Abstract The main aim of this paper is to introduce a neurosophic subsethood measure for single valued neutrosophic sets. For this purpose, we first introduce a system of axioms for subsethood measure of single valued neutrosophic sets. Then we give a simple subsethood measure based to distance measure. Finally, to show effectiveness of intended subsethood measure, an application is presented in multicriteria decision making problem and the obtained results are discussed. Though having a simple measure for calculation, the subsethood measure presents a new and useful approach to deal with neutrosophic information.
