针对柔性自动化生产环境下实施统计质量控制 (SQC StatisticalQualityCon trol)的难点即质量数据不足的问题 ,将成组思想引入统计质量控制 ,以提高质量数据的先验性和质量数据之间的相关关系 ,提出了基于工序质量数据成组的成组统计质量控制 (GSQC GroupStatisticalQualityControl)技术。 Aiming at the difficulty of implementing SQC (Statistical Quality Control) in flexible automated production environment, ie, the problem of insufficient quality data, the idea of ​​group composition is introduced into statistical quality control so as to improve the correlation between the a priori quality data and quality data Based on the process quality data into a group of group statistical quality control (GSQC GroupStatisticalQualityControl) technology.
