摘　　要：在信息化战争时代,OODA指挥控制环在军事仿真中的应用日益广泛,分布式仿真的灵活性及高效的并行性对作战仿真的发展提供了便利。面对作战仿真的需求,对分布式仿真系统的核心技术——时间管理算法进行研究。针对OODA指挥控制环的特点,提出了一种自适应移动时间窗算法。算法根据模型自适应调整时间窗大小,可避免频繁同步并对内存进行精准清除。为进一步优化时间管理算法,提出了一种改进全局虚拟时间算法,对全局虚拟时间同步计算中的阻塞过程进行改善。详细分析该算法的步骤及原理,并通过实例进行验证。结果表明,该算法可有效保证分布式仿真的运行,运行速度优于其他传统时间管理算法。In the information-based war era,OODA command and control loop is widely used in military simulation.The flexibility and efficient parallelism of distributed simulation promote the development of combat simulation.According to the requirement of combat simulation,this paper studies the core technology of distributed simulation system,which is time management algorithm.Based on the characteristics of OODA command and control loop,this paper proposes an adaptive moving time window algorithm.The algorithm adaptively adjusts the size of time window according to the model,which can avoid frequent synchronization and clear the memory accurately.In order to further optimize the time management algorithm,the author also proposes an improved global virtual time algorithm to improve the blocking process in global virtual time synchronization calculation.Through detailed analysis of the steps and principles of the algorithm,and verification by an example,the results show that the algorithm can effectively guarantee the running of distributed simulation,and the running speed is better than other traditional time management algorithms.
