| With the rapid development of the civil aviation industry,the capacity of flights is constantly increasing,which leads to aircraft delays in TMA.This not only increases the operation safety cost,but also increases the workload of air traffic controllers and crew members.Therefore,more advanced approach procedures are urgently needed.In order to overcome the difficulty above,this thesis designs corresponding point merge procedures for an airport in Shanghai,and study sequencing optimization of arrival aircrafts based on the Point Merge System(PMS).Besides,the configuration and operation characteristics of the point merge program are analyzed,and the system parameters are determined by combining the approach structure of the airport,the airport navigation positioning point,the minimum sector height and the design of system parameters of point merge procedures at home and abroad.On the basis of the point merge procedures of an airport in Shanghai,this thesis takes the aircraft approach route planning as the core,maintains the original airspace environment,and integrates flights.By evaluating the terminal area,aircraft types,obstacles and other aspects of the airport,the procedure design of multiple merge point is proposed,and the point merge procedures under high traffic load and low traffic load are demonstrated separately.On this basis,in order to improve the operation efficiency of approach flights of multi-runway airport based on point merge procedure,a multi-objective approach flight sequencing model is established with the total delay time,controller load and fuel consumption of the approach flights as the objective functions,and the minimum safety interval,sequencing arc capacity,maximum position exchange,flight time range of the approach flights and assignable approach procedures as the constraint conditions,and a hybrid algorithm with improved dynamic performance based on CPS and sliding time window method is introduced to solve the model.Compared with FCFS and traditional algorithm,this optimization algorithm reduces the total delay of aircraft by 19.1%,7.2%,694 s and 264 s respectively,and the fuel consumption by 978.09 kg and 471.18 kg respectively. |
