Robust airport parking space distribution method and system based on index tree, and medium

The invention relates to the technical field of aviation, in particular to a robust airport stand distribution method and system based on an index tree and a medium, and the method comprises the following steps: inputting flight operation data into a statistical model, and obtaining a flight conflict probability; based on a parking space allocation rule, taking weight maximization of flight and parking space allocation and probability minimization of parking space conflict as targets, and establishing a parking space allocation multi-target mixed integer programming model based on stochastic programming; adopting heuristic search, and searching to obtain index tree parameters based on the historical data of aircraft position distribution; and taking the flight plan and the index tree parameters as the input of the multi-target mixed integer programming model for aircraft position distribution for solving. According to the invention, the volatility of the flight time is introduced, the flight conflict can be r
