Solution
The assignment problem is a special case of the transportation problem.
The differences are given below:
| Transportation Problem | Assignment Problem |
| 1. This is about reducing the cost of transportation merchandise | 1. This is about assigning finite sources to finite destinations where only one destination is allotted for one source with a minimum cost |
| 2. Number of sources and number of demand need not be equal | 2. Number of sources and the number of destinations must be equal |
| 3. If total demand and total supply are not equal then the problem is said to be unbalanced. | 3. If the number of rows is not equal to the number of columns then problems are unbalanced. |
| 4. It requires 2 stages to solve: Getting initial basic feasible solution, by NWC, LCM, VAM and optimal solution by MODI method | 4. It has only one stage. Hungarian method is sufficient for obtaining an optimal solution |
