摘　　要：实现全球资源共享是以网格为代表的新一代信息技术的主要目标,然而现有的分布式仿真资源远没有实现全球范围的共享,原因是缺乏对仿真资源统一的组织和管理,资源的可重用性不强,而利用网格和W eb服务有望解决该问题。该文分析了W eb服务、网格计算和高层体系结构HLA三者之间的潜在联系,设计了网格环境下以W eb服务为中心的分布式仿真资源框架,在该框架中所有仿真资源都封装为W eb服务。最后重点研究了HLA仿真系统中的联邦资源重用问题,对仿真服务的描述和仿真联邦的组合进行了深入的探讨和具体的设计,论证了方案的可行性。To achieve global resources sharing is the main goal of next - generation information technologies, especially the Grid. However, current distributed simulation resources （DSR） are far from being globally shared mainly because of the lack of an uniform organization and management of DSR. Tbe reusability is not strong enough. Grid and Web services are expected to solve these problems. This paper has studied the latent connections among Web services （WS）, Grid computing and High Level Architecture （HLA）, and designed a Web service -centered DSR framework under Grid environment, where resources are packed as WS. Further, we put our emphasis on the reuse of HLA federation resources, and deeply discuss WSDL description for simulation services and the composition of HLA federation in Grid environment. The feasibility of our work has been demonstrated.
