Abstract：An improved measure of similarity based on the Hamming distance for measuring the degree of similarity between intuitionistic fuzzy rough sets was proposed on the basis of analyzing the deficiency of the existing similarity measure method. This method solved the problem of inaccurate similarity measure by adding the hesitancy degree and weight. Firstly, a similarity measure method for the degree of similarity between two intuitionistic fuzzy rough elements was given, and several important characters of it were revealed. Furthermore, a similarity measure method based on the Hamming distance for the degree of similarity between intuitionistic fuzzy rough sets was presented. This method was proved to have the same characters. At last, this improved similarity measure method is confirmed to be more reasonable and effective by examples.
