Consistency Checking of Fuzzy Evaluation Matrix for Web Quality

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.
