Abstract:

Under the integrated considerations about  the possibilistic mean and the ideal points, the fuzzy numbers are mapped to the possibilistic interval by a  αcut. In order to form a synthesized index for ranking fuzzy numbers, the  distances between the possibilistic mean and the ideal point are calculated.

 

Key words: ranking fuzzy numbers; the ideal point; the possibilistic mean
