An Improved D-S Algorithm based on the Optimization Weight Distribution

In order to solve the invalidation problem of D-S evidence theory with high conflict evidences,on the basis of analyzing some typical improved methods,a new improved D-S algorithm based on optimization weight distribution is proposed.In the condition of ensuring the minimum of whole evidence conflict,sets up the distribution model of evidence optimization weights,then modifies original evidence model.Through analyzing the number examples,and comparing with other improved methods,the results show that the algorithm is more efficient to solve conflict evidences.
