Abstract
It is a well-known fact that punctual flights of airlines result in high customer satisfaction. However, the flights are frequently delayed or canceled due to unexpected incidents. These incidents are to be dealt by rescheduling, which intends to maintain a high level of customer satisfaction while adjusting resources involved. Rescheduling is a highly complex problem, because of large number of resources involved and existence of some candidates of possible plan. Today, the flights are rescheduled by operator's implicit knowledge which is cultivated from his/her long experience. For these reasons, a computational support method of rescheduling of flight service is strongly desired to support the difficult rescheduling decisions. This paper proposes a decision support method of flight rescheduling. In order to visualize an analyze the system of flight service, this paper represents flight services as a service model consists of three sub service models: (1) transportation service, (2) operation service, and (3) maintenance service. This paper also proposes an algorithm of the rescheduling based on the flight service model, and evaluation method of flight plans to support operator's decision making. Proposed service model and evaluation method is applied to actual data of flight services as a case study. The result shows practical effectiveness of propositions.
