Unbalanced Assignment Problems
Often the number of people or objects to be assigned does not equal the number of tasks or clients or machines listed in the columns, and the problem is unbalanced
When this occurs, and there are more rows than columns, simply add a dummy columnor task
If the number of tasks exceeds the number of people available, we add a dummy row
Since the dummy task or person is nonexistent, we enter zeros in its row or column as the cost or time estimate
