层次分析法的改进

摘要

在层次分析法中,当成对比较阵不是一致阵的时候,从原成对比较阵出发,结合问题的实际意义,建立新的一致成对比较阵.在这个一致成对比较阵中,包含了决策者的所有判断参数,而且不再需要一致检验就能得到合理的最终决策.%For AHP,a new method to construct a perfectly consistent pair-wise comparison matrix is proposed. This consistent pairwise comparison matrix from a not necessarily consistent matrix is practical, which includes all the judgement preferences of the decision-maker, and doesn't require any test of consistency. And the reasonable decision can be received from this perfectly consistent pairwise comparison matrix.
