模糊多准则决策方法研究综述

Fuzzy multi-criteria decision-making is one of the advanced research direction in decision-making fields and of wide applications in real decision-making. The current research on the multi-criteria linguistic decision-making methods and fuzzy multi-criteria decision-making methods based on fuzzy number, intuitionistic fuzzy set and vague set are reviewed. The definition of intuitionistic trapezoidal fuzzy number and interval intuitionistic trapezoidal fuzzy number are given, which are extended of fuzzy number and intuitionistic fuzzy set. And some problems and future research directions on fuzzy multi-criteria decision-making are also pointed out.
