摘要

PROBLEM TO BE SOLVED: To more properly grasp a situation of a manufacturing process.SOLUTION: A method for manufacturing a target product containing an organic substance from a raw material by a predetermined manufacturing process has: a first step of receiving transmitted light or diffused reflected light to be emitted from a measuring object whose amount of the raw material or the target product varies according to progress of the manufacturing process by irradiating the measuring object with wideband light and acquiring an absorbance spectrum of the measuring object; a second step of extracting two of more feature quantities showing features of the measuring object from the absorbance spectrum obtained in the first step; and a third step of controlling the manufacturing process based on the feature quantities extracted in the second step. Thus, the two or more feature quantities showing the features of the measuring object are extracted from the absorbance spectrum of the measuring object, and a situation of the manufacturing process can be more accurately grasped based on the feature quantities.
