| 摘 要： | 证据合成方法将来自不同信息源的独立证据信息组合,产生更可靠的证据信息。但在证据完全冲突或冲突较大时,Dempster-Shafer证据合成公式失效。鉴于此,提出了一种新的证据合成方法,该方法充分考虑了证据在合成过程中的重要程度,通过引入权重系数和冲突概率的重新分配,新的合成方法提高了证据合成的可靠性和合理性,可得到更为理想的合成结果。

| Abstract: | The evidence combination method is the key part of the evidence theory.It can combine the independent evidences from different information sources to acquire more reliable information.However,its application is limited by the shortcomings of Dempster-Shafer evidence combination method.This method may be useless when the conflict among evidences is rather great or even complete.A new evidence combination method is presented.In this improved method,the importance of the evidences is calculated.It enhances the rationality and reliability of the evidence combination through introducing weight coefficients and allotting the conflicted probability again and better results can be acquired. |
