Manufacturing Execution System (MES) (Manufacturing Execution System, MES) is the corporate bond CIMS information integration is the implementation of corporate strategy and achieving agile manufacturing workshop production of the basic techniques of agile methods. This paper introduces the concept of MES, functional model, and the MES and ERP and automation systems the relationship between the scene and describes the typical structure of MES systems.
manufacturing industry is an important pillar industry of national economy, in the secondary industry occupied a central position. With China's accession to WTO and economic globalization, China is becoming a world manufacturing center. China's manufacturing enterprises are facing increasingly fierce international competition, and how to quickly enhance their core competitiveness, it is important that the information to promote industrialization, speed up the process of informatization, walk new industrialization road, for full Social Productivity style development. Throughout our manufacturing information system application status, generally focus on the construction site on the ERP management system and automation systems (Shop Floor Control System,
la gear mens shoes, SFC) two aspects.
However,
la lights, due to product marketing in that,
la gear sale, two years from production-oriented and quickly evolved into a market-oriented, competition-oriented, and thus the field of manufacturing production management and organizational challenges, relying solely on ERP and on-site automation systems are often unable to cope with this new situation. Factories manufacturing execution system (Manufacturing Execution System, MES) just to fill this gap. Manufacturing Execution System MES plant is nearly 10 years, the rapid development of international-oriented shop floor production management technology and real-time information system.
MES can provide users with a rapid response, flexibility, fine manufacturing environment to help businesses reduce costs, delivery time,
la gears, improve product quality and improve service quality. Apply to different industries (home appliances, automobiles, semiconductors, communications, IT, medicine), can a single high-volume production and small batch production have both more varieties of hybrid mass production manufacturing enterprises to provide good corporate information management. MES-known in foreign countries, enterprise application systems have become commonplace, many domestic enterprises have gradually began to use the technology to enhance their core competitiveness. Back to business planning and process control layers of information between the layers of
simply to production from a planned level control layer: business market, according to the order or production plans, etc. - to reach the production site production plan - organization of production - product delivery. Information technology business management focus also mostly on the plan layer to production planning and management and general transaction processing. If ERP is the Production control in the lower layer, the enterprise mainly automated production equipment, automated test equipment, automated material handling storage equipment to solve specific production (process) of production bottlenecks, production automation and control site.
due to climate change and modern production management concepts constantly updated, a manufacturing enterprise can benign operation, the key is to of time to master the production site changes to make accurate judgments and rapid response measures to ensure production plans are reasonable and quick fixes. Although ERP and field automation systems have been developed to a very mature level, but due to ERP systems serving the top business management, general management process of the shop floor do not provide direct and detailed support. The main function of field automation system is on-site monitoring of equipment and process parameters, it can provide on-site inspection to the management and statistical data, but is not itself the true sense of the management system. Therefore, ERP systems and field automation systems of management information between the
example, face the following typical problems of the workshop, which is difficult to give satisfactory solutions means:
1, occurs when the consumer products complaints, whether written according to the products of these numbers back All product information on the production process? Can immediately identify it: the raw material suppliers, machine operation, the operator, through the process, production time and date and critical process parameters?
2, with a production line need to mix a variety of models, when assembled, can automatically check and prompt action to prevent workers from parts of the assembly error, the production process errors, product mix and product transfer error?
3, the last production line within 12 hours of the most frequent defects 5 What is it? Number is the number of defects?
4, the current warehouse and the former process, in the process, after the process number for each product line is the number? To which suppliers are to supply? When timely delivery?
5, production lines and processing equipment, the number of times in production,
la gear, and how much time idling in stopped? The potential impact of equipment is the main reason: equipment failure? Scheduling mistake? Not timely supply of materials? Worker training is not enough? Process indicators,
la gear shoes, or unreasonable?
6, whether the product quality testing and analysis of statistical data automatically, accurately distinguish the quality of the random fluctuations and abnormal fluctuations in the elimination of quality problems in the bud?
7, whether the abolition of manual reporting, automated production of statistics for each process, the number of pass rates and defects in the code? MES position, is at the planning level and field level implementation of automation systems, is mainly responsible for the implementation of shop floor management and scheduling. A well-designed MES system can be integrated in a unified platform, such as production scheduling, product tracking, quality control, equipment failure analysis, web reporting and other management functions, the use of a unified database and connection through the network simultaneously for the production department, quality inspection departments, technology sector, the logistics departments to provide shop management information services. System by emphasizing the overall optimization of the manufacturing process to help enterprises to implement a complete closed-loop production, to help enterprises to establish integrated and real-time of the ERP / MES / SFC information system.
