| 摘 要： | 为了有效地融合高度冲突的证据,本文在焦元相似度和矛盾焦元的基础上提出了一种新的证据组合规则.该规则综合了Dempster-Shafer证据理论及加性融合两者的优点,首先从焦元冲突程度的角度对证据进行冲突检验,然后对冲突证据进行加性合成,从而消除证据之间的冲突.为了避免计算量过大的现象将焦元分为矛盾焦元和正常焦元两部分....

| Abstract: | 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. |
