The application of MES computer in manufacturing industry and the development of computer itself are closely related to the evolution of production mode. In the past, the production mode was relatively simple and belonged to the top-down planning mode. Computer application focuses on production planning management (MRP-II) and general transaction processing, while field operation management still stays in the traditional manual window operation mode. Even if there is so-called workshop floor control-SFC, it is limited by traditional large/micro computers and electronic technology. Most of them are input in batches after collecting relevant data, and the functions provided are limited. In the aspect of factory automation, logistics automation was mainly emphasized in the past, such as automatic production equipment, automatic test instruments, automatic logistics processing and storage equipment. They did replace a lot of manpower and solve some production bottlenecks, but they did not play their due role because of improper cooperation of related operations, so they were called "automation islands". In order to solve the above problems, we need a front-line data automation system. If this system is used in the factory manufacturing site, we call it Manufacturing Execution System (MES). In Japan, they call it production point POP, which can simulate the point-of-sale POS in commercial automation. The name Japan is still relatively vivid, because the spirit of POP and POS is the same, and the concept is the same. It can be said that it is a bottom-up information management system, which can grasp the on-site situation in real time. Before MES was introduced, the company's MRP system communicated with the production site manually, which made the production site like a black-box operation, unable to grasp real-time and correct information. After the introduction of MES, it not only provided the automation of field information flow, but also played a connecting role, reaching the realm of computer integrated manufacturing-CIM. It is not difficult to see the interactive relationship between MRP (Manufacturing Resource Planning) or ERP (Enterprise Resource Planning) systems from three English abbreviations MES, one is the upper planning system, and the other is the lower actual execution system. Manufacturing Execution System (MES) can just fill this gap. MES, the factory manufacturing execution system, is a production management technology and real-time information system that has developed rapidly in the world in recent 10 years. MES can provide users with a quick response, flexible and fine manufacturing environment, and help enterprises reduce costs, deliver goods on time, improve product quality and improve service quality. IT is suitable for different industries (household appliances, automobiles, semiconductors, communications, IT, medicine), and can provide good enterprise information management for single mass production and mixed manufacturing enterprises with both small and large-scale production of multiple varieties. At present, the application of MES system by well-known foreign enterprises has become a common phenomenon, and many domestic enterprises have gradually begun to adopt this technology to enhance their core competitiveness. Back to the information "fault" between enterprise planning layer and process control layer, the traditional production process adopted by China manufacturing industry for many years is characterized by "top-down" production as planned. Simply put, it is from the planning level to the production control level: enterprises make production plans according to orders or markets, and the production plans arrive at the production site, organize production and deliver products. The focus of enterprise management informatization construction is also mostly at the planning level, with production planning management and general affairs handling. For example, ERP is located in the upper planning layer of an enterprise, which is used to integrate the existing production resources of the enterprise and prepare the production plan. In the lower production control layer, enterprises mainly use automatic production equipment, automatic testing instruments, automatic logistics handling and storage equipment to solve the production bottleneck of specific production (process) and realize automatic control of production site. Due to the change of market environment and the continuous updating of modern production management concepts, the key to the benign operation of manufacturing enterprises is to make the "plan" and "production" closely cooperate, so that enterprises and workshop managers can grasp the changes in the production site in the shortest time, make accurate judgments and take quick countermeasures to ensure that the production plan is revised reasonably and quickly. Although ERP and field automation system have developed to a very mature level, because the service object of ERP system is the upper level of enterprise management, it generally does not provide direct and detailed support for workshop-level management process. The function of field automation system is mainly to monitor the field equipment and process parameters, which can provide field detection and statistical data for managers, but it is not a real management system. Therefore, there is a "fault" in management information between ERP system and field automation system, and they often appear powerless or weak in function for the scheduling and management needs of users at the workshop level. For example, faced with the following typical problems of workshop management, it is difficult for them to give a perfect solution: 1. When a user complains, can you trace all the production process information of this batch of products according to the product number? Can you immediately find out its raw material supplier, operating machine, operator, process, production date and key process parameters? 2. When multiple models of products need to be mixed and assembled on the same production line, can you automatically check the operation tips to prevent workers from assembly errors, product production process errors, product mixing errors and goods handover errors? 3. What are the five most common product defects on the production line in the past 12 hours? What is the number of defective products? 4. What is the quantity of each product in the warehouse and the pre-treatment, intermediate treatment and post-treatment lines? Which suppliers do you want to supply separately? When can you deliver the goods in time? 5. How much time is the production line and processing equipment in production, and how much time is it stopped and idling? The main reasons that affect the production potential of equipment are: equipment failure? Scheduling error? Material supply is not timely? Inadequate training of workers? Or is the process index unreasonable? 6. Can the quality inspection data of products be automatically counted and analyzed, and the random fluctuation and abnormal fluctuation of product quality can be accurately distinguished, so as to nip the quality hidden trouble in the bud? 7. Can you cancel the manual report and automatically count the production quantity, qualified rate and defect code of each process? The positioning of MES is the executive layer between the planning layer and the field automation system, which is mainly responsible for workshop production management and scheduling execution. A well-designed MES system can integrate production scheduling, product tracking, quality control, equipment failure analysis, network reporting and other management functions. On a unified platform, using a unified database and connecting through the network, it can provide workshop management information services for production departments, quality inspection departments, technical departments and logistics departments at the same time. By emphasizing the overall optimization of manufacturing process, the system helps enterprises to implement complete closed-loop production and establish an integrated and real-time ERP/MES/SFC information system.
