Transportation Linear Programming:

How would a situation where the demand locations require more than is available at the supply locations be handled? How are the results interpreted?

When can a transportation problem be a maximization problem?

Give an example of a transportation problem that has a capacity limit of route minimum for one or more routes.

Are you allowed to look at a route and simply say, "my intuition rules out this route," or would a route be ruled out because a road is closed, or some other feature of the route deems the route unusable?
