A TRANSACTION MODEL FOR INTELLIGENT CAPP SYSTEMS

Probability and uncertainty of process plans are important issues for intelligent CAPP systems. The model described in the paper can balance the scale and efficiency of intelligent planners, and build a man machine cooperation environment. Procedure termination, planning navigation, task generation ＆ reorganization, data dispatch, and planning state interpretation make up the internal transactions of a CAPP system. Their combination is characterized by varied forms, such as recursion, loop, sequence, concurrence, and backtracking.The knowledge about feature, part, process resource,and enterprise is used to plan a manufacturing process. The model improves the system’s reliability and operation efficiency, and its key technique is implemented in a GS CAPP system.
