Recently, a lot of manufacturers are applying the manufacturing execution system (MES) to the automation system. The MES is not only linked to factory site, but also closely linked to enterprise management system. Standardization of MES is interested in the automation field and manufacturers. However, many IT companies provided MES systems to manufacturers. In this moment, it is difficult to make a standard for a MES structure and data by the international standard. Therefore, the ISO is developing a new standard of Key Performance Indicator (KPI) for MES in ISO/TC184/SC5.
