An Efficient Approach for Conflict Evidence Combination
Xiaoguang Yuan · Electronics Optics & Control · 2010
Considering the combination of conflict evidences and the difficulty in determining the Basic Probability Assignment Function(BPAF) in the application of evidence theory,a new method for conflict evidence combination is put forward.The method is based on a modified evidence model and the structure of Dempster's combination rule is not modified.First,considering the correlations between focal attributes and between evidence,a distance function between the bodies of evidence is introduced.Then,the support degree and the credibility of each evidence are obtained.The conflict evidence is superseded by average evidence.Finally,the Dempster's combination rule is used to realize information fusion.In simulations,the proposed method is compared with the existing combination methods,and the result shows that the method is an effective and feasible method for conflict evidence combination.
