Abstract:

In view of the weaknesses of current short-term area traffic flow management models in constraint conditions and control methods, a new concept and its corresponding constraint conditions of flow control events are established. In addition, based on dynamic network flow theory, a time route assignment model with flight level decision parameters for short-term area traffic flow management is proposed to meet the need of Chinese air traffic flow management (ATFM) work. Simulated annealing genetic algorithm is applied to seek the solution of the model, which is intuitionistic and explicit for the air traffic controllers. The model is then verified by real operational data from a flow control event that occurred in the East China air traffic control (ATC) center. The computational results indicate that the model and solving method are feasible and effective.
