Design And Implementation Of General Group's Product Development Management System

General Group Product Development Management System is an enterprise product data management system. It combines product configuration, document management, work procession management and project management into one united body. Together with the product development subsystem in management information system, it forms an integral automatic system of product development and manufacturing process. The main object of it is to digitize product formulation, integrate and share product data, monitor procedure from product design to manufacture in real-time, optimize work process, improve develop efficiency and back up enterprise participate in market competition effectively.In this paper, the concept and meant of general group PDM system are introduced briefly. It also involves technique and industry background. The techniques at home and abroad and the application situation are summed up. The main problems should be solved by PDM system are clarified. The demand of PDM system function and data integration raised by general group is analyzed in the paper. Six functional modules are designed based on enterprise standard and work flow, including formulation management, raw material and accessories management, product visualization design, document management, development information management and work flow management.In the description of system implementation, how to use Teamcenter as a product solution plan to construct a platform supporting synergetic development research is introduced. Five layers system framework based on implement characters is prefer to, including supporting layer, maintaining layer, function layer, customization layer and interface layer. It makes business go beyond areas, departments and technique boundaries by using entirely opening and standard web techniques. It supports internet and web techniques and can provide complete product lifecycle managementThe PDM system uses object oriented techniques. It is provided to customize or exploit functions like expanding class, expanding attribute, define method, define interface and define dialog box. Graphic tools like Rational Rose are also provided to make program which lower implement cost and facilitate system function expansion.PDM system is based on J2EE substructure, it provides object oriented and enterprise graded management framework, which is system integrated and structuralized, supporting distributed transaction management. The system uses extensive makeup language (XML) as development circumstance language so as to make sufficient prepare for system upgrade, guarantee the system can exchange data and integrate applications across platform or district. To make the best use of the valuable extant resource and personal innovation in enterprise, the system divides data space into several areas including personal area, cooperation area, checking area, project data area, model data area and shareable data area. The system modeling is object oriented, it provides through ways for management of object, object relation, object function and object interface. It not only ensure the management scope can change with needs, but also solve the difficult problem of contradiction between personal need and system upgrade. The standard distributed browser based on JAVA makes data be accessed only at server node, and it leaves nothing at client node.The system investigation, development and running conditions are also involved in the paper.
