摘要
介绍了对多个质量特性进行工序控制的质量控制方法,指出多元质量控制问题不能采用一元质量控制图进行,给出了常见的多元质量控制图的计算公式并以实例加以说明.
The methods for process control of Multivariate quality characteristics are introduced in this paper. The authors point out that the approach to univariate quality control cannot be applied to deal with multivariate quality control. The computer formula for the ordinary multivariate quality control chart and an example are given in the paper.
