| 摘要: |
| 为解决证据融合时证据间冲突衡量不准确问题，提出了一种新的证据冲突衡量方法。对当前冲突衡量方法国内外研究现状进行总结，结合典型算例分析，指出了当前方法存在的主要问题。基于前人研究成果，提出了一种改进冲突因子用于衡量证据间冲突，主要基于修正证据距离与合取冲突，对两者采用加性组合。通过一般类型算例与特殊类型算例对所提方法进行验证，结果表明改进的冲突衡量因子能够准确衡量证据间冲突，并具有普适性。 |

| Abstract: |
| The evidence conflict measure in Dempster-Shafer（D-S） evidence theory sometimes may be not accurate. In order to solve this problem,a new evidence conflict measure method is proposed. Research on evidence conflict measure methods at home and abroad is summarized and analyzed,and the problems of those methods are analyzed. Based on the foregoing research on evidence conflict measure,an improved conflict factor of evidence conflict is put forward,which is mainly built up by modified evidence distance and combination conflict factor. The improved conflict factor combines modified evidence distance and combination conflict factor based on the sum way. General types and special types of cases are used to verify the correctness of the proposed method,and the result shows that the improved conflict factor can measure the evidence conflict correctly and has universal applicability. |
