MES plays a central role in integrating automation. The development trends of modern factories are all oriented towards automated production methods, The last generation Manufacturing Execution System (MES) is limited to data collection and report analysis, which gradually hard to meet the needs of the rapidly changing era. The new generation of MES will be the core system of the whole plant automation control. It not only has the existing scope of MES, but also includes functions such as CIM, EAP, machine connection, integrated robot, conveyor belt, AGV, etc. To achieve the goal of automatic control of the whole plant, a large number of data analysis and prediction models are obtained in real time, in order to improve product quality and customer satisfaction, reduce production costs, and maximize the benefits of the enterprise.
