Abstract
This paper proposes an integrated decision making model for supplier evaluation under fuzzy environment. First the fuzzy decision matrix is formed and using fuzzy PROMETHEE the pairwise comparison is performed. Then, by fuzzy linear programming (FLP) the weights of the attributes pairwise matrices are obtained. Finally, the fuzzy output is transformed to crisp one employing fuzzy analytic hierarchy process (FAHP). The applicability and the validity of the proposed method is evaluate in a case study. The results are helpful in business plan and road map of businesses for obtaining competitive advantage and profit maximization.
