Figure 4
The rectangular chart shows a shaded region and two plotted lines. The horizontal axis at the bottom is labeled “increment” and displays percentage labels in sequence as “1 percent”, “2 percent”, “3 percent”, “4 percent”, “5 percent”, “6 percent”, “7 percent”, “8 percent”, “9 percent”, “10 percent”, “15 percent”, and “20 percent”. The vertical axis is labeled “maximum budget” and ranges from 1600 to 21600 in an interval of 2000. The legend of the graph shows “maximum budget” for the shaded region and “solution budget” for the horizontal line. The solution budget is a horizontal line passing through the maximum budget of 16600. The shaded area of the maximum budget is spread horizontally, rises slightly from the solution budget, till the maximum budget of 20000. Note: All numerical data values are approximated.Graphical representation of the OA range of solutions. Source: Created by authors
