Procedures for Monitoring the Process Mean and Variance with One Control Chart

초록

Two control charts are usually required to monitor both the process mean andvariance. In this paper, we introduce control procedures for jointly monitoring theprocess mean and variance with one control chart, and investigate efficiency of the introduced charts by comparing with the combined two EWMA charts. Our numerical results show that the GLR chart, the Omnibus EWMA chart, and the Interval chart have good ARL properties for simultaneous changes in the process mean and variance.
