| description | PROBLEM TO BE SOLVED: To easily analyze the quality of a product by displaying a combination of operating condition where the change of the quality to the change of the operation is relatively large, a combination of operation factors effective for quality improvement is extracted automatically, and a predetermined quality level is established, of all the combination of operation factors. SOLUTION: The operating condition is divided into a plurality of ranges; an operating condition mesh obtained by combining them among a plurality of operation factors is created, and a quality index is calculated based on the probability density of the quality data in each operating condition mesh. The maximum value and minimum value are selected from the quality indices of operating condition meshes in the combination of all operation factors, and the combination of the operation factors with large influence factor calculated from the difference between the maximum and minimum values is selected and presented. A predetermined target quality index is compared with the quality index of the operating condition mesh in the combination of the operation factors having a relatively large effect for quality improvement; the operating condition mesh achieving the target quality and the operating condition corresponding to the mesh are selected, and guidance is performed.
