Abstract: Supply chain management (SCM) is one of the most important competitive strategies used by modern enterprises. The main aim of supply chain management is to integrate various suppliers to satisfy market demands. To this end, supplier selection and evaluation plays an important role in establishing an effective supply chain. However, it is a hard problem since supplier selection is typically a multi criteria group decision-making problem involving several conflicting criteria on which decision-maker's knowledge is usually vague and imprecise. The current study proposes an AHP method combined with interval intuitionistic fuzzy set to select appropriate supplier in group decision-making environments. A numerical example for supplier selection has been provided to illustrate application of the proposed interval intuitionistic fuzzy AHP method.

Keywords: supplier selection and evaluation; analytic hierarchy process; AHP; interval-valued intuitionistic fuzzy.
