A review of the literature on control charts for multivariate quality control (MQC) is given, with
a concentration on developments occurring since the mid-1980s. Multivariate cumulative …

In this paper we discuss the basic procedures for the implementation of multivariate
statistical process control via control charting. Furthermore, we review multivariate …

We propose a statistical process control scheme that can be implemented in industrial
practice, in which the quality of a process can be characterized by a general linear profile …

A multivariate exponentially weighted moving average control chart can be used to improve
the detection of small shifts in multivariate statistical process control. Recommendations are …

We investigate the effects of non-normality on the statistical performance of the multivariate
exponentially weighted moving average (MEWMA) control chart, and its special case, the …

A Markov chain approximation is used to determine the run length performance of a
multivariate statistical process control chart. The Markov chain approach is widely used in …

Multivariate control charts are considered for the simultaneous monitoring of the mean
vector and covariance matrix when the joint distribution of process variables is multivariate …

This paper proposes methods for determining the optimal choice of design parameters
(including control limits, sample size, exponential weights for past observations, and …

A control chart is proposed to effectively monitor changes in the population variance-
covariance matrix of a multivariate normal process when individual observations are …

The complexity of ozone (O 3) formation mechanisms in the troposphere makes the fast and
accurate modeling of ozone very challenging. In the absence of a process model, principal …
