The president of Hill Enterprises, Terri Hill, projects the firm's aggregate demand requirements over the next 8 months as follows: January 1,400 May 2,200 February 1,600 June 2,100 March 1,800 July 1,900 April 1,700 August 1.900 Her operations manager is considering a new plan, which begins in January with 200 units of inventory on hand. Stockout cost of lost sales is $125 per unit. Inventory holding cost is $20 per unit per month. Ignore any idle-time costs. The plan is called plan A. Plan A: Vary the workforce level to execute a strategy that produces 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 $50 per unit. The cost of laying off workers is $80 per unit. Evaluate this plan. (Enter all responses as whole numbers.) Note: Both hiring and layoff costs are incurred in the month of the change. For example, going from 1,600 in January to 1,400 in February incurs a cost of layoff for 200 units in February.
