Abstract

The invention belongs to the field of air traffic management and provides a space domain sector partitioning method based on a weighted graph model. After an undirected graph model capable of accurately showing airway and air traffic volume is established, a space domain is discretized by taking a graph vertex as a Voronoi graph base point, and then the weighted graph model is established according to the work load of each Voronoi graph unit and the traffic volume of the airway. The weighted graph model is partitioned into a plurality of subgraphs by utilizing a graph partitioning method which merges a common weighed graph algorithm, a load balance algorithm and a heuristic algorithm, and a vertex contained in each subgraph is mapped to a corresponding Voronoi graph unit to form a sector. The sector designed by the method not only can meet minimizing constraint of load balance and cooperative load, but also can meet minimal distance constraint, convexity constraint and connectivity constraint of the sector.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, and relates to an airspace sector design scheme in air traffic management, in particular to a scheme capable of satisfying sector load balancing and handover load minimization and ensuring sector convexity, minimum distance and connectivity. A sector division method with geometric constraints such as sex. Background technique [0002] At present, the airspace organization forms of most countries in the world are fixed routes and fixed sectors, that is, aircrafts fly along fixed routes, and the sector boundaries and the number of sectors are fixed. This is a structured static airspace. This static airspace is prone to flight delays during bad weather and heavy air traffic. In order to solve the above traffic problems, the researchers proposed the concept of dynamic airspace configuration to meet the needs of airspace users. Under the dynamic configuration, the aircraft can fly fr...
