摘要
对层次分析法中当专家判断矩阵不一致时如何提取专家信息的方法作了详细探讨 ,主要思想是从原判断矩阵 (n×n) 中找出n- 1个元素 ,这n- 1个元素能够构造出与原专家判断矩阵最为贴近的完全一致的矩阵。由于这样的元素组合很多 ,我们通过程序来完成对所需元素组合的搜索。
In this paper, we discuss in detail the method of distilling expert information from an inconsistent expert judgement matrix, which is used as a calculating tool in AHP (analytic hierarchy process). The main idea is that we can always find out a specific combination of n-1 elements from the inconsistent matrix that is thought to be mostly accurate, to construct a brand new matrix, which is completely consistent and has the most similarity to the original one. A computer program is used to locate such a combination. Finally, we demonstrate the method with an example.
