Which of the following phrases can not be said about the Transportation Model?


A transportation problem is a linear optimization problem, which seeks to minimize the total costs of shipment of items from certain origins to a number of destinations while fulfilling the requirements of destinations and emptying the origins.

Some transportation problems may be less restrictive; the total supply may exceed aggregate demand.

This model has the origin locations from where a single unit can be transported to a dedicated destination, and vice versa—the model has the destinations to which a single unit is sent solely from one origin location.

The decision variables of this problem are the amounts to be shipped for each origin-destination pairs.

A transportation problem has a feasible solution only if the total availability meets all the requirements.


4.Soru

What is the difference between balanced transportation model and an unbalanced one?


Maximum value of the upper limits for the decision variables

The number of degenerate variables in the optimum solution

The equality between the total supply and total demand

The requirement of a basis to test the optimality

Derivability of its dual model

Which of the following is not one of the steps that the transportation model has taken to reach a solution?


Identify the smallest value of each row for the cost matrix of the assignment problem.

Determine a basic feasible solution to initiate

Iterate to the next basic feasible solution by determining the entering and leaving variable using the rate of improvement on the objective value.
