Simulation Resources Management, The Level Of Research, The Sharing Mechanism

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.
