1. The transportation model assumes similar, homogeneous goods.
2. The transportation model assumes shipping cost per unit is the same regardless of the
number of units shipped (there are no quantity discounts).
3. The transportation model is a special type of linear regression model.

4. For a transportation model to be used, more than one location must be considered.
5. The linear programming model of a transportation problem has one goal – the maximization
of its objective function.
6. Dummy rows or columns to equate supply and demand are available but not required in
linear programming models of transportation problems.

17. In a transportation problem with three locations and two destinations, the objective
function is as follows: Min 20X11 + 18X21 + 23 X31 + 16X12 + 14X22 + 12X32. How much
does it cost to ship one unit from location 2 to destination 1?
