| With development of enterprise information technology, computer technology is applied very extensively in enterprise. In the field of engineering design the CAD(Computer Aided Design) take place of the traditional drawing manual. CAD develops along with the steps: throw away drawing board-integrate product information management-network system integration-CIMS. Increase of electronic data is doubled during the product life cycle. How to find information very exactly and fast and how to shorten the product life cycle and simplify redundancy is important problem for enterprise.EDM that makes document management for core treat with the data of product life cycle to ensure them same, safe and updated. EDM organizes data according to the relationship of product assemble. At the same time it provide chart for application easily exactly fast. A good design and successful execution EDM system will make information share more and increase transport speed and more safety. It also enhances ability for new production and makes business process more regular. Anyway EDM improve enterprise competitive power enormously.It is introduced a framework of collaborative product design workflow modeling and management. The system classifies the collaborative workflow integration related content(project management, market management, production design management, process management, supplier management standardization management). With EDM system each department can share related data and control project progress. Analyse the relationship of the CAD EDM ERP systems,at the same time, it Puts forward several integration models and analyse the capability of realizing; at last,combination manufacturing industry’ s status quo it has realized the Partial functions of integration of the three Systems. |
