Abstract
In order to promote a efficient utilization of local airport in Japan, an aircraftscheduling model for commuter services is discussed in this paper. The paper proposes a quadratic integer programming model and solved it by using the Hopfieldtype neural network algorithm which is expected to find out quasi optimal solutions. The validity, applicability, and tranferbility of the model was confirmed from a series of results. Moreover, several algolithms to get a better solution within realistic calculation time were proposed and tested.
