TRANSPORTATION, TRANSSHIPMENT AND ASSIGNMENT PROBLEMS
TRUE/FALSE
1.0
In a transportation problem, items are allocated from sources to destinations at a maximum cost.
False
2.0
The linear programming model for a transportation problem has constraints for supply at each
source and demand at each destination.
True
3.0
In a balanced transportation model where supply equals demand, all constraints are equalities.
True
4.0
The transshipment model is an extension of the transportation model in which intermediate
transshipment points are added between the sources and destinations.
True
5.0
In a transshipment problem, items may be transported from one transshipment point to another.
True
6.0
An assignment problem is a special form of transportation problem where all supply and demand
values equal 0.
False
7.0
An example of a __________
point is a distribution center or warehouse located between plants
and stores.
Transshipment
8.0

for
each node.
Constraint
9.0
A plant has 4 jobs to be assigned to 4 machines; each machine has different manufacturing times
for each product. The production manager wants to determine the optimal assignments of 4 jobs
to 4 machines to minimize total manufacturing time. This problem can be most efficiently solved
using the _____________
