Purpose: In working with Interval-valued intuitionistic fuzzy sets according to considering the membership and non-membership function simultaneously, as well as the interval of the data type, we face to a lot of flexibility to allocate data by the decision maker. Comparison between them, as one of the first concepts in the decision-making process, does not seem so simple. For this purpose, in this paper we present an integrated and efficient method and a new way to prioritize interval-valued intuitionistic fuzzy numbers. Then we apply this method to assess the qualitative qualification of contractors.Methodology: Use interval valued intuitionistic fuzzy sets along with multi criteria decision making.Findings: New ranking method of interval valued intuitionistic fuzzy sets is apllied in evaluating operational units. In addition, by giving a practical example while describing the process performance, the output of the work is observed.Originality/Value: A new method is proposed to determine the preference between interval valued intuitionistic fuzzy sets. In addition, an efficiency process is introduced to assess the qualitative qualification of contractors.
