Abstract

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.

First claim

What is claimed is:

1 . An information processing device comprising:
a calculation unit configured to, when a worker executes an operation on an actual plant, generate 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 generate 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; and an evaluation unit configured to, based on the first calculation result and the second calculation result, evaluate the operation that is executed by the worker.

2 . The information processing device according to claim 1 , wherein the evaluation unit is configured to
receive choosing of a second calculation result serving as a reference of evaluation from the second calculation results corresponding to the operation pattern plans, respectively, calculate a similarity between the chosen second calculation result and the first calculation result, and evaluate that the similarity is rated high when the similarity is at or above a threshold and evaluate that the similarity is rated low when the similarity is under the threshold.

3 . The information processing device according to claim 1 , wherein the calculation unit is configured to
acquire the state of the actual plant after execution of a plurality of operations by the worker within a given time, and with respect to each of the operation pattern plans corresponding to the state of the actual plant that is acquired before or after execution of the first one of the operations, generate each of the second calculation results obtained by calculating a behavior of the actual plant after elapse of the given time from the first operation using the virtual plant, and the evaluation unit is configured to evaluate the operation that is executed by the worker by comparing the state of the actual plant after execution of the operations and each of the second calculation results.

4 . An evaluation method comprising:
when a worker executes an operation on an actual plant, generating 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 generating 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; and based on the first calculation result and the second calculation result, evaluating the operation that is executed by the worker.

5 . A computer-readable recording medium having stored therein an evaluation program that causes a computer to perform a process comprising:
when a worker executes an operation on an actual plant, generating 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 generating 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; and based on the first calculation result and the second calculation result, evaluating the operation that is executed by the worker.
