Title: Congestion Management with an Aggregate Flow Model
Abstract: *Between January of 2003 and October of 2004 over, 215,000 hours of reportable delay are attributed to the FAA’s Traffic Management System. The cost of these delays to the nation’s airlines are on the order of $700 million. Although some of these delays may be unavoidable, the sheer complexity of the air traffic system coupled with the lack of adequate decision support capabilities often leads traffic flow specialists to adopt conservative and suboptimal policies for dealing with demand-capacity imbalances. In this study two linear programming models are presented that utilize an aggregate air traffic flow model for developing optimal policies for mitigating constraints and recovering a system previously impacted by a constraint. The utility of both of these models is illustrated for a three-region system that mimics air traffic flowing between inter-connected Centers in the National Airspace System. Results for this three-region system are generalized to provide guidelines for determining if solutions are feasible or infeasible for a given decision-making time horizon. It is envisioned that these new models could provide optimal control strategies to improve existing ground delay and ground stop programs. Specialists at the FAA’s Air Traffic Control System Command Center commonly use these two programs to resolve demand-capacity imbalances in the National Airspace System.
