When linguistic evaluations are used in the decision matrix instead of exact numerical values, fuzzy set theory can capture the vagueness in the linguistic evaluations. Ordinary fuzzy sets have been extended to many new types of fuzzy sets such as intuitionistic fuzzy sets, neutrosophic sets, and picture fuzzy sets. Spherical fuzzy sets is an extension of picture fuzzy sets whose squared sum of their parameters is at most equal to one. This paper develops spherical fuzzy CRiteria Importance Through Intercriteria Correlation (CRITIC) method for prioritizing supplier selection criteria. Supplier selection is one of the most critical aspects of any organization since any mistake in this process may cause poor supplier performance and inefficiencies in the business processes. Supplier selection is a multi-criteria decision making problem involving several conflicting criteria and alternatives. A numerical illustration of the proposed method is also given.
