Solving Transportation Problem with Minimum Cost Method and Northwest Corner Method Minimum Cost and Northwest Corner Methods are effective way to solve transportation problems but they can't find optimal solution always. Minimum Cost Method Find the decision variable with smallest shipping cost Assign X ij its largest possible value (which is the min of S ij and D ij ) Cross out the row or column, then continue with the next minimum cost Northwest Cornet Method 1.Select the upper left (north-west) cell of the transportation tableau, allocate the maximum amount allowable by the supply and demand to variable X 11 2 If a column (or row) is satisfied, cross it out. The remaining decision variables in that column (or row) are set to zero. If a row and column are satisfied simultaneously, cross only one out (it does not matter which) 3 Adjust supply and demand for the non-crossed rows and columns. Alloc...
