  • 摘要:
    目的 针对多波次舰载机保障调度中多类型对象关系复杂、资源竞争频繁以及作业依赖紧密等问题,需构建能够兼顾跨波次资源协调与局部任务优化的调度方法,并提升策略在动态作战环境下的快速适应与泛化能力。
    方法 提出元学习增强的异质图保障调度方法(Meta-HGS)。首先构建舰载机−保障作业−保障站位三元异质关系图,采用异质图注意力网络对节点类型及关系类型进行差异化建模,从波次级、任务级和资源级3个粒度聚合特征,实现跨波次资源竞争与作业时序约束的统一优化。引入元学习机制,设计Meta-Critic与Task-Actor编码网络,在多任务分布下通过内外循环参数更新实现策略的快速迁移与收敛。
    结果 在3类不同规模的实验场景中,Meta-HGS相较对比算法使保障完工时间缩短约5.4%,在实时性与解精度上亦保持优势,结果与OR-Tools的平均差距控制在2.3%,展现出更高的效率与稳定性。
    结论 基于Meta-HGS的调度方法能够有效刻画多粒度异构关系,显著提升多波次舰载机保障调度的效率与实时性,并具备较强的任务迁移能力与环境适应性。该方法为高动态、高耦合保障场景下的智能调度提供了可推广的技术路径。

     

    Abstract:
    Objective To address the challenges in multi-sortie carrier-based aircraft support scheduling, including complex multi-type object relationships, frequent resource competition, and tight task dependencies, this study aims to develop a scheduling approach that balances cross-sortie resource coordination with local task optimization, while enhancing rapid adaptability and generalization in dynamic combat environments.
    Method A meta-learning enhanced heterogeneous graph scheduling method (Meta-HGS) is proposed. A heterogeneous tripartite graph consisting of carrier-based aircraft, support tasks, and support stations is constructed, where a heterogeneous graph attention network is employed to model node types and relation types differentially. Features are aggregated across sortie-level, task-level, and resource-level granularities, enabling unified optimization of cross-sortie resource competition and task temporal constraints. To further enhance adaptability under dynamic task distributions, a meta-learning mechanism is incorporated, comprising a Meta-Critic network for cross-task value evaluation and a Task-Actor encoding network to extract task-specific policy representations. The Meta-HGS framework uses inner- and outer-loop parameter updates to achieve fast policy transfer and convergence across different tasks. Additionally, the HGAT explicitly models heterogeneous node interactions and meta-path-based neighbor aggregation, preserving semantic information of task-task dependencies and task-station assignments. This integrated approach allows the model to handle complex multi-type object relationships, frequent resource competition, and tightly coupled task dependencies, ensuring stable and efficient scheduling across diverse and dynamic operational scenarios.
    Results In three different-scale simulation scenarios, Meta-HGS reduced the average completion time by approximately 5.4% compared to GA, PSO, DQN, and G-A2C, while maintaining advantages in responsiveness and solution accuracy. Completion times for small, medium, and large scales were 42.1, 68.4, and 95.3, outperforming other methods by 1.6%–12.3%. Average response time (ART) and scheduling time (AST) remained the lowest, with ART at 45.3, 78.5, 156.2, and AST at 128.5, 256.3, 512.8, exceeding learning-based methods. The gap to OR-Tools’ optimal solutions was only 1.5%–3.1%, demonstrating high precision and stability. Memory usage was slightly higher than heuristic methods but comparable to DQN and G-A2C, supporting overall performance gains. Results indicate that Meta-HGS balances efficiency, real-time performance, and accuracy, providing an effective and robust solution for multi-wave carrier aircraft support scheduling.
    Conclusion The Meta-HGS-based scheduling method effectively captures multi-granularity heterogeneous relationships, significantly improves the efficiency and timeliness of multi-sortie carrier-based aircraft support scheduling, and demonstrates strong task transferability and environmental adaptability. This approach provides a generalizable technical pathway for intelligent scheduling in highly dynamic and strongly coupled support scenarios.
