Approach of Knowledge Acquisition Based on Artificial Neural Network in Product Design Process

Establishing the relation between design process and product structure is an effective approach to realize knowledge acquisition in product design. In the paper, the method of artificial neural network (ANN) is applied by taking product structure as the point of knowledge acquisition, and ANN models are designed according to the design demands of different design stages, so that the relation between different design stages and the corresponding product structures could be established. Finally, the general design process of a roll plate machine is taken as the example and its BP network model is designed. The effectiveness of proposed approach is validated by training this network and forecasting the new design task.
