New Methods of Evidence Conflict Measurement Based on Conjunctive Combination Rule

Abstract:

In the effective combination of conflicting evidences using the Dempster-Shafer evidence theory, the first step is to reasonably measure the conflict between evidences, but there are limitations in the existing conflict measurement methods. Two new conflict measurement methods based on conjunctive combination rule are put forword, which overcome the limitations of the existing measurement methods. They have four satisfactory properties. Firstly, new methods can measure the total conflict between any pieces of evidence simultaneously, which can satisfy the interchangeability and combinability. Secondly, they overcome the operational problem of the existing binary conflict measurement methods. Thirdly, they are more suitable for people's intuitive logic reasoning. Another, their moderate complexity are easy for project implementation. So new methods have better comprehensive effect under different evidence conditions.
