AI Technical Summary
Existing technologies cannot accurately depict the true causal relationship between factors affecting flight ground support and support events, cannot quantify the real impact of different control behaviors on support efficiency, and are difficult to achieve globally optimal time-constrained decision-making throughout the entire support process, resulting in serious flight departure delays.
A causal reasoning-based approach is adopted. By constructing a hierarchical analysis system for flight ground support, a standardized quantitative reference dataset is obtained, a causal structure feasible region matrix is generated, a sparse causal adjacency matrix is learned, the causal strength of the intervention interval is calculated, a Markov decision process model is constructed, the globally optimal time constraint strategy is solved, and robustness verification is performed.
It has achieved accurate identification of the core driving factors of flight ground support efficiency, quantified the real impact of control behaviors, generated globally optimal time constraint strategies, improved flight punctuality and airport management level, and has robustness and generalization ability.
