Distance measures of type-2 single-valued neutrosophicset and their applications in decision making

In this thesis, the concept of type-2 single-valued neutrosophic sets and some operations of them are defined. Some distance measure methods for type-2 single-valued neutrosophic sets are introduced based on Hausdorff, Hamming and Euclidean distances and some properties of them are investigated. Also, a multi-criteria group decision-making method is developed based on TOPSIS approach under the type-2 single-valued neutrosophic environment. Finally, an illustrative example is given in order to show the validity and process of the proposed method.
