摘要: 判断矩阵的一致性条件,是用AHP法进行排序的必要条件。由于专家的主观性,判断矩阵一般不能满足一致性条件。本文利用变精度粗集的依赖度因子,给出了一种判断矩阵的构造方法。这种方法充分利用排序方案因素的原始信息,又综合了多专家的判断。

关键词: 变精度粗集, 一致性, AHP

Abstract: The consistency of judgement matrix is vital for decision in AHP But it is hard to keep the consistency of judgement matrix because they used to be determined by experts In this paper,the dependency factor,a concept in rough set is proposed to construct judgement matrix of AHP The method need not compare factors directly But it utilizes fully the information in schemes and experts’subjective judgment

Key words: Variable precision rough set, consistency, AHP
