A linear programming computer package is needed.

Frandec Company manufactures, assembles, and rebuilds material-handling equipment used in warehouses and distribution centers. One product, called a Liftmaster, is assembled from four components: a frame, a motor, two supports, and a metal strap. Frandec's production schedule calls for 5,500 Liftmasters to be made next month. Frandec purchases the motors from an outside supplier, but the frames, supports, and straps may be either manufactured by the company or purchased from an outside supplier. Manufacturing and purchase costs per unit are shown.

Component	Manufacturing Cost	Purchase Cost
Frame	$39.00	$52.00
Support	$12.50	$16.00
Strap	$7.50	$8.50

Three departments are involved in the production of these components. The time (in minutes per unit) required to process each component in each department and the available capacity (in hours) for the three departments are as follows.

Component	Department
Cutting	Milling	Shaping
Frame	3.5	2.2	3.1
Support	1.3	1.7	2.6
Strap	0.8		1.7
Capacity (hours)	350	420	680

(a)Formulate and solve a linear programming model for this make-or-buy application. (Let FM = number of frames manufactured, FP = number of frames purchased, SM = number of supports manufactured, SP = number of supports purchased, TM = number of straps manufactured, and TP = number of straps purchased. Express time in minutes per unit.)

Min ___?_

Cutting constraint ___?___

Milling constraint _____?___

Shaping constraint ______?__

Frame constraint _____?_____

Support constraint _____?___

Strap constraint _____?____

FM, FP, SM, SP, TM, TP 0

How many of each component should be manufactured and how many should be purchased? (Round your answers to the nearest whole number.)

(FM, FP, SM, SP, TM, TP) = (_?__,___?__)

(b)What is the total cost (in $) of the manufacturing and purchasing plan?

$ ___?___

(c)How many hours of production time are used in each department? (Round your answers to two decimal places.)

Cutting ____?___ hrs

Milling ____?____ hrs

Shaping ____?____ hrs

(d) How much (in $) should Frandec be willing to pay for an additional hour of time in the shaping department?

$ _____?____

(e)Another manufacturer has offered to sell frames to Frandec for $45 each. Could Frandec improve its position by pursuing this opportunity? Why or why not? (Round your answer to three decimal places.)

---Select--- Yes /No. The reduced cost of ___?___ indicates that the solution ---Select--- can /cannot be improved
