In recent years, with the proposal of new production modes such as JIT (just in time), BTO (order oriented production) and higher requirements for product quality from customers and the market, MES has been rediscovered and valued. Meanwhile, an invincible position of the network economy bubble has led enterprises to realize that they should enhance their competitiveness from the most basic production management. That is, only when data information is removed from product level (basic automation level), they pass through the operation control level and serve the management level, and the continuous information flow can be achieved to achieve enterprise information integration, so that enterprises can win an invincible position in the increasingly fierce competition. MES is rapidly and widely used abroad.

Manufacturing execution system (MES) aims to improve the execution ability of enterprises and has irreplaceable functions.
