Under many conditions, exact data are inadequate to model real-life situation and fuzzy logic can be incorporated to handle the vagueness of the decision makers. Fuzzy analytic hierarchy process (fuzzy AHP) and fuzzy technique for order performance by similarity to ideal solution (fuzzy TOPSIS) are widely used for tackling multi-criteria decision making (MCDM) problems in real situations for these reasons. Some researches that incorporate the different decision making methods have been introduced in order to compensate the weights among criterion. This paper first presents a hybrid multi-criteria decision making procedure using fuzzy AHP and fuzzy TOPSIS. This proposed procedure is used to solve the supplier selection problem to investigate the applicability of procedure. More specifically, the fuzzy decision matrix is identified by fuzzy TOPSIS and then fuzzy AHP is employed to obtain the crisp values for each alternative to make the final decision. To demonstrate the applicability of the proposed approach, an illustrative example for supplier selection problem is presented and the results are analyzed by comparison of the proposed approach and fuzzy TOPSIS.
