针对经典D-S证据理论(Dempster-Shafer Theory)在合成高度冲突证据时得到与直观结果相悖的问题,提出一种新的冲突证据融合方法。该方法综合了修改原始证据源和改进Dempster合成规则两类方法的优点,通过引入冲突因子和证据间一致性系数等概念定义两证据间的相关度。实验结果表明,该方法与其他方法相比能客观反映证据的可信度,融合结果也更符合实际情形。
針對經典D-S證據理論(Dempster-Shafer Theory)在閤成高度遲突證據時得到與直觀結果相悖的問題,提齣一種新的遲突證據融閤方法。該方法綜閤瞭脩改原始證據源和改進Dempster閤成規則兩類方法的優點,通過引入遲突因子和證據間一緻性繫數等概唸定義兩證據間的相關度。實驗結果錶明,該方法與其他方法相比能客觀反映證據的可信度,融閤結果也更符閤實際情形。

To overcome the problem that traditional D-S evidence theory in combining height conflict evidence disobeys straightforward re-sults,the paper proposes a new conflict evidence fusion method.The method combines the advantages of both modifying original evidence source and improving Dempster combination rules and by introducing such concepts as conflict factors,coherence coefficients among evidences and so on,defines the correlation degree between two evidences.Experiment results illustrate that,compared to other methods,the proposed method can reflect evidence reliability more objectively while the fusion results better fit actual situations too.
