Mechanism on Simulation Cloning Middleware of Performing Concurrent Multiple Scenarios

仿真克隆可以提高分布式离散事件仿真的效率和并行性,方便快捷地对仿真中的多种可能性进行分析、比较和评估。介绍仿真克隆的相关概念,分析HLA环境下封装式仿真克隆中间件的不足,提出并设计一种支持多剧情并发的拦截式HLA仿真克隆中间件,讨论基于该拦截式仿真克隆中间件的HLA仿真成员体系结构,并对联邦成员的时间延迟性能进行测试,测试结果表明该松耦合结构使联邦成员产生的时间延迟是有限且基本稳定的,基于拦截式仿真克隆中间件方法是可行的。

The efficiency and the parallelism of discrete event simulation can be improved through simulation cloning. Analysis, comparison and evaluation of what-if can be processed quickly and conveniently. Based on detailed introduction of simulation cloning and the analysis of the deficiency on encapsuled simulation cloning middleware, an articulated simulation cloning middleware of performing concurrent multiple scenarios is proposed and designed. The architecture of federate based on articulated simulation cloning middleware is discussed. Time delay of the federate based on articulated simulation cloning middleware is measured in experiment. The results demonstrate that the time delay caused by the decoupled federate architecture is limited and stabilized, indicating the feasibility of the method proposed.
