Figure 7
The horizontal axis ranges from 1 through 9 with unit increments. The vertical axis ranges from 0 to 35 with 5 unit increments on the left and 16250 to 16650 with increments of 50 units. The legend of the graph includes “SUPPLIER 1”, “SUPPLIER 2”, and “SUPPLIER 3” in blue, red, and green bars. The legend also includes a green line for T P C. Supplier 1 bars are the longest bars, and decrease along the horizontal axis from 1 to 9. The other two bars increase from 1 to 9. The total supply line increases from 22 on the left vertical axis to 30, then remains almost flat at around 31 on the left vertical axis. Note: All numerical data values are approximated.Total purchasing cost when varying the constraint of the maximum quantity assignable to Supplier 1. Note(s): Considered the optimal solution found by the linear BWM. Source: Created by authors
