摘要： 利用模糊层次分析法(FAHP)评测Web资源质量时，模糊逻辑的引入使成对比较矩阵的一致性判别成为难点。为此，设计最大隶属度元素值替代法，分析并改进基于最小二乘法的一致性判定法。依据判别结果对不一致的模糊矩阵进行修正，直到所有模糊矩阵都满足一致性阈值。分析结果表明，2种方法均能保证Web资源质量评测过程的合理性和结果的可靠性，且后者适用性更高。

Abstract: Checking the consistency of the decision matrixes is essential but becomes very difficult in a Fuzzy Analytic Hierarchy Process(FAHP)-based Web quality assessment due to the fuzzy logic. Two approaches are analyzed in the paper, which are the value substitution with maximum degree of membership and the least-squares-method-based consistency checking. The fuzzy pair-wise comparison matrix meets the consistency requirements by applying the two methods based on key quality data. The study indicates that two techniques can simplify the discrimination of the consistency of fuzzy pair-wise comparison matrixes and ensure the rationality of the assessment and the soundness of decision result. The latter approach is more applicable.
