Set up the transportation problem for each situation independently.

A- Each warehouse has a supply of 26 and each customer has a demand of 13. Demand must be satisfied. The objective is to minimize total shipping cost.

B- All demands are 23 and all supplies are 56. All demands must be met, but not all supplies must be shipped. The objective is to minimize total shipping cost.B-

C- All demands are 23 and all supplies are 36. All demands need not be met but ship as much as possible. The objective is to minimize total shipping cost.

D- All demands are 28 and all supplies are 46. All demands need not be met but each customer must receive at least 5 units. Ship as much as possible. The objective is to minimize total shipping cost.

First we set up the LP for the problem:

The boxes in green, are decision variables
The boxes in blue are constrains
The boxes in orange is the objective function

The formulae used:

Customer 1 Customer 2 Customer 3 Customer 4
Warehouse A 8 8 11 5
Warehouse B 10 7 15 7
Dec Var How much to send from each WH to each customer Customer 1 Customer 2 Customer 3 Customer 4
Warehouse A 7 0 13 6 =SUM(C7:F7) <= 26
Warehouse B 6 13 0 7 =SUM(C8:F8) <= 26
=SUM(C7:C8) =SUM(D7:D8) =SUM(E7:E8) =SUM(F7:F8)
>= >= >= >=
13 13 13 13
Objective function
Total shipping cost =SUMPRODUCT(C3:F4,C7:F8)
