The output means 81 outputs a diagram to a display device. The input means 82 accepts designation of a change point and a change condition for the displayed diagram. The constraint generation means 83 generates a constraint for an objective function used for optimization of the diagram based on the designation. The change proposal generation means 84 generates a change proposal for the diagram by optimizing the objective function based on the generated constraint. Then, the input means 82 accepts, for each change point, the designation of a hard constraint indicating a condition that must be satisfied, or a soft constraint indicating a condition that increases a penalty according to degree of unsatisfactory, as the designation of the change condition, the constraint generation means 83 generates the constraint according to the hard constraint or soft constraint, and the output means 81 outputs the change proposal of the diagram.
