(a) OBJECTIVE FUNCTION : MINIMIZE COST = XijCij : i,j=1 to m,n
SUBJECT TO (CONSTRAINTS) : Xij =Sij for all i=1 to m
Xij =Dij for all i=1 to n
Xij > 0
Xij represent number of items shipped from warehouse i to distribution j
Cij represent cost
(b) From the solution, we can already see that distributor E,F and H are serviced by only one distributor each.
For F , we have to find which warehouse results in least cost. So, we will minimize cost of F alone subject to supply and demand constraints as written above.
Minimum requirement for F is 25 out of which it takes 15 from A and 5 from B and C each. Now that it can only take from one, trying out combinations of each warehouse supplying to F in excel, we see the following results:
In first and third image i.e supply done by A and C respectively, we see the supply constraint is not satisfied in each case
( NOTICE CELL H22 IS 70 WHICH EXCEEDS CONSTRAINT OF 50 in picture 3 of (b) AND CELL H20 IS 60 WHICH ALSO EXCEEDS SUPPLY CONSTRAINT OF 50 in picture 3 of (b))
This leaving us with only B supplying to F. Total cost is 635 which is (635-590=45) . Cost exceeds by 45 due to this rule.
(c) Distribution cost is inflated by( in %) = (NEW-OLD)/OLD *100 = ((635-590)/590)*100 =7.62 %
