In this paper we propose to apply the concept of L-valued kernels to the problem of constructing a global ranking from a pairwise L-valued outranking relation defined on a set of decision alternatives as encountered in the fuzzy preference modelling context. Our approach is based on a repetitive selection of best and worst candidates from sharpest L-valued or most credible initial and terminal kernels. A practical illustration will concern the global ranking of movies from individual evaluations of a given set of movie critics. [less ▲]

In this report we will present a linear decomposition of a given L- valued binary relation into a set of sub-relations of kernel-dimension one. We will apply this theoretical result to the design of a faster algorithm for computing L-valued kernels on general L-valued simple graphs. [less ▲]

We present, in terms of logic programming, an algorithm for constructing decision rules from an extensional representation of the solutions to a multiple attributes decision problem. The algorithm is based on the decision tree obtained from a hierarchical decomposition of the decision attributes along their discriminatory power of the decision acts. We illustrate our methodological approach with an application to the cognitive categorization of the human colour vision. [less ▲]

In this article we illustrate that Constraint Logic Programming (CLP) systems allow easy expression and solutions of constrained decision problems. CLP solutions for two industrial linear optimization problems are discussed: - a mixed linear multiple criteria selection problem implemented in the linear rational Prolog III solver, and - a linear integer multiple criteria location problem, particularly adapted to the CHIP solver.

In a first Chapter, we present a critical review of the weighted average when facing distributional performance evaluations measured on an essentially qualitative preference scale. In a second Chapter we develop a general typology of qualitative preference scales between between ordinal and cardinal; from non gradual, non metrifyable, partially gradual, gradual, metrifyable, metric extensive to additive, additive-archemidian and measurable scales. The typology is based on the subjective degree of indeterminateness of the numerical representation of the performance contrasts. In a third Chapter we finally define a typology of subjective outranking situations: elementary, intensive or extensive; based on the corresponding underlying type of the preference measurement scale.
