The New Definition and Measure Method of Distance between Vague Sets

摘要

Distance measure between vague sets is one of the most important technologies in various application fields of vague sets. In this paper, according to the formula of Canberra distance, a necessary condition of the distance measure between vague sets is pointed out, and an improved axiom definition of the distance measure between vague sets is proposed, then a new measure method of the distance between vague sets is introduced, which is proved to satisfy the axiom definition above. Thus the presented methodical deficiency is made up.
