Abstract: An information processing device predicts, using a virtual plant which follows an actual plant, the occurrence of a first-type alarm in the actual plant in the case of implementation of each of a plurality of operation patterns virtually generated in relation to the operation of the actual plant by a worker. Then, the information processing device readjusts a prediction value, which serves as the basis for the prediction that the first-type alarm would be output, within a threshold value range; and performs re-prediction of the occurrence of a second-type alarm, which is different than the first-type alarm, using the virtual plant. Subsequently, based on the result of the re-prediction, the information processing device performs display control of the alarms predicted using the virtual plant.
