Study On Taxiing System Optimization Of Multi-Runway Airport

With the continuous development of civil aviation transportation,due to the limited scene resources,many airports cannot meet the increasing traffic demand.Therefore,many domestic airports have chosen to build multiple runways to increase their capacity.The airport taxi system,as a key part connecting the airport runway with the gate,improves the operational efficiency,which can also determine the upper limit of the airport capacity to a certain extent.Therefore,how to optimize the aircraft's taxiing path,improve the aircraft's ground operation efficiency,reduce ground-to-ground conflict,and increase operating capacity have become hot topics.Based on this,the following research work has been carried out:First,the multi-runway airport with an end-around taxiway is researched to clarify the concepts of the end-around taxiway and the strategy for the aircraft to use the end-around taxiway.Analyze the fuel consumption of the aircraft in different states during taxiing to obtain a plan for the aircraft to use the bypass taxiway;then,optimize the minimum fuel consumption during taxiing of the aircraft as the optimization goal,and combine the aircraft's ground taxi rules,conflict avoidance and runway Crossing is used as a constraint to establish an aircraft taxi path optimization model,and an improved ant colony algorithm is used to solve,analyze and verify the model.Secondly,considering that the taxiing path of the aircraft on the airport ground has attracted the attention of airlines and airports,a multi-objective optimization 0-1 integer planning model of the aircraft's ground taxiing path was established to minimize the total time of the aircraft's ground taxiing and the aircraft's taxiing fuel consumption.Optimize the target and use the improved ant colony algorithm to solve the model.Finally,the first two chapters focus on the optimization of the single resource system of the airport taxi system,and consider the interaction between the various systems of the airport during the peak hours of the close parallel runway airport.Introduce a two-level planning model to model the taxiway and runway joint scheduling;the upper model is the aircraft for runway scheduling,that is,time assignment for departure and departure flights,and the lower model is for aircraft taxi path allocation.A heuristic algorithm is designed to solve the model using a loop-nested iterative method.
