RESPONSE SURFACE MODELING DEVICE, RESPONSE SURFACE MODELING METHOD, AND RESPONSE SURFACE MODELING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To create a response surface model without a drawback of creating a linear model that does not approximate to samples belonging to a partitioned region. PSOLUTION: There are provided: an input part 1 that inputs samples composed of factor values and a response value; a sample placement part 21 that places the samples in spaces, the samples being input by way of the input part 1; a linear modeling part 230 that creates the linear model for each region, based on coordinate values of the samples belonging to the region; a region partition part 22 that partitions the linear model, based on the samples belonging to the region; a partition region determination part 221 that determines whether it is possible to partition the region, based on the samples belonging to the region to be partitioned; and a modeling part 23 that creates a response surface model by placing each linear model in the spaces when the partition region determination part 221 has determined that partition is impossible in all the regions.
