Question

What is transportation problem ? Explain the method to solve by North-West corner method.

Answer 1

Steps in North West Corner Rule  

Select the upper left-hand corner cell of the transportation table and allocate as many units as possible equal to the minimum between available supply and demand, i.e., min(s1, d1).  

Adjust the supply and demand numbers in the respective rows and columns.  

If the demand for the first cell is satisfied, then move horizontally to the next cell in the second column.  

If the supply for the first row is exhausted, then move down to the first cell in the second row.  

If for any cell, supply equals demand, then the next allocation can be made in cell either in the next row or column.  

Continue the process until all supply and demand values are exhausted.
