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.
Claims8
An information processing device comprising:
- a generating unit that generates a first model under a first condition and a second model under a second condition different from the first condition;
- a predicting unit that predicts an occurrence of at least one alarm by performing a simulation for an operation pattern, which is virtually generated in relation to operation of an actual plant by a worker under a third condition different from the first and second conditions, by interpolating or extrapolating the first model and the second model;
- a deciding unit that sets degree of reliability of prediction result regarding the operation pattern based on a difference between the third condition and the first and second conditions;
- and
- a display control unit that performs display control with respect to the occurrence of at least one alarm based on degree of reliability of the prediction result.
An alarm prediction method comprising:
- generating a first model under a first condition and a second model under a second condition different from the first condition;
- predicting an occurrence of at least one alarm by performing a simulation for an operation pattern, which is virtually generated in relation to operation of an actual plant by a worker under a third condition different from the first and second conditions, by interpolating or extrapolating the first model and the second model;
- setting degree of reliability of prediction result regarding the operation pattern based on a difference between the third condition and the first and second conditions;
- and
- performing display control with respect to the occurrence of at least one alarm based on degree of reliability of the prediction result.
A non-transitory computer-readable recording medium having stored therein an alarm prediction program that causes a computer to perform a process comprising:
- generating a first model under a first condition and a second model under a second condition different from the first condition;
- predicting an occurrence of at least one alarm by performing a simulation for an operation pattern, which is virtually generated in relation to operation of an actual plant by a worker under a third condition different from the first and second conditions, by interpolating or extrapolating the first model and the second model;
- setting degree of reliability of prediction result regarding the operation pattern based on a difference between the third condition and the first and second conditions;
- and
- performing display control with respect to the occurrence of at least one alarm based on degree of reliability of the prediction result.
