Improved system, device and method for sequencing modes of transportation or items and the like

A system for optimizing a sequence of aircraft at an airport receives flight plan data (comprising flight schedule data) for multiple journeys of respective aircraft. Aircraft taxi time (EXOT) is determined from the flight plan data and, for each journey, a target take-off time (TTOT) is determined from the EXOT and flight plan data. A target start-up time (TSAT) may be determined from the TTOT. Multiple different TTOT and TSAT for each journey may be associated with the flight plans. The flight plan data may define a target off-block time, runway, call sign, time stamps or aircraft type, registration or origin and destination. Optimizing the sequence may comprise minimizing temporal aircraft separation according to aircraft size, speed class or departure route. The system may monitor aircraft turnaround events (e.g. actual landing, in-block or fueling start or end times) and trigger event updates based on deviation of a different event from target times. It may optimize de-icing according to aircraft type or de-icing location or determine actual arrival and departure capacity of the airport from weather or traffic demand data.
