摘　　要：仿真克隆可以提高并行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。给出广义多方案分析仿真概念,介绍仿真克隆的相关概念,分析当前仿真克隆方法的不足,提出提高广义多方案分析仿真整体运行效率的异地克隆概念。基于检查点与恢复方法,在动态并行仿真引擎中实现了异地克隆。利用Phold测试程序对异地克隆方法的效率进行测试,测试结果表明,异地克隆可以提高多方案分析仿真系统整体运行效率。The efficiency and the parallelism of parallel discrete event simulation can be improved through simulation cloning. Analysis, comparison and evaluation of what-if can be processed quickly and conveniently. Generalized Multi-Scenario Analysis Simulation （ GMSAS ） concept was given. Based on the introduction of simulation cloning and the analysis of the deficiency on current simulation cloning, the out-place cloning was proposed to advance the efficiency of GMSAS. It was implemented on checkpoint/recover in dynamic parallel simulation engine. An experiment was carried out by using Phold testing program. The results of experimental research demonstrate that the whole efficiency of GMSAS system is improved through out-place cloning.
