Research On Airline Coordination Optimization Method Of Multi-airport System

The coordinated development of Multi-airport system is the trend of future.However,the division of labor within multi-airport system is not clear.The advantages of location between multi-airport system and multi-airport system are not fully utilized,and the convenience of transportation within multi-airport system is not brought into play.With the increase of flight time,the flight volume of hub airports has reached saturation,even some airports have been overloaded.However,the development of non-hub airports within airport clusters is slow,the number of flights is low,the internal development of airport clusters is unbalanced,and the location is not clear.How to coordinate the routes between airport clusters and rationally allocate flight time resources is the key to achieve the coordinated development of airport clusters.Taking Multi-airport system of Yangtze River Delta and Pearl River Delta as examples,this paper studies the airline coordination between multi-airport system.On the basis of understanding the current research situation,this paper elaborates the overview of multi-airport system,the definition of multi-airport system,the analysis of typical multi-airport system abroad,the experience of multi-airport system development,the analysis of multi-airport system development in the Yangtze River Delta and the Pearl River Delta,the discussion of the development of multi-airport system,the study of coordinated development of multi-airport system,and the necessity of multi-airport system route coordination.The current situation and problems of multi-airport system classification are discussed.Based on the time distance,the boundaries of multi-airport system are divided,the airport is clustered,and the principal component analysis is used to analyze the routes to determine the optimal range of routes.Logit model is used to forecast the passenger flow in the Yangtze River Delta and Pearl River Delta,and an multi-airport system flight coordination optimization model considering intermodal transport is established.The results are solved by dividing and conquering algorithm.The simulation results are verified by TAAM software.The simulation results show that the multi-airport system route optimization will reduce the sector load and route delay.Flight schedules have been applied more optimally.
