The document discusses a Manufacturing Execution System (MES). An MES connects, monitors, and controls manufacturing systems and data flow on the factory floor to improve production output. Its core functions include data collection, production scheduling, dispatching production units, production tracking, maintenance management, and quality management. An MES integrates with ERP systems and connects to programmable logic controllers to map production details to machine control parameters. Implementing an MES system can deliver significant benefits like reduced cycle times, work-in-progress, and quality issues as well as improved planning and customer service.
