Suppose you have been given responsibility for developing thesix-month aggregate production plan at Soda Galore, a manufacturerof soft drinks. Your company makes three types of soft drinks:regular, diet, and super-caffeinated. Fortunately, all three typesare made using the same production process, and the costs relatedto switching between the three types are so minimal that they canbe ignored. Thus, you can treat your problem as an aggregateplanning exercise where the planning unit is cases of soft drinks,regardless of what types of drinks they are.
