基于模糊语言的多属性联系数决策方法

A Method of Multi-attribute Connection Number Decision Making Based on Fuzzy Linguistic

针对属性权重已知,属性值以模糊语言给出的多属性决策问题,提出了一种基于模糊语言标度的区间数表示形式,并利用集对分析方法将区间数进行转化为联系数的表示方式,通过联系数中同、异、反的关系,给出相应集势值,由集势值的大小进行择优排序.最后,通过实例分析,验证了该方法的可行性和有效性.

The multi-attribute connection number decision making problem is investigated, in which the attribute weights is known and the attribute values is given in the forms of fuzzy linguistic. A scale of the fuzzy linguistic of interval number is proposed, by identical discrepancy contrary of connection number corresponding values of set is given and ranked by using the values of set. Finally, an example is given, and the result proves the feasibility and efficiency of the proposed method.
