20210162362 · 2021-06-03 · ·

A flow reaction support apparatus includes a computing section and a determination section. The computing section generates a prediction data set by calculating a prediction result for each reaction condition whose reaction result is unknown, using measurement data. The computing section extracts the reaction condition of the prediction result closest to a target result as an extracted reaction condition. The determination section determines whether or not a difference between the reaction result under the extracted reaction condition and the prediction result is within an allowable range, and adds, in a case where the difference is not within the allowable range, reaction information in which the extracted reaction condition and the reaction result are associated with each other to the measurement data.
