【摘要】 本文围绕仿真资源的管理和共享机制问题,从理论和实践两方面进行了研究。总结了实现仿真资源管理与共享的几个关键问题,并对所涉及的标准化问题和技术实现问题进行了研究。 首先,本文定义了仿真资源及仿真资源管理与共享的基本概念,对仿真资源进行了初步分类和划分。在此基础上,本文提出了实现仿真资源管理与共享所必须要解决的三个关键问题,即:管理与共享的政策和机制问题,管理与共享的标准化和规范化问题,集中与分布相结合的管理与共享体系建设问题。 仿真资源管理与共享的标准化和规范化中首先要解决的是仿真资源的分类和元数据标准问题。元数据是用来描述仿真资源的各种属性和获取方法的数据。本文给出了元数据的概念和应用方法。对数据字典技术也进行了介绍。 仿真资源信息管理和共享系统基于Web和分布式数据库技术,用户从任何地点通过广域网络就可以访问仿真资源管理与共享站点,利用标准的网络浏览器就可以进行仿真资源信息的浏览和查询。本文对这种信息系统整体和其主节点(又可称为网络中心或信息中心)进行了详细的设计,包括其体系结构、软硬件组成、系统功能模块、管理方法、工作流程、分节点之间的协作模式等,并对其中所应用的关键技术进行了详细讨论,对用户管理、访问控制等问题也进行了深入的探讨。 最后,本文设计和实现了“仿真标准管理与共享示范系统”。它利用了web和数据库技术,通过网站的形式对仿真标准文档进行管理,向用户提供仿真标准文档的查询和下载。
【Abstract】 This dissertation studies the mechanism of simulation resources management and sharing in both theoretical and practical ways. It identifies the key issues involved and addresses the standardization and technology problems essential to simulation resources management and sharing.In this dissertation, besides the concepts of simulation resource and simulation resource management and sharing, the basic classification of simulation resources is also given. This dissertation identifies the three key problems in management and sharing of simulation resources, that’s the establishment of the principles and policies, the standardization, and the building of the actual platform to manage and exchange simulation resources.The classification and standardization of meta data are the most important issues in simulation resource management and sharing standardization. Meta data is used to describe the properties of simulation resources as well as access methods. This dissertation gives the concepts of meta data as well as the application mechanism. Data dictionary is also discussed in it.The simulation resource management and sharing system is based on web and distributed database technologies, which provides users with access to all the nodes in the system via Internet, and the ability to browse and search for simulation resources by a standard browser. This dissertation gives the detailed design of the overall system and its main node, including the system architecture, software and hardware configurations, functions and components, management mechanism, working procedures, cooperation mode of multiple nodes, etc. The key techniques and the strategies of user management and access control are also discussed in detail.At last, this dissertation gives the design and realization of a demonstrative simulation standards documents management and sharing system. This system uses web and database techniques to manage simulation standards documents, providing users with the ability to browse, search for, and download simulation standards documents.
