Abstract
Economic globalization and the rapid development of information technology change the competitive environment, patterns of development and activity space of manufacturing deeply. In this context, product lifecycle management (PLM) came into being. PLM, managing all product-related data and processes, is the deepening and development of product data management (PDM). Small and medium-sized enterprises occupy an important position in national development and construction. Considering the problems in the process of current small and medium manufacturing enterprises, PDM technology and product life cycle modeling were studied in this paper. The architecture of PDM based on product lifecycle was established. A PDM system being suit for small and medium manufacturing enterprises was developed, which solves the management problem of product data in the whole lifecycle.
The main contents in this paper include:
(1) By studying the concept, architecture and main functions of PDM and product life cycle modeling technology and combining with the actual needs of an automobile company, the functional modules were designed, including user permissions management, drawings and documents management, product structure and configuration management, workflow management. The architecture based on product lifecycle in the C/S and B/S was built.
(2) Based on analyzing PDM system and other systematic information integrated model, the specific programs that PDM integrates CAD, CAPP and CAM systems were advanced. Focusing on the pivotal technology of PDM and CAD integration, encapsulation mode and interface mode were combined with each other to realize the double integration of PDM and CAD. Through using the SolidWorks API secondary development technology, a CAD plugin which integrates PDM functions was designed. An algorithm which can generate product structure tree automatically was studied.
(3) Based on Visual Studio.Net platform, by using C# programming language and choosing SQL Server 2000 as database, Object-oriented technology was applied to develop a PDM system based on product lifecycle. Users and permissions were connected by role. User permissions on resources were restricted by the permission of different users, which realizes the strict administration of people, data and process involved in different product lifecycle stages. Other pivotal technologies related to the system development, such as drawings and documents storage method and the addition and deletion of the nodes of product structure tree, were analyzed in detail to propose the particular solving scheme.

Keywords PLM; PDM; drawings and documents management; workflow management; information integration; product structure tree
