A-SMGCS航空器滑行时间延迟的滑行路由实时更新算法

在先进场面活动引导和控制系统(advanced surface movement guidance and control systems,A-SMGCS)中,针对航空器滑行时间延迟而导致场面运行效率和安全水平的降低,提出一种集成场面态势监测的滑行路由实时更新算法。该算法采用局部路由更新方式,首先采用时间窗约束Petri网建立航班滑行时间延迟时的场面局部模型;其次,定义模型中库所对应时间窗的合并运算规则;并据此展开局部模型约简,进而得到约简模型中航班滑行冲突判定条件;再次,以最小化航班在冲突区域的滑行成本为目标,实现了相关航班局部滑行路由优化同时保证了对原路由扰动最小;最后,通过算例验证了所提滑行路由实时更新方法的有效性。

Taxi Routing update algorithm for A-SMGCS with taxi time delay

In airport operation process, aircraft taxi time delay will lead to operation efficiency and safety level degrades. To solve this problem, an algorithm integrated surface monitoring is proposed. The part routing update strategy is adopted and the time window constrained Petri Net is used to model the surface operation when aircraft taxi time delay. Secondly, the time window combination rule for Places in this model is provided, and the model is reduced to a simplified model. In this model, the aircrafts taxi conflict conditions are derived. Thirdly, the aircraft taxi routing update is fulfilled with the purpose of minimizing taxi cost and disturbance to the old routing; Finally, the validly of the proposed taxi routing update algorithm is proved by experiment.
