A Manufacturing Execution System (MES) is a system for managing and controlling the manufacturing processes in a production facility. With the emergence of Industry 4.0 and the interconnectedness of production facilities, formerly independent systems are consolidated into a central MES. This facilitates the digital representation, management, and supervision of all production processes within an intelligent, digitally-enabled factory. The data within this system is derived from various sources, including sensor-based systems and input provided by workers through digital interfaces on mobile devices or machine interfaces.
