摘要：
Among the variable sampling interval (VSI), variable sample size (VSS), and variable sample size and sampling interval (VSSI) T (2) charts that use two values of each adaptive parameter, a VSI T (2) chart is the most efficient chart to detect large shifts in the process mean vector while a VSSI T (2) chart is the most efficient one to detect small shifts. The statistical performance of the T (2) chart proposed in this paper very closely matches that of such VSI and VSSI T (2) charts for detecting the large and small shifts, respectively. The proposed chart uses two values of the sampling interval and three values of the sample size.
