基于Agent的分布仿真中的时间同步机制

介绍了基于Agent的分布仿真平台ADSimE中采用的时间同步机制——保守策略和乐观策略，即在该平台中的节点内部采用保守策略，而在节点之间采用乐观策略，这样可提高仿真平台时间推进的性能。给出了两种同步机制的基本原理，重点阐述了保守策略仿真Agent类和乐观策略仿真Agent类的设计及处理流程。

Time synchronization mechanism in Agent-based distributed simulation

The time synchronization mechanism is one of the key problems on Agent-based distributed simulation research. The time synchronization mechanism of Agent-based distributed simulation environment (ADSimE) — conservative mechanism and optimistic mechanism were introduced. That is, the conservative mechanism was used within the node of the platform，while optimistic mechanism was used between the nodes. This kind of time synchronization mechanism could promote the performance of the time advancing in the simulation platform. The principles of the two mechanisms were also introduced. Finally, the key process of the design and running for conservative simulation Agent and optimistic simulation Agent were described in detail.
