Indicators and their weights are the core of the construction of evaluation system. Rational determination of weights requires comprehensive qualitative and quantitative analysis of indicators. Based on Fuzzy Analytic Hierarchy Process, through the comparison of index on every layer, constructing fuzzy complementary judgment matrix on the basis of Triangular fuzzy number, through the formula of weight calculate for complementary judgment matrix, get the weight vector of index on every layer. Compared with the traditional weight determination method, it combines qualitative and quantitative methods, avoids the subjectivity and limitations of decision makers.
