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.
