✦ Synopsis

This paper investigates the problems of decision making with multiple judge, multiple criteria in a fuzzy environment, where the performance of alternatives and the importance of criteria are imprecisely defined and represented by fuzzy sets. A fuzzy model associated with the solution algorithm is proposed on the basis of an ~-level weighted, fuzzy preference relation. A numerical example is solved for illustration.

The basic operations of fuzzy sets, such as negation, intersection, and union, usually are computed by applying the one-complement, minimum, and maximum operators to the membership functions of fuzzy sets. However, different decision agents may have different perceptions for these fuzzy operations.
