Quality Abnormality Factor Analysis Support System

Abstract: In the present invention, a data storage unit stores a manufacturing condition for a product, a setting condition for facility equipment, and, as actual results data acquired from measurement equipment, time-series data for the time of manufacturing. A quality abnormality factor estimation calculation unit acquires a quality abnormality site of an abnormal product of which a quality evaluation value calculated from quality data exceeds an allowable range. The quality abnormality factor estimation calculation unit constructs a quality abnormality factor estimation model on the basis of the time series data as relates to a normal product group or on the basis of the manufacturing condition and setting condition, estimates a factor candidate for a quality abnormality on the basis of the constructed quality abnormality factor estimation model, and calculates the degree of relevance of the estimated factor candidate to the quality abnormality. A display information generation unit generates information for displaying, on a display unit, the quality data of the abnormal product, the quality abnormality site, the time series data or the manufacturing condition and setting condition, and the factor candidate and degree of relevance estimated and calculated by the quality abnormality factor estimation calculation unit.
