Résumé en anglais

Conjoint measurement [KRA 71, WAK 89] is concerned with the study of binary relations defined on Cartesian products of sets. Such relations are central in many disciplines, for example:– multicriteria or multiattribute decision making, in which the preference of the decision maker is a relation that encodes, for each pair of alternatives, the preferred option taking into account all criteria [BEL 01, KEE 76, WIN 86];– decision under uncertainty, where the preference relation compares alternatives evaluated on several states of nature [FIS 88, GUL 92, SHA 79, WAK 84, WAK89];– consumer theory, dealing with preference relations that compare bundles of goods [DEB 59];– inter-temporal decision making, that uses preference relations for comparing alternatives evaluated at various instants in time [KOO 60, KOO 72, KEE 76]; and– inequality measurement, that compares distributions of wealth across individuals [ATK 70, BEN 94, BEN 97]
