Fast combination method of conflict evidences in multi-source uncertain information fusion
Dongying Bai · Systems engineering and electronics · 2012
The combination rule of conflict evidences and the required heavy computational load have been the important issues in Dempster-Shafer(D-S) theory.Many improved methods have been proposed,but each of them has their limitations.For example,the Murphy method,though efficient for solving the conflict evidence to a great extent,still leaves the heavy computational load open.On the basis of the research to the Murphy method,the combination law of identical evidences is discovered,and then a fast Murphy combination rule(FMCR) and the related expression are proposed.Experiments show that the new rule can effectively deal with high conflicting evidence and multi-source uncertain information fusion problems with an improvement in speed and accuracy.
