A large Billings, MT feed mill Longhorn Processing, prepares its 6-month aggregate plan by forecasting demand for 50-LB bags of cattle feed as follows: January, 1,000 bags: February 1,500; March 1,650: April 1,550; May 1900; and June 1,500. The feed mill plans to begin the new year with no inventory left over from the previous year, and backorders are not permitted. It projects that capacity (during regular hours) for producing bags of feed will remain constant at 800 until the end of April, and then increase to 1,100 bags per month when the planned expansion is completed on May 1st. Overtime capacity is set at 300 bags per month until the expansion, at which time it will increase to 400 bags per month. A friendly competitor in Grand Forks, ND is also available as a backup source (subcontractor) to meet demand but can provide only 500 bags per month during the 6-month period. Cost on regular time per bag is $12.50; Overtime cost is $6.25 extra; subcontracting cost $21.50. Carrying cost is 1.75 per bag.
