Manufacturing process analysis apparatus, manufacturing process analysis method, and recording medium storing manufacturing process analysis program

摘要

Based on the data indicating the state of the manufacturing process collected in time series, problems existing in the manufacturing process are analyzed with higher accuracy. The manufacturing process analysis apparatus (30) has a strong invariant compatibility for each shift time with respect to the manufacturing condition value (360) and the quality value (361) measured in time series in the process of manufacturing a product. A calculation unit (31) for calculating the length, a shift time specifying unit (32) for determining, as a specific shift time, a shift time for which the strength of invariant suitability satisfies a standard, a quality value, and a quality value were measured And an analysis unit (33) for analyzing the state of the manufacturing process based on the manufacturing condition value at a time that is earlier than the specific shift time with respect to the time.
