针对多种假设应用于同一结论时的不确定性推理问题,提出了一种新的综合置信度
计算方法。该方法直接对各假设的置信度进行合成,避免了证据理论中的概率分配以及
归一化过程。数值分析表明,该方法计算的综合置信度不受各假设参与运算的顺序影响,
对高冲突假设的抗干扰能力强,具有较强的鲁棒性,在工程应用中是一种有效的综合置信度

Abstract: |
A new method for computing the conclusion′s synthetical confidence is proposed
for the uncertainty reasoning problem when multihypothesis is applied in the
same conclusion. The method synthesizes the confidences of multihypothesis di
rectly to avoid assigning and normalizing the probability in evidence reasoning
. The numerical analysis shows that the synthetical confidence obtained by the m
ethod has no relation with the operation order of each hypothesis and has
the antijamming ability for high opposite hypothesis, and has a strong robust
ness. The method is an effective way of computing the synthetical confidence in
engineering practice. |
