Question

Harrington Corporation produces three products, A, B, and C. Pertinent information on these products is as follows:

There are 150 direct labor hours available. Machine-hour capacity allows 100 anchor bolts, only; 50 bearings, only; 40 casters, only; or any combination of the three that does not exceed the capacity.

The direct labor hour constraint for Harrington's linear programming model is:

A + B + C 150.

Min Z = 2A + 2B + 3C.

Max Z = 2A + 2B + 3C - 150.

100A + 50B + 40C 1,050.

2A + 2B + 3C 150.

Product Selling Price
per Unit Variable Cost
per Unit Fixed
Cost per Unit DL Hours
per Unit A (Anchor bolts) $4.00 $1.00 $2.00 2 B (Bearings) $3.50 $0.50 $2.00 2 C (Castings) $6.00 $2.00 $3.00 3

Explanation / Answer

Here we need direct labor hour constraint for Harrington's linear programming model

Direct labour hours per unit

A=2

B=2

C=3

So total hours available is 150

direct labor hour constraint for Harrington's linear programming model

2A + 2B + 3C 150.

=
