After several iteration the solution obtained is shown below.

Factories	A	B	C	D	E	DUMMY	SUPPLY
W	17	9	14 15	10 30	14	0 20	75
X	10 13	6 20	11 15	11	12	0	45
Y	6 30	17	9	12	12	0	30
Z	15	20	11	14	6	0	50
Demand	40	20	50	30	40	20	200

(a) Is this an optimal solution? How do you know?

(b) Is there an alternate solution? if so find it.

(c) Suppose some new equipment was installed that reduces the variable operation cost by two birr per ton in factory X is the shipping schedule remain optimum? If you what is the new optimum?
