Multi-sensor Information Fusion Weighted Average Algorithm Based on Decision-making Distance

This paper introduced some important concepts,such as the evidence-distance,the evidence support degree,the evidence credibility and the decision-making distance measurement.By given some rationalize processing to the trust function data of evidence,and achieved the result of the multi-sensor information fusion using the D-S evidence combination rules,then,this paper proposed a weighted average algorithm of multi-sensor information fusion based on decision-distance.Numerical example shows that the method can effectively solve the D-S conflict,and can ensure the accuracy of the information fusion.
