In this paper, an improved evidence combination method is proposed to address the paradox problem of Dempster-Shafer theory when dealing with highly conflict evidences. Considering that the counter-intuitive combination result of Dempster's theory is related to both the unreliable evidence and the unreasonable distribution of the conflict evidences, the method combines the evidence preprocessing and...
This paper proposes a selectivity criterion to choose appropriate information fusion method for the fusion of multiarguments to acquire logical consensus output. The research theory can improve the cognitive veracity of the object based on the redundancy of information, and can resolve the problem of incompletion about detected data. Firstly, the characteristic of D-S evidence theory is analyzed....
Dissolved Gas Analysis (DGA) is usually performed for power transformer condition based maintenance (CBM) activities. In reality, the interpretation of DGA data is complex and done through several knowledge sources. Lack of information within these knowledge sources necessitates an information fusion methodology. Constructed upon Dempster-Shafer (DS) theoretic approach, this paper proposes a novel...
