Study On Capacity Optimization Of Terminal 3 Of Beijing Capital International Airport

The rapid development of air transport has promoted the rapid increase of air traffic flow,resulting in the increasingly serious contradiction between the growth of traffic flo w and the constant airport capacity.Terminal capacity is an extremely important part of ai rport capacity,and the rapid development of air transport will lead to congestion in the t erminal.It greatly affects passengers' flight experience and even leads to an increase in a irport flight delay rate.Therefore,the optimization of terminal capacity,the improvement of terminal service quality and the reduction of flight delay rate have become the urgent problems to be solved in airport capacity research.In order to solve the problem of insufficient terminal capacity,there are two mainstr eam research technologies.Firstly,mathematical models,equation of states and algebraic equations are established through Petri nets to analyze and verify the behavior of passen gers in the terminal,and find out the minimum capacity required by the terminal and re alize airport capacity optimization.Secondly,considering the complexity of passenger beh avior in the terminal,the queuing theory models are established to realize the scheduling optimization of various processes in the terminal,and the capacity optimization of the te rminal.For the T3-D and T3-C terminals of Beijing Capital International Airport,Petri net t echnology and queuing theory model are respectively used for the research.The followin g work is completed in this paper.(1)A scheme for calculating the minimum capacity of terminal T3-D based on Petri net technology was proposed.According to the behavior flow of passengers in terminal T3-D,a flight guidance system is established with a Petri net model.Under this model,a ccording to the input and output of passenger flows in terminal T3-D,the minimum capa city of terminal T3-D is calculated by using the correlation matrix analysis and identifica tion deduction method in Petri net.This scheme can not only avoid passenger congestion and flight delays in the terminal,but also save the construction cost of the terminal and avoid the waste of ferries.Finally,the correctness of the scheme is verified by the real d ata of T3-D terminal.(2)This paper proposes a capacity optimization scheme for terminal T3-C based on queuing theory models,which analyzes the structure composition of terminal T3-C and divides terminal T3-C into several functional units.The queuing theory model of each functional unit is established and the corresponding mathematical model is given.Under this model,the capacity of each functional unit is calculated and fully utilized to improve the terminal capacity.Finally,the correctness of the scheme is verified by the real data of T3-C terminal.In summary,this paper uses Petri net technology and queuing theory model to an alyze the capacity of the terminal building of Beijing Capital International Airport,so as to achieve the goal of optimal utilization of terminal capacity,avoid passenger con gestion and flight delay,and improve the service quality of passengers in the terminal.
