| If the quality of a process is described using a linear functional relationship between the response variable and independent variables, such a relationship is called the profile. Today, with the development of manufacturing technologies, multistage processes have found a special position in manufacturing companies and industries. In this paper, we consider a multistage process with AR(1) auto-correlated simple linear profile in each stage and address the effect of both auto-correlation and cascade property on the performance of common monitoring procedures. To eliminate the effect of auto-correlation, we used a transformation method as a remedial measure at first. Then, an approach based on the U statistic is applied to remove the cascade property. Next, a modified T2 control chart is proposed to monitor the process in the second stage. The performance of the proposed control chart is evaluated in terms of average run length criterion. The simulation studies show that the proposed control chart perform satisfactorily. | ||
