In recent years, with the rapid development of China's home appliance industry, competition is becoming increasingly fierce. In the face of brutal competition in the market, quality, cost, delivery, subject to the attention of the producers. More and more manufacturing companies start implementing MES (Manufacturing Execution System Factory Manufacturing Execution System), production scheduling, and optimization of production processes, to achieve effective communication with the upper enterprise resource planning and lower process control system in production workshop. Through the the MES system's construction, refrigeration in the United States to establish a real-time production management, quality management, logistics management, management and control model, which is more targeted to improve production performance, improve quality levels. By barcode in warehouse, workshop, production line flow, and data collection and refinement of production logistics, transparency and automation, quality control, real-time data of the integration of the material. Will eventually be finished and the key to the important parts, built from the supplier delivery, inspection, storage, production and picking, production process control, inspection, product storage, shipping, the whole process of the after-sales service barcode management. Can reach forward through the bar code of the automatic data acquisition of the manufacturing site, real-time production tracking, logistics tracking, quality control, but also by the follow-up to the service and other aspects of information feedback, reach forward to the reverse link retroactive to achieve monitoring of the production line, station personnel, quality, delivery, product development, customer services, multi-faceted, analysis, improvement. Firstly the needed technologies are introduced, from a technical point of view gives an overview of MES. Software engineering theory guiding ideology, the use of a software engineering methodology, described in detail the whole process of the implementation of MES system in Guangdong Midea Refrigeration Equipment Co., Ltd.. Business processes from the initial analysis of the MES system, covering the needs of research, design, implementation, has been to the production application, given a complete set of solutions targeted at the production site. And solutions at different levels, in different directions step-by-step description of the depth. Elaborated for the various stages of the problems encountered in the actual process of decision-making solutions. Study and explore the solution, there are still problems to discuss, given a viable proposition. Ultimately, the basic frame is extracted from the solution of the MES system, and the formation of a generic model to solve such problems.
