Optimization Design And Feasibility Analysis Of Airport Security Check Mode

At present,the civil aviation has become the important way of people's travel and express delivery.Airport security is not only facing the severe international terrorism in the situation,but also will be tested the huge passenger flow and limited security resources.As the premise to ensure safety,for practical and effective improving the efficiency of airport security,this paper conducts on-site investigation and research of the airport security inspection environment,data collection,testing,and analysis.It identifies targeted bottlenecks and optimizes the design.On this basis,this paper introduced the idea of classified security,classified the passenger risk level,designed the security channels matching different security risks and the classified security scheme suitable for domestic airports.Through the cost estimation,questionnaire survey and optimization results,the feasibility analysis of the optimized plan was carried out,and the plan was evaluated and improved in order to provide a useful discussion on the construction of the security inspection of large-scale hub airports.This article selects a large hub airport as the research object,through on-site interviews,according to the security inspection process and the security regulations collected on-site testing of the security inspection of the links of the time,to identify the bottleneck of security inspection efficiency.Using problem tree analysis and queuing theory,under the premise of not changing the intensity of existing security inspections,an X-ray machine with additional auxiliary maps,a modest increase of baggage buffer zone and baggage reorganization zone,an increase of manual inspection posts and an increase of security inspections were proposed.Remind SMS and other measures to optimize the program.A rapid security screening channel and a 100% opening rate for security inspections are proposed so that security screening resources can be concentrated on passengers with high security risks and low-risk passengers can quickly pass through security inspections.In order to further improve the efficiency of security screening,a classification security plan suitable for China's situation was designed,and a networklevel analysis method was used to classify passenger security risk levels.Using the Anylogic pedestrian library simulation software based on social force model and queuing theory,the proposed security optimization program was simulated and analyzed.Through simulation and analysis,it is found that the optimization configuration of the 5m front buffer zone,3m baggage handling zone and 3 hand inspection posts is the best.The simulation results show that the pass rate per pass of 82 persons per channel is 23.17% higher than that of the existing airport security model,and the average time taken by passengers is 10.288 minutes,which is 28.26% lower than the existing security model.The classification security optimization program simulation results show that when the sampling rate of rapid security screening channel is 40%,the overall passing rate is 44.51% higher than the existing security model,the time for low-risk passengers is reduced by 47.84%,and the time for high-risk passengers to pass inspection Increased by 33.45%.Using the questionnaire survey and cost estimation method to analyze the feasibility of the optimization program,the results of the questionnaire survey showed that 84.4% of the respondents agreed with the optimization method of the security inspection reminding message,and the simulation and verification results of the optimized program can also reach their psychological expectations.In terms of cost estimation,the cost of the security optimization plan is 7.92% lower than that of the existing security inspection model,and the theoretical cost saving rate of the classified security optimization plan is 21.05%.
