Fuzzy Utilities Comparison in Multicriteria Analysis
This paper presents a new approach for comparing fuzzy utilities in fuzzy multicriteria analysis. The approach developed combines the merit of two prominent concepts individually used in the existing methods: the fuzzy reference set and the degree of dominance. The decisive information of the fuzzy utilities being compared is sensibly used. The computation involved is simple, and the underlying concepts are logically sound and comprehensible. The comparative study conducted on benchmark cases in the literature shows that the approach compares favorably with other methods examined.
