Figure 10.
Four horizontal panels are labelled Buffer, Dual Sourcing, Employee, and no measures. Each panel shows several lines plotted across a horizontal time axis from 0 to about 70 and a vertical scale from 0 to about 1. A grey solid line fluctuates slightly around the value near 1 at the beginning, declines after about time 20, and then increases again toward about 1 later in the timeline. Blue dotted vertical lines appear near time 20 and near time 35. A blue dotted horizontal line appears at the level near 1. A green dashed line remains near 0 at the beginning and then increases toward about 1 later in time. An orange dashed line starts near 1 and decreases toward 0 after about time 20. In the Dual Sourcing panel, a red dashed curve forms a dip below the level near 1 between about time 20 and time 35 before rising again. The patterns across the four panels show similar line movements with differences in the timing and shape of the curves.Analysis of the fit of the Sigmoid curves
