The table for transportation problem involves m rows and n columns. We use Oi as the heading for row i to indicate that this row pertains to the origin i. Similarly, we use Dj as a heading for the columns j to indicate that this column pertains to destination j. The mn squares formed by these m rows and n columns are called cells. The per unit cost Cij of the transporting from the ith origin to the jth destination is shown in the lower right side of the (i, j)th cell. Any feasible solution xij is shown encircled inside the (i, j)th cell. The availabilities ai are shown as a column on the right-hand side of mn cells, while the requirements bj have been shown as a row below the mn cells. The ai and bj are called ...
