Abstract
A facility abnormality prediction model generation system includes: a data receiver receiving data of sensors of a facility previously obtained during an operation of the facility; an abnormality notification time predictor detecting a malfunction time of a malfunction of the facility based on the data of the sensors and determining an abnormality notification time for pre-notification of the malfunction of the facility based on the detected malfunction time; an optimal sensor combination calculator generating a chromosome based on the data of the sensors and performing a genetic algorithm using the generated chromosome to calculate an optimal sensor combination which is a combination of sensor data related to the determined abnormality notification time; and a facility abnormality prediction model generator generating a facility abnormality prediction model for the pre-notification of the malfunction of the facility, based on the optimal sensor combination.
