2-3. Ark Tec assembles PC computers for private clients. The orders for the next four quar- ters are 400, 700, 500, and 200, respectively. ArkTec has the option to produce more than is demanded for the quarter, in which case a holding cost of $100 per computer per quarter is incurred. Increasing production from one quarter to the next requires hiring additional employees, which increases the production cost per computer in that quarter by $60. Also, decreasing production from one quarter to the next would require laying off employees, which results in increasing the production cost per computer in that quarter by $50. How should Ark Tec schedule the assembly of the computers to satisfy the demand for the four quarters?
