Competition between supply chains of businesses reveals the importance of supplier selection and performance evaluation when the current state of the international markets and the global economy are taken into consideration. As in many other sectors, it is also very important for companies in the textile sector to use their resources more efficiently and constantly evaluate their suppliers in order to compete with their competitors. In this study, the performance of 16 common fiber suppliers of five different companies that are operate in one of subsector of textile sector namely the blanket sector have been measured and evaluated using fuzzy analytic hierarchy process (FAHP) and fuzzy data envelopment analysis (FDEA) methods. Criteria, which are weighted by FAHP method have been selected as the input and output variables to be used in FDEA. The fuzzy efficiency of supplier firms at different cut levels has been measured by FDEA. Efficient and inefficient suppliers have been identified as a result of efficiency measurement. Finally, a general discussion of the findings and directions for future research has been provided.
