Abstract: In real-world supply chain problems because of the non-existence of exact information and various fluctuating conditions, resilient supplier selection problems (RSSPs) are considered. In this paper, interval type-2 fuzzy sets (IT2FSs) are used in a modified VIKOR method to achieve more accuracy in the results. Moreover, a new method for computing weights of decision makers and a new method for computing weight of each evaluation criterion based on subjective and objective data are introduced. Finally, to verify the presented method a numerical example from the existing literature is presented and solved.
