                  a discussion on the ). Both were considered as the  measures the
                  control chart’s performance for specific shifts, whereas the  measures the
                  overall  performance  of  the  control  chart.  Only  the  latter  is  shown  here  to
                  conserve  space.  The  proposed  methods  are  compared  to  the  traditional
                  methods and the chart with the lower  performs best. It was found that
                  for the SRR2-of-(h+1) scheme, the proposed control schemes perform better than
                  the traditional control schemes for any ℎ value regardless of the sample size
                  for both zero-state and steady-state modes. For the IRR2-of-(h+1) schemes, for
                  both zero-state and steady-state modes, the proposed BTXII control schemes
                  are slightly more sensitive than the IRR2-of-(h+1) traditional control schemes (see
                  Figures 3 and 4).
