Abstract

An information processing device uses models generated under different conditions, and predicts alarms occurring in the case in which each of a plurality of operation patterns, which is virtually generated in relation to the operation of an actual plant by a worker, is implemented with respect to the actual plant. Then, the information processing device sets the degree of reliability of the prediction result regarding each of the plurality of operation patterns. Subsequently, based on the degree of reliability of the prediction result, the information processing device performs display control with respect to the alarms.

First claim

What is claimed is:

1 . An information processing device comprising:
a predicting unit that, using models generated under different conditions, predicts alarms occurring in case in which each of a plurality of operation patterns, which is virtually generated in relation to operation of an actual plant by a worker, is implemented with respect to the actual plant; a deciding unit that sets degree of reliability of prediction result regarding each of the plurality of operation patterns; and a display control unit that performs display control with respect to the alarms based on degree of reliability of the prediction result.

2 . The information processing device according to claim 1 , wherein, the deciding unit sets degree of reliability of the prediction result to be inversely proportional to difference between generation condition of the models and condition at time of prediction of the alarms.

3 . The information processing device according to claim 1 , wherein
in each of the plurality of operation patterns, load information is set that indicates load on the actual plant when concerned operation pattern is implemented, at time of performing prediction regarding each of the plurality of operation patterns, the predicting unit performs prediction using a model that, from among models generated using different sets of load information, corresponds to load information set for concerned operation pattern, and the deciding unit sets degree of reliability of the prediction result based on model used at time of performing prediction regarding each of the plurality of operation patterns.

4 . The information processing device according to claim 3 , wherein
the predicting unit performs interpolation or extrapolation using the models, and performs prediction corresponding to load information of each of the plurality of operation patterns, the deciding unit sets degree of reliability of the prediction result according to interpolation condition or extrapolation condition, and the display control unit performs display control of the alarms based on degree of reliability of the set prediction result.

5 . The information processing device according to claim 1 , wherein the display control unit
generates a display screen in which, regarding each of the plurality of operation patterns, sequence of occurrence of predicted alarms is displayed in chronological order, and suppresses, from among a plurality of alarms displayed in the display screen, display of alarms for which degree of reliability of the prediction result is smaller than a threshold value.

6 . An alarm prediction method comprising:
predicting, using models generated under different conditions, alarms occurring in case in which each of a plurality of operation patterns, which is virtually generated in relation to operation of an actual plant by a worker, is implemented with respect to the actual plant; setting degree of reliability of prediction result regarding each of the plurality of operation patterns; and performing display control with respect to the alarms based on degree of reliability of the prediction result.

7 . A computer-readable recording medium having stored therein an alarm prediction program that causes a computer to perform a process comprising:
predicting, using models generated under different conditions, alarms occurring in case in which each of a plurality of operation patterns, which is virtually generated in relation to operation of an actual plant by a worker, is implemented with respect to the actual plant; setting degree of reliability of prediction result regarding each of the plurality of operation patterns; and performing display control with respect to the alarms based on degree of reliability of the prediction result.
