中文摘要 |
经典证据理论不能有效处理高度冲突的证据, 极大制约了证据理论的应用. 早期的研究主要集中在修改Dempster组合规则或修改数据模型. Liu的研究又为这个方向提出了一个新的问题: 如何有效表示证据之间的冲突? 但是还存在问题: 如何有效地判断冲突的成因? 针对经典证据理论中的冲突系数无法合理度量证据之间的冲突程度, 提出新的证据冲突系数表示模型, 在冲突证据原因流程分析中总结出冲突的成因. 最后用数值算例说明了本文所提出方法的有效性. |
英文摘要 |
The classical Dempster-Shafer evidence theory can not handle highly conflicting evidence efficiently. This drawback greatly limits the application of Dempster-Shafer evidence theory to real systems. The earlier researches mainly focused on improving the Dempster rules of combination or revising the data model. Although Liu brought out the question of effectively expressing the conflicting evidences, there still exists the problem of effectively distinguishing the causes among conflicting evidences. We first put forward a new confliction-representation model; and then analyze and summarize the causes of conflicting evidences through numerical examples. These examples show the efficiency of the proposed confliction representation model. |
