Abstract
On-time performance of airlines schedule is key factor in maintaining current customer satisfaction and attracting new ones. This requires management of the different operation resources (crew/aircraft) to ensure their on-time readiness for each flight in the planned schedule. However, flight schedules are often subjected to irregularity and needs rescheduling. This process is done by operator's knowledge which is cultivated from his long experience. This paper describes the modeling of flight rescheduling. In addition, this proposes the evaluation of flight scheduling to evaluate the flight plan which the operator made.
