In view of the problems such as the oversubjective and excessive calculation of fuzzy analytic hierarchy process (FAHP) in the process of selecting suppliers, this paper puts forward the evaluation method of combining fuzzy analytic hierarchy process with the ideal point method by establishing a reasonable evaluation index system for serviceoriented enterprise suppliers, and by using the triangular fuzzy analytic hierarchy process (TFAHP) in the evaluation index system to solve the weight, then uses the ideal point method (TOPSIS) to obtain the standardized matrix and triangular fuzzy analytic hierarchy process of the index weights obtained by the combination of the weighted standardized matrix, and finally obtains the sorted results of the comprehensive capacity of each supplier through the closeness of the ideal point. The results show that this method can effectively reduce the influence of subjective factors on supplier evaluation and reduce its computational difficulty. By practical case analysis, it is verified that the combination of FAHP and TOPSIS can provide a targeted supplier selection strategy for serviceoriented enterprises, which has better practical application value.
