An optimum design management apparatus that analyzes response variable values from groups of predictor variable values, and performs optimization using the analysis result, which includes a predictor variable transmission unit that transmits groups of predictor variable values to be used for the analysis to the calculation node, and a response variable reception unit that receives response variable values of the analysis result from the calculation node. The optimum design management apparatus includes a response surface calculation unit that calculates at least one response surface from groups of predictor variable values and response variable values, an optimization calculation unit that updates groups of predictor variable values coming close to a predetermined optimization condition in the response surface to new groups of predictor variable values, and a control unit that repeats the processing continuing from the predictor variable transmission unit until a predetermined end condition is fulfilled.
