为解决运行阶段场面滑行路由调整计算量大,难以满足A-SMGCS系统实时性需求的问题,建立了面向机场滑行资源的着色Petri网模型,提出把路由抽象成航空器对路段的访问优先级,通过降低优先级对延迟航空器进行惩罚实现路由调整。对调整优先级后可能导致的两类场面滑行冲突:对头冲突和循环等待冲突,通过分析模型中链路和回路等特殊结构特性,给出无冲突滑行充分条件及优先级调整策略。算例研究表明:本文方法能有效实现滑行路由无冲突调整,算法耗时小于10 s,满足A-SMGCS系统对路由规划时间的要求,控制规则简单,适用于实时控制。

Adjustment of airport taxiing routes in operation phase of aircrafts needs a large amount of calculation,which makes it difficult to meet the real-time requirements for A-SMGCS (advanced surface movement guidance and control system). In order to resolve this problem,a colored taxiway-oriented Petri net model was built and a method of aircraft taxiing routes adjustment was proposed. The method abstracted taxiing routes to the visiting priorities of aircrafts on a road section. The delayed aircrafts were punished by decreasing the priorities to visit the road section. To change priorities of aircrafts might lead to two kinds of conflicts:head-on conflicts and circular wait conflicts. Sufficient condition and priority change strategy of aircrafts conflict-free taxiing were proposed to solve those conflicts by analyzing the special structural characteristics of cycle chains and circuits of the colored taxiway-oriented Petri net model. An application example shows that the proposed method can avoid conflicts in aircrafts taxiing routes adjustment. The computation time is less than 10 s,which meets the planning time requirements of A-SMGCS. The control rules are simple,effective and suitable for real-time control.
