为了解决对机场实际运营中存在的共用同一中间机坪滑行道的航空器相对推出型冲突问题,文中根据时间有色Petri网的相关理论,分析了导致机场的运行效率降低的航班的推出问题,结合成都双流国际机场的相对推出型廊桥,提出了基于时间有色Petri网(Timed-Colored Petri Net,TCPN)的复杂情况下航空器推出模型。依据此模型将航空器从滑行道到停入机位的全过程进行模拟和说明。最后结合TCPN仿真软件CPN Tools中的状态空间分析法,对模型的可行性进行分析,对保障航班推出过程的运行安全、提高繁忙机场的运行效率具有重要的现实意义。
In order to solve the problem of the relative push-out type conflict of the aircraft sharing the same middle apron taxiway in the actual operation of the airport, this paper analyzes the issue of the flight which leads to the reduction of airport operational efficiency according to the related theories of time-only Petri nets. The relative launch gallery of Shuangliu International Airport proposed an aircraft launch model based on the timed-colored Petri Net (TCPN). Based on this model, the simulation and explanation of the whole process of the aircraft from the taxiway to the parking position are described. Finally, combining the state space analysis method in TCPN simulation software CPN Tools to analyze the feasibility of the model has important practical significance to ensure the operation safety of the flight launch process and improve the operational efficiency of the busy airport.
