Figure 6
The vertical axis is labeled “Train Number,” ranging from 78 percent to 92 percent in increments of 2 percent. The horizontal axis is labeled “Cases,” ranging from 1 to 20 in increments of 1. The “Case F O” curve, a solid line with circular markers, starts at (1, 86), falls slightly to (2, 83.941), rises to (3, 87.113), and dips marginally to (6, 85.013), then rises sharply to a peak at (7, 90.356). After a short fall to (8, 85.241), it fluctuates between (9, 87.102) and (15, 88.572), dips again at (17, 84.304), and climbs gradually to end near (20, 91.032). The “Case N F O” curve, also a solid line in a different color with circular markers, begins at (1, 85.012), declines to (2, 81.876), and rises again near (3, 87.274). It falls steadily to (4, 80.745), recovers to (5, 85.112), and fluctuates slightly through (6, 84.926) and (7, 84.702). The curve dips to (8, 83.112), rises again to (9, 86.045), and continues alternating between minor peaks and troughs until it reaches (17, 79.043), the lowest point. It then rises modestly and ends at (20, 83.646). Note: All numerical data values are approximated.Capacity utilization of the case FO and NFO. Source: Author’s own work
