Question 18

A firm has established a distribution network for the supply of a raw material critical to its manufacturing.Currently there are two origins for this raw material,which must be shipped to three manufacturing plants.The current network has the following characteristics:   The firm has identified two potential sites for a third raw material source; these are identified as Candidate A and Candidate B.From A,the costs to ship would be $9 to Plant 1,$10 to Plant 2,and $12 to Plant 3,respectively.From B,these costs would be $11,$14,and $8,respectively.The new source,wherever it is located,will have a capacity of 500 units.Set up this problem as two separate transportation matrices.(Do not solve the problem.)
