Research On Constructing Principle And Implementing Technology Of Resource Sharing Service Platform For Networked Manufacturing

As a kind of advanced manufacturing paradigm in network economy and knowledge economy environment, networked manufacturing (NM) emphasizes inter-enterprise collaboration and resource sharing in the whole society. The goal of NM is to improve the innovative capability of product designing and to realize the lower cost and higher efficiency of product designing and manufacturing process. Therefore, the share and optimized utilization of manufacturing resources dispersing in enterprises through network is one of important characteristics of NM. The resource sharing service platform that can integrate all kinds of resource and provide all kinds of function will become one of important technically enabled tools for NM, and will effectively support implementation of NM in enterprises.Based on analysis of domestic and international researching achievements for NM, the functional architecture of resource sharing service platform for NM has been put forward in the dissertation. Some key technologies for implementation of resource sharing service platform have been researched in depth, which are modeling, acquisition and integration of resource in NM mode, integrated management of information for manufacturing enterprise, integration of application system in virtual enterprise based on Web service, networked manufacturing service technology based on application service provider (ASP) mode, inter-enterprise collaborative work based on shared resources and data mining (DM) for enterprise decision-making. As the verification of feasibility and practicability, the development and preliminary application of a prototype system is also discussed. These research works make active exploration for resource sharing and service technology in NM mode of Chinese manufacturing industry. The main characteristics and creative ideas of the dissertation are as follows:(1) The functional architecture of resource sharing service platform for NM is put forward. Supported by shared resources in common data center, the platform will provide services of integration and management of resource, support for inter-enterprise collaborative work,networked manufacturing service, registering center enabled by UDDI, and maintenance and safety control of shared resources for allied enterprises by utilizing application toolkits. Based on analysis of key implementing technologies of service platform, a prototype system of service platform, which mainly consists of functional modules of common data center, tele-collaborative designing center, and tele-manufacturing service center, has been developed.(2) The resource model for NM based on resource sharing service platform is presented by applying object-oriented resource modeling method and multi-Agent technology. The method of manufacturing resource acquisition based on semantic Web technology is studied, and integration and rapid reconfiguration of resource in NM environment is expounded. The resource acquisition and integration model for NM is put forward supported by resource sharing service platform.(3) Based on analysis of integrated management technology of information for manufacturing enterprise, the Web-based integrated management system for process information, which mainly includes the management of project, process file, process resource, document, tooling, task and man-hour, has been studied and developed. The integration and share of process information among different departments in an enterprise is realized.(4) Because members in a virtual enterprise and their application systems change frequently, a flexible workflow management technology for virtual enterprise based on Web service has been presented by thoroughly analyzing technical framework of Web service. The integration of application systems in virtual enterprise is realized, and the flexibility and adaptability of workflow management in allied enterprises is improved.(5) Aiming at the feature of finite element analysis (FEA), a technical solution of establishing FEA tele-service system based on application service provider (ASP) mo...
