Popis: In statistical process control (SPC) there are two situations where monitoring multivariate is needed. One is that all of the variables monitored are product ones. The other is that the variables monitored are some product and process ones. In these cases, there are correlations among the variables. Therefore, application of multivariate control charts to such process control is useful.
