How to analyze sensitivity in Excel
1. Before you click OK, select Sensitivity in Reports.
Below you can find the optimal solution and the sensitivity report.
Optimal is to order 94 bicycles and 54 motorcycles. This solution gives a maximum profit of 25600. This solution uses all available resources (93000 units of capital and 101 units of storage). You can find these numbers in the Final Value column.
Cut the cost
Reduced cost tells us how much the target factor (unit profit) can increase or decrease before the optimal solution changes. If we increase the unit profit of Child Seats with 20 or more units, the optimal solution changes.
1. With a unit profit of 69, ordering 94 bicycles and 54 motorcycles is still optimal. Below you can find the optimal solution.
2. With a unit profit of 71, the optimal solution has changed.
Conclusion: ordering child seats is only profitable if you sell at least 70 units.
Ball price
The shadow price tells us how much the optimal solution can increase or decrease if we change the values to the right.
1. With 101 storage units available, the total profit is 25600. Below you can find the optimal solution.
2. With 102 storage units available, the total profit is 25700 (+100).
