【Abstract】 The networked manufacturing (NM) as an advanced mode, is rising to the challenge of the knowledge economy and the manufacturing globalization, and it is to realizes the quick response to market demand and enhance the competitivity of enterprises. Networked manufacturing integration platform (NMIP) is an inter-enterprise cooperation sustaining environment, which provides support for NM with functions including base software and hardware environment, correlation protocols, common services, key tools and system management.NMIP also provides the transparent, unanimous information accessing and mutual operating means for inter-enterprise information integration, process integration and resource share. So it shall be emphasized to study networked manufacturing integration platform, including related theories, software platform and tools system for their theory significance, application value and industrialization development.Sponsored by China nation 863 C1MS topics: Guanzhong Region Networked Manufacturing Integration Platform Development and Application (No.2002AA414060 - 1), this thesis is created to sustain the NM applications, and in depth research some key technologies in regional NMIP including VPN, XML, Web services, WSRF, manufacturing resource modeling and encapsulation, application system integration, NMIP portal developing, manufacturing knowledge retrieval, etc. Guanzhong Region NMIP is finally developed on theoretical basis.The main research work and contribution of the thesis are as follows:Studying function requirements and characteristic of NMIP, the author built up a 6-layer NMIP structure based on the point of view of SOA. In this part the research provided a solid theory foundation for NMIP analyzing, design, implementing and maintaining.Classifying manufacturing resource based on the 0-0 method, the author established manufacturing resources layer structure model, and proposed the Manufacturing Resource Encapsulation method based on WSRF. By this, manufacturing resource is encapsulated into a WS-Resource architected resource through stateful resource encapsulation, which shields complexity and heterogeneous of manufacturing resources effectively. Manufacturing resource can be shared and collaborated conveniently by NMIP web services issuing.According to the requirement of NMIP portal, the author built up the layer architecture of portal and WSRF-based Single Sign-On (SSO) strategy to deal with the characteristics of NMIP authentication, and expounded its design ideology. This method realized authentication and authorization in the dynamic loose-couple environment, and solved the difficult problem of resource-grade authorization. Furthermore, the author detailedly studied other key technologies in NMIP, including modularization portal design, access control system based on role, service navigation system and database design. All those methods have their original view.Having analyzed the characteristic and requirement of the NMIP application system integration, the author proposed networked manufacturing application system integration architecture based on Web Services, and in detail analyzed Web Service application integration affair management engine and SOAP router key technologies with arithmetics.By studying the requirement of the NM application system integration, it was forwarded for the resource in enterprise and the application integration inter-enterprise sharing framework based on WSRF. Its design ideology and functions were also demonstrated. This system provided a new way to solve connection problems in Regional Networked Manufacturing.According to the requirements of NMIP knowledge retrieval, a semantic-based NM knowledge retrieval architecture was proposed. This frame offers a series of tools for supporting the knowledge share and promoting networked manufacturing cooperation. A model of semantic information search based on five-element-array was also created with its realization arithmetics. Correspondingly a test process of five-tuple array retrieval model was given. A practical way is thereby created to solve connected problems in web information retrieval based on semantic.The study and development of Guanzhong Region NMIP has been completed and put in running. The NMIP has 6 layers: sustainment layer, resource layer, tools layer, common services layer, application services layer and accessing layer. These layers functions as follows: Sustainment layer is for the base soft and hardware environment, resource layer for the inter-enterprise shared manufacturing resource, tools layers for the resource conformity tools, common services layer for the NMIP commonness services, application services layer for the connection of 3 application systems, including product innovation design system, open manufacturing system and resource optimization configuration service system, and accessing layer is for a SSO user page of the unification of authentication and authorization.The study and the achievements of this thesis shall play an active role to enhance the development of NM and enterprise information in China.更多还原
