Explanation / Answer

5. In a transshipment model, the flow-in of a supply node can be greater than itsflow-out ( )

Demand node

6. It is possible that the optimal solution of a transportation problem under a balanced supply-demand situation is same as that of its corresponding transportation problem under an unbalanced supply-demand situation. ( )

Yes,( by adding dummy )

7. A min-Max model problem has two types of decision variables: independent variables and derivative variables that rely on the independent ones ( )

True

8. The matrix-block based Excel analysis is good at handling large or complex LPproblems ( )

True

Because by the matrix-block based Excel analysis we can use many variables while in the graphical method, we can use only two variables.
