| 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. |
