为了提高HLA(high level architecture,高层体系结构)仿真联邦的时间管理性能,研究了时间管理性能的影响因素。首先,提出了着色交互Petri网,建立了HLA的时间管理模型,并在该模型的基础上应用Stateflow建立了HLA时间管理性能测试平台;然后,应用该测试平台研究HLA步进联邦中计算负载、前瞻量、步长等几个主要因素对时间管理性能的影响,获得了提高HLA步进联邦时间管理性能的一般结论;最后,通过在水声对抗仿真系统中的应用,验证了结论的有效性。
To improve the time management performance of HLA federation,this paper studied the influencing factors of time management performance.Firstly,proposed the colored interaction Petri net,and built the HLA time management model.Then,based on the model,realized the testing platform for HLA time management performance with Stateflow.Thirdly,analyzed the influencing factors such as load,lookahead and step by the platform,and obtained several general conclusions to improve the time management performance of time stepped HLA federation.Finally,validated the conclusions in acoustic counterwork simulation system,which proved the effectiveness of the conclusions.
