Abstract

The invention relates to a method for solving a sliding path optimization index by using a Monte Carlo algorithm. The method comprises the following steps: generating a collection sample; obtaining prior probability distribution at the moment k; obtaining posterior probability distribution; screening the data information conforming to the optimal path; performing position state information resampling on the cells by using the estimated posteriori probability distribution function and a Monte Carlo algorithm; and performing simulation processing. According to the method for solving the slidingpath optimization index through the Monte Carlo algorithm, the sliding waiting time of departure aircrafts is shortened, the sliding efficiency is improved by 9.8%, and airport ground resources are fully dispatched and reasonably distributed.

Description

technical field [0001] The invention belongs to the field of airport surface transportation, and in particular relates to a method for solving an optimization index of a taxiing path based on a Monte Carlo algorithm. Background technique [0002] In recent years, with the continuous increase of airport traffic flow and the number of airport flights, the contradiction between my country's airspace system capacity, air traffic flow and air traffic management capabilities has gradually intensified, resulting in a continuous decline in the anti-interference ability of air traffic. Shipping delays are frequent and airline and passenger satisfaction is down. Therefore, the adjustment and optimization of airport operation management methods has also become an important way for our country to deal with large-scale flight conflicts. Due to the shortage of airspace resources, limited airport expansion, and limited airport infrastructure, optimizing variable taxi time to make full use ...
