When a worker executes an operation on an actual plant, an information processing device generates a first calculation result obtained by calculating a behavior of the actual plant after execution of the operation using a virtual plant following an operational status of the actual plant and generates each second calculation result obtained by calculating a behavior of the actual plant with respect to each of operation pattern plans corresponding to a state of the actual plant. The information processing device evaluates the operation that is executed by the worker based on the first calculation result and the second calculation result.

Information processing device, evaluation method, and computer-readable recording medium

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.

Information processing device, alarm prediction method, and computer-readable recording medium

A plant operation support device for simulating an operation of a plant based on information obtained from the plant, includes: an operation condition setting part that sets an operation condition of the plant and a timing for applying the operation condition; and a transient state prediction part that predicts a transient state of the plant from a specific time point to the future in a case in which the operation condition of the plant set by the operation condition setting part is applied at the timing.

Plant operation support device, plant operation support method, and a program device

An alarm display apparatus includes an acquisition module, a plant simulation module, a prediction module, an actual measurement alarm determination module, an estimation alarm determination module, a prediction alarm determination module and a display module. The display module displays, on the same screen, an actual measurement alarm information outputted from the actual measurement alarm determination module, an estimation alarm information outputted from the estimation alarm determination module and an prediction alarm information outputted from the prediction alarm determination module.
