【摘要】 HLA是当前军事电子信息系统仿真领域应用最广泛的体系架构,但HLA还存在许多遗留问题没有解决,它已经不能满足军事电子信息系统仿真的需求。面向服务体系结构SOA,以服务和共享为核心,基于开放的标准和协议,具有松散耦合的特点,有利于系统间互操作和组件重用,对于构建复杂军事仿真系统而言,无疑是一种很好的解决方案。因此,HLA势必要被基于SOA的网络化建模与仿真技术所取代。鉴于HLA的不足和SOA在军事仿真中的应用潜力,本文提出了基于SOA的军事电子信息系统仿真架构(SOA-MEISSF),主要解决广域网范围内仿真系统间的互操作,提高仿真组件的重用性以及基于仿真服务快速重组仿真系统等问题。本文全面论述了可以应用在军事仿真中的架构思想(HLA、SOA和MDA)及面向服务体系架构的几种实现技术(CORBA、DCOM和Web Service)。在深入理解SOA相关知识并考虑军事仿真应用的需求和特点的基础上,提出了SOA-MEISSF模型。文中对架构模型的各个层次做了深入的分析,并详细阐述了仿真服务体系的层次划分及各层服务的设计重点,论述仿真服务的实现及封装原则。SOA架构的实现是由一系列开放技术作支撑的,本文认为模型驱动架构MDA是适用于基于SOA的仿真系统开发的有效方法,Web Service技术是实现SOA的一种最可行的技术途径,基于这种思路,本文给出了利用MDA方法和Web Service技术来开发基于SOA的仿真系统的过程模型。最后,基于SOA-MEISSF模型,本文给出了雷达情报综合处理仿真系统原型的设计与实现。更多还原

【Abstract】 HLA is the most popular architecture used in simulation for military electronic information system. But there are many unsolved problems in HLA standard which results in the deficiency for requirements of military simulation. The kernel of Service-Oriented Architecture (SOA) is service and share. It based on open standards and protocols, has the loose-coupled characteristic which is useful for interoperability of system and the reuse of components. And no mistake, SOA is an excellent method for constructing complex military simulation system. So HLA will be replaced by the technology of SOA-based network modeling and simulation.In view of the deficiencies of HLA and the application potential of SOA in military simulation, a SOA-based military simulation system framework (SOA-MEISSF) was proposed in this theis. The framework solves the interoperability among simulation components in the WAN, improves the reuse of simulation components and recombines simulation system based on simulation services quickly.The idea applied in military simulation (HLA, SOA and MDA) and some implement technology (CORBA, DCOM and Web Service) for service-oriented architecture is analysed in the theis. With the deeply thinking of SOA and considering the requirement and characteristic of military simulation system, we propose SOA-MEISSF. And each level in the framework is explained after. Then the theis discusses the levels and design of simulation services system. Later we explain the implement and encapsulation principle for simulation services. The implement for SOA needs serials of opening technologys. We think Modeling Driven Architecture is an effective method which is appropriate for developing SOA-based simulation system. And Web Service is most viable technical approach for SOA’s implement. With the thinking, the process model of developing SOA-based simulation system using MDA method and Web Service technology is presented in the theis.At last, the design and implement for a simulation applying system about dealing with radar information based on SOA-MEISSF is given.更多还原
