Abstract: To alleviate the problem of unreasonable flight delays, coordinated optimization of airport slot based on air-ground integration is proposed. This thesis takes the system which consists of parking stands, runways and waypoints as the research object, in perspective of the collaborative decision -making of air traffic control, airports and airlines, and establishes an optimization mathematical model of the maximum normal rate of airport release based on the actual operation of the flights. The strategic optimization results are studied with the aid of CPLEX solver. In addition to the basic operational restrictions of the airports, the model also introduces the waypoints capacity as innovation. The actual operation data of Nanjing Lukou Airport are used to verify the assumption. The optimization results show that flight number for optimization decreases as flow control increases, the total departure delay decreases by 486 min, while the normal release rate increases by 14.8%.

Key words: optimization of airport slot, air traffic management, waypoints, collaborative decision making
