Modeling and Analyzing Train Running Delays Causation Based on an Extended Fuzzy Petri Net
摘要
Abstract
In view of the serious situation of train running delays,an extended fuzzy Petri net was proposed(extended fuuzy Petri net,EFPN),and on the basis of some critical factors easily causing delays,a train delay causal analysis model based on EFPN was constructed after simulating and analyzing the causality of the given factors. EFPN reasoning algorithm was used to analyse and calculate the validity of the factors which lead to train delays,and the highest validity of the cause is the most key factor of train delays. Case analysis indicates that EFPN model can reflect the logical relationship among various factors,and it can get the main causes of train running delays through quantitative analysis.关键词
