Production workshop without a complete set of information management system is difficult to develop in the market competition and even survive. If managers want to sustainable development and expansion of their own enterprises, they must work hard in the construction of information. Manufacturing Execution System (MES) has become the best choice of more and more entrepreneurs and enterprise executives. MES can make you better understand the development and "health status" of your own enterprise in the fierce competition at any time and anywhere.


Intelligent factory has developed rapidly in recent years. MES is a production management technology and real-time information system oriented to the workshop layer. It is the basic technical means to implement the enterprise intelligent manufacturing strategy and realize the workshop production agility. It lies in the middle part of the planning layer and the control layer of the enterprise -- the executive layer (namely the workshop layer). Although the enterprise has made great progress in the planning layer and the control layer in the operation, there are still unsolvable problems in the executive layer.


I. Current situation of workshop production


1. When consumers complain about the product due to quality problems, can we trace all the production process information of this batch of products according to the product number? Is it possible to immediately identify its raw material suppliers, operating positions/personnel, processes, and key process parameters?


2. Can timely count and monitor the quality information of each product in the workshop? Can automatically conduct statistics and analysis on product quality inspection data, distinguish random and abnormal fluctuations of product quality, and eliminate quality hazards in the bud?


3. When multiple types of products need to be mixed and assembled on the same production line, whether it can automatically check and operate the prompts to prevent workers from making mistakes in part assembly, product production process, product mixing and product handover?


4. What is the quantity of each product in the warehouse, in the pre-process, in the process and in the post-process line? Which sellers should we supply separately? When can we expect timely delivery?


5. How much time is the production line and processing equipment in production, and how much time is it idle and idle?


6. Can the manual report be abolished and the production quantity, qualified rate and defect code of each process be counted automatically? In the face of the above typical workshop management problems, the ERP system in the planning layer is difficult to provide a perfect solution, so the ERP system and the field automation system can not be connected. MES delivers information that enables the production process from the order to the finished product. MES system collects and ADAPTS timely and correct data while production activities are in progress, and provides appropriate guidance, response and report to decision support. The aim of immediate and quick response to changes in conditions is to reduce no added value activities and achieve more efficient production operations and processes. MES improves equipment recovery, on-time delivery, inventory turnover, contribution margin, and cash flow performance. MES provides the production information required for two-way communication between enterprises and suppliers.


Two. MES main characteristics


1. Suitable for diversified production processes, support multiple production lines, improve management efficiency, and effectively arrange production in multiple production lines for each batch of operations;


2. Establish a complete database, provide powerful query function, more complete and more in-depth information, can collect all the information on the production line at any time and anywhere, including the production line material and personnel capacity, maintenance, etc.;


3. Order-driven as the dominant production mode, quickly respond to the production of customized products;


4. Real-time and correct integration of online information facilitates decision making, and managers can obtain real-time information on the production line at any time;


5, Real-time monitoring of the production line, quality assurance tools;


6, data integration, analysis and statistics, easy to manage, the system can be for different equipment, different equipment state for statistical analysis, management personnel can have a target at any time for management, maintenance, daily maintenance, etc.;


7. Kanban visualization management is provided, which displays the work objective, completion status, defect rate, difference and other information of the current workstation, so that the manager can know the production and quality situation of the site in time and realize real-time transparent production and management.


MES system is the link of manufacturing process information integration. It Bridges the gap between enterprise planning layer and process control system in production workshop. MES helps enterprises implement complete closed-loop production by emphasizing the overall optimization of the manufacturing process, and also provides a good foundation for the construction of intelligent factories. Deep understanding of MES this advanced management thought, better use of MES in the workshop, will bring endless benefits for the enterprise.
