一种新的基于模糊等式的群体决策方法

A New Method of Group Decision Making Based on Fuzzv Equation

以模糊互补判断矩阵为基础,提出了基于模糊等式的群体决策方法。将模糊等式转化为线性规划模型,通过求解线性规划,得到决策群体关于备选方案集的排序向量,从而对方案进行排序。该方法将传统群体决策的两个步骤,即群体集结与求解排序向量合为一体,简化了计算步骤,并且还适用于具有不完全模糊互补关系的情况,更加符合现实情况。

The method for group decision ma Based on the conplementary judgment matrix, method investigates the prior vector in group dec g t isi based on the fuzzy equation is presentde in this paper. ransferring the fuzzy equation to linear program, the on making problem by solving linear program ,and ranks the alternative according to the prior vector . This method combines the group synthesis and prioritization stages into a coherent integrated framework and can deal with missing judgments,which corresponds to the reality.
