摘　　要：D-S证据理论是一种处理不确定性问题的有效方法,但是D-S证据理论组合规则的一些不足影响证据理论的应用。通过深入研究Dempster组合规则存在的问题,文章提出了一种新的基于Dempster组合规则的改进方法,理论分析和数值实验结果表明,改进后的方法弥补了Dempster组合规则不足,并能提高合成结果的可靠性。D-S evidence theory is a useful method to deal with uncertainty problems. But its application is limited by the shortcomings of the combination rules. Through in-depth researching into deficiencies in the Dempster combination rule, the new combination rule is proposed in this paper. Theoretical analysis and examples have been done to demonstrate that the new method is better than Dempster＇ s rule and can improve the reliability of the combination result.
