A comparison study of effectiveness and robustness of control charts for monitoring process mean

► Compare 9 control charts including X-bar, CUSUM and SPRT types and basic, optimal and adaptive versions. ► Optimization design minimizes Average Extra Quadratic Loss for the best overall performance. ► Compare not only the detection effectiveness, but also the robustness in performance. ► We found that SPRT chart is more effective than CUSUM and X-bar charts by 58% and 126%, respectively. ► Optimization design and adaptive feature increase detection effectiveness by 29% and 35%, respectively.
