Combination rule based on support of the focal elements
基于焦元支持度的合成规则

To combine highly conflicting evidences efficiently, a new evidence combination rule based on the similarity of focal elements and the conflicting focal element is proposed. This combination rule utilizes the advantages of the Dempster-Shafer(D-S) evidence theory and the additive strategy. The conflicting evidence is first verified according to the extent of the focal element, and then, modified by the additive strategy. The focal elements are divided into normal focal elements and conflicting focal elements to mitigate the huge calculation. Compared with D-S combination rule and other methods by simulation, the new combination rule exhibits the ability in combining highly conflicting evidences rationally, and avoiding one-vote negation with good robustness.
