Application of MES system in Industrial Enterprises

Manufacturing Execution System (MES) is a software system that combines the human, material, mechanical equipment, raw materials, and other factors of the factory to ensure the quality, quantity, and delivery time of production products, this system is based on enterprise ERP and PCs systems. It comprehensively targets production management technologies and real-time information systems, and mainly implements manufacturing plans, it also provides a bridge between the planning management layer and the production control layer to connect the two.

  1. Significance of MES system for production and operation of Industrial EnterprisesAn efficient production-centered information management platform built by the MES system, which notifies all data on a unified platform, so that staff can understand the production information of the enterprise at the first time, it can understand the actual business status of production operation in real time and better understand the production cycle of each stage of production operation. In the production process of industrial enterprises, the production data, quality and measurement data are fully integrated, and data sharing is achieved for each business that is conducive to production, it can provide more comprehensive management measures for problems existing in the production process, improve production efficiency and stability through supervision and control in production, and reduce production costs, this is the essential condition for enterprises to maximize economic benefits. The MES system not only achieves visualization and real-time effect in the enterprise production process, but also makes the production monitoring process more transparent, it ensures the Standardized Management in the production process and strictly checks the accuracy of the production information of the production products in the production process, which also becomes the most reliable basis in the production management, the MES system can improve the economic efficiency and competitiveness of enterprises in the production and promotion of enterprises, which is of great significance to the development of enterprises. 2. Architecture and functions of Industrial Enterprise MES systemThe purpose of intelligent and Information Design in factory design is to build a computer integration platform with good scalability, security, and efficiency, so that the application systems of information technology can run efficiently on this platform, use advanced information technology to reduce operating costs and improve office efficiency and personnel and equipment security. Enterprises are gradually built into a first-class network, information, intelligent, and digital factory in the industry. Industrial enterprises generally manage the entire information management system from both horizontal and vertical aspects. Horizontally, it includes all aspects of project management for production, supply, sales, finance, personnel, and other equipment maintenance, the vertical structure is from the bottom-layer production equipment to the production line and Material Supply Control System. A complete industrial information system is divided into five layers: Level I system-equipment control system; Level II system-process control system; Level III system: MES system; level IV system-ERP system; Level V system-inter-enterprise management system and decision support system. The system architecture diagram is as follows: Information System Structure System diagramIt can be seen that the basic automation system and process control system of level 1 and level 2 are mainly used for the operation control layer, while the MES Manufacturing Execution System of Level 3 is to manage the operations in the factory workshop, the level-4 enterprise resource planning system is the most critical for enterprise management. It needs to implement management based on market demands and the overall production capacity and management plan of the enterprise. Finally, level 5 systems are the management of enterprises. They are the extension of information management on the basis of Level 4 systems. They can closely connect the supply and sales of enterprises, in this way, the efficiency of the entire supply chain is improved to realize real collaborative e-commerce, including the Supplier Relationship Management System (SRM), Supply Chain Management System (SCM), and product lifecycle management system (PLM) product Project Management System (PM), infrastructure Geographic Information System (GIS), Integrated Office Management System (OA), decision support system (DDS), and Enterprise Portal System (portal. According to a series of planned production and optimal scheduling arrangements, the actual information of production equipment and even the whole production process must be fed back to the Enterprise resource plan, in this way, information exchange and real-time communication at all levels are more closely formed. 3. Conclusion 

MES is an important part of enterprise informatization construction. It is closely linked to various departments of Industrial Enterprises. It enables timely reporting of large amounts of data and handling and response to problems, to optimize the management in the production process. On the one hand, the management system on the previous layer provides data feedback, and the management system on the next layer continues to produce commands. Both devices and enterprises can be well controlled to achieve data connection and sharing, achieve integrated product quality, integrated logistics services, and integrated production control, this forms an enterprise information system with MES as the core.
