英文摘要：

With the progressive increase of the distributed simulation size and rapid development of the high pertbrmance computing technology, the parallel and distributed simulation is gradually becoming the new research focus. Time management mechanism is the one of the key technologies which determines the correctness and repeatability of the parallel and distributed simulation; furthermore it directly influences the holistic performance of the simulation system. Most of the ideas and concepts of Time-Warp optimistic time management mechanism continue to be used and referenced by current various algorithms. Finally, a performance analysis model for Time-Warp system was constructed, and the number of processed events, average rollback length, rollback probability and its upper bound were analyzed. The analysis results have instructive signification and reference value for the future research and enhancement of the PDES simulation system.
