D-S证据合成规则在遇到冲突证据时常有悖常理.针对现有规则的不足,通过理论分析和对几种常用组合规则的比较,提出一种基于近邻思想的冲突证据修正规则,综合考虑证据源的有效性和证据源间的距离,进行信息融合.实验结果表明,该规则对合理的合成方向具有较快的收敛速度,在证据源完全冲突的情况下也能适用.
D-S證據閤成規則在遇到遲突證據時常有悖常理.針對現有規則的不足,通過理論分析和對幾種常用組閤規則的比較,提齣一種基于近鄰思想的遲突證據脩正規則,綜閤攷慮證據源的有效性和證據源間的距離,進行信息融閤.實驗結果錶明,該規則對閤理的閤成方嚮具有較快的收斂速度,在證據源完全遲突的情況下也能適用.

According to the insufficiencies existing in D-S evidence theory when they deal with the conflicting evidences, many scholars present modified rules based on reallocation of the basic probability assigned to conflict. On the base of analyzing and comparing a few common combination rules, a new combination rule is presented to mend the disadvantages of the rules. This new rule realizes information fusion rationally with the use of effectiveness of evidential sources and the distance between them. Experimental results show that the new combination rule overcomes the insufficiencies. The outputs are constringent on the aspect of rationality, and the rule can be applied to combine the total conflict function.
