Improved interval valued dual hesitant fuzzy set distance measure and its application

In view of the limitations of distance measure of interval valued dual hesitant fuzzy sets, the axiomatic definition of distance measure of interval valued dual hesitant fuzzy sets is given, and the formula of distance measure of interval valued dual hesitant fuzzy sets based on the deviation of hesitancy degree and the complete deviation of membership degree and non-membership degree is given. The improved distance measure is measured from three information dimensions, more comprehensively and objectively reflects the data information, and makes up for the shortcomings of the traditional distance measure which needs to subjectively expand the data. Finally, a numerical example is given to verify the effectiveness and rationality of the improved distance measure.
