Fuzzy preference relations in group decision making. (English) Zbl 0652.90010
Non-conventional preference relations in decision making, Lect. Notes Econ. Math. Syst. 301, 54-71 (1988).
[For the entire collection see Zbl 0642.00025.]
This paper is devoted to fuzzy preference relations and their applications in group decision making. The author presents the concept of fuzzy preference relations and their fundamental properties. He divides fuzzy preference relations into two classes: direct approach and indirect approach. In the direct approach, a solution is derived directly from a set of individual fuzzy preference relations, and in the indirect approach, a solution is obtained through a group fuzzy preference relation aggregated from individual fuzzy preference relations.
