Ambiguity and Vagueness of Fuzzy Measure Weight and Fuzzy Reciprocal Data AHP

Abstract

AHP (Analytic Hierarchy Process) has been widely used in decision making. However, it is very difficult to make exact relative importance and to keep their independency structure. Therefore, there are extension methods, non-additive fuzzy measure weight AHP and fuzzy reciprocal data AHP. In this research, we make a comparative consideration between these two methods from a view point of their ambiguity and vagueness.
