MES is mainly for Discrete Manufacturing Enterprises (such as mechanical manufacturing, electronic appliances, aviation manufacturing, automobile manufacturing and other industries) and software systems in the process production industry (such as chemical, pharmaceutical, petrochemical, electric power, steel manufacturing, energy, cement, etc.
MES (abbreviated as manufacturing execution system) is an enterprise information system developed in recent years. It has been widely used in developed countries.
MES is a system between ERP (Enterprise Resource Planning System) and automatic control system (DCS, PLC, etc.). It is a bridge for the integration of management and control. For enterprises that have implemented ERP systems, A lack of MES system is equivalent to a "fault" formed between planning and process control ". MES is an enterprise information system connected to the production process. It is a key link for realizing comprehensive automation of enterprises.
The production execution system improves manufacturing competitiveness by controlling all plant resources, including materials, equipment, personnel, process instructions and facilities, and ensures optimal production behavior. The production information management system is mainly used to collect and transmit production data in real time and provide the designed functions (programs) to all managers who need it so that they can quickly understand the changes in production, we conduct targeted control over production to effectively control production. On the other hand, we analyze production data to find out the rules, improve production organization and management methods, and optimize the production management system.
The MES defined by the Association for Manufacturing Execution Systems has a total of 11 functional modules, but due to discrete manufacturing enterprises (such as machinery manufacturing, electronic appliances, aviation manufacturing, automobile manufacturing and other industries) there are major differences with the production modes, management modes, and automatic control levels of the process production industry (such as chemical, pharmaceutical, petrochemical, electric power, steel manufacturing, energy, and cement, therefore, there are large differences in MES systems in different industries, and the requirements of different enterprises in the same industry are also different. Therefore, it is not a single mes product that can be used all over the world, instead, we need to conduct targeted development based on the needs of different industries and enterprises. For chemical, metallurgical, and other process industries, various automatic control systems are networked to automatically collect data in the production process to integrate the production information of enterprises and establish real-time and historical databases throughout the plant, it is the most critical, core, and basic task for enterprises to implement mes applications.
MES is a production execution system solution for the production, logistics and other process industries on top of the real-time database system of DAS. Implementing MES can bring to enterprises:
(1) The upper-level managers of an enterprise can understand the operation status of the production site in a timely and intuitive manner;
(2) The control system and management system are organically combined to achieve data sharing;
(3) integrate multiple control systems for comprehensive analysis and unified planning of plant resources;
(4) The control system can perform deeper data mining and make full use of data resources.
MES includes the following upper-layer application modules for the process industry:
· Real-time information system
· Production Scheduling System
· Production cost accounting system
· Quality Management System
· Equipment Maintenance Management System
· Energy Management System
· Batch Management System
To win more profits and improve enterprises' core competitiveness, enterprises must start with production process management. Because manufacturing is the core of the factory, the factory manufacturing cost is the biggest source of the company's cost. The Production Department is the largest department in the factory, so it is of great significance to do a good job in production management and improve the level of production management. Today, competition between enterprises is over-competition in management, because enterprises understand that only by modern management means can they create better products and provide better products and services to customers, at the same time, enterprises can develop healthily and sustainably.
A production site that lacks production management means is like a "black box ". What happened at the production site? There is no complete information feedback. The production Execution System mes optimizes the management business of the manufacturing process through feedback results. The production process tracing function makes the enterprise very clear about the time when the raw materials of the product are provided, who the receiver is, and the inspection parameters, the time, technical parameters, operators, and other information of the product during the production process. Based on the feedback, the company can promptly adjust the reasons for high production cost or unstable product quality to provide better services to customers, in case of immediate customer complaints, we can also promptly and accurately clarify the problem for the customer and confirm the scope of impact. At the same time, the data in the product production process provides effective support for production management decision-making, so that problems in the production process can be exposed and handled in a timely manner, so as to effectively curb the occurrence of problems, eliminate product quality problems and abnormal production line conditions in the bud.
The production leader in charge of the factory needs to understand the production progress, task fulfillment, and product quality of the entire factory. Before using the production Execution System mes, the information can only be obtained through the report feedback or telephone report provided by the personnel. As a result, the enterprise management cannot issue management instructions in a timely and effective manner, which restricts the effective implementation of management measures. It is this "black box" of management that hides the eyes of management and binds their hands and feet.
Domestic manufacturing enterprises have introduced MES on-site execution systems to help enterprises break the "black box" and create visual factories to completely make the production process transparent. The production Execution System MES can monitor all the production processes from raw materials entering the factory to product warehouse receiving, and record the materials and equipment used by the products during the production process, data and results of product inspection, as well as the time and personnel of product production in each process. This information is collected and analyzed by the MES system. The system reports can be used to display the production progress, target fulfillment status, and product quality status at the production site in real time, and the utilization of production personnel, machines, and materials, so that the entire production site is completely transparent. The company's management personnel can clearly display the production site conditions, wherever they are, through the Internet. The boss at the Headquarters can also get information through mes to strategize customers who are far away from abroad, of course, can focus on their order progress and product quality.
What benefits does MES system bring to the factory:
1. Optimize the production and manufacturing management mode of enterprises, strengthen process management and control, and achieve the goal of refined management.
2. Strengthen the coordination of production departments to improve work efficiency and reduce production costs.
3. improve the timeliness and accuracy of statistical analysis of production data, avoid human interference, and promote enterprise management standardization.
4. provides effective and standardized management support for quality inspections of products, intermediate products, and raw materials of enterprises.
5. Real-time Control of information such as planning, scheduling, quality, process, and device operation, so that relevant departments can promptly discover and solve problems.
6. Finally, the MES system can be used to establish a standardized production management information platform to enable information interconnection between the on-site control layer and the management layer of the enterprise, so as to improve the core competitiveness of the enterprise.
