Research On Aircraft Ground Operation And Jointed Scheduling At Large-sized Airport

With increasingly development of air transport industry,it’s bound to cause rapid growth of air traffic flow for airport terminal,especially large-sized airport,it will highlight the contradiction between the sharp increase of demand and the limited capacity.So research on the operational characteristics of large-sized airport surface is a necessity for easing aircraft operation congestion and making full use of slots is an effective way to improve the efficiency of aircraft operation at airport surface.Since airport terminal area is the bottleneck of air traffic management in China,the importance to research aircraft operating characteristics and make full use of slots is self-evident.In this dissertation,the cell transmission network model of airport ground is built first.Secondly,study the influence of traffic flow among runway,taxiway and apron.Finally,provide two pespectives from planning and dynamic scheduling to get rid of ground congestion:In this dissertation,the status quo,the latest research results and problems of aircraft scheduling in China and abroad are summarized comprehensively;the relevant theoretical foundation and main research results of traffic flow at airport surface are analyzed deeply;aircraft operating characteristics,the formation mechanism of congestion and its shake-off strategy are dissertated systematically.According to the particularity of aircraft operation on a runway,taxiway and apron,from the cellular perspective,the three kinds of cellular flow,velocity and density are defined.Based on the particularity of runway,taxiways at the end of the runway are incorporated into the runway system to construct the runway system cell.Based on the definition of traffic flow,build the cell transmission network model for runway,taxiway,apron and the whole airport surface.Since the limited runway capacity,dynamically allocate the approach runway capacity and departure runway capacity.Simulating the aircraft operation of runway,taxiway and apron,with the fixed approaching rate of aircraft,is on the platform of NETLOGO,and divides the traffic flow phase for each module according to the characteristics of aircraft operation.The simulation results show that if the runway capacity is allocated dynamically,the traffic flow will be form circulation and the radius will decrease gradually.The characteristics of traffic congestion at large-sized airport surface are studied.Firstly,define the measures of traffic congestion;then study the effects of the parameters’ value of three kinds cellular on the measures;finally,analyze the influences between traffic parameters belonging to three kinds cellular.When traffic flow effects between three kinds cellular are known,take their length or capacity as the variables and take one or more maximum value of three kinds cellular flows as the objective function to build optimal resource allocation model and variant genetic and simulated annealing algorithm is used to solve the model with MATLAB.Pareto dominance is used to deal with multi-objective functions and pick out the optimal solution for obtaining the optimal resource capacity allocation.Take aircraft operation velocity as variables and the maximum cellular’ flow as objective function to build the model under the premise of the optimal resource capacity allocation to get approximate optimal value of velocity.According to the situation of airport surface aircraft operation,firstly respectively define slot loss of runway,taxiway and apron,then take the minimum slot loss as objective function to build airport surface joint scheduling model for obtaining the best launching time belong to the aircraft at the stand.Finally,the dissertation summarizes the main research results and problems.In a word,the dissertation’s researches not only consummate aircraft scheduling theory and methods at large-sized airport surface,but also have some guiding significance to planners and dispatchers in practical application.
