摘　　要：采用HLA(High Level Architecture)的技术标准,可以将单个仿真应用或者模型连接起来组成一个大型的仿真应用。RTI(Run-Time Infrastructure)是HLA的程序实现。现有的RTI大多采用集中式的管理结构,当仿真节点数量增加、节点间进行频繁的数据交换时,仿真性能可能不具备容错能力。提出基于Web服务(Web Services)的RTI设计思想,设计策略中不仅解决了上述问题,而且解决了Web服务额外带来的管理和调度问题,并对一些关键问题提供了解决方案。最后通过实际测试证明了这种方案的可行性。Using High Level Architecture （HLA）, a large stimulation application could be built by connecting each single simulator. Run Time Infrastructure （RTI） is the implementation of HLA. The problem of fault tolerance may arise while increasing the number of simulation nodes and the data exchange among the nodes, since most of RTIs use centralized management currently, A design of RT1 was put forward based on Web Services. This design not only resolved the problems above, but also settled extra management and scheduling problem caused by Web Services. Also, some schemes were proposed to settle key problems in this design, Finally, the feasibility of this design was proved by tests.
