Object-oriented for calculating the control amount of the monitoring means, the storage means for storing the operation result data of the plant, and the sensor means constructed by
A control means constructed by a program and a corresponding sensor means provided for each device to be monitored and controlled.
Object-oriented professional that acquires the process data from
Which is constructed by gram,
In addition to acquiring the above-mentioned operation record data,
Data and process data acquired from the corresponding sensor means
Data is required to calculate the control amount of the device for monitoring and control.
Interface to input to the control means as transparent data
Means and operating performance data required for predictive calculation of the heat load of the plant.
Object-oriented program for extracting data from the storage means
Interface hand for heat load prediction built by Gram
Stage, the operating condition data of the plant, and the heat load prediction
Interface data extracted by the interface means
To predict the heat load of the plant using
Thermal load prediction constructed by object oriented program
And a heat load prediction calculation result from the heat load prediction means.
Driven by an object-oriented program
Planning interface means, specification data for each device, and the operation planning interface
Using the prediction calculation result of the heat load obtained by
And an object that calculates the operation plan of the plant
As an operation planning means constructed by the orientation program
A computer that records a program for operating the computer.
Computer-readable recording medium.
