HLA及其时间管理

高层仿真体系结构(HLA)作为新一代分布交互仿真的体系结构，在军用仿真方面有着广阔的应用前景。其中的时间管理是仿真模型所必需的，它描述了系统的时间特性，是仿真模型中仿真时间的推进机制；在介绍了HLA中所定义的时间管理服务的基础上，讨论了时间管理服务的需求及HLA中时间管理服务目前定义的设计原则；这些服务的关键之处是在联邦和运行支撑架构(RTI)软件之间的信息流动，从而使时间管理算法得以有效实现。

High Level Architecture and Its Time Management

High level architecture (HLA), which is a new architecture for distributed simulation, has found a wide application in military simulation. Time management in simulation to ensure temporal aspects of the system under investigation is correctly reproduced by the simulation model. This paper describes the time management services that have been defined, as well as design rationales that lead to the current definition of the HLA time management services. The most important part of these services is the information that flows federates and the Runtime Infrastructure (RTI) software in order to efficiently implement time management algorithms.
