Flight deicing delay mechanism and resource optimization configuration under complex and multiple constraints

Aiming at the frequent delays of deicing flights and extensive use of deicing resources in airport deicing operation, an optimal allocation method of deicing resources considering flight delay mechanism is proposed. The deicing efficiency affected by multi-parameters and the deicing queuing delay mechanism under dynamic random flight environment are studied. The complex multi-constraints of deicing operation are analyzed, and a multi-objective optimal allocation model of aircraft deicing resources is established, which aims at minimizing deicing fluid consumption, deicing vehicle demand and delays of de-icing flights. An adapt grid algorithm based on multi-objective particle swarm optimization(AGA–MOPSO) is used to solve the model and an optimal allocation method of de-icing resources based on multi-attribute decision optimization is proposed. After optimizing the allocation of deicing resources, the deicing fluid consumption,deicing vehicle demand and de-icing flight delay were reduced by 13.9%, 12.8% and 19.3% respectively compared with those before optimization. This method provides a new idea for the optimization of airport deicing operation resources.
