Research On Product Data Management In Product Research & Development Process

With the increasingly fierce competition in modern market, enterprises are facing increasing pressure. How can manufacture products of higher quality and lower cost in a shorter time, which is the key of improving production efficiency. Today, most enterprises have taken the application to production design just as CAD/CAM/CAPP and other computer-aided technologies CAX. The using of these technologies has greatly enhanced the efficiency of production development, but also taken many problems. Because different departments use different CAX systems, which is lack of complementarity between the information of a large number of product data. Information which can not be effectively shared results in the formation of some "information islands", and a lot of useful data information can not be classified and managed in time and effectively, and it will affect the efficiency of product development. Product data management(PDM)system is aimed at integrating and managing the enterprise's product data information effectively, and solving the problems above.The main work of this dissertation is: Expatiate on the product data management's research background and project source, purpose, the development trend and the developing situation of China. Analyse some key technologies of the development and application of product data management, and ensure the specific areas of PDM system clearly. Aiming at products'characteristics of Anhui Taier Heavy Industry Co. Ltd., ensure the PDM target, and make a needs analysis to flexible code, product objects, users and so on. With a specific example of designing development of product data management, illustrate the functions and relations among all major PDM system modules, including product management module, right management, system management, collaborative management and workflow management and so on.System is simple and practical, but also takes the product data's flexibility and expansibility into account fully. And it can improve production efficiency. Finally , sum up the total essay and point out the shortcomings of the essay and works to further improve and the direction of future efforts.
