Similarity measure of interval valued intuitionistic fuzzy soft sets of root type in decision making

In this paper we introduce two topological operators on interval valued intuitionistic fuzzy soft set of root type and establish some theoretical properties of these operators. We define Hamming distance between interval valued intuitionistic fuzzy soft sets of root type and establish that it is a metric. Further we define a similarity measure based on interval valued intuitionistic fuzzy soft set of root type and also develop a new decision making method based on this similarity measure between interval valued intuitionistic fuzzy soft sets of root type using Hamming distance. Finally, we provide a numerical example to illustrate the working of this algorithm
