The Manufacturing Execution System (MES) provided by MONARCH adopts a distributed computer information system, which is composed of one or multiple levels of monitoring centers. The system is mainly composed of three parts: the production monitoring center, the production information network, and the on-site monitoring units. Taking the production process monitoring and production performance assessment as the core, the Manufacturing Execution System (MES) relies on the production process quality control, production equipment management, and energy management as support, and seamlessly integrates with control systems and other information systems. It realizes the visualized and refined management of the production process, thereby improving production efficiency, ensuring production quality, and reducing production costs. The functions provided by the system include production process monitoring, production operation management, production inventory management, energy management, equipment management, quality management, safety and environmental protection management, system management, etc.
