<p>PURPOSE: A production control system using an RFID(Radio-Frequency Identification) and a MES(Manufacturing Execution System) and a controlling method thereof are provided to improve the efficiency of a task by automatically giving useful information for process analysis to a manager using collected data. CONSTITUTION: A database(210) stores the state and positional information data about the direct factor of production according to the time unit among different data generating in the process. An application module(170) decides a current operating condition from the status and position information saved in the database. An application module calculates statistical values from status, position information and current operating condition data. A user interface unit(180) displays a simple graphical form so that an operator can easily recognize and deal the problem of a process. Position information data is collected by the RFID and the status information data is collected by the MES. The application module includes a status recognizing unit(230), an analyzing unit(240) and a reason finding unit(250).</p> |
