HLA仿真系统中Lookahead的分析与动态调整策略

在HLA仿真系统中，Lookahead是影响系统性能的重要参量，对Lookahead的管理也是实现邦元程序的重要内容。采用时间分段的方式重新定义HLA仿真系统中的Lookahead，很好地解决了仿真运行中时戳增量改变较大的问题。在此基础上提出的Lookahead动态调整算法考虑了邦元程序对要接收事件的经验值，可以有效提高系统运行性能，协助邦元程序设计。

The Exploration and Dynamic Regulation of Lookahead in HLA Distributed Simulation Systems

Lookahead is an important parameter in concert with system performance in HLA simulation systems. The configuration of lookahead value is also an important part in the implementation of federate programs. The redefinition of Lookahead by dividing the simulation time into segmentation is a creative way in HLA simulation systems, which solves the fluctuation problem of timestamp increment in runtime. The design of algorithm of dynamic regulating lookahead is based on the received events knowledge of federate entity. It can improve the system performance and help the program design using this algorithm.
