Optimally and equitably distributing delays with the aggregate flow model

Abstract: The aggregate flow model is used to determine how to distribute predeparture delays among air traffic control Centers and across time to optimally satisfy constraints on airspace capacity and departure rates. To do so, a quadratic cost on cumulative departure delays is introduced, resulting in an optimization problem that can be quickly solved using convex optimization tools. Simulations using the model demonstrate the behavior of the National Airspace System (NAS) when implementing optimal departure delays fo… Show more

“…The Disaggregated profile is the output from the disaggregation algorithm, which generates flightspecific action. Table 1 summarizes the costs defined by equation (16) for the real, simulated, optimized and disaggregated data. Clearly, the optimized solution has the minimal cost among the four, while the disaggregated profile obtained with flight-specific information has a larger cost.…”

“…Thus, in practice, it is difficult to make sound online air traffic control strategies based on the trajectory-based model due to the short forecast horizon and the expensive computational cost.Efficient ATFM requires reasonable prediction of the whole traffic flow situations in the specified airspace, rather than the temporal-spatial information of individual aircraft. Therefore, the aggregate air traffic flow models are introduced recently, which focus on the overall distribution of the air traffic flow in the airspace volumes of interest [5][6][7][8][9][10][11][12][13][18][19][20][21][22][23][24]. Because the aircrafts in the airspace volumes are spatially aggregated, the dimension of the aggregated model depends solely on the number of airspace volumes rather than the total number of aircrafts in the airspace, which will reduce the computational cost significantly.…”
