Question

When total supply is less than total demand, there is no feasible LP O a dummy origin is added with a supply that equals the sum of total demand and total supply and zero cost assigned to each arc leaving the dummy origin O a dummy origin is added with a supply that equals the difference between total demand and total supply and zero cost assigned to each aro leaving the ation model solution. However, a feasible solution can occur when dummy origin O a dummy origin is added with a supply that equals the difference between average demand and average supply arl zero cost assigned to each arc leaving O none of the above the dummy origin

Explanation / Answer

If the total supply is less than total demand then the lp transportation model would not have a feasible soulution. This can be fixed by adding a dummy origin to the supply with supply equal to the difference between the total demand and total supply. As the dummy demand points are not real, the cost assigned will be zero.

Hence the correct option is b. Dummy origin is added with supply that equals the difference between the total demand and total supply ......
