Dempster的合并规则只能适用于独立的证据体。两个证据体之间的依赖性的一种发生是当它们来自共同的来源时。本文提出了一种改进的方法来合并相关的证据体，考虑到共同的信息源的重要性。该方法是基于重要性加权操作和“分解”操作。最后通过一个算例说明了该方法的实用性和有效性。
Dempster’s combination rule can only be applied to independent bodies of evidence. One occurrence of dependence between two bodies of evidence is when they result from a common source. This paper proposes an improved method for combining dependent bodies of evidence which takes the significance of the common information sources into consideration. The method is based on the significance weighting operation and the “decombination” operation. A numerical example is illustrated to show the use and effectiveness of the proposed method.
