Research on Rough Theory-based Knowledge Push in Product Collaborative Design
摘要
Abstract
Aiming at the difficulties in searching knowledge, a knowledge matching technology based on rough theory in product collaborative design was proposed. Firstly, the architecture of product collaborative design knowledge match was constructed, and the knowledge match flow was analyzed. Secondly,rough sets theory was used to calculate the importance of the functional,and the sequence of matching knowledge was determined. Thirdly, the knowledge with product restrained condition was matched and pushed through text similarity computation. Finally, this method was applied to an engineering case. The results of application prove the feasibility and availability of this method.关键词
