基于时间不确定性的HLA乐观时间同步

在现有仿真时间推进机制中，事件的发生时间采用精确的时间戳，但是有时事件的发生时间用一个时间区间来表达更合理。该文提供了一种新的时间卷曲方法来发掘事件发生时间的不确定性，此方法的核心思想是：用事件的时间区间模型代替精确时间戳模型来提高事件并发性；当事件的时间区间重叠时用因果关系防止失序；对因果关系事件采用语义学方法进行区分，防止过多回滚。在RTI上增加时间管理扩展组件，用来实现基于时间区间的乐观时间同步机制。

Temporal Uncertainty Exploitation in Time Warp Simulation of HLA

Current works in distributed discrete event simulations depend on precise time stamps to events, but sometimes it is reasonable for modelers to use time intervals. This paper describes a time warp mechanism to exploit temporal uncertainty. The basic idea of the approach is to provide an event model in which events are assigned time intervals to exploit parallelism, a sub-mechanism to preserve causal ordering when time intervals to events overlap and a semantics sub-mechanism to prevent rollback too much, A component based on RTI is implemented, which ensures a practical time warp mechanism.
