Research On The Validation And Optimization Of The New Security Check Mode Of Large Aeronautic Hub

At present,civil aviation has become one of the main ways for people to travel.But with the boom in the number of passengers,the civil aviation safety faces the test of limited security resources and tremendous security pressure.In order to ensure the safety of civil aviation transportation and improve the level of security check,this dissertation discusses the new security check mode.The main objective of this dissertation is to test the thoroughness and checking time of new security check mode,analyze satisfaction of the passengers and working experience of security officers,then put forward optimization program to improve the efficiency of security check.A new security check mode was chosen as the research object.We compared the checking thoroughness of security equipment of new mode by using the methods of luggage regional division and human body area label.The results indicate that,compared with the X-ray machine and metal security door,CT security equipment and millimeter-wave device have better performance in detecting contraband.The whole and period time of security check of new mode was tested by drawing security check line and designing time record card.The results demonstrate that the checking time of the combined mode is the shortest,the average time spent in the security channel is 109.7 seconds.This dissertation contrasted the satisfaction of passengers and working experience of security officers of different groups by means of questionnaire survey.The results indicate that age,education,occupation are key factors,overall the satisfaction of passengers of different groups has no significant difference;the conveniency of security equipment is a key factor to the working experience,and security officers working in new mode have higher evaluation.The maximum number of passengers going through within an hour was tested by using Anylogic to simulate the process of security check,and the crowd gathering area of the channel was found out.The simulation results indicate that the combined mode had seized the highest number of passengers,at about 185 people;the main crowd gathering areas are located in X-ray machine's front sliding table and passport control area.By adjusting the parameters of key factors,this dissertation got The results indicating that in order to maximize the number of passengers going through within an hour,in the conventional mode and combined mode,we should assign 2 hand inspectors and design 5 meters long front sliding table;in the CT security check mode,we should assign 2 hand inspectors and design 3 packing areas.
