2.- To find the best parameters (optimization) to reach a given in-control ARL and to minimize the out-of-control ARL for a given shift.
3.- To plot an ARL chart, showing a comparison of performance versus the standard Xbar control chart.
In this application d = (m1 - m0) / sigma0. And r = sigma1 / sigma0
