Optimization Model of Airport Security Screening

Airport security is a necessary link for passengers to enter the airport. In this paper, we established a multi-server queuing model to optimize the airport security screening. Concretely, the whole queue process of security screening is decomposed into some parts. For each part, we established a multi-server queuing model, and used the number of passengers in the queuing system and the service intensity to evaluate the model. By utilizing the collected data, we identify the bottlenecks that are mainly caused by the number of open lanes and the service rate of a staffing.
