Abstract:As an important part of flight departure, airport security check is very necessary to reduce the operating cost of the security check area and reduce the waiting time of passengers. In view of the bottleneck problem in the security queuing system, the idea of optimizing the layout was proposed, and the existing resources in the security queuing system were used to establish a dual-objective optimization model of the security queuing system based on the idea of resource optimization, taking Shenzhen Bao'an International Airport as an example. Through the NSGA-II algorithm, the Pareto optimal solution set of the resource allocation scheme was obtained, and then the Pareto optimal solution set was sorted by using the TOPSIS method, and the optimal configuration scheme with comprehensive benefits was obtained. The number of open channels in the level I system is 17, and the number of open channels in the level II system is 35. The results show that the proposed method eliminates the difference between the dimensions of operating cost and waiting time, and provides a solution for the optimization goal of the existing game.
