1. An optimization analysis device deriving an optimum solution from a pre-specified range by executing analysis with plural analysis conditions, the device comprising: an analysis unit executing an analysis with analysis conditions imparted thereto, parameters of the analysis conditions for obtaining an optimum solution being imparted prior to said analysis; an evaluation unit evaluating analysis results of the analysis unit; and a condition modification unit modifying the analysis conditions imparted to the analysis unit by selecting from said plural analysis conditions imparted prior to said analysis when said analysis results are not within the pre-specified range, wherein the analysis unit, linking with a plurality of databases, is connected directly or via a web connection to a database corresponding to an analysis condition that is selected from the imparted plural analysis conditions, and the analysis unit gives the analysis results from the corresponding database by using parameters of the selected analysis condition, the analysis unit links other analysis systems and causes the other analysis systems to execute other analysis with different analysis conditions, or execute the analysis again with other analysis conditions, based on the analysis results given from the corresponding database; said modifying adds a priority order to the analysis conditions, and selects the analysis conditions in the priority order; and the analysis unit iteratively executes the analysis using the analysis conditions in said priority order until the optimum solution within the pre-specified range is derived, and stores the derived optimum solution in a storage.
