Most robust control charts in the literature are for monitoring process location parameters, such as mean or median, rather than process dispersion parameters. This paper develops a new robust control chart by integrating a two-sample nonparametric test intothe effective change-point model. Our proposed chart is easy in computation, convenient to use, and very powerful in detectingprocess dispersion shifts
