Abstract

In this paper we consider models which are commonly proposed for decision-aid or negotiation-aid. By means of one or several criteria, they always bring preference relations between objects or actions into play. In practice, it is generally difficult to assess, in a significant way, such preference relations because there are many kinds of imprecision, uncertainty and inaccurate determination. The purpose of this paper is to analyze the main sources of such difficulties and to arrive at an understanding of why the consideration of several criteria may help alleviate these difficulties.
