Minor enterprises are very important in our country. Manufacturing is highly developing. Product Date Management (PDM) is comparatively successful in large factory. However, on the one side, the features of Minor enterprises have restricted its PDM development. On the other side, PDM software is very success in the foreign countries. But our PDM lakes special features besides prices advantage. So we should develop our PDM which fit the Minor enterprises'requirement and own its advantages to occupy the PDM market.The product design is this PDM system's core. Throw analyzing the minor enterprises'features, we can improve the working system and flows and the management in currently machine conditions. The aim is to solve the enterprise's problems and to develop its design ability. So the enterprises can produce low cost, highly quality and requirable products in a short time.This passage build software framework of the PDM firstly. Then propose the parametric design and reconstruction about the function flow. |
