MES (Manufacturing Execution System) is a software system used in the manufacturing industry to monitor, control, and manage shop floor production processes. MES provides real-time information about production orders, work orders, inventory levels, equipment performance, and other relevant manufacturing data. It helps optimize operations, improve production efficiency, reduce errors, and ensure compliance with quality standards and regulatory requirements. Coupled with ERP to manage the five major categories of data: people, machines, materials, methods, and finances, and utilizing intelligent mobile devices in conjunction with IIOT (Industrial Internet of Things) systems, MES enables obtaining the most up-to-date production progress status on the production line, providing complete visibility into the current scheduling progress and actual production progress of the enterprise’s production line.
