摘　　要：通航维修作业多为跨地域作业且作业时间多具有不确定性,这给通航维修资源的调度带来了一定困难。针对通航维修资源调度是一个典型的离散事件动态系统,结合Petri网模型理论,建立了基于着色和时间的高级Petri网维修资源调度模型,通过该模型用于维修资源的预调度,实现了调度时间预估、可视化调度状态查询。根据预估调度时间结合实际通航维修资源的状况,通过动态规划算法对维修资源进行合理分配,达到了保障飞机持续适航和提高维修资源利用率的目的,为通航维修资源的调度分配提供理论支持和应用参考。Navigation operations are mostly cross-regional, and the operation time is uncertain, which bring certain difficulties to the scheduling of navigation maintenance resources. As a typical discrete event dynamic system, this paper proposes a hybrid Petri network maintenance resource scheduling model based on coloring and time. This model can be used for pre-scheduling of maintenance resources, scheduling time estimation of relevant maintenance resources, and visual scheduling status query. Finally, the maintenance resource scheduling time of the output of the model calculation is combined with the actual situation of the actual general aviation maintenance resources, and the maintenance resources are rationally distributed through the dynamic programming algorithm to achieve the purpose of ensuring the continuous airworthiness of the aircraft and improving the utilization rate of the maintenance resources. This provides theoretical support and application reference for the scheduling and allocation of general aviation maintenance resources.
