A manager has prepared a forecast of expected aggregate demand for the next six months. Develop an aggregate plan to meet this demand given this additional information: A level production rate of 100 units per month will be used. Back orders are allowed, and they are charged at the rate of $8 per unit per month. Inventory holding costs are $1 per unit per month in ending inventory. Determine the cost of this plan if regular time cost is $20 per unit and beginning inventory is zero.

Beginning Inventory | 0 | 20 | 20 | 0 | -10 | -10 |
Production | 100 | 100 | 100 | 100 | 100 | 100 |

Holding | 20 | 20 | ||||
Backorder | 80 | 80 |
Total Cost = 2000*6 + 20*2 + 80*2 = $12200
