Study on Distributed Knowledge Information System for Product Design

To overcome the limitations of commercial CAD andhandbook form of knowledge expression, the Distributed Knowledge InformationSystem (DKIS) for product design is proposed. The structure of DKIS andthe key issues in its implementation are introduced; the method ofknowledge store and transfer of DKIS is discussed. The mechanism ofknowledge representation, acquisition and utilization, based onInternet network, is achieved. Based on the concept of functiondriven, integrated Artificial Neural Networks and Active Server Pagestechniques, transplanting the trained ANN into DKIS system, a new method forretrieving knowledge in DKIS over Internet is achieved. Finally, aprototype of DKIS is developed to demonstrate the feasibility of thestructure and constructional method of DKIS. The work provides a schemefor speed knowledge acquisition and shortens the cycle of productdevelopment.
