An axiomatic approach to robustness in search problems with multiple scenarios
- …This paper is devoted to the the search of robust solutions in state space graphs when costs depend on scenarios. We first present axiomatic requirements for preference compatibility with the intuitive idea of robustness. This leads us to propose the Lorenz dominance rule as a basis for robustness a…

State space search for risk-averse agents
- …We investigate search problems under risk in statespace graphs, with the aim of finding optimal paths for risk-averse agents. We consider problems where uncertainty is due to the existence of different scenarios of known probabilities, with different impacts on costs of solution-paths. We consider v…

Preference-based search in state space graphs
- …The aim of this paper is to introduce a general framework for preference-based search in state space graphs with a focus on the search of the preferred solutions. After introducing a formal definition of preference-based search problems, we introduce the PBA ∗ algorithm, a generalization of the A ∗ …

Collaborative Filtering Methods based on Fuzzy Preference Relations
- …This paper introduces a new approach for decision support. It is characterized by a collaborativedecision making process relying on the implicit sharing of preferences and experience between different individuals facing similar decision problems. A recommendation principle is described, based on fu…

Preference Aggregation with Graphical Utility Models
- …This paper deals with preference representation and aggregation in the context of multiattribute utility theory. We consider a set of alternatives having a combinatorial structure. We assume that preferences are compactly represented by graphical utility models derived from generalized additive deco…

Assessing and evaluating competing projects: the example of Cost-Benefit Analysis
- … Decision-making inevitably implies, at some stage, the allocation of rare resources to some alternatives rather than to others (e.g. deciding how to use one's income). It is therefore not at all surprising that the question of helping a decision-maker to choose between competing alternatives, proj…

Chapter 3 Evaluating multidimensional objects:
- …Introduction 1.1 Motivation We tried to show in Chapter 2 that "voting", although being a familiar activity to almost everyone, raises many important and difficult questions that are closely connected to the subject of this book. Our main objective in this Chapter is similar. We all share the -- m…

Qualitative decision theory: from Savage’s axioms to nonmonotonic reasoning
- …Abstract: This paper investigates to what extent a purely symbolic approach to decision making under uncertainty is possible, in the scope of Artificial Intelligence. Contrary to classical approaches to decision theory, we try to rank acts without resorting to any numerical representation of utility…
