基于可信因子的证据源修正方法

Method to modify evidence source based on trustworthy factors

针对高冲突证据在组合过程中产生冲突悖论、一票否决的问题,提出一种基于可信因子的证据源修正方法。首先通过对多源证据的一致性处理,实现冲突证据的判断与修正;接着分析证据源的可靠性和不确定度,在此基础上给出可信因子定义;最后利用可信因子对证据源进行可信运算。对比实验表明,该方法能有效地解决冲突证据组合问题,得到合理的结果。

Aiming at paradoxes generated in combination of highly conflict evidences, a method based on trustworthy factors to modify the evidence source is proposed. Firstly, the consistency among multi-source evidences is checked, and the conflict evidence is recognized and modified. Then, the reliability and uncertainty of evidences are analyzed, and the definition of trustworthy factors is given based on them. Finally, trustworthy factors are used to modify the evidences. Comparative experiments show that the proposed method can deal with the combination problem of conflic evidences effectively, and the results are reasonable.
