In this paper a fuzzy analytical network process model for supporting the vendor selection process in strategic situations is suggested. First, the vendor evaluation problem is putting together by use of the multi-criteria decision-making (MCDM) approach and a five-step hybrid process, which incorporates the technique of fuzzy analytical network process. Then the modified TOPSIS (technique for order performance by similarity to ideal solution) is used to rank vendors in terms of their overall performances. The newly developed ANP will be used to compute the relative weights of the multiple evaluation criteria, which are obtained from the nominal group technique (NGT) with interdependences. To show the ability of the suggested model a case study is proposed. This case study shows how this approach can be used for the strategic vendor selection problem.
