Modify the original Grand Prix example by increasing the demand at each regions by 200, so that total demand is well above total plant capacity. However, now interpret these “demands” as “maximum sales,” the most each region can accommodate, and change the “demand” constraints to become “≤” constraints, not “≥” constraints. How does the optimal solution change? Does it make realistic sense? If not, how might you change the model to obtain a realistic solution?
