Abstract: Taking the airport de-icing resources optimization arrangements problem in winter as the research object and the utilization efficiency improvement of aircraft de-icing resource used as the target, a study scheme based on mixed scheduling algorithm is proposed to solve the problem of airport de-icing operation through analyzing the theory and method of airport de-icing process scheduling. On this basis, a mathematical model is built to maximize the use of de-icing resources, and the simulation and the comparative analysis of the model are conducted. The results show that the algorithm can make use of the de-icing resources more effectively in solving aircraft de-icing scheduling problem and can improve resource utilization efficiency better compared with the existing manual scheduling method.
