• in the policy generation step, generate a plurality of pieces of the control policy trend information;
• in the result acquisition step, acquire culture result index corresponding to the target quality information over the predetermined culture time by executing the culture behavior prediction step using the optimum value of the specific culture condition at each culture time point determined in the optimal condition determination step with respect to each of the generated pieces of control policy trend information;
• and
• in the policy selection step, select one or more pieces of the control policy trend information conforming to the target quality information among the plurality of pieces of control policy trend information on a basis of the culture result index acquired with respect to each of the pieces of control policy trend information.

5:
