HLA数据回放及其可通用性问题研究

A Disquisition to General Purpose HLA Data Playback

为了给HLA分布仿真系统提供运行数据的回放能力并解决各种回放策略都必须面对的数据完备、时序准确、运行高效及回放方法的可通用性等问题,对HLA联邦中的数据回放问题进行了研究,分析了HLA仿真中的回放需求以及HLA对回放实现技术的影响,指出回放方法的可通用性实质上是联邦独立性的概念,研究了将回放数据对象化处理的方法,针对成员式数据回放策略、基于对象序列化技术和成员自动生成技术提出了一种可通用的HLA数据回放实现方案,最后介绍了通用HLA数据回放工具的应用情况。

For supplying the capability of replaying the HLA federation execution data and solving the issues demanded by playback that data must be integrated as a whole,time order must be exactly,run efficiency should be highly and the solution should be general-purpose,this paper explores the issues of data replaying in HLA federation,analyzes the requirements and the impacts of HLA on playback,points out that the essentially general purpose is a concept of federation independent,and excogitates a data processing method to deal with the replayed data by means of object.Relying on the strategy of a concentrated playback federate,the playback solution was putted forward,which is based on the technology of data's object serializing and federates' automatic-generating.The solution realizes the goal to make a general purpose data playback.In the end,this paper introduces the application of the general-purpose playback tool.
