Integration of the CAD/PDM/ERP System Based on Collaborative Design

The increasing requirement and product complexity need a new design method for the global market. The collaborative design is an important style for the requirement. The CAD system for design is connected with the Product data management (PDM) and enterprise resource planning (ERP) system for management. PDM can support the management of engineering data and the product development. A methodology for the PDM/ERP/CAD integration is proposed. Firstly, the interest of integration of PDM/ERP/CAD is introduced. Then the UML-based methodology is applied for the product data integration model. The PDM structure model diagram and the class model diagram are introduced. Workflow method for the method is introduced. By workflow method, the data publican is realized by the trigger. The data among systems can be visited and exchanged by the methodology. As a result, the design and management models are modified, simultaneously and maintained consistently. The methodology is applied for a system by means of an example, which achieves a good result.
