The Decision Variables in transportation problems are:
a. profits
b. costs
c. flows
d. capacities

The graphical representation of a network in an optimization problem can be an aid in the development of a spreadsheet model.
True or False

The transportation model is a special case of the minimum cost network flow model. (MCNFM).
True or False

In transportation problems, shipments between supply points or between demand points are possible.
True or False

The cost of an arc in a shortest path problem is equal to the distance of the arc.
True or False.

In an optimized shipping plan, most of the shipments occur on the low-cost routes, but this is not always the case.
True or False

A minimum cost network flow model (MCNFM) has the following advantages relative to the special case of a simple transportation model:
a. a MCNFM does not require capacity restrictions on the arcs of the network.
b. the flows in a general MCNFM don't necessarily have to be from supply locations to demand locations.
c. a MCNFM is Generally easier to formulate and solve.
d. all of these options

Problems which deal with the direct distribution of products from supply locations to demand locations are called:
a. transportation problems
b. assignment problems
c. network problems
d. transshipment problems.
