Research On Multi-airport Capacity Co-optimization In Yangtze River Delta Region

With the rapid development of the economy in the Yangtze River Delta region,the flight traffic in the region has grown rapidly,which has made the inter-constraints between different airports increasingly serious,and the normality of flights and passenger experience have declined.Therefore,the correlation between the operation of each airport in the regional multi-airport system is studied,the coupling relationship is quantified,the rationality of airport capacity utilization and flight flow allocation in the system is improved,and a relatively complete flow-to-pool collaborative management mechanism is formed.The key to the efficient operation of regional multi-airport systems.This paper mainly studies and verifies the multi-airway flow characteristics and collaborative optimization methods in the Yangtze River Delta.Firstly,the static structure characteristics and dynamic operation characteristics of the multi-airport system in the Yangtze River Delta are described.The quantitative anal ysis shows that the multi-airports in the Yangtze River Delta have higher mutual restraint and greater mutual influence.Based on this,the data mining method is used to study the fluid-flow coupling characteristics in the multi-aircraft system of the Yangtze River Delta.It shows that the multi-airports in the Yangtze River Delta are highly correlated with the operational capacity and flight flow allocation,resulting in the operation of the airports in the Yangtze River Delta.Mismatch problems occur frequently.Aiming at this problem of capacity flow mismatch,this paper proposes a flight capacity optimization method based on fixed capacity,a flight flow optimization method based on coupling capacity and a flight capacity allocation method based on dynamic capacity,and combines the optimal control theory to initially construct an airport operation index.Evaluation System.Finally,the AirTOp software is used to construct the multi-airport full airspace simulation model of the Yangtze River Delta,and th e flight flow is redistributed according to different capacity adjustment ranges.The simulation model is used to evaluate various schemes from the aspects of flight flow situation,operational efficiency,safety and controller load.Advantages and disadva ntages,the optimal control interval of each airport capacity is analyzed,and the optimal distribution of flight flow and coordinated optimization of overall regional flow capacity are realized.
