| 摘 要： | 具有不同特性的证据源，利用现有的冲突度量方法得到的冲突值存在效果不理想的情形。因此，针对现有的冲突度量方法进行分析研究，采用将冲突度量方法两两组合的思想，提出了一类冲突度量方法。利用实例分析几种常用冲突度量方法的特性；描述组合度量方法的实现思路，对组合度量方法中证据理论的适用范围进行讨论。算例结果表明，新方法能够更加有效地判断证据源间的冲突程度，从而使证据融合过程中证据理论的选择更加准确。

| Abstract: | If there are different characteristics for the evidence sources, conflict values to be calculated by using the existing conflict measurement methods have some cases that the effect is not good. Therefore, some methods available are studied and analyzed. The idea to combine these methods two by two is used and one type of conflict measurement method is presented. Some examples are used to analyze the characters of some existing conflict measurement methods. The implementing style of the combination of conflict measurement method is described and its applicable ranges are discussed. Numerical examples show that the proposed method can obtain the conflict value more effectively among evidence sources and make the choice of evidence theory more accurate. |
