Fuzzy information representation for decision aiding

Abstract

In this paper we want to stress the relevance of decision aid procedures in complex decision making problems
and claim for an extra effort in order to develop appropriate representation tools when fuzzy criteria
or objectives are present. In particular, we point out how some painting algorithms may help decision makers
to understand problems subject to fuzziness based upon a graphical first approach, like Statistics use to do. Moreover, we point out that although the standard communication tool with machines are either data or
words, we should also consider certain families of graphics for such a role, mainly for the output.
