A supplier selection is inherently a multi-criterion decision making problem. It must be systematically considered as it is a decision of strategic importance of companies. Lots of models have been developed to find an optimum solution of this complex and unstructured decision making problem. Fuzzy Analytic Hierarchy Process (Fuzzy AHP), which is a synthetic extension of classical AHP, is one of the best method for deciding among the complex structure at different levels. In this paper an extent analysis of fuzzy analytic hierarchy process (AHP) has been applied to evaluate and select the best supplier firm providing most satisfaction. The evaluation criteria are developed particularly for an apparel manufacturing organization and used successfully in the proposed model. A detailed step-by-step implementation method is presented in this paper and finally the best supplier was selected to prove the validity of the method.
