Analysis and Improvement of Combination Rule in D-S Theory

Abstract

In this paper, the evidence combination principle of Dempster-Shafer (D-S) evidence theory is analyzed in detail. And the method of evidence combination is improved because of the deficiency of D-S evidence theory. Considering the principle“the minority should be subordinate to the majority”, based on Yager’s rule, we put forward a new effective combination rule which works more reasonably.
