A distance measure between intuitionistic fuzzy belief functions

摘要: Intuitionistic fuzzy (IF) evidence theory, as an extension of Dempster-Shafer theory to the intuitionistic environment, is exploited process imprecise and vague information. Since its inception, much interest has been concentrated on IF theory. Many works belief functions in information systems have appeared. However, there little research distance measure between despite fact that classical received close attention. In this paper we mainly investigated based Euclidean two column vectors. The similarity focal elements also taken into account. measures sets are firstly. A new along with properties proofs proposed. positive definiteness matrix guarantee metric measure. Then a It proved proposed distance. As illustrated by examples, sensitive change elements. Moreover, applicability for demonstrated.
