OPERATIONAL KNOW-HOW ESTIMATION DEVICE AND OPERATIONAL KNOW-HOW ESTIMATION METHOD

An object of the present invention is to reduce the workload of an operator to attach classification information necessary for estimating operational know-how of a water plant to time-series data of measured values and control values. An operational know-how estimation device includes a data acquisition unit configured to acquire target time-series, a classification information attachment unit configured to classify the target time-series data for each section and attach the classification information to the sections of the target time-series data, a know-how estimation unit configured to calculate a conditional probability that measured values and control values are simultaneously held for each piece of classification information, and estimate operational know-how based on the conditional probability, and a display control unit configured to create display information that supports state understanding or operation manipulation of a water plant based on the operational know-how and cause a display unit to display the display information.
