1 Overview
Manufacturing is an important pillar industry of my country’s national economy, and it occupies a central position in the secondary industry. With China’s entry into the WTO and economic globalization, China is becoming the center of the world’s manufacturing industry. China’s manufacturing enterprises are facing increasingly fierce domestic and international competition. How to quickly improve their core competitiveness is to use informatization to drive industrialization, accelerate the process of informatization, take a new road to industrialization, and achieve a leap in productivity in the entire society. Style development.
Looking at the application status of my country’s manufacturing information system, the focus of construction is generally on two aspects: ERP management system and on-site automation system (Shop Floor Control System, SFC). However, because product marketing has rapidly evolved from production-oriented to market-oriented and competition-oriented in the past two decades, it also poses challenges to the management and organization of the production site of manufacturing companies, and it is often impossible to handle it only by relying on ERP and field automation systems. This new situation.
The Manufacturing Execution System (MES) can fill this gap. The factory manufacturing execution system MES is a production management technology and real-time information system that has been rapidly developed internationally in the past 10 years and is oriented to the workshop level. MES can provide users with a fast-responsive, flexible, and refined manufacturing environment, helping companies reduce costs, deliver on time, improve product quality and improve service quality. It is suitable for different industries (home appliances, automobiles, semiconductors, communications, IT, medicine), and can provide good enterprise information management for single mass production and hybrid manufacturing enterprises that have both small batch production and mass production of multiple varieties. At present, the application of MES system by well-known foreign companies has become a common phenomenon, and many domestic companies have gradually begun to adopt this technology to enhance their core competitiveness.
