Our approach Wisely postpone artificially departures to maintain bank integrity and prevent passengers from missing connections Wisely canceled flights if necessary to prevent delays to propagate and the negative effects on passengers We want our solutions to be feasible for aircraft (maintenance)and crews(schedule) Guarantee solution feasibility: Artificially postponing flight departures does not disrupt more crews Maintain flight sequence feasibility (duty) Does not include flight copies that violate crew regulation Maximum Duty Elapsed time Do we guarantee maintenance routing feasibilityOur approach • Wisely postpone artificially departures to maintain bank integrity and prevent passengers from missing connections • Wisely canceled flights if necessary to prevent delays to propagate and the negative effects on passengers • We want our solutions to be feasible for aircraft (maintenance) and crews (schedule) • Guarantee solution feasibility: ¾ Artificially postponing flight departures does not disrupt more crews: • Maintain flight sequence feasibility (duty) • Does not include flight copies that violate crew regulation (Maximum Duty Elapsed Time) • Do we guarantee maintenance routing feasibility?
