Abstract:
To provide an estimation device, a prediction device, a control device, an estimation system, a prediction system, a control system, an estimation program, a prediction program, a control program, an estimation method, a prediction method, and a control method which are capable of estimating an index value to act as a measure of generation of scale from water quality information being readily measurable during operation. An aspect of the present invention provides an estimation device which estimates a scaling index value of a water system. The estimation device includes: a water quality information acquiring unit; a relational model information acquiring unit; and an estimating unit. The water quality information acquiring unit acquires water quality information including two or more water quality parameters selected from the group consisting of at least pH, a cationic demand, a residual chlorine concentration, temperature, electrical conductivity, an amount of floating suspended solids, turbidity, and chromaticity of the water system. The relational model information acquiring unit acquires relational model information including a relational model indicating a relationship between a scaling index value which is calculated from a function created in advance of concentrations of ions constituting scale that may be formed in the water system and the water quality parameters. The estimating unit calculates an estimated scaling index value based on the water quality information and the relational model information.
