A REPRESENTATIVE METHOD OF SOLUTION OF GROUP DECISION MAKING UNDER FUZZY PREFE RENCES RELATION AND FUZZY LINGUISTIC MAJORITY

Ｋａｃｐｒｚｙｋ（１９８６）在模糊偏好关系和模糊大多数下，利用计算一个基于模糊逻辑的语言变量命题的真实度的方法，给出了几种群决策的解的概念与表示方法。本文在此基础上，引入余核概念，给出了一种在模糊大多数下，兼顾少数个体偏好的群决策的解的概念及其表示方法．

By using true degre method of caculating a linguistic quahtifier proposition based on fuzzy logic, Kacprzyk(1986) gave several kinds of solution concept and representative method of the group deeision making under fuzzy preference relation and fuzzy linguistic majority, . In this paper, by using co core concept and considering individual preferences,author givs a concept of solutions and its representative method for group decision making under fuzzy majority.
