Question 5

The transportation model assumes one mode of transport between each origin and destination.

Question 6

A campaign manager for a political candidate must arrange the shipment of 150 cartons of campaign buttons from three button producers to three campaign headquarters.The supplies and demands,and the per-carton transportation costs,are shown below:
Which of the following is an objective function for the problem?

A) Min 50X11 + 50X12 + 50X13 + 20X31 + 70X32 + 60X33
B) Min 2X11 + 5X12 + 6X13 + 9X21 + 3X22 + 7X23 + X31 + 8X32 + 4X33
C) Max 2X11 + 5X12 + 6X13 + 9X21 + 3X22 + 7X23 + X31 + 8X32 + 4X33
D) Max 20X11 + 70X12 + 60X13 + 50X31 + 50X32 + 50X33
E) None of the choices are correct.

Question 7

The decision variables for a transportation model are the quantities to be shipped.

Question 8

The transportation model assumes transportation cost per unit is the same regardless of the number of units shipped.

Question 9

The transportation model assumes homogeneous goods.

Question 10

Which of the following information is not needed to use the transportation model?

A) Capacity of the sources
B) Demand of the destinations
C) Unit shipping costs
D) Unit shipping distances
E) All of the choices.

Question 11

To formulate a transshipment problem as a linear program similar to the transportation problem,transshipment points must:

A) equate the total input into each of them to the total output from them.
B) equate (balance) total cost of shipping to each of them to the total cost of shipping output from them.
C) ensure total input to all of them is less than the total supply available.
D) ensure total input to all of them is sufficient for the total demand of destinations.
E) balance shipments so that each transshipment point receives and ships an equal quantity.

Question 12

Which of the following is the information needed to use the transportation model?
I)A list of the origins and each one's capacity per period.
II)A list of the destinations and each one's demand per period.
III)The unit cost of shipping items from each origin to each destination.

A) I only
B) II only
C) III only
D) II and III only
E) I, II, and III

Question 13

Which of the following are assumptions or requirements of the transportation method?
I)Goods are the same,regardless of the source.
II)There must be multiple sources.
III)Minimum quantities must be shipped.
IV)Shipping costs per unit do not vary with the quantity shipped.

A) I and IV only
B) II and III only
C) I, II, and IV only
D) I and III only
E) I, II, III, and IV

Question 14

An automobile manufacturer who has eight assembly plants and thousands of dealers throughout Canada can find the optimal distribution plan by using:

A) linear programming model.
B) transportation model.
C) location model.
D) linear programming model and transportation model.
E) all of the choices are correct.

Question 15

The transportation model method for evaluating location alternatives minimizes:

A) the number of sources.
B) the number of destinations.
C) the number of alternatives.
D) the total demand.
E) the total shipping cost.

Question 16

The transportation model can be used for capacity planning.
