New method for conflict evidence processing in D-S theory

Aiming at there will generate a counter-intuitive conclusion when classical DS evidence theory handle the highly conflict evidence information,this paper introduced the concept of compatibility ratio between conflict evidences based on the evidence support degree,and the concept of evidence credibility ratio,presented a new determine method for evidence weight,using DS evidence theory combination rules for data processing at last.Compared with other existed methods,this paper considered the conflict and consistency,calculated the evidence weight objectively,it was faster in data convergence,the conclusion was more consistent with facts.It made up the deficiency of DS theory and provided a new way for DS evidence theory algorithm improving.
