基于模糊互补判断矩阵的一致性调整新方法

Method for Identifying and Improving the Consistency of Fuzzy Complementary Judgment Matrix

针对模糊互补判断矩阵的乘性一致性问题,本文从模糊乘性一致矩阵的定义出发,首先给出了一种衡量判断矩阵一致性程度的新指标,然后综合利用专家给出的直接判断信息和间接判断信息,提出了一种改善模糊互补判断矩阵一致性的新方法,最后通过一个算例说明了此方法的可行性和简洁性。

Focusing on the problem with the fuzzy complementary judgment matrices＇ consistency,based on the multiplicative consistency definition of the complementary judgment matrix,the paper not only gives a method for identifying the consistency of the fuzzy judgment matrix,but also proposes an approach for improving the consistency of the fuzzy judgment matrix by utilizing the direct information and indirect information given by the expert.Finally,a numerical example is given to illustrate the use of the new method.
