Make or Buy. A sudden increase in the demand for hard drives has left your company with insufficient capacity to meet demand. The company has seen monthly demand from its retailers for its Hard Disk Drives (HDD) and Solid State Drives (SDD) increase (see chart). Your production process for each unit involves three steps: fabrication, assembly, and shipping (see chart). The company also has the option to obtain additional units from a subcontractor, who has offered to supply the given capacity of units per month in any combination of HHD and SSD models at the given charge. For this price, the subcontractor will test and ship its models directly to the retailers without using your production process. What is the maximum profit? How many of each type should you fabricate yourself, and how many should you buy from the subcontractor? Note that demand may or not be met to achieve maximum profit.

	Monthly Hours Available	Hours/Unit (HDD)		Hours/Unit (SSD)				Demand	Subcontract Capacity
Fabrication	350	0.1		0.12			HDD	2215
Assembly	230	0.15		0.11			SDD	1512
Shipping	450	0.13		0.13			HDD+SSD		2282
	In House			Subcontracted
	HDD	SSD		HDD	SSD
Variable cost/unit	$75.00	$117.00		$79.00	$123.00
Retail Price	$82.00	$125.00		$82.00	$125.00
