Abstract: Today, the global market is confronted with short-lifecycle products or highly demanding customers that calls a lot of focus on supply chain. Among the activities of the supply chain, activities of effective purchasing are the most important activity to proper selection of suppliers since of supplier evaluation and selection problem is a multi-criteria decision-making problem that is along with high degree of ambiguity and uncertainty in the real world decision making. Since the information on real world decision-making are often imprecise and expressed verbally therefore the fuzzy sets theory can be effectively used to solve such problems. This paper first provides an overview on the supplier evaluation and selection problem, and then presents a decision making model that integrates interval-valued intuitionistic fuzzy AHP (IVIF-AHP) and interval-valued intuitionistic fuzzy TOPSIS (IVIF-TOPSIS) to solve such problems, and in the end, provides a numerical example to demonstrate the use of the proposed approach.

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