The Research Of Key Technologies Of Network-based Collaborative Design Center In Furniture Industry

Network-based collaborative design (NCD) is a new design pattern. During this process a design team devises a product concurrently and cooperatively, aiming at team work, and aided by a distributive collaborative environment provided by computer communication network. It's an epoch-making revolutionary to traditional design pattern, and it will radically shorten the time to market of a product, raise the design quality, reduce the design costs, improve the service completely and enhance the key competition ability of an enterprise. For this reason, NCD has become a hot spot of researcher and enterprise research.Sponsored by Heilongjiang province CAD application project "Furniture series of Products Computer Aided Design" and project "the Network-based Product Design Center of Furniture Manufacturing Industry" (No. 2001BA201A0605), which is a subproject of the Tenth-five National Key Project "Network-based Manufacturing Platform" (No. 2001BA201A06), this thesis made a systemic research on some key technologies of NCD, such as the network model, the collaborative design-supporting collaborative tools and the storage and query of product data and so on. With the furniture industry as the object of application, this thesis applied the research achievements to furniture enterprises, established the platform of the NCD in furniture manufacturing industry and settled the base of network-based design for furniture enterprises. This research has important theoretical significance and practical value.The major works of this dissertation are described as below:① By making a systemic analysis of the connotation, working pattern and its function requirement of a NCD, the researcher put forward the framework of collaborative design system, analyzed the key technologies need to be resolved of NCD, and presented these key technologies of this research.② The thesis does research on the integration about FCADS and NCD. In addition, it develops the interface between FCADS and NCD with ADO. From the both sides, FCADS and NCD can be realized the data sharing and integration. ③ Aiming at the data query of present distributive collaborative design environment, after having analyzed characters about data of furniture product, the author advanced a JSP-based on-line technique which can be used to query data, and verified it by experiments. The result indicates that JSP-based on-line technique is an economical, practical and quick method.④ By doing research on several main problems about collaborative session: control of collaborative session, concurrent control, collaborative awareness, aiming at collaborative problem of design center, put forward an effective way. ⑤ According to the requirement of Tenth-five National Key Project "the network-based product design center of furniture manufacturing industry", the author studied the methods to fulfill the collaborative design of furniture product, put forward a framework of the NCD platform for furniture product. Further the function of the NCD, the long-distance query are brought about.
