Abstract

To avoid the airport congestion and reduce flight delays, the paper studied the airport traffic balance from a system perspective at the strategic level. By considering the single-airport approach and departure as well as the correlation between the multi-airport connecting flights, the paper proposed network system on traffic flow which is open and has a direction in multi-airport; the paper set up multi-airport open network assignment model which was based on constraint capacity and multiple connecting flights and which minimized the total delay of all flights in the network within the target. The model was simulated which combined on the three major airports’ actual flight data in domestic. Simulation results show that: the proposed model can coordinate and optimize the matching of multi-airport network traffic and capacity. It also can minimize the system’s delayed flights based on using of system capacity; the paper can deploy optimization strategy in traffic flow for air traffic control sector and provide supporting decision-making basis for the civil aviation department of the flight plan.

Key words: Air traffic flow management, multi-airport, assignment, optimization.
