摘要
针对DS组合规则对证据之间冲突度量估计比较"保守"的问题,提出了一种新的证据组合规则。新组合规则充分考虑了证据之间所有可能的冲突,从而使得在组合过程中不一致的信息被抑制,而一致的信息则被放大。与DS组合规则相比,根据新组合规则得到的合成证据收敛性更好,因此更有利于下一步的识别判决。数值实验验证了新组合规则的有效性。
To solve the problem that the DS combination rule gives a conservative estimate to the conflict measure between evidences, a new evidence combination rule is proposed. All the potential conflicts are fully considered in the new cormbination rule, which ensures that the inconsistent information is suppressed and the consistent information is magnified. The combined evidence gotten with the new combination rule has a better convergence characteristic than that gotten with the DS combination rule, which is helpful to the subsequent decision for target identification. Simulation experiments verify the effectiveness of the new combination rule.
