摘　　要：为了给乘客提供舒适的飞行体验,同时尽量减少乘客等待时间,提高机场安检效率。把机场中安检流程作为该文的研究对象,结合安检流程的特性,选择广义Petri网作为研究工具,以单通道的安检流程的简化情况建立数学模型并进行分析。在确认模型可靠的基础上,运用广义Petri网和马尔科夫链的理论得出评价安检系统性能的评价指标并进行相应的评价。最后以重庆江北机场中的安检流程作为实例,在没有限制资源的条件下,对重庆江北机场单通道安检流程进行分析,并引入到达率分析具有文化背景差异的乘客对安检流程的影响,最后提出相关的改善策略。In order to provide passengers with a comfortable flight experience,while minimizing passenger waiting time and improving the efficiency of airport security,this paper chooses the generalized Petri net as a research tool to establish a mathematical model and analyze it with the simplification of the single channel security process.This paper takes the security process in the airport as the research object and the characteristics of the security process.On the basis of confirming the model,the evaluation index of the performance of the security system is evaluated and evaluated by using the theory of generalized Petri net and Markov Chain.Finally,the process of security inspection in Chongqing Jiangbei Airport is taken as an example to analyze the single-channel security process of Chongqing Jiangbei Airport without restriction of resources,and the influence of passengers with different cultural backgrounds on the security process is introduced.Finally,Related improvement strategies will be proposed.
