【摘要】 提出了一种修正的DS证据融合策略,以解决证据冲突情况下的融合问题,该方法综合利用了传统DS证据理论方法所具有的收敛性好及加性融合方法所具有的可靠性高两方面的优点。该方法先对DS证据理论的结果与加性策略结果之间的一致性做出判断,如果一致性好,则采用DS证据理论的结果作为最终结果,这样就保证了算法收敛性,否则,用加性策略的结果对DS证据理论的结果进行修正,从而保证算法的可靠性。该方法在解决冲突证据的合成问题方面体现出良好的适应能力。更多还原

【Abstract】 A modified DS evidence combination method is proposed to solve the problem of combining evidences with high degree of conflict. Such a method comprehensively utilize the advantages of DS theory and additive strategy. First the result of DS theory and additive strategy are compared, then if they are consistent with each other, the result of DS theory will be chosen to guarantee the algorithm’s convergence ability, otherwise the result of DS theory will be modified by the result of additive strategy to guarantee the algorithm’s dependability.更多还原
