The invention discloses an HTCPN-based airport tractor dynamic optimization scheduling method. Aiming at the dynamic scheduling problem of the airport tractor, the invention designs a tractor dynamicscheduling simulation system based on a hierarchical timing coloring Petri net. After the randomness of each link in the operation process and possible pushout conflicts are considered, dynamic allocation of the tractors is completed according to pushout applications sent by the aircrafts in real time. On the basis of ensuring the minimum flight delay, the optimization targets of the highest working load balance degree and the shortest vehicle driving total distance among different vehicles are sequentially realized, and the effectiveness of optimization is verified through a Monte Carlo experiment. Finally, the system is used for completing the evaluation of the guarantee capability of the tractor of the target airport, and predicting the necessary tractor configuration number under different flight densities.
Description
technical field [0001] The invention belongs to the technical field of airport ground vehicle dispatching, in particular to an HTCPN-based dynamic optimization dispatching method for airport tractors. Background technique [0002] The rapid growth of air traffic has greatly increased the operating pressure on the airport scene. In large hub airports, delays caused by guaranteed vehicle dispatch accounted for 15.45% of all delays. At present, the tractors at most airports in my country rely on manual dispatching, and the staff dispatch qualified vehicles through visual and voice intercom. The outdated information acquisition methods and decision-making process lead to low dispatching efficiency during peak hours of flights, which in turn affects The punctuality of the flight. The problem of ground support vehicle scheduling continues to receive widespread attention from scholars at home and abroad, and the research methods mainly focus on two aspects: operations research met...
