ActiveStatistical methods in monitoring process capability and performance—Part 6：Process capability statistics for characteristics following a multivariate normal distribution
生产过程能力和性能监测统计方法 第6部分：多元正态过程能力分析
Application Summary AI generated
This standard provides statistical methods for calculating process capability indices when multiple correlated quality characteristics follow a multivariate normal distribution. It is applied in manufacturing industries where product quality depends on several interrelated variables, such as chemical composition, dimensional tolerances, or mechanical properties. The standard enables engineers to assess overall process performance and capability in complex production environments where univariate analysis would be insufficient.
