next (selection criterion). The proposed thesis is concerned with addressing this problem in light of a new advance, known as the Same--Decision Probability (SDP), which is the probability that we would make the same decision had we known what we currently do not know. In this thesis, we show how the SDP can be used to be an effective stopping criterion, and compare it to traditional criteria to demonstrate how it provides a fresh perspective in decision making under uncertainty. Additionally, we develop the first exact algorithm to compute the SDP so that it may be used as a stopping criterion. We demonstrate the effectiveness of these algorithms on real and synthetic networks, and show that our proposed stopping criterion can lead to an early stopping of information gathering. Furthermore, we demonstrate that the SDP can be used as a selection criterion. In particular, since there are many criteria for measuring the value of information, each based on optimizing different objectives, we propose a new SDP-based criterion for measuring the value of information --- this criterion values information that leads to robust decisions (i.e., ones that are unlikely to change due to new information). We develop the first algorithm to optimize the value of information, given the SDP as the reward criterion, and show empirical results that prove the utility of this novel criterion. We further answer several questions regarding the computational complexity of the SDP, which is known to be PP^PP-complete. Finally, we present results of applying the SDP as an information gathering criterion in practical problems including tutoring systems (do we need to ask more questions?) and machine learning (do we have enough data?).

How do you approach difficult decisions? Decision making is an integral part of business and technology, as well as almost every other facet of life. Now there is a uniquely practical book that can help you tackle your next decision with confidence. In Making Robust Decisions: Decision Management for Business, Service, and Technical Teams, you will learn: why decision making can be so difficult; how to address the challenges that uncertain, conflicting, incomplete, or evolving information present; and how to achieve robust decisions despite the varied personalities and perspectives on your team. Combining more than ten years of study of decision support, cognitive psychology, product development, and business management with modern Artificial Intelligence concepts, Making Robust Decisions gives you the tools you need to produce optimal decisions—those that make good use of available information, achieve buy-in from all parties, and yield the best possible results. Packed with practical examples and case studies, Making Robust Decisions strikes a middle ground between self-help books that, while interesting in theory, may not help with real-world problems and highly technical analysis texts. It provides some methods you can implement right away and others that you and your organization can grow into. It is readable, useful, and readily applicable to a wide variety of decision-making problems. The methods introduced in Making Robust Decisions can help with such varied issues as selecting a concept, managing a portfolio, choosing a vendor, evaluating a proposal, selecting from architecture options, choosing a design, and determining whether to make or buy an item. They support military selection of the best course of action (COA), Analysis of Alternatives (AoA), and homeland security strategies. Making Robust Decisions includes chapters on making estimates, working with decision teams, framing problems, the influence of belief, and using AccordÔ decision-making software to support robust decisions. It includes decision-making templates and demonstrates how the methods described support Design for Six Sigma practitioners and provide help in un-sticking the OODA Loop. If you’re in the business of making difficult decisions while managing uncertainty, risk, and team conflict, then discover the new, effective techniques presented in Making Robust Decisions.

This open access book focuses on both the theory and practice associated with the tools and approaches for decisionmaking in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process. The book offers guidance in identifying and applying appropriate approaches and tools to design plans, as well as advice on implementing these plans in the real world. For decisionmakers and practitioners, the book includes realistic examples and practical guidelines that should help them understand what decisionmaking under deep uncertainty is and how it may be of assistance to them. Decision Making under Deep Uncertainty: From Theory to Practice is divided into four parts. Part I presents five approaches for designing strategic plans under deep uncertainty: Robust Decision Making, Dynamic Adaptive Planning, Dynamic Adaptive Policy Pathways, Info-Gap Decision Theory, and Engineering Options Analysis. Each approach is worked out in terms of its theoretical foundations, methodological steps to follow when using the approach, latest methodological insights, and challenges for improvement. In Part II, applications of each of these approaches are presented. Based on recent case studies, the practical implications of applying each approach are discussed in depth. Part III focuses on using the approaches and tools in real-world contexts, based on insights from real-world cases. Part IV contains conclusions and a synthesis of the lessons that can be drawn for designing, applying, and implementing strategic plans under deep uncertainty, as well as recommendations for future work. The publication of this book has been funded by the Radboud University, the RAND Corporation, Delft University of Technology, and Deltares.

