Develop a binary integer model that will determine the two containers that will maximize the value of the shipment.
What will be an ideal response?
Let C1 = if Container 1 is considered for shipment; 0 otherwise
C2 = if Container 2 is considered for shipment; 0 otherwise
C3 = if Container 3 is considered for shipment; 0 otherwise
C4 = if Container 4 is considered for shipment; 0 otherwise
C2 = if Container 2 is considered for shipment; 0 otherwise
C3 = if Container 3 is considered for shipment; 0 otherwise
C4 = if Container 4 is considered for shipment; 0 otherwise
