Research On 3D Networked Collaborative Design Based On MAS

Networked manufacturing is becoming an advanced product manufacturing mode, with the development of economic globalization and significant revolution of production pattern and management method, and is becoming a leading technology for manufacturing industry. The corresponding technologies of networked manufacturing more and more become the focus in the domain of manufacturing research and implementation.Networked collaborative design is one important technology in the field of networked manufacturing, and a new design pattern with technical development of computer and network. It is defined as that designers collaborate with any other member of a workgroup to finish one design task in network supported by computer. Networked collaborative design is a technical advancement with an epoch-making significance to the traditional CAD technology and its design pattern. It would become one of the key technology in enterprises for reason that the product development period would be radically shorten, the design costs would be reduced and the competitive power would be enhanced through technically implementing the networked collaborative design.In this dissertation, the systemic research on architecture model of the 3D networked collaborative design based on MAS and the key technologies of the system platform realization supported "multi-client & multi-task" project management were made, and this is combined with Liaoning province momentous scientific & technical project "Research on constructive strategy on networked manufacturing and platform supported networked manufacturing" (No.20032200025) and Liaoning province scientific & technical fund project "Research on collaborative design about mechanical equipment based on CSCW remote control"(No.105057).The collaborative design archetypal platform for manufacturing enterprises was developed and established according to corresponding research, which is the technical foundation for implementing the networked collaborative design technology in the manufacturing enterprises.The major works of this dissertation are described as follows:(1) The conception, characteristic and important content of networked manufacturing are investigated and summarized. Consequently, the development and the researching contents of computer supported collaborative design (CSCD)are confirmed by analyzing the CSCD's definition, status and significance in domain of networked manufacturing. (2) The operation patterns of the CSCD are systemically analysis, as well as Multi-Agent system. The functional and the architectural models are established, which is supported the mechanism of oriented project-management and supported "multi-client & multi-task". Subsequently, the general Agent model of 3D CSCD system architecture based on MAS is constructed. These are the theoretical foundation and implementing framework of the whole thesis.(3) The 3D collaborative design mechanism of oriented project-management and supported "multi-client & multi-task" is put forward. And according to the workflow of the 3D CSCD based on MAS, the algorithm of Fuzzy Analytic Hierarchy Process (F-AHP) is employed in choosing partners, and the method of Design Structure Matrix (DSM) is applied in process of decomposing and assigning design tasks. These fulfill matrix project management mechanism of collaborative design.(4) The key techniques of 3D networked collaborative design system based on MAS were researched. The database creation based on SQL Server and its accessing mechanism based on OLE DB were applied in system data services technique, the data communication technique based on XML Web Services and developing client application based on COM technology were employed in the key techniques fulfillment.(5) In the base of theoretical foundation and key techniques fulfillment, the archetypal system platform of the 3D networked collaborative design based on MAS was built according to the corresponding projects'demand. The platform operating performance was test aiming at practice mechanical product collaborative design for certain manufacturing enterprise.
