PPROBLEM TO BE SOLVED: To calculate the set of overall optimum solutions satisfying a prescribed drive standard. PSOLUTION: A multiple-purpose optimum solution set calculation device includes: an input unit 1 for input of the set of the partial optimum solutions of design variables, which minimize or maximize the combination of a plurality of objective functions having a calculated trade-off relation based on each of the plurality of combinations of a plurality of driving states, and the values of the drive conditions of each step of a drive standard, which is configured of a plurality of steps and in which the drive conditions of the objects of driving is different from each other for each step; an achievement value map creation unit 201 for creating an achievement value map in which the partial optimum solution, in the range of the driving states, is predictable, based on the partial optimum solution to be extracted for each of the plurality of combinations of the plurality of driving states; an achievement value extraction unit 202 for extracting an achievement value from an achievement value map created for each of the items of the driving states; and an overall optimum solution calculation unit 21 for calculating the set of the overall optimum solutions from a summation achievement value to be calculated by integrating the achievement values for each step of the drive standard.
