Abstract:A new method based on AHP and Delphi method to select spare parts of power enterprises is proposed.Firstly,several experts analyze important factors of materials and then give the comparison matrix.In the process of the weight solution,differences of various experts' determine matrix is integrated by the Delphi method and weight of factors is obtained by the AHP.Then,materials are sorted to form an orderly candidate set of spare parts based on the results of weight.Test result verifies the feasibility of this method.
