Processing Methods on Conflict Problems of Multi-source Information Fusion Based on D-S Theory
Zhihong Feng · Computer Engineering and Applications Journal · 2006
D-S theory has evidently predominance in presentation,measurement and combination of uncertainty information,which make it extensively applied to multi-source information fusion.However,to priority,reliability and importance of evidence,Dempster combination rules do not take account of them,which brings invert-intuitionistic results during evidence reasoning,that is to say,conflict problems.Including general conflict problem,a vote down problem and robustness problem,the conflict problems of multi-source information processing based on D-S theory are analyzed in the paper.We indicate the advantages and disadvantages of methods solving the problems.Finally,problems of the methods and direction of further development are proposed.
