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. |

1. A method for departure sequencing of a plurality of aircraft at an airport, the method comprising:
scheduling, by a computer, a departure time for a first aircraft of the plurality of aircraft that is modeled on gate node business rules; initializing, by the computer, the status of the first aircraft flight that is modeled on gate node business rules; allowing, by the computer, the first aircraft to occupy a node, in response to the first aircraft approaching the node, a next ground link having available capacity and the node not being occupied by a second aircraft, checking, by the computer, potential future directional head-to-head aircraft conflicts with the second aircraft to avoid gridlock; triggering, by the computer and in response to the second aircraft waiting on the last ground link, movement of the second aircraft forward as more space is made available on the next ground link; releasing, by the computer, the node of the currently occupying aircraft; creating, by the computer and in response to the second aircraft waiting for the node, a trigger to enter the node for the second aircraft; implementing, by the computer, business rules for checking runway blockage by arrivals or crossings; triggering, by the computer and after a take-off, another take off event in response to the first aircraft waiting on the runway entrance node and no blockage is applied; and obtaining, by the computer, suggested gate pushback times for the first aircraft at the airport. |
