作战分析仿真是以各类战争活动为研究对象,以辅助各级决策为目的的一类仿真系统,其最典型的表现形式就是各类“方案”。由于其反复计算和时间紧迫性的特点,“超实时”计算是该类系统必须要具备的关键能力。并行/分布式仿真技术被认为是高性能作战分析仿真的必由之路。以PDES为代表的并行和以HLA为代表的分布式仿真平台在此类系统中都得到了一定的应用,取得了一些进步,也获得了一些经验教训,人们对它们谁更适合用于构建作战分析仿真系统争论较多。介绍了作战分析仿真的特点,阐述了并行/分布式仿真的基本原理,比较了PDES和HLA的基本结构,并从模型组织和运行方式两方面对二者进行了详细对比,深入分析了造成它们性能差异的根源,最后提出了基于BOM组件的并行作战分析仿真解决方案。
Combat analysis is a type of simulation system that takes all kinds of war activities as the research object and aids the decision-making at all levels. The most typical manifestation is all kinds of “plan”. Because of its recalculation and the urgency of time, “ultra-real-time” computing is a key capability that such systems must have. Parallel / distributed simulation technology is considered as the only way of high-performance combat analysis and simulation. The parallel simulation represented by PDES and the distributed simulation platform represented by HLA have all been applied in such systems. Some progress has been made and some lessons have been gained. People are more suitable for them to construct battle Analysis of simulation system more controversial. This paper introduces the characteristics of combat analysis and simulation, expounds the basic principle of parallel / distributed simulation, compares the basic structures of PDES and HLA, and compares the two in detail from the aspects of model organization and operation mode. The root cause of the performance difference, and finally put forward a BOM-based parallel combat analysis simulation solution.
