The airline operational flight schedule consists of flights including their departure and arrival airports and times,
their day of operation, and the assigned fleet types, as well as assignment of specific aircraft and cockpit and cabin
crews. The scope of this paper is a daily operational flight schedule as complete plan with aircraft routing in a phase
of realization. Every day, during the realization of flight schedule some irregular operations are happened. The
dispatchers in Airline Operational Control Centre (AOCC) handle these problems caused by airport closures,
weather effects, or unscheduled maintenance, making flight rescheduling with goal to minimize negative effects of
disturbances. Flight delays, aircraft and crew swapping, flight cancellations, additional flights, using spare aircraft or
crew for realization of planned operations, etc. are the measures that dispatcher used to solve disturbance problem.
Dispatchers face with two problems: aircraft schedule recovery and crew re-assignment, taking into account all
constraints, factors and regulations, while trying to find solutions in a few minutes. The problem is to keep the
effects of disturbances as low as possible and to return to regular operations.
