<正> 一、一致性指标μ与相对误差δ_(ij)的分布关系 在层次分析法中,关于判断矩阵的一致性指标μ有如下定理:若正互反矩阵A=(α_(ij))_(n×n)最大特征根对应的正特征向量W=[w_1,w_2,…,w_n]~T,α_(ij)=W_i/W_jε_(ij),ε_(ij)>0。
This paper states the relation between the distribution of relative error conparison judgement and the scale in the AHP and also describes the relation between oconsistency index and variance of reletive error, and the reletion between consistency index and limit of error. So that we find a new method synthelic test for error level of judgement matrix and consistency degree.
