QUESTION 31 Answer the following two questions based on the transshipment network given below. Observe that nodes 1, 2, and 3 are supply nodes, 4 and 5 are transshipment nodes and finally, 6 and 7 are demand nodes. Numbers on the arcs represent the cost of shipping one unit along the arc. Decision variables are defined as follows: Xij- the amount shipped from node i to nodej. 500 3 1 6 )-600 4 9 400 2 6 12 2 IS 8 7 H-600 300( 3 10 Assume that you formulate this transshipment problem as an LP.
