摘要
针对先进机场场面引导与控制系统(A-SMGCS)中滑行道运行控制建模,提出一种基于扩展层次Petri网(EHPN)的建模方法。将滑行道分为交叉口和直线段模块,然后对模块内部的航空器行为进行封装,形成基于扩展Petri网的过程层通用模块,并进一步采用同步合成技术建立过程层模型。利用面向Agent的着色赋时Petri网建立决策层通用模块,同时将场面运行控制知识与模块的库所和变迁集成,增强模型的智能决策能力。采用某机场12h滑行道运行数据进行了仿真试验。研究结果表明:基于EHPN模型的仿真,其直线段和交叉口冲突次数分别为6次和11次,滑行道系统总延误为346s,与SIMMOD仿真模型效果相近,因此,该建模方法有效。
For the modeling of taxiway operation control in advanced surface movement guidance and control system（A-SMGCS）,an extended hierarchical Petri net（EHPN）-based method was proposed.The taxiway system was divided into intersection and line segment modules.Aircraft behaviors in the two modules were encapsulated,and extended Petri net（EPN）-based generic modules were formed.The process layer model was constructed by using synchronizing composition techniques.An agent-oriented colored time Petri net（AOKCTPN）modeling approach was used to establish generic decision-making module.The operation control knowledge of taxiway was integrated into places and transitions,and the intelligent decision-making ability of decision-making layer model was enhanced.The taxiway operation data of some airport in 12 h were used to conduct simulation.Analysis result indicates that the conflict numbers in taxiway line segment and intersection are 6 and 11 respectively,and the total delay of taxiway system is 346 s.The result is relatively consistent with that of SIMMOD model,so the EHPN-based method is feasible.3 tabs,6 figs,11 refs.
