Some extensions of fuzzy sets such as interval‐valued fuzzy sets, intuitionistic fuzzy sets, interval‐valued intuitionistic fuzzy sets, type n‐fuzzy sets, and neutrosophic sets provided powerful and practical tools for dealing with uncertainty in decision‐making problems. Neutrosophic set is defined with three‐dimensional membership functions to describe the degrees of truth, indeterminacy, and falsity. Neutrosophic set theory is a useful instrument to handle incomplete, inconsistent, and indeterminate information. In this paper, we first propose a modified score function for ranking single‐valued neutrosophic numbers. Then, we suggest a TOPSIS
