  Dempster-Shafer theory of evidence (D-S theory) is widely used in uncertain
information process. The basic probability assignment(BPA) is a key element in
D-S theory. How to measure the distance between two BPAs is an open issue. In
this paper, a new method to measure the distance of two BPAs is proposed. The
proposed method is a generalized of existing evidence distance. Numerical
examples are illustrated that the proposed method can overcome the shortcomings
of existing methods.
