Abstract
In a resin film manufacturing device according to an embodiment, a current state and a reward for a previously selected action are determined for each heat bolt based on a control error calculated from a thickness distribution of a resin film acquired from a thickness sensor. Then, control conditions, which are a combination of states and actions, are updated based on the reward, and a most appropriate action corresponding to the current state is selected from the updated control conditions. Then, the heater is controlled based on the most appropriate action.
