Question
The following LP formulation represents a transportation problem where raw material (in tons) is transported from Supplier i, i={1,2,3) to
Plant j, j={1,2,3). The problem is solved and the optimal objective function value is 5200. Using the sensitivity report shown below, what
would be the optimal total cost if the cost of transporting 1 ton from Supplier 2 to Plant 3 becomes 5?
Min Total cost = 1x11 + 3x12 + 5x13+3.5x21 +4x22+4.8x23 +3.5x31+3.6x32 +3.2x33
Subject to
x31+x32+x33 <= 500
x11+x21+x31 = 500
x12+x22+x32= 700
x13+x23+x33 = 600
xij<=200, for i= {2,3}
&j= {1, 2, 3)
xij >= 0, for i= {(1,2,3)
