Apparatus and method for optimizing plant inspection plan

摘要

PROBLEM TO BE SOLVED: To quantify the uncertainty of the deterioration state by a prediction model in consideration of the uncertainty of the future operation status of the plant, and to consider the risk, when the equipment fails, to improve the accuracy of the prediction model, and to inspect it. Provided is a plant inspection plan optimization device and method for optimizing inspection points and methods from the viewpoint of cost. SOLUTION: A plant operation prediction unit that predicts variations in plant operation, a variation in plant operations, and a probability distribution of deterioration conditions and prediction model parameters in a previous inspection are used to determine a plurality of planned inspection points in the plant. Using the deterioration probability distribution predictor that predicts the probability distribution of deterioration and the probability distribution of deterioration of multiple scheduled inspection locations, the inspection location optimization that selects the inspection location selected from the scheduled inspection locations according to the selection index An apparatus for optimizing a plant inspection plan, comprising: a unit and an output unit that presents a selected inspection location and inspection method.
