一种新的基于证据理论的合成公式

A New Combination Rules of Evidence Theory

由于D S证据合成公式所存在的不足 ,使证据理论的应用受到了一定的限制 .Yager对此作了改进 ,但改进后合成公式又存在着新的问题 .鉴于此 ,本文在引入证据可信度概念的基础上 ,提出了一个新的证据合成公式 .新的合成公式弥补了D S证据理论和Yager合成公式所存在的不足 。

D S evidence theory is a very useful tool in dealing with the uncertainty problems,but its application is limited by the shortcomings of combination rules.Yager had provided some the modified rules,but his rules have some deficiencies.So in this article the new combination rules are proposed which are better than D S's and Yager's rules in combining the conflicted evidences.
