It is a useful tactic that punctual flight services result in high customer satisfaction to against low cost carrier. However, today about 50% of flights are frequently delayed or canceled by unexpected incidents. These incidents must be dealt by rescheduling to maintain a high-level customer satisfaction. Rescheduling is a highly complex problem since flight services have a large number of elements which are directly or indirectly involved in each other. And it is always dealt by operator's implicit knowledge which is cultivated from his/her long experience. For these reasons, a flight rescheduling support system is strongly desired to support the difficult rescheduling problems. Our research proposes a support system of flight rescheduling. This system represents flight services as a service model consists of three sub service models: (1) transportation service, (2) operation service, and (3) maintenance service. Based on the modeling of flight services, we focus on the relationships of flight services to describe the rescheduling of flight services. Our research also proposes an algorithm of flight rescheduling by using these relationships. Then an automatic planning and evaluation method for the flight rescheduling results is proposed to support operator's decision making. At last, the proposed flight rescheduling support system is applied to an actual data of flight services as a case study. The result shows practical effectiveness of our propositions.
