An integrated approach to supplier selection using AHP and FUZZY PROMETHEE

Abstract

Supplier selection has become an important decision problem due to today’s competitive environment. The company gets a competitive advantage in long-term relationships with the right suppliers. In the evaluation process both quantitative and qualitative multiple conflicting criteria should be utilized. This requires a systematic multicriteria decision-making approach to evaluation process. Due to uncertainty in the process and verbal assessment of the decision maker’s fuzzy sets are used. In this study, supplier selection carried out via the integrated use of the multi criteria decision making methods, AHP and the Fuzzy-PROMETHEE. Thus, the advantages of both methods were used. Criteria, weighted using AHP, and evaluation of suppliers are carried out by using Fuzzy PROMETHEE. The method is implemented in a company producing medical devices in Ankara. As a result, the most suitable supplier identified for the company
