Question 2: A manager is apptempting to put together an aggregate plan for the cmoing year. She has obtained a forecast pf expected demand for the planning horizon. The plan must deal with highly seasonal demand as can be seen from the following forecasts: Period 12345613 demand 190 230 260 280 210 170160200 180 Forecastes (units) The department has 20 full-time operators, each of whom can produce 10 units of output per period. Starting inventory is 40 units and 20% is safety stock. Inventory holding costs per unit Iliring and tranning cost $300 per worker Layoff cost Sooper worker Cost of subcontracting 530 per unit Regular-time cost $4 per hour Overtime cost Sc per hour Blacklog cost SIO per unit A. Determine the total cost of the plan for strategies as belows: a. Hiring and firing, no overtime b. Constant workforce c. Subcontracting B. Which startegy provided the lowest cost? We assume that an operator wo average 5 days per period and each operator works 8 hours/day. As given an operator con produce 10 units per period.
