1. Consider the transportation table below. The solution displayed was obtained by performing some iterations of the transportation method on this problem. Source 1 Destination 2 $301 3 $301 A 30 5 Capacity $5 35 $100 10 $10 $100 B 10 $20 $10 $25 C 50 15 35 Demand 30 25 40 The total cost of the current solution provided = dollars. Using stepping stone method, to perform an improvement iteration, the improvement index for the unused cell will be: A-2 = B-1 = B-3= C-1 = Based on the improvement index for each of the unused cells, in the first improvement iteration, unused cell B-1 should get an assignment of units a) The improved transportation flow will be: From (Note: You must enter a shipment in every cell, even if the shipment is 0. To 1 2 Capacity $30 $30 $5 35 IA $10 $10 $10 B 10 $20 $10 $25 C 50 b) The total cost of the improved solution = dollars. 2. The three blood banks in Seminole County, Florida, are coordinated through a central office that facilitates blood delivery to four hospitals in the region. The cost to ship a standard container of blood from ea hospital is shown in the table below. Also given are the biweekly number of containers available at each bank and the biweekly number of containers of blood needed at each hospital Source Hospital 1 Destination Hospital 2 Hospital 3 $9 $11 Supply Hospital 4 $16 $8 Bank 1 50 $12 $7 $5 $8 Bank 2 80 $14 $10 $6 $1 Bank 3 120 Demand 90 70 40 50 The given transportation problem is (1) The number of shipments should be made biweekly from each blood bank to each hospital so that total shipment costs are minimized: (Note: You must enter a shipment in every cell, even if the shipment is 0.)
