PROBLEM TO BE SOLVED: To provide a structure optimization support system capable of quantitatively evaluating the stochastic characteristics of a structure response affected by the dispersion of a structure parameter with a sensitivity coefficient by finding the sensitivity coefficient while using finite element sensitivity analysis, and displaying the sensitivity coefficient on an effective means, with which a designer can easily judge a design guideline. SOLUTION: By applying this system to a stochastic/statistic method such as primary approximation secondary moment method while using the found sensitivity coefficient, a standard deviation is found and the fluctuation quantity of a structure is evaluated.
