Quality control device, quality control method, and program

A quality control method of controlling quality of a product manufactured through a plurality of processes, comprising:

• generating a prediction model to predict quality of a product with respect to unknown process data by performing learning using known process data obtained from the plurality of processes and a measured value of quality of the product with respect to the known process data as learning data;
• deriving a predictive value of quality of each of a plurality of products, which are manufactured after the prediction model is generated, on the basis of the prediction model using process data of the plurality of products as input data;
• and
• deciding the product for which the predictive value having the smallest margin with respect to a preset standard is obtained as an inspection target, among the plurality of predictive values of quality obtained in the deriving of the predictive value of quality.

A non-transitory computer-readable storage medium storing a program of controlling quality of a product manufactured through a plurality of processes, the program causing a computer to execute:

• generating a prediction model to predict quality of a product with respect to unknown process data by performing learning using known process data obtained from the plurality of processes and a measured value of quality of the product with respect to the known process data as learning data;
• deriving a predictive value of quality of each of a plurality of products, which are manufactured after the prediction model is generated, on the basis of the prediction model using process data of the plurality of products as input data;
• and
• deciding the product for which the predictive value having the smallest margin with respect to a preset standard is obtained as an inspection target, among the plurality of predictive values of quality obtained in the deriving of the predictive value of quality.
