The present invention relates to optimization analysis achieving a target value and provides a device, method and program ensuring improved analysis efficiency and analysis accuracy. The device includes an analysis unit (CPU 14), an evaluation unit (CPU 14) and a condition modification unit (CPU 14). The analysis unit executes an analysis with analysis conditions imparted thereto. The evaluation unit evaluates the analysis results. The condition modification unit modifies the analysis conditions imparted to the analysis unit, based on the evaluation results. An optimum solution is thus derived by performing one or more analyses through the modification of the given analysis conditions.
