控制图第7部分:多变量控制图

[中文适用范围]： 本文档描述了统计过程控制 (SPC) 中多元控制图的构建和使用，并建立了使用和理解这种控制图通用方法的方法，其中所测量的特征来自变量数据。 本文件中未介绍主成分分析 (PCA) 和偏最小二乘法 (PLS) 在多元统计过程控制领域的使用。 注：本文件描述了在实践中应用的多元控制图的当前技术水平如今。 它没有描述该主题的科学研究现状。 [外文原描述]： This document describes the construction and use of multivariate control charts in statistical process control (SPC) and establishes methods for using and understanding this generalized approach to control charts where the characteristics being measured are from variables data. The use of principal component analysis (PCA) and partial least squares (PLS) in the field of multivariate statistical process control is not presented in this document NOTE The document describes the current state of the art of multivariate control charts that are being applied in practice nowadays. It does not describe the current state of scientific research on the topic.
