摘　　要：RTI是高层体系结构HLA的软件实现 ,它为分布式交互仿真提供透明的服务。时间管理是影响RTI系统高效运行的重要因素之一 ,本文结合并行离散事件仿真思想 ,深入探讨了RTI时间管理算法。该算法从系统可实现角度分别研究了时间管理中LBTS计算、死锁检测与解锁、成员时间属性改变以及Lookahead值改变等的有关算法。应用结果表明该算法有效提高了系统运行的并发度 ,RTI系统性能也得以明显改进。As the software release of High Level Architecture (HLA), RTI offers transparent support for distributed interactive simulations. Time Management (TM) is one of the important factors that affect RTI running performance. A thorough investigation is carried on TM algorithm in this paper, which is inspired by Parallel Discrete Event Simulation (PDES). The proposed algorithm is designed for practical software implementation and includes LBTS computation, Deadlock checking and breaking, federate dynamic time attribute and Lookahead, etc. It is shown that our algorithm can enhance the system concurrence efficiently and improve RTI therefore.
