Multi-Criteria Supplier Selection Based on Fuzzy Pairwise Comparison in AHP

Abstract

Supplier selection process has become an important force that influences the management ofindustrial relations. Therefore, it has a great importance for companies. Supplier selectionprocess is a complex multi criteria decision making process where problems include multipleobjects. In this study, multi criteria decision making problems, decision makers’ opinions onthese problems, and the solution processes are discussed. The proposed algorithm, modeledwith trapezoidal fuzzy numbers, is applied to an example in the literature. The results obtainedfrom the proposed algorithm and from the existing method are compared in terms of the qualityof the solution.
