摘要
国民经济动员仿真演练是一个复杂的基于HLA的分布式离散事件仿真过程,包括人在回路与无人在回路的混合仿真环节,且一次演练中参演单位数量非常多,需要解决高效的实时与超实时混合仿真控制问题。在分析仿真演练特点的基础上,将并行离散事件仿真(PDES)技术应用于联邦成员仿真控制过程,提出联邦成员离散事件仿真与成员内部PDES混合仿真策略。在分析时间推进过程的基础上,设计全局仿真时间控制机制。混合仿真策略可以支持实时与超实时混合仿真模式,并能充分地提高仿真并行能力,而全局时间控制则保证了系统时间的有效推进。
The national economy mobilization simulation training （NEMST） is a complex distributed discrete event simulation system based on HLA. Because it includes the man - in - the - loop simulation and the no man - in - the - loop simulation, and the quantity of mobilization entities are numerous during a training process, the problem of efficient real - time and faster - than - real - time hybrid simulation control has to be resolved. According to the simulation characteristics of NEMST, the parallel discrete event simulation （PDES） technology is applied to the simulation control of federate, a hybrid simulation strategy is proposed for the discrete event simulation of federate and the PDES inside federate. Then, a global time control approach is designed, by analyzing the time advance process. The hybrid simulation strategy can support a hybrid mode including the real - time simulation and the faster - than - real- time simulation, and improve the parallel simulation efficiency. The global time control can make the simulation time advance efficiently.
