A Collaborative Optimization Model for Ground Taxi Based on Aircraft Priority

Abstract EN

Large hub airports have gradually become the “bottleneck” of the air transport network.

To alleviate the “bottleneck” effect, optimizing the taxi scheduling is one of the solutions.

This paper establishes a scheduling optimization model by introducing priority of aircraft under collaborative decision-making mechanism, and a genetic algorithm is designed to verify the scheduling model by simulating.

Optimization results show that the reliability of the model and the adjusted genetic algorithm have a high efficiency.

The taxiing time decreases by 2.26% when compared with an empirical method and the flights with higher priorities are assigned better taxi routes.

It has great significance in reducing flight delays and cost of operation.
