Abstract:

The rapid changes that occur nowadays increase the uncertainties around companies and make the decision process harder. The problems encountered in real life predominantly have complex structures and depend on multiple criteria and alternatives. For that reason, fuzzy and multiple-criteria decision making methods are gaining importance. The aim of this study is to help a textile company, which produces shirt-making fabric, choose the most suitable yarn supplier from a number of alternatives. To solve the company’s problem in choosing the right supplier, the fuzzy TOPSIS method was proposed in order to handle the linguistic variables used by the decision makers. In the study, the criteria determined by the decision makers were taken into consideration and three suppliers were evaluated to identify the most suitable one.
