随着交通流量的不断增大,安检流程的标准化变得越加重要。为了保障旅客出行顺利提高安检效率,本文通过采用佩特里网和马尔可夫链相结合的方法,针对非标准化一般安检流程进行瓶颈判断及仿真优化分析研究。 As traffic volumes continue to increase, the standardization of security processes becomes more and more important. In order to ensure the safety of passenger trips and improve security efficiency, this paper uses the method of combining Petri net and Markov chain to judge and optimize the bottleneck of non-standardized general security inspection process.
