• Feasible solution:when non negative values of x_ij where i= 1 , 2 , …m and j= 1 , 2 , …n satisfy the constraints of availability or supply and demand or requirement is called the feasible solution of the transportation problem.
• Basic feasible solution: it is that feasible solution that contains only m + n -1 non-negative distribution.
• Optimal solution: when the transportation cost is minimum then the feasible solution is said to be the optimal solution.
• Balanced transportation problem: a transportation problem in which the total supply from all the sources equals the total demand in all the destinations.

Mathematically, _i=1 ʃ^m a_i = _j=1ʃⁿ b_i

• Unbalanced transportation problem: such problems which are not balanced are called unbalanced.

Mathematically,   _i=1ʃ^m a_{i ≠ j=1}ʃⁿ b_i

• Matrix terminology: transportation problem is also solved by the matrix system. As we all know in matrix the vertical cells are called columns and horizontal cells as rows.
