Research on Engineering-Oriented Knowledge Technology.

Based on the analysis of engineering design process, a method of product structure modeling in design was presented. The knowledge processing technology for engineering design was researched: an engineering design knowledge can be represented with object-rule oriented method, which can better describe the tree-like product structure; using an integration of forward and backward reasoning can quick retrieve and solve the object variable; a rule using logic equation is developed to represent engineering design knowledge; a generalized table-based calculation language is developed to improve the integration between engineering theory and rule. Based on these technologies, a new knowledge system was developed which can be integrated into the design systems to improve their knowledge process ability. [ABSTRACT FROM AUTHOR]
