A proper supplier selection supports a company's long-term strategies and its competitive position. Due to presence of ambiguities and uncertainties in the decision making process for selecting suppliers, fuzzy techniques could provide more reliable and flexible decision of supplier selection problem. In such techniques, customer needs and engineering requirements are weighted by the method of fuzzy analytic network process (ANP) and relationship matrix of quality function deployment (QFD) in fuzzy environment of their importance degree, respectively. Using a mathematical model would integrate the amount of cost components and objective factor measure (OFM). The integrated method is applied to a case study in a reputable Iranian automotive company. The results show the efficiency of the method through considering the viewpoint of decision-makers and their dependence on each other.
