UNBALANCED TRANSPORTATION PROBLEM

Unbalanced transportation problem is a transportation problem where the total availability at the origins is not equal to the total requirements at the destinations. For example, in case the total production of 4 factories is 1000 units and total requirements of 4 warehouses is 900 units or 1,100 units, the transportation problem is said to be an unbalanced one. To make an unbalanced transportation problem, a balanced one, a dummy origin(s) or a dummy destination (s) (as the case may be) is introduced with zero transportation cost per unit.
