| 摘 要： | 针对铁路客运站行车事故致因过程的动态性以及事故原因的模糊性,提出了一种Petri网图形建模同模糊控制理论相结合的分析方法.根据具体的事故产生式规则,建立了行车事故的模糊Petri网模型,进一步又将神经网络的BP算法引入到模型参数的学习中,通过给出的模糊推理算法,推理计算出事故的主要原因及可信度.最后将该方法应用到某客运站行车事故分析中,结果证明了其在事故分析中的准确性和可行性.

| Abstract: | Based on the dynamic development of train operation accidents of railway passenger sta-tion and the fuzziness of accident causes,a method combining Petri net and fuzzy control theory is proposed.The train operation accident model is built based on fuzzy Petri net according to acci-dent generated rules.BP algorithm of neural networks is introduced into the learning of model pa-rameters.Then the reasons and reliability function of accidents are reasoned by fuzzy reasoning al-gorithm.Finally,the proposed method is applied to the overrunning of signal accident analysis. The results show that the method is accurate and feasible in the accident analysis. |
