Distributed decision-making modeling for computer aided process planning

Decision-making in process planning is always the pinch point of CAPP system.. A novel decision-making model for CAPP is presented in the paper. In this model, the approach based on both. operations and features, instead of the. conventional based on only feathers, is employed to make. results of decision-making become more practical. The manufacturing resources and environments are also mapped into a dynamic model to help decision-making work more flexibly. Then, the distributed process planning system is formed with many independent sub-systems that follow the method of expert system. The cooperation of all sub-systems makes the function of CAPP more flexible and powerful.
