Question

Vollmer Manufacturing makes three components for sale to refrigeration companies. The components are processed on two machines: a shaper and a grinder. The times (in minutes) required on each machine are as follows:

Machine
Component	Shaper	Grinder
1	6	4
2	4	5
3	4	2

The shaper is available for 120 hours, and the grinder for 110 hours. No more than 200 units of component 3 can be sold, but up to 1,000 units of each of the other components can be sold. In fact, the company already has orders for 600 units of component 1 that must be satisfied. The profit contributions for components 1, 2, and 3 are $8, $6, and $9, respectively.

(a)

Formulate and solve for the recommended production quantities. If the constant is "1" it must be entered in the box. If an amount is zero, enter "0".

Let C1	= units of component 1 manufactured
C2	= units of component 2 manufactured
C3	= units of component 3 manufactured

Max	C1	+	C2	+	C3
s.t.
	C1	+	C2	+	C3	- Select your answer -≤≥=Item 7		Shaper
	C1	+	C2	+	C3	- Select your answer -≤≥=Item 12		Grinder
					C3	- Select your answer -≤≥=Item 15		Maximum units of component 3
	C1					- Select your answer -≤≥=Item 18		Maximum units of component 1
			C2			- Select your answer -≤≥=Item 21		Maximum units of component 2
	C1					- Select your answer -≤≥=Item 24		Minimum units of component 1
			C1, C2, C3			- Select your answer -≤≥=Item 26

Optimal solution: C1 =  , C2 =  , C3=

(b)
