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.
