Multiperson Logistics Vendor Selection with Fuzzy Analytic Hierarchical Process Method

Abstract

Based on the fuzzy set theory, a multiperson fuzzy analytic hierarchical process method for the vendor selection is proposed. Firstly, the upper level criteria weights are formed by integrating the fuzzy Delphi method with the eigenvector method. Secondly, the lower level criteria weights and the appropriateness values of each alternative are presented with fuzzy linguistic variables, and the overall evaluation of each alternative can be gotten with hierarchical aggregation methods. Finally, the fuzzy evaluation values are ranked with area compensation method, and the optimal alternative can be selected. A numerical example shows the process of the approach.
