Electrocomp's management realizes that it forgot to

include two critical constraints (see Problem 7-14). In

particular, management decides that there should be a

minimum number of air conditioners produced in

order to fulfill a contract. Also, due to an oversupply of fans in the preceding period, a limit should be

placed on the total number of fans produced.

(a) If Electrocomp decides that at least 20 air conditioners

should be produced but no more than 80

fans should be produced, what would be the optimal

solution? How much slack is there for each

of the four constraints?

(b) If Electrocomp decides that at least 30 air conditioners

should be produced but no more than

50 fans should be produced, what would be

the optimal solution? How much slack is there

for each of the four constraints at the optimal

solution?
