Research on object oriented information modeling in manufacturing planning for CAPP

Information modeling for tiered activities in CAPP is studied for the generation of manufacturing plan. Based on the systematic information modeling methodology, objects information activities and their relationship in manufacturing planning (MP) have been analyzed. The Object-oriented Systems Analysis (OSA) approach is used to describe the static and dynamic characteristics of information involved in MP. Therefore, the correlative relationships within the MP from part design to manufacturing plan can be properly described. A tri-level decision-making mechanism is employed to formulate the manufacturing planning model. So, the computer aided manufacturing planning (CAMP) under certain manufacturing resources has been realized. Finally, a case study of manufacturing planning is presented to verify the feasibility of the method