What Is Decision Analysis The term "decision analysis" (DA) refers to the academic field that encompasses the theory, technique, and professional practice that are required to tackle significant decisions in an organized fashion. It is possible to prescribe a recommended course of action by applying the maximum expected-utility axiom to a well-formed representation of the decision. Additionally, decision analysis includes many procedures, methods, and tools for translating the formal representation of a decision and its corresponding recommendation into insight for the decision maker, as well as for other corporate and non-corporate stakeholders. How You Will Benefit (I) Insights, and validations about the following topics: Chapter 1: Decision Analysis Chapter 2: Decision Theory Chapter 3: Multiple-criteria Decision Analysis Chapter 4: Expected Value of Sample Information Chapter 5: Decision-making Software Chapter 6: Robust Decision-making Chapter 7: Expected Value of Including Uncertainty Chapter 8: Decision Quality Chapter 9: Value Tree Analysis Chapter 10: Bayesian Inference in Marketing (II) Answering the public top questions about decision analysis.

Everyone makes decisions, but not everyone is a decision analyst. A decision analyst uses quantitative models and computational methods to formulate decision algorithms, assess decision performance, identify and evaluate options, determine trade-offs and risks, evaluate strategies for investigation, and so on. Info-Gap Decision Theory is written for decision analysts. The term "decision analyst" covers an extremely broad range of practitioners. Virtually all engineers involved in design (of buildings, machines, processes, etc.) or analysis (of safety, reliability, feasibility, etc.) are decision analysts, usually without calling themselves by this name. In addition to engineers, decision analysts work in planning offices for public agencies, in project management consultancies, they are engaged in manufacturing process planning and control, in financial planning and economic analysis, in decision support for medical or technological diagnosis, and so on and on. Decision analysts provide quantitative support for the decision-making process in all areas where systematic decisions are made. This second edition entails changes of several sorts. First, info-gap theory has found application in several new areas - especially biological conservation, economic policy formulation, preparedness against terrorism, and medical decision-making. Pertinent new examples have been included. Second, the combination of info-gap analysis with probabilistic decision algorithms has found wide application. Consequently "hybrid" models of uncertainty, which were treated exclusively in a separate chapter in the previous edition, now appear throughout the book as well as in a separate chapter. Finally, info-gap explanations of robust-satisficing behavior, and especially the Ellsberg and Allais "paradoxes", are discussed in a new chapter together with a theorem indicating when robust-satisficing will have greater probability of success than direct optimizing with uncertain models. New theory developed systematically Many examples from diverse disciplines Realistic representation of severe uncertainty Multi-faceted approach to risk Quantitative model-based decision theory

Human decision making involves problems which are being studied with increasing interest and sophistication. They range from controversial political decisions via individual consumer decisions to such simple tasks as signal discriminations. Although it would seem that decisions have to do with choices among available actions of any kind, there is general agreement that decision making research should pertain to choice prob lems which cannot be solved without a predecisional stage of finding choice alternatives, weighing evidence, and judging values. The ultimate objective of scientific research on decision making is two-fold: (a) to develop a theoretically sound technology for the optimal solution of decision problems, and (b) to formulate a descriptive theory of human decision making. The latter may, in tum, protect decision makers from being caught in the traps of their own limitations and biases. Recently, in decision making research the strong emphasis on well defined laboratory tasks is decreasing in favour of more realistic studies in various practical settings. This may well have been caused by a growing awareness of the fact that decision-behaviour is strongly determined by situational factors, which makes it necessary to look into processes of interaction between the decision maker and the relevant task environ ment. Almost inevitably there is a parallel shift of interest towards problems of utility measurement and the evaluation of consequences.

This book addresses an intriguing question: are our decisions rational? It explains seemingly irrational human decision-making behavior by taking into account our limited ability to process information. It also shows with several examples that optimization under granularity restriction leads to observed human decision-making. Drawing on the Nobel-prize-winning studies by Kahneman and Tversky, researchers have found many examples of seemingly irrational decisions: e.g., we overestimate the probability of rare events. Our explanation is that since human abilities to process information are limited, we operate not with the exact values of relevant quantities, but with “granules” that contain these values. We show that optimization under such granularity indeed leads to observed human behavior. In particular, for the first time, we explain the mysterious empirical dependence of betting odds on actual probabilities. This book can be recommended to all students interested in human decision-making, to researchers whose work involves human decisions, and to practitioners who design and employ systems involving human decision-making —so that they can better utilize our ability to make decisions under uncertainty.
