2. 5-2 Wyndor (Before What-If Analysis)

3. 5-3 Using the Spreadsheet to do Sensitivity Analysis The profit per door has been revised from $300 to $200. No change occurs in the optimal solution.

4. 5-4 Using the Spreadsheet to do Sensitivity Analysis The profit per door has been revised from $300 to $500. No change occurs in the optimal solution.

5. 5-5 Using the Spreadsheet to do Sensitivity Analysis The profit per door has been revised from $300 to $1,000. The optimal solution changes.

6. 5-6 Using Solver Table to do Sensitivity Analysis

7. 5-7 Using Solver Table to do Sensitivity Analysis

8. 5-8 Using the Sensitivity Report to Find the Allowable Range The solution Allowable range (Solution stays the same)

9. 5-9 Graphical Insight into the Allowable Range The two dashed lines that pass through the solid constraint boundary lines are the objective function lines when P D (the unit profit for doors) is at an endpoint of its allowable range, 0 ≤ P D ≤ 750.

10. 5-10 Using the Spreadsheet to do Sensitivity Analysis The profit per door has been revised from $300 to $450. The profit per window has been revised from $500 to $400. No change occurs in the optimal solution.

11. 5-11 Using the Spreadsheet to do Sensitivity Analysis The profit per door has been revised from $300 to $600. The profit per window has been revised from $500 to $300. The optimal solution changes.

14. 5-14 Using Solver Table to do Sensitivity Analysis

15. 5-15 Using the Spreadsheet to do Sensitivity Analysis The hours available in plant 2 have been increased from 12 to 13. The total profit increases by $150 per week.

16. 5-16 Using the Spreadsheet to do Sensitivity Analysis The hours available in plant 2 have been further increased from 13 to 18. The total profit increases by $750 per week ($150 per hour added in plant 2).

17. 5-17 Using the Spreadsheet to do Sensitivity Analysis The hours available in plant 2 have been further increased from 18 to 20. The total profit does not increase any further.

18. 5-18 Using Solver Table to do Sensitivity Analysis

19. 5-19 Usage of the resource (Left-hand-side of constraint) Allowable range (Shadow price is valid) Increase in objective function value per unit increase in right-hand-side (RHS) ∆Z = (shadow price)(∆RHS) Using the Sensitivity Report

20. 5-20 Graphical Interpretation of the Allowable Range

21. 5-21 Using the Spreadsheet to do Sensitivity Analysis One available hour in plant 3 has been shifted to plant 2. The total profit increases by $50 per week.
