Abstract
There is a lack of information flow from job shop environment to the CAPP (computer aided process planning) system, which prevents a CAPP system from being more practical. THCAPP-G (CAPP for garment, developed by Tsinghua University in 1994) is a two-stage, nonlinear, closed-loop and dynamic process planning system. It generates process plans taking advantage of the flexibility of the manufacturing process and job shop environment, according to the dynamic status of the job shop environment. Techniques of ES (expert system), CPA (critical path analysis), and heuristic method were utilized comprehensively. An information flow between job shop environment and CAPP system was realized in this system. The developed ideas and system structure are discussed mainly in this paper.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
