PROBLEM TO BE SOLVED: To provide a method that executes a dispersion analysis without prolonging time necessary for Monte Carlo analysis and with high precision. SOLUTION: The method has a variation distribution estimation procedure of computing a normal distribution parameter according to sample data for every standard-limited variable parameter, and a Monte Carlo analysis procedure of repeating more than once a step of deciding a randomized value for every standard-limited variable parameter and executing a simulation using such values. In the value decision for every standard-limited variable parameter of the Monte Carlo analysis procedure, the randomized value is temporarily decided according to the normal distribution parameter, and if the temporary value is within the standard range, it is used as a formal value, or if the temporary value is outside the standard range, a temporary uniform-randomized value within the standard range is produced again and used as a formal value.
