Question 104 3 pts Chapter 6, Aggregate Production Planning Use the following data for the next FOUR questions: Forecast demand for an item is given below: January February March April May June Demand 15,000 12,000 15,000 8,000 18,000 8,000 Inventory holding cost is $1/unit/month (based on ending inventory). Hiring cost is $2,000 per person hired. Firing cost is $1,000 per person fired. The straight-time cost of a permanent employee is $2,500/month Overtime is 1.5 times straight-time labor cost. Each worker can produce 50 units per month on straight time. The permanent workforce consisted of 200 workers at the end of December Inventory at the beginning of January is 2.500 units. Use the following schedule to find the least-cost "chase aggregate Inventory at the beginning of January is 2,500 units. Use the following schedule to find the least-cost "chase" aggregate production plan with a constant workforce size of 250. (Management permits hiring or firing on January 1, but requires that workforce thereafter be held constant.) Use overtime to vary production when necessary.
