This is one of the most efficient methods as it determines the optimal solution quickly and requires less calculation. This is used to calculate the basic feasible solution of a transportation problem by considering the lowest cost in the matrix. The Steps of LCM are as follows:

1. Identify the lowest cost cell in the entire transportation matrix and allocate units as much as possible to this cell.

2. Eliminate the row or column in which either supply or demand is exhausted. In case the lowest cost cell is not unique, select the cell where maximum allocation can be made.

3. After adjusting the supply and demand for all uncrossed rows and columns, repeat the procedure with the next lowest unit cost among the remaining rows and columns of the transportation matrix.


4. Repeat the procedure until the entire supply at different sources is exhausted to satisfy the demand at different warehouses.
