Production Control System(PCS) can be used in controlling productivity effectively. The system provides the workers and managers and with the management information. The objective of PCS is to improve and optimize productivity in practice. To achieve this goal, PCS must be applied in many Industries. Information System at Point Of Production(POP) is the system that helps worker and managers to analyze the various information at production line in practice. In this paper, we propose a new developed Client/Server POP System using "Bar Code." The new system can be integrated and communicated with CIM. The developed system can be used by engineers, managers, to improve productivity in practice. practice.
