Abstract: One-sided CUSUM control chart have been developed for detecting shifts in the shape parameter of a Pareto distribution. It was realised that the parameters of the CUSUM chart, the lead distance and the mask angle changes considerably for a slight shift in the shape parameter of the Pareto distribution. The ARL also changes considerably for a slight shift in the parameters of the distribution.

Keywords: one-sided CUSUM control charts; shift monitoring; Pareto distribution; shape parameter; lead distance; mask angle; ARL; average run length; SPC; statistical process control.
