Chapter 8 problems:
•
Problem 11
a.
No change in optimal solution, there is no upper limit for the range of
optimality for the objective coefficient for S.
b.
No change in the optimal solution, the objective coefficient for M can
increase to 6.4.
c.
The optimal solution does not change
•
Problem 17
a.
Produce 1000 units of model DRB and 800 units of model DRW.
Total profit contribution $424,000
b.
The dual value for constraint one is 8.80. Each additional pound of
steel will increase profit by $8.80. At $2 per pound Deegan should
purchase the additional 500 pounds. The upper limit on the right hand
side range for constraint 1 is approximately 40,909, the dual value of
$8.80 is applicable for an increase of as much as 909 pounds.
c.
Constraint three has a slack of 4000 hours. Increasing the number of
assembly time is not worthwhile.
d.
The objective coefficient range for model DRB shows a lower limit of
$112. The optimal solution will not change, the value of the optimal
solution will be $175(1000) + $280(800) = $399,000
