Research On Airspace Dynamic Programming And Dynamic Allocation Of Flow Technique In The Flexible Use Of Airspace

Flexible use of airspace can improve the utilization of airspace and facilitate the development of the air transport industry. Currently, the use of airspace lacks of flexibility in our country resulting in a waste of airspace resources. Airspace dynamic programming and air traffic flow dynamic allocation technology are the keys to achieve flexible use of airspace. The area controlled airspace dynamic programming, dynamic sector division of the terminal area and a traffic flow dynamic allocation techniques of the terminal area have been done in this paper.Firstly, Voronoi diagram is established according to natural distribution of the waypoint and main navigation facilities during peak periods, a static sector division is achieved based on existing numbers of sector and balancing the air traffic controller's workload between the various sectors. Then sector adjustment has been done by a proposed combination algorithms during non-peak periods so that the area controlled airspace dynamic programming is achieved. Finally, an area controlled airspace is used as an example to verify the feasibility and rationality of the area controlled airspace dynamic programming.Secondly, integer programming is applied to the terminal area sector dynamic partitioning based on the actual traffic flow. Regular of intervals, geometric demands of the flight path and constraints of the runway construction have been considered as constraints. Then the terminal area is divided based on the optimal solution. Finally, a terminal area is used as an example to verify the feasibility of the integer programming model.Thirdly, a traffic flow dynamic allocation techniques of the terminal area is proposed based on the shared fixed-point of the approach and departure. Firstly, traffic flow integrated of the approach and departure model is proposed. Then a non-sorting genetic algorithm is used to solve the model. Finally, a terminal area is used as an example to verify the traffic flow integration of approach and departure can enable terminal area dynamic allocation.
