Abstract: A control device performs control of a culture condition in production of an organic compound by a fermentation method. The control device executes processing a plurality of times to acquire culture data, to calculate, using the acquired culture data, a plurality of candidates for a culture condition set in advance, and a linear model set in advance that outputs a production amount of an organic compound at a future time, the production amount at the future time for each of the candidates, to determine an optimum candidate out of the candidates using the calculated production amount at the future time for each of the candidates and a target production amount of the organic compound at the future time set in advance, and to change the culture condition to the determined candidate. The linear model and the target production amount are set for each time.
