Problem 3 (20 points) Perform aggregate planning using the chase and the level strategy. Calculate and compare the total cost for both strategies. Two additional assumptions: Unmet demands in a period can be held and fulfilled in a future period. There is no cost associated with unmet demands (i.e., negative inventory has no costs). Beginning Inventory: 30 units Beginning Workforce: 5 workers Production Rate: 10 units/worker/period Regular Production Costs: $7.5/unit Inventory Costs: $21/unit/period Hiring Cost: $120/worker Firing Cost: $110/worker Period Demand 12 90 50 3 100 4 70 5 60
