摘　　要：为推进并行离散事件仿真技术在复杂制造仿真系统中的应用,提高仿真效率,针对制造系统仿真模型,研究和实现了一种基于时间窗的受限滞后保守同步策略。阐明了策略的思想,具体分析了策略中距离矩阵、关联矩阵、时钟推进等关键要素,给出了策略的实现流程。实践表明了该同步策略具有建模容易,仿真效率高的特点,为仿真模拟复杂制造系统提供了较好的同步机制。To more effective apply parallel discrete event simulation techniques in complex manufacturing simulation system and improve simulation efficiency. With building a specific simulation model of manufacturing system, a conservative synchronization algorithm based on conservative time window is studied and carried out, then some key elements of the algorithm are analyzed, such as distance matrix, correlation matrix, simulation clock, etc. In the end, the system flowchart is expounded. In practice, convenience and high simulation efficiency are characteristic of this strategy. As a good synchronization mechanism, this strategy is applied in complex manufacturing simulation systems.
