Research conflict problems of D-S evidence and its application in multi-sensor information fusion technology

The D-S reasoning has evidently predominance in presentation, resolution and combination for uncertainty information problems, which makes it can be effectively applied in multi-sensor data fusion. However, the Dempster combination rule doesn´t take proper measures to address the reliability, conflict and importance aspects of measuring the source-evidence itself, this weakness may result in the existence contrary to intuition in reasoning process. A synthesis rule, especially the conflict problems produced by the data fusion involved in the D-S reasoning synthesis rule based on the basic ones has been analyzed in this paper. Also, a improved synthesis formula of D-S has been put forward according to the conception of evidence information and the focal element generated by itself, and it is applied in the multi-sensor information fusion technology, As indicated by the simulation results that the method proposed is a feasible, effective solution.
