Abstract: According to the practical situation of aircraft delays in hub airports on snowy days and the current application of multi-deicing bays (MDB), aircraft queuing model of the MDB is established based on multi-server queuing system theory. Besides, the dispatch model of each corresponding holding deicing queue is also established based on game theory. The dynamic flights data of Beijing Capital Airport are used for simulation. The results show that the classification and fair allocation of the deicing bay can decrease the holding time of all the deicing aircrafts in the deicing system and relieve the deicing jam in peak hours, and the model guarantees the fairness of the deicing resources allocation and presents the relationship between MDB input and aircraft's sojourn time. This research also provides a new way for airports' deicing operation and deicing bay construction.
