摘　　要：并行离散事件仿真技术为复杂大系统的设计与研究提供了便利,该技术要求仿真程序在事件的因果约束条件下,正确、合理地推进仿真。仿真时钟管理及推进是影响并行仿真系统仿真效率的重要因素之一。通过对保守和乐观两种基本同步机制的对比性分析,研究和总结了仿真时钟的管理及推进的关键要素,研究结论对并行离散事件仿真系统具体的同步机制算法的实现具有一定的参考意义。Parallel discrete event simulation techniques make design and research on complex system easy. However, the event must be processed to ensure causal logic in a correct and reasonable order when simulation program is run . Simulation clock management and advance is the one of the important factors that affects simulation efficiency. This paper analyses conservative and optimistic synchronization mechanism, then researches and summarizes the key elements of simulation clock management and advance. These results are worthy of being used for reference in concrete algorithm application.
