The way for process decision of generative CAPP

The way for process decision of generative CAPP was studied in this paper, since process decision capacity determines the performance of CAPP system. Process decision problem was analyzed using hierarchical planning based on character and the basic generative CAPP process decision model was built. We use the production rules to describe the knowledge rules and propose a decision-making process by combining the knowledge rules reasoning with the case-based reasoning method. Thus, automation of the decision making process and both efficiency and quality of the process design are improved while the cycle of the process design is shorten simultaneously. This paper resolves some current problems existing in the development of CAPP system and may have a reference for the research and development of CAPP system.
