Özet:

Several studies have addressed subcontractor selection problem to date. However, most of them considered subcontractor selection in construction industry and other fields have been disregarded. In order to fill this gap, this study focuses on selecting the best subcontractor under fuzzy environment for a Turkish textile company. The case problem is considered as a multiple criteria decision making (MCDM) problem and a robust hybrid methodology combining Fuzzy Preferences Programming (FPP) Method and Graph Theoretical Matrix Approach (GTMA) is proposed for the solution. In the application, the FPP is used to model the interrelations and interdependences among attributes and the GTMA is utilized to choose the best subcontractor for the company under consideration. The obtained results reveal that the devised methodology can successfully tackle with any type of MCDM problems as well as subcontractor selection.
