一种加权改进的D-S证据推理算法

AN ALGORITHM OF D-S EVIDENTIAL REASONING BASED ON WEIGHTED IMPROVEMENT

利用证据推理方法处理不确定问题具有强大的优势,但由于它不能处理矛盾证据,这在很大程度上限制了它在实际中的应用。对D-S证据推理的算法进行了改进。改进后的D-S证据推理算法可以有效地处理矛盾证据,取得比较理想、比较合理的融合结果。最后,通过仿真试验对该方法进行了验证。

Evidential reasoning has dominant advantage when it is used to tackle contradictions greatly.In this paper,the authors have improved the algorithm of D-S evidential reasoning.The improved algorithm can effectually manage the contradictory evidences and achieve a fuse result that is more perfect and reasonable.At last,the algorithm proposed in the paper is attested through some simulative experiments.
