Abstract:
The objective of this research was to compare the efficiency of detection the proportion control charts that are EXACT control chart, WILSON control chart and ISRT P EWMA control chart. This research considered the standard detection the proportion (p0) are 0.04, 0.06, 0.08, 0.1, 0.3 and 0.5. The shift of detection the proportion (Delta) are 0.00, 0.01, 0.03, 0.05, 0.07, 0.09, 0.1, 0.15, 0.2, 0.25, 0.3 and 0.5. Sample sizes (n) are 30, 50, 70, 100, 150 and 200. For each studied situation, the criterion used to compare the performance of the control chart was the Average Run Length when the process out of control (ARL1). The results of this study were as follows : EXACT, WILSON control chart are most efficient when = 0.5. ISRT P EWMA control chart is most efficient when 0.01 ≤ Delta ≤ 0.15 in case of all sample size.
