Abstract

A method of estimating quality factors includes a step of acquiring quality data indicating a quality of a product with respect to normal quality and m types of quality defects, m being two or more, a step of acquiring operating data of a manufacturing process, a step of creating quality evaluation data for each of the m types of quality defects, a step of acquiring m types of models generated using the quality evaluation data and determining a feature importance indicating the magnitude of contribution of an operating variable for each of the m types of models, and a step of identifying the operating variable that is estimated to be a major factor for at least one of the m types of quality defects by comparing the feature importance of the m types of models.
