模糊信息的熵权多属性决策方案评估方法

Evaluation method of the multi-attribute scheme based on entropy weight of fuzzy information

针对方案评估中属性信息的模糊特性,提出了一种基于模糊信息的熵权多属性方案评估方法。该方法在只有模糊判断矩阵而没有专家权重的情况下,通过模糊评价矩阵的熵以及被评对象到理想点的三角模糊数距离及贴近度,对多个合理方案进行优选评估,得出了可信度较高的优选方案。最后通过实例证明了该方法的有效性。

Aimed at the fuzziness of the scheme evaluation, a new method based on entropy weight of fuzzy information is presented. According to fuzzy rating matrix, approximation degree and distance of triangular fuzzy number to the ideal points, reasonable schemes are evaluated and the most optimal scheme is selected with only fuzzy judging matrix but without experts＇ weights. At last, an example proves the validity of this method.
