# Question: Jones Inc is preparing an aggregate production plan for next

Jones Inc. is preparing an aggregate production plan for next year. The company expects demand to be 1,000 units in quarter 1; 2,000 units in quarter 2; 4,000 units in quarter 3; and 3,000 units in quarter 4. The company will have 100 units in inventory at the beginning of the year and desires to maintain at least that number at the end of each quarter as safety stock. Other information:
Regular production labor cost = \$100 per unit
Overtime production cost per unit = \$150
Inventory carrying cost = \$25/unit/quarter based on quarter-ending inventory
Hiring Cost = \$2,000 per worker
Firing/layoff cost = \$3,000 per worker
Beginning # of workers = 15
Each worker can produce 100 units per quarter.
a. What is the total cost of a level plan?
b. What is the total cost of a chase plan utilizing hiring and firing?
