| Résumé : | Before the advent of multicriteria analysis, decision problems often took the form of the optimization of an objective function or a utility function. This approach has the advantage of resulting in well-defined mathematical problems but is not always representative of reality: in fact the comparison of several possible decisions is rarely made according to a single point of view and the preferences on a point of view are in many cases only modelled with difficulty by a function. The aim of this paper is to survey the different directions in which multicriteria analysis has developed: multiattribute utility theory, outranking relations, interactive methods. The methodology recently proposed by B. Roy is also presented. © 1981. |
