Airline Recovery Model, the Model Suite for the Real-Time Management of the Operational Irregularities
Planning model of fueling and crew schedule is a terrible headache of the airlines companies that engage their resources to maintain and recover the planned operations. The growing competition reduces the tolerance of changes from the established best flight program. Then airline department has to manage daily operations aiming to reduce increasing cost when unpredictable events modify the programmed schedule execution. Addressing these objectives, Alitalia Operational Research Department has developed the Airline Recovery Model, the decisional support for the real-time management of irregular operations. Airline Recovery Model is built as a suite of optimization models for the Operations Control Center that aim at solving the problem of the operative irregularities by developing a global approach. After a general introduction with the problem description, the first section of this chapter presents Hub Recovery Model, to minimize the damage on the Origin-Destination passenger flows. The second section addresses Aircraft Recovery Model, to re-develop valid routings for each available aircraft of the fleet. The last section introduces the Crew Recovery Model, able to rebuild the crewmember pairings.
