Abstract
A departure sequencing system models airport operations and provides suggested gate pushback times for aircraft. In various embodiments, a departure sequencing system includes an airport state analyzer, a taxi-out predictor, and a pushback optimizer. The departure sequencing system may utilize stochastic models, and resolve aircraft conflicts using a business rules engine. Via use of the departure sequencing system, taxi times may be reduced, taxi fuel burn may be reduced, and airport throughput may be increased.
Claims20
A method, comprising:
- modeling, by a processor for departure sequencing, aircraft ground traffic at an airport over a simulation time horizon, wherein the airport ground traffic comprises a plurality of aircraft scheduled for departure during the simulation time horizon;
- and
- determining, by the processor, a suggested gate pushback time for each of the plurality of aircraft.
A method for departure sequencing, comprising:
- creating a graph network representation of an airport;
- associating business rules to state transitions in the graph network;
- repeatedly executing, by a processor for departure sequencing, the graph network representation to obtain suggested gate pushback times for a plurality of flights;
- and
- calibrating, by the processor, a parameter of the graph network representation utilizing historical flight information for the airport.
A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, in response to execution by a processor for departure sequencing, causes the processor to perform operations comprising:
- modeling, by the processor, aircraft ground traffic at an airport over a simulation time horizon, wherein the airport ground traffic comprises a plurality of aircraft scheduled for departure during the simulation time horizon;
- and
- determining, by the processor, a suggested gate pushback time for each of the plurality of aircraft.
