Abstract:

In order to effectively adapt to traffic demand changes in time and space,based on quantization of the aircraft number in the function block and multi-ATC team,an adaptive sector reconfiguration assignment model and an algorithm are proposed. When the target airspace has been processed as grid,statistics of the evenly distributed aircraft number are obtained in each grid. Aircraft distribution coefficients are used to correct the extra workload while air traffic controllers conduct coordination,transferring and resolving conflicts. Then the amended aircraft distribution numbers are alluded to each grid. A backpack assignment model and calculation method is designed for grid grouping on condition of multi-period,variable job number and variable capacity. Numerical examples show that the model is feasible as while as algorithm is effective. On high demand day,assignment algorithm results reduce about 15% of human resource needs than current needs under three crew shifts. On low traffic demand day,the assignment algorithm results still can reduce about 8%of human resources needs.
