Distance measures of hesitant complex neutrosophic sets and their application in decision-making

This thesis consists of six sections. In Section 1, detailed literature review and motivation of the thesis are presented. In Section 2, definitions of fuzzy set, complex fuzzy set, and some of their generalizations are given with their examples. In Section 3, the concept of hesitant complex neutrosophic sets is introduced a score and accuracy functions for hesitant complex neutrosophic elements are defined. In Section 4, Hamming, Euclidean and Haussdorf distance measures formulas between two hesitant complex neutrosophic sets are defined and some results are obtained. Also, weighted distance measures between two hesitant complex neutrosophic sets are introduced. In Section 5, a multiple criteria decision-making method based on the proposed distance measures is developed and its application in decision making problem is presented. In Section 6, it is made some explanations about the obtained results and works to be planned in the future.
