Quality prediction apparatus, quality prediction method, and product manufacturing method

摘要

PPROBLEM TO BE SOLVED: To provide a quality prediction device and a quality prediction method for predicting the quality of a product with a high degree of accuracy and a method for manufacturing the product using the quality prediction method. PSOLUTION: This quality prediction device is provided with: a result database (13) in which the quality data of a product manufactured in the past and feature amount data calculated from operation data in manufacturing the product are stored so as to be associated with each other; a feature amount calculation means (2) for calculating the feature amount data from the operation data in manufacturing the product whose quality should be predicted; and a quality prediction value calculation means (3) for calculating the similarity of the feature amount data calculated by the feature amount calculation means (2) and the respective feature data stored in the result database (13), and for calculating the quality prediction value of a product from the similarity and the quality data in the result database (13).
