B)equate (balance)total cost of shipping to each of them to the total cost of shipping output from them.
C)ensure total input to all of them is less than the total supply available.
D)ensure total input to all of them is sufficient for the total demand of destinations.
E)balance shipments so that each transshipment point receives and ships an equal quantity.
