In the present invention, when an application system is controlled by utilizing various situation data and sensor information in an automated control system of various fields, control rules and information for controlling the system through analysis and classification of the current situation are required. In order to solve this problem, FCM clustering algorithm which is constructed to control application system by using existing FCM clustering technology and fuzzy decision tree technology using existing system control rules, newly generated control rules, and generated information We propose a situation recognition system using fuzzy decision trees.
