| 摘 要： | 高层体系结构(HLA)中的保守时间推进机制是以并行离散事件仿真(PDES)的保守算法为基础,而考虑不全面的时间推进算法会导致死锁。在维修保障仿真中,维修单元成员常常由于不满足保守算法而引起整个仿真系统无法向前推进。针对具有确定维修任务完成时间的成员不遵循本地因果约束条件的情况下,提出了强制时间同步法;针对具有不定维修任务完成时间的成员违反可预测性的情况下,提出了空事件法和任务阶段法。最终,通过实例验证了算法的正确性和有效性。

| Abstract: | Conservative time management mechanism of HLA is based on conservative algorithm in Parallel Discrete Event Simulation.Inconsiderate time advance algorithm can result in a deadlock.The support system federate often can not satisfy the conservative algorithm,so the whole federation can not be able to advance anymore.Force time synchronize algorithm was provided to result the support system federate which could not satisfy the Local Causality Constraint in fixed maintenance mission finish time.Null events algorithm and mission phase algorithm were provided to result the support system federate which could not satisfy the predictability in unfixed maintenance mission finish time.In the end,an example proves that the algorithm has relatively practicability. |
