摘要
A failure occurrence index for each variable section is derived, and a cause of the process failure is identified and visualized. The method includes the steps of obtaining first data including quality inspection result data measured by at least one sensor installed in each of a plurality of processes and second data including process data, A step of preprocessing individual data of each of the first data and the second data, generating analysis target data by integrating the preprocessed individual data, and analyzing the poor data based on univariate analysis Analyzing the cause according to individual variables, and deriving the failure cause index according to the analysis result based on the univariate analysis.
