Özet

Numerous distinct attributes considered for supplier selection such as delivery, reliability, and experience exhibit vagueness and imprecision. Fuzzy set theory appears as an essential tool to provide a decision framework that incorporates imprecise judgments inherent in the supplier selection process. This paper aims to develop a fuzzy multi criteria group decision making technique that makes use of the quality function deployment (QFD) methodology for supplier evaluation and selection. The proposed decision framework initially identifies the features that the purchased product should possess to meet the company's requirements, and then it seeks to determine the relevant supplier assessment criteria while also considering the impacts of inner dependence among them. A house of quality (HOQ) matrix, which translates purchased product features into supplier assessment criteria, is built to determine the desired levels of supplier assessment criteria. Finally, supplier alternatives are ranked by a distance based method. The application of the developed methodology is demonstrated through a case study for evaluation of medical suppliers.
