MES system function module introduction
To win the market and win users, MES system must improve the quality, cost and other aspects. With the rapid development of information technology, the MES system provides a powerful tool for enterprises to improve their competitiveness. With today's manufacturing informationization construction, most manufacturing companies have gradually realized that the leading technology in production and the efficient management of manufacturing processes are the key to their own development.
Traditional manufacturing enterprises generally focus on information construction in two aspects: ERP management system and field automation system. However, relying solely on ERP and on-site automation is often unable to cope with the contradiction between production and management. ERP is mainly directed at the management of upper-level resources, can handle what happened before, and can also anticipate and deal with events that will happen, but it is now happening. However, the incident was not able to do anything. The traditional production site management was only regarded as a black box operation. The Manufacturing Execution System (MES) emphasizes the implementation of the manufacturing plan. It establishes a bridge between the planning management and the process control layer, which exactly fills the gap between the two.
MES is able to accurately schedule, send, track, monitor and control shop floor production information and processes, and at the same time it can measure and report its real-time performance. It is the basic technical means to achieve agility in the workshop.
The MES system has a total of 11 major functional modules including: detailed process scheduling, resource allocation and status management, production cell allocation, document management, product tracking and product list management, performance analysis, labor resource management, maintenance management, process management, and quality management. data collection.
The function of each module is briefly described as follows:
1. Detailed scheduling of operations: Optimize and sort job plans by sorting and scheduling limited resource capabilities;
2. Resource allocation and status management: Manage the resources required for production, coordinate the distribution of laborers, production equipment, tools, and materials to optimize them, and track their current working status and completion status;
3, the production unit allocation: through production orders to send materials or processing orders to a processing unit to start the process or step operation;
4. Document management: management and distribution of records and documents relating to products, process regulations, designs or work orders, and the preservation and maintenance of historical production data;
5, product tracking and product list management: by monitoring the workpiece at any time position and status information to obtain the history of each product, this record can be traced to the material components, or trace to the end of the product;
6. Performance Analysis: Provide the results report of the actual manufacturing process, and compare it with the historical records and the desired goals;
7. Labor Resource Management: Provides updated employee status information by minute (including working hours, participation rate, achievement confirmation, etc.) to facilitate the work of instructors;
8. Maintenance management: track the maintenance of equipment and tools, guide maintenance work, ensure the normal operation of machines and other asset equipment to achieve the factory's implementation goals;
9, process management: monitor the production process, guide the factory's workflow, improve processing efficiency and quality;
10, quality management: real-time analysis of information collected from the manufacturing site, tracking and analysis of the quality of the processing process to ensure product quality;
11. Data collection: Collect and organize data from the personnel, machines, and underlying control operations, as well as process material information, to obtain the required tables, records, or parameter data for internal production operations.
A company's manufacturing workshop is the intersection of logistics and information flow, and it is the economic center of the company. With the improvement of the market economy, the role of the workshop in the manufacturing enterprise gradually shifts from the traditional enterprise cost center to the profit center, which further strengthens the function of the workshop. Therefore, the manufacturing execution system MES, which is located in the workshop, has an important function. effect. It not only built a complete traceability system for the factory, but also improved the management level and enhanced the company's core competitiveness.
