Research On Product Data Management And Its Correlation Technologies Of Manufacturing Enterprise

More and more digital information has been input into the computer system of manufacturing enterprise, the product data has been the most important inventory on which the enterprise's daily operation depend. Meanwhile, it has been very difficult for people to find the correct information from such enormous data pool. Most enterprises are making efforts to find a way to improve their product design efficiency; to reduce time to market and lower manufacturing costs. It is required that designer should consider assembly, manufacturing on the very early stage of product development. It is so-called "Concurrent Engineering". Product data management (PDM) is considered to be the ideal platform to implement concurrent engineering. It is also a power tool in integrating enterprise's various IT systems.The paper firstly discusses the concept and content of manufacturing informatization in detail, and then focus on the methodology and tools of PDM to expatiates its status and character in manufacturing informatization., including the naissance and development , the basic concept and function, the system architecture and the key IT technology of system building , the implementation and deployment of PDM systems, etc.As a large scale software system, PDM related to many IT technology, and it must be developed under software engineering technology. The most important character of PDM is: open and integration. So there is something special for choosing the software platform and develop tools of PDM system. The paper discusses and researches the key technology of PDM's development, such as: Object-Oriented Technology, DBMS application, software develop technology, etc. Then it gives the static objects architecture tree of PDM, and discusses the mechanism of electronic data vault in detail, the technology and methodology of software develop also was proposed.PDM is not only a software system, but also a management task. So the implementation and deployment of PDM is a system engineering, it needs the effort of whole people of enterprise, especially the effort of manager and IT technician. The paper give the general procedure of PDM implementation and deployment, such as software choosing, system information model design, main content and step of deployment, system evaluation, etc. Then, the paper analysis the situation and problem of our country's PDM application, some useful advice also has been given.Finally, the paper applies the theory and technology discussed above to build an actual system: 716PDMs, which was developed for 716 academe of China boat industry.
