| Résumé : | This paper studies how an overall fuzzy preference relation can be constructed in the compensatory context of the 'simple additive difference model', when imprecision on the trade-offs has to be taken into account. Three credibility indices of preferences are analysed and illustrated by a numerical example. Arguments are presented supporting the use of the third index, for which an interesting transitivity property (which was an open problem) is proved. © 1995 Kluwer Academic Publishers. |
