The structure and implementation of a distributed integrated information system for product design

To overcome the limitations of commercial CAD and the handbook form of knowledge, a distributed integrated information system (DIIS) for product design is proposed. The structure of DIIS and the key issues of its implementation are introduced; and the method of storing and transferring data in DIIS is discussed. The mechanism on knowledge represented, stored and acquired quickly in DIIS, which is based on the Internet, was achieved. Based on the concepts of function driven knowledge, connected artificial neural networks and active server pages, the trained ANN was migrated into the DIIS system, a new method for retrieving knowledge in DIIS on the Internet is achieved. At last, a prototype of DIIS is proposed to demonstrate the feasibility of the structure and constructional method. This paper provides a scheme for acquiring knowledge quickly and shortening the cycle of product development.
