A Simulation Analysis of Airport Security-Check Queues Based on Passengers’ Risk Classification

摘要: 本文研究基于旅客风险分类的机场安检排队线优化设计。我们开发了一个具有两种安检通道的安检排队系统仿真模型，在安检系统中风险门阀值被用来将到达旅客分为两种风险等级。此外，我们采用敏感性分析研究决策变量对所提出安检系统的平均等待时间和安全水平之影响。在本文中，感兴趣的决策变量包括用于指派旅客前往不同安检通道的风险门阀值和各安检通道的设备数量。本研究提出权衡通关效率和安全水平的优化策略。在数值实验中，我们对备选方案进行一系列的数据分析，揭示了安检排队系统的决策变量与整体性能之间的关系。最后，在敏感性分析的基础上，我们提出了优化安检排队线的运行机制，可为中国机场安检管理提供建议。

Abstract: This paper studies the optimization design of airport security-check queuing lines based on the passengers’ risk classification. We develop a simulation model of security-check queuing system with two types of inspection channels, where the risk threshold is used to differentiate the incoming passengers into two risk classes. In addition, we perform a sensitivity analysis to study the influence of the decision variables on the average waiting time and the safety level for the proposed security-check system. In this paper, the interested decision variables include the risk threshold used for assigning passengers to different inspection channels and the number of devices in each inspection channel. This study presents an optimization strategy for balancing the customs clearance efficiency and the safety level. In the numerical experiments, we conduct a series of data analysis on the alternatives, which reveal the relationship between the decision variables and the overall performance of the proposed security-check queuing system. Finally, based on the presented sensitivity analysis, we put forward an operating mechanism to optimize the proposed security-check queuing lines, which could provide useful suggestions for airport security management in China.
