摘要
HLA虽然能够简化各类仿真系统的互操作和重用,但是接口规范与编程语言的绑定、缺乏与商业技术的融合等阻碍了它在商业领域的广泛应用,Web服务具有平台和厂商独立等良好特性,实现基于HLA分布式仿真的Web服务化能够将Web服务的优势附加给HLA。该文在分析了HLA不足和Web服务优势的基础上,提出了HLA Web服务化,对比了互操作在两个上下文中的差异,分析了实现HLA Web服务化的三个层次;之后,概述了相关研究,重点讨论了实现Web使能RTI的关键技术问题及其解决方案;最后,设计了原型系统,测试结果显示原型系统能够初步实现RTI的Web服务化。
HLA can facilitate the interoperability and reuse of all types of simulation systems; however, several drawbacks have affected its wide application in commercial communities, such as binding of interface specification to programming languages, and insuificient integration with commercial technologies. Web service has some attractive features on platform/vendor independence, and hence Web service enabling of HLA-based distributed simulation is promising for adding value to HLA. Based on the analysis of HLA＇s drawbacks and Web service＇s advantages, Web service enabling of HLA is introduced, interoperability on those two contexts is compared, and three levels of realizing Web service enabling of HLA are analyzed. Then, related research is surveyed, and key issues and their solutions to realizing a Web enabled RTI are discussed; Finally a prototype is designed, and experiments show that it can primarily implement Web service enabling of RTI.
