Suppose you have been given responsibility for developing the six-month aggregate production plan at Soda Galore, a manufacturer of soft drinks. Your company makes three types of soft drinks: regular, diet, and super-caffeinated. Fortunately, all three types are made using the same production process, and the costs related to switching between the three types are so minimal that they can be ignored. Thus, you can treat your problem as an aggregate planning exercise where the planning unit is cases of soft drinks, regardless of what types of drinks they are. The S&OP team has developed a forecast of demand for the first six months of the year as shown in Table 13-3. The S&OP team has also provided you with the cost data shown in Table 13-4. The material cost of a case of soda is the same regardless of whether it is produced in regular time or overtime.
