The evidence combination problem in Dempster- Shafer's theory is studied in the paper. The including degree for the focal element of fuzzy evidence is defined. As an extension of Dempster's rule of combination, a new combination method for fuzzy evidence is put forward, thus the application fields of evidence theory are widened.

本文研究Dempster-Shafer理论中的证据合成问题。文中定义了模糊证据焦元的包含度,提出了一种模糊证据合成方法作为对Dempster合成规则的一个推广,从而拓宽了证据理论的应用范围。

A new information fusion approach based on extended Dempster-Shafer theory is proposed to diagnose simultaneous faults. Simultaneous faults are introduced in the frame of discernment and two different combination rules are established. The first combination rule fuses these bodies of evidence with same focal elements, the second combination rule fuses these bodies of evidence with different focal elements. Finally, a case study pertaining to the fault diagnosis for rotor-bearing systems is given,...

A new information fusion approach based on extended Dempster-Shafer theory is proposed to diagnose simultaneous faults. Simultaneous faults are introduced in the frame of discernment and two different combination rules are established. The first combination rule fuses these bodies of evidence with same focal elements, the second combination rule fuses these bodies of evidence with different focal elements. Finally, a case study pertaining to the fault diagnosis for rotor-bearing systems is given, and by comparing and analyzing the diagnosis results based on the first combination rule and the second combination rule respectively, it is shown that the presented diagnosis approach is feasible and efficient.

为了诊断并发故障,文中扩展了证据理论:将并发故障状态作为设备的运行状态引入分辨框Q中,视其为独立的运行状态,并根据不同证据体的差异程度,提出了两种不同的证据组合算法。然后,应用此两种不同的证据组合算法于并发故障诊断:第一种融合算法用来处理有相同焦点元素的证据体;第二种融合算法用来处理有不同焦点元素的证据体。该算法有利于充分利用各种证据体的有用信息,具有较强处理不确定性、不一致性证据体的能力。通过实验台转子轴承系统并发故障的诊断事例,证实了该算法的有效性。

This paper summarized theories and methods for the combination of interrelated evidences, discussed the scourge of current combination methods, and presented a new combination method for interrelated evidences through analysis of focal element of interrelated evidences. The method focuses on the adjustment of basic probability numbers of interrelated focal element. It improves current adjustment methods that adjust all focal elements, makes the adjustment object more reasonable. The adjustment coefficient can be obtained through learning based optimal methods. This method can be used to combine interrelated evidences while the basic probability numbers of interrelated evidences are unavailable. An experimental computing shows the results is satisfactory.

总结了相关证据合成的理论方法,分析了已有合成方法的不足,对相关证据的相关焦元的分布情况进行了分析,提出一种面向问题的基于可变参数的相关证据的合成方法.方法只对相关焦元的基本可信数进行修正,克服了对相关证据所有焦元进行修正的弱点,使修正的对象更加合理,修正系数可用基于学习的寻优方法得到.在相关证据的相关焦元的基本可信数未知的情况下也可进行相关证据的合成.计算结果表明该方法对合成的结果有明显的改进.
