Abstract： 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.
