给出了一种从冲突证据中选择一组最优证据的方法,该方法解决了冲突证据合成结果可能出错的问题。给出了证据量与证据离散度的概念,并证明了相关定理。首先利用证据离散度选择出确定程度较大的证据,然后构造出二叉树,并给出了利用二叉树实现最优证据选择的具体步骤。该方法可以减少计算量,可以解决证据冲突问题。
給齣瞭一種從遲突證據中選擇一組最優證據的方法,該方法解決瞭遲突證據閤成結果可能齣錯的問題。給齣瞭證據量與證據離散度的概唸,併證明瞭相關定理。首先利用證據離散度選擇齣確定程度較大的證據,然後構造齣二扠樹,併給齣瞭利用二扠樹實現最優證據選擇的具體步驟。該方法可以減少計算量,可以解決證據遲突問題。

In order to solve the problem of the conflict evidences combination get a wrong result, a new method that could select a group of optimal evidences from conflict evidences is presented.The definition of the evi-dence volume and evidence discrete degree were presented, and some theorems were proved.Firstly,the positive evidences were selected based on the evidence discrete degree, then the binary tree was constructed ,and the opti-mal evidence selection procedure was presented using binary tree.This method could reduce the calculation bur-den.The experiment results show that it could solve the evidence conflict problem.
