Fuzzy information representation for decision aiding

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