Development history of MES management system

? MES is a new management mode and an advanced and effective management concept and method. This information management system (what is MES management system) integrates all resources within the enterprise, and plans procurement, production, cost, inventory, distribution, transportation, finance and human resources to achieve the best combination of resources and obtain the best benefits.

The advantage of MES management system is that it can help control business activities and promote communication between business units, such as: processing orders more efficiently and making production plans; Manage and analyze business processes in an interactive environment; According to the demand and production situation of production units, synchronize the activities of various departments; Monitor, * * * enjoy and track the information inside the enterprise, etc. The essence of MES management system is to strengthen the core competitiveness of enterprises, and its purpose is to comprehensively balance and optimize the management of resources (people, finance, materials, information, etc.). ) owned by enterprises, market-oriented, so that enterprises can give full play to their potential in the fierce market competition and obtain the greatest economic benefits. The formation of manufacturing execution system theory has roughly experienced the following stages:

? 1 MIS system stage (management information system) This information management system mainly records a large number of original data and supports query and summary.

? 2 MRP is an indispensable core function of MES. The function of basic MRP is to realize the integration of material information, ensure the timely supply of materials, reduce inventory and improve production efficiency. Closed-loop MRP is a "planning-execution-feedback-planning" closed-loop system, which adds capacity demand planning on the basis of basic MRP, so that the system has a balance between production planning and production capacity. MRP is a planning method to ensure that there is neither shortage nor backlog, which solves the contradiction between parts shortage and backlog that enterprises care about.

? 3 MRP (Manufacturing Resource Planning) MRPII is an information integration system developed on the basis of MRP to reflect the production plan and economic benefits of enterprises. The basic idea of MRPII is to take the enterprise as an organic whole, and from the perspective of overall optimization, use scientific methods to effectively plan, organize and control all kinds of manufacturing resources, production, supply, sales and finance of the enterprise, so as to make it develop harmoniously and give full play to its role. The core of MRPII is logistics, and the main line is planning. Along with the logistics process, there are both capital flow and information flow.

? 4 MES (Enterprise Resource Planning) MES is developed on the basis of MRPII. Based on information technology, it uses the advanced management ideas of modern enterprises to comprehensively integrate all the resource information of enterprises, and has become an all-round and systematic management decision-making platform tool for enterprise decision-making, planning, control and performance evaluation. MES management system breaks the old concept and mode that MRPII is limited to traditional manufacturing industry, and extends its reach to various industries, especially financial industry, communication industry, high-tech industry and retail industry. And greatly expands its application range.

? 5 MES management system in e-commerce era. The abundant competitive means and tools brought by e-commerce can help enterprises to make better use of MES management system to effectively combine the vast network business opportunities with the enterprise resource information in traditional information systems, so that customers or suppliers can realize information sharing and direct data exchange, strengthen the connection between enterprises, and enable decision makers and business departments to realize cross-enterprise joint operation.

? It can be seen that the application of MES management system can effectively promote the modernization and scientificity of existing enterprise management methods, adapt to the increasingly competitive market requirements, and is a shortcut to enhance the core competitiveness of enterprises.
