MES system and ERP system comparison and implementation

In MES system, through the integration of ERP planning information, real-time energy consumption and planning data can be intuitively compared, which can effectively control or avoid repeated cross operations between managers of different systems, so as to improve work efficiency. The management system of the factory itself of the manufacturing enterprise is far from perfect. In addition, internal personnel mobility is relatively large. Once the staff is lost, the system he sets up will change with the arrival of the new head. That's not the case. It is convenient to use MES system to sort out the business process in the project definition stage; The change of market environment and the continuous renewal of modern production management concept have led to the transformation of enterprise production mode, and the managers of enterprises and workshops have found the importance of workshop. The key to the healthy operation of manufacturing enterprises is the close cooperation between "planning" and "production".

Enterprises and workshop managers can master the changes on the production site in a short period of time, make accurate judgment and rapid response measures, to ensure that the production plan is reasonable and rapid modification. Although ERP and field automation systems have developed to a very mature level, because ERP systems serve the upper layer of enterprise management, it generally does not provide direct and detailed support for the shop-floor management process. The function of field automation system mainly lies in the monitoring of field equipment and process parameters. It can provide managers with on-site inspections and statistics, but it is not a real management system in itself. Therefore, there is a "fault" in the management information between the ERP system and the field automation system. They are often helpless or weak in terms of scheduling and management requirements at the workshop level of users.

The promotion of MES system should guide all employees to set up correct work goals, give full authorization and provide strong resource support. Reduce supply chain cost, enhance quick response to customer demand, optimize customer service, improve the overall work efficiency of the company. The real-time database is connected with the field control equipment, which is the bridge connecting the production process control system and THE ERP to form MES support platform, so that enterprise managers can obtain the real-time data of the production process in time, realize the integration of management and control, and make the management information system run in real-time and efficiently. For example, the response of the field control system to various information data is in seconds, the response efficiency of MES is in minutes, and the upper planning system is in days or even weeks. MES system just developed in China, lack of actual combat experience. Many enterprises have a vision of MES system, but there is no correct understanding of the concept, the implementation of the determination is not strong. In contrast to a total solution containing all possible functions, AN MES system must be composed of a series of modules so that the factory can choose the appropriate modules to implement according to its own business situation.

MES can integrate production scheduling, product tracking, quality control, equipment failure analysis, network reporting and other management functions on a unified platform. The production department, quality control department, process department, and logistics department use a unified database, which can be used simultaneously through network connection. Department to provide workshop management information services. The production process of process industry is basically continuous, so it is very important to accurately grasp the actual production situation in the whole production process. Only by accurately tracking the production parameters and operation of each equipment can we ensure the effective implementation of the production plan.
