The president of Hill Enterprises, Terri Hill, projects the firm€™s aggregate demand requirements over the next 8 months as follows:

Her operations manager is considering a new plan, which begins in January with 200 units on hand. Stockout cost of lost sales is $100 per unit. Inventory holding cost is $20 per unit per month. Ignore any idle-times costs. The plan is called plan A.
Plan A: Vary the workforce level to execute a €œchase€ strategy by producing the quantity demanded in the prior month. The December demand and rate of production are both 1,600 units per month. The cost of hiring additional workers is $5,000 per 100 units. The cost of laying off workers is $7,500 per 100 units. Evaluate thisplan.
