From Figures 5-4 to 5-7.
1. List and describe each decision variable
2. List and describe each of the constraints
3. What is the solution? (i.e., values for each decision variable and the total costs)
4. How does the solution (decision variables and costs) change if the South American Demand Region is no longer operational (note: European demand still needs to be satisfied)? -
5. Given the Scenario in question 4, where would you add capacity to reduce total costs? WHY?
