Research On Collaborative Design Management System Oriented To Networked Manufacture

The increasing market competing make the networked manufacture emerge. The enterprises must occupy the market by decreasing cost, improving product quality and shorten the product developing time in the fiercely competitive market. Networked manufacture is a new manufacture style in the circumstance, which establishes the dynamic alliance to realize the networked manufacture with the computer technology and network technology.Product development is one of the importment factors in the process of enterprise manufacture, which determine the development of enterprise.Collaborative design is an important part of the networked manufacture, which can shorten the developing time, decrease the enterprise’s cost, and improve the product quality.The paper is supported by related foundation project to study the collaborative design in network circumstance. It combines with the heavy duty enterprise to study the system structure, design process schedule, the design model interoperated and the knowledge management in the process of collaborative design. The work is the following:(1) In view to complexity of the collaborative task, the task scheduling is studied. The Design Structure Matrix is applied to decompose the collaborative task. The disserve algorithms is applied to decouple the couple task. The fuzzy AHP method is applied to determine the weight of the task to allocate the task. At last, the collaborative design task is scheduled reasonably.(2) The interoperated method for model is studied. In view to three dimension model, the feature model is studied; the increment model is studied for the system. The exchange model style and the coordinate are also studied. The increasing transmission method is realized. The history feature model is re-established and recognized. At last, the method is applied with the Pro/E and UG(3) Conflict resolution problem in the collaborative design is studied. The conflict reason and the resolution problem are studied. The constraint method is applied on the detecting the confict.A CBR method is studied for the conflict resolution. The designer’s right is restricted.(4) In view to the requirement of knowledge resuse, the knowledge management of collaborative design system is studied. The knowledge representation is studied, which is by OWL. The knowledge discovery, knowledge reuse and the knowledge sharing is studied. The design history is recorded with a model. The PLM design and integration is studied in the paper.(5) The paper studies the process of the collaborative design in the networked manufacture and establishes the process of design of some enterprise. The system structure is the hybrid one with B/S and the C/S, and is on the multi-agent system structure. The system model is established by the colored Petri nets for collaborative design process.(6) In view to the shielding machine of some enterprise, JSP, Java and SQL Server is applied to develop an archetypal system named NCDS. The function of system is realized, which is right.
