Abstract
This paper considers the problem of contamination in process distribution as well as identifying a combination of variables which are responsible for the change in process. Three interactive steps for the control of mean vector in a contaminated multivariate normal process are proposed. The first step is to estimate the process parameters by robust statistics. The control chart is introduced in the second step. In the third step, we consider a change point model to monitor a step change in mean vector. The simulation results reveal the efficiency of model for detecting a specific step change in the process.
