In order to efficiently combine conflict evidences,a new creditability function method was proposed.For getting the evidence-based weight distribution,an evidence creditability function was in- troduced to estimate the weight distribution of the bodies of evidence.Then,the final weight distribu- tion got through the composed method proposed for combining the weights of foregone and evidence- based.Finally,weightedly averaging the existing evidences,the Dempster- sharer combination rule was used to realize information fusion.Comparing with other approaches,the approach above mentioned considers more factors and has stronger practicability.It can be found from examples presented that the approach proposed can recognize the target faster and more efficiently than others.
