Exam 7: Business Analytics With Shipment Models

In the transportation model, shadow prices are effective in the ranges defined by the allowable increase and allowable decrease values.

The constraints in a transportation model stipulate that:

The implementation of radio frequency identification technology allows decision makers to have instant access to:

In a network diagram, nodes can represent:

A transshipment problem with four layers may include:

Transshipment models cannot be formulated as linear programming models.

Transshipment models are usually less complicated than transportation models.

A zero value for the shadow price of a constraint indicates that the reduction or increase in the value of the right-hand-side value of that constraint will not impact the objective function.

When trying to enforce that a shipment cannot be sent from a certain source to a certain destination, the modeler can:

Which of the following is not an element of network diagrams used to represent shipment models?

In the transportation model, the reduced costs indicate:

A zero value for the shadow price of a constraint indicates that the constraint is binding.

Which of the following situations results in an infeasible transportation model?

If the problem is infeasible, then the modeler can create a dummy destination in order to equalize the demand and supply.

The objective function of the transportation model may seek to minimize the overall cost of transportation, which can be calculated as:
