Aggregate Planning: level capacity and chase demand strategy

A small manufacturing plant is considering their aggregate plan for the next fiscal year. They are limited to a maximum number of 40 FTEs each quarter. Their forecasted demand for next year is:

Quarter 1 2 3 4
Demand 12520 15000 11880 14680

They do not consider hiring or firing costs but have the following production parameters.

Labor Standard = 1.6 hours/item
Regular Time Labor Cost = $10/hour
Beginning Annual Inventory Level = 500
Ending Annual Inventory Level = 500
Unit Inventory Carrying Cost = $4/item/quarter
Any overtime labor in a quarter is time and a half.
(Assume 40 hours/week, 52 weeks/year, and 4 quarters/year.)

1. For next fiscal year, find their annual regular time direct labor cost and their overtime direct labor cost based on a level capacity aggregate planning strategy.

2. For next fiscal year, find their annual regular time direct labor cost and their overtime direct labor cost based on a chase demand aggregate planning strategy.
