Visual program application for supplier selection using fuzzy

Abstract

The choice of supplier in the supply chain network is a very important and quick issue for decision makers. When we work in line with these requirements, a multi-criteria decision support system focusing on supplier importance and ordering is being established. The fuzzy analytical hierarchy process (AHP) and fuzzy DEMATEL methods are used in the decision support system. With Fuzzy DEMATEL (Decision-Making Trial and Evaluation Laboratory) method, the criterias required for supplier selection are listed according to the values they affect the system and affect the system. By using the fuzzy DEMATEL method, the criterion of the criterion is defined and the criterion which the decision maker should consider most is determined. Suppliers are ranked for supplier selection through comparison matrices using the fuzzy AHP method. All these methods are applied with the data obtained through the experts and their results are shown. At the last stage of the work, an interface is created by which all these methods can be used, and a visual program, which is a decision support system and a decision support system, is included.
