Abstract

A test planning device builds up a boiler model data by using a plurality of input parameters of the boiler classified into a plurality of parameter groups. The apparatus selects one of the plurality of parameter groups as a parameter group subjected to learning, presents test conditions in which an input parameter thereof is defined as a variable, and an input parameter of a parameter group not subjected to learning is defined as a fixed value. The device modifies the model data on the basis of the result of comparison between an actual process value and a virtual process value using the present test conditions, selects a new parameter groups subjected to learning, and presents new test conditions which use the input parameter of the test conditions in which the input parameter of the previous parameter group subjected to learning is optimal, as the fixed value.
