A multicriteria supplier selection framework with interval - valued intuitionistic fuzzy assessment

Abstract

This paper proposes a multicriteria decision making (MCDM) framework for supplier selection under the interval - valued intuitionistic fuzzy environment. In this MCDM problem, the decision-maker (DM) selects the best supplier by ranking alternative suppliers. This ranking is based on the suppliers' performance on and assigned weights to the criteria. The proposed model uses intuitionistic fuzzy assessment as input data and transforms them to an aggregated index, there by ranking the suppliers. A numerical example is developed to illustrate the method.
