论文摘要
在现代制造业和服务行业中，监测过程的几个相关质量特征很常见。尽管对监视多元过程的平均值已经引起了很多关注，但是没有多少控制图可用于监视协方差矩阵。本文介绍了有关控制图表的文献的全面概述，以监视多元统计过程监视（MSPM）框架中的协方差矩阵。它归类了以前出现在文献中的研究。我们重点介绍了研究的挑战领域，并为将来的研究提供了一些指导。
Monitoring several correlated quality characteristics of a process is common in modern manufacturing and service industries. Although a lot of attention has been paid to monitoring the multivariate process mean, not many control charts are available for monitoring the covariance matrix. This paper presents a comprehensive overview of the literature on control charts for monitoring the covariance matrix in a multivariate statistical process monitoring (MSPM) framework. It classifies the research that has previously appeared in the literature. We highlight the challenging areas for research and provide some directions for future research.
