摘　　要：基于HLA的分布式仿真已得到广泛的应用,但组建需要跨越组织或基于公共互联网通信的基于HLA的分布式仿真应用目前还较难实现。网格计算技术在资源协调、管理方面的优势为分布式仿真提供了新的发展空间。本文在回顾基于网格技术的仿真的发展研究前沿前提下,提出了基于网格服务实现HLA/RTI向Internet环境扩展的系统结构。系统结构在考虑融入网格技术优势之外,同时考虑到了仿真组件的可重用性、互操作性和兼容性等问题。原型系统仿真实验表明了系统结构的可行性。The HLA-based distributed simulation has been widely used, but presently it＇s difficult to implement a HLA-based distributed simulation application which needs resources from multi-organizations or communicates on the public Internet environment. The advantages of computational Grid in distributed resources collaboration and management provide a new development opportunity for distributed simulation. This paper reviews the present research situations of applying Grid technology to HLA-based distributed simulation, and then proposes a distributed simulation framework, which realizes extending HLA/RTI to Internet based on Grid service. The framework aims to the advantage of Grid technology as well as the reusability and interoperability of simulation modules. The results of experiments of the prototype indicate the feasibility of the framework.
