Researches and applications on strange design and manufacturing cooperation systems on the concurrent engineering

This thesis is about the strange design and manufacturing cooperation systems. The ideas of concurrent engineering is applied in cooperation systems and the key problems involved the systems, the working conditions the rebuilding of developments, the forms, the working models, the issue of products data are analyzed and some corresponding solutions are worked out. Through the designs of approval of manufacturing products, the designs in different places of the products can be approved in order to keep the products data of different places in agreement. By the Fire Wall, the products data of the enterprise can be keep safely. Though exchanging the data and the information by the information platform, the virtual assembly, previewing and cooperation can be carried out so as to keep the developments of enterprise products in high speed and high efficiency.
