一种新的多属性决策方法

A New Approach of Fuzzy Multi-attribute Decision Making

针对模糊多属性决策问题,提出了一种新的属性值以三角模糊数形式给出的模糊多属性决策方法。首先定义了两三角模糊数的中心决策矩阵;其次通过引入方案间优势度和优势度比较矩阵概念及其计算公式,从而给出了方案的排序,实例分析说明了所提出的决策方法的合理性及其算法的有效性。

For the fuzzy multi-attribute decision making（FMADM） problems,a new FMADM method is proposed in which the attribute values is in the form triangular fuzzy numbers.Firstly,two central judgment matrix of trangular fuzzy numbers are defined.Secondly,the concepts and formulas for predominance strength and predominance comparative matrix between alternatives are introduced,and the alternatives are ranked according to the priority method of fuzzy complementary judgment matrix.An example shows the rationality of decision-making approach and the validity of the algorithm mentioned above.
