Question 4

The linear programming model of a transportation problem has one goal - the maximization of its objective function.

Question 5

In a transportation problem with three locations and two destinations, the objective function is as follows: Min 20X₁₁ + 18X₂₁ + 23 X₃₁ + 16X₁₂ + 14X₂₂ + 12X₃₂.How much does it cost to ship one unit from location 1 to destination 2?

A)18
B)12
C)23
D)16
E)14

Question 6

The transportation model assumes shipping cost per unit is the same regardless of the number of units shipped (there are no quantity discounts).

Question 7

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

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

Question 8

Which of the following is not information 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 above are necessary

Question 9

This model indicates that it costs ________ dollars to ship one unit from location(s) _______ to location(s) ___.

A)60; I; A, B & C
B)30; I, II & III; A
C)5; II; B
D)9; II; A
E)7; III; C

Question 10

The transportation method is a linear programming technique.Linearity is present in the following way:

A)The cost of goods shipped from any source to any destination is a linear function of quantity shipped.
B)The cost of goods shipped from any source to any destination is a linear function of the cost per unit.
C)The total cost associated with a given plan is a linear function of shipping costs.
D)Cell evaluations require linear horizontal movements through the matrix.
E)Cell evaluations are linear.

Question 11

Which of the following is an objective function for the problem?

A)
B)
C)
D)
E)None of the above.

Question 12

The transportation model is a special type of linear regression model.

Question 13

For a transportation model to be used, more than one location must be considered.

Question 14

The transportation model assumes similar, homogeneous goods.

Question 15

Which of the following is a constraint for the customer (campaign headquarters)?

A)2X₁₁ + 9X₂₁ + X₃₁ = 20
B)5X₁₂ + 3X₂₂ + 8X₃₂ = 70
C)X₁₁ + X₁₂ + X₁₃ = 50
D)X₁₂ + X₂₂ + X₃₂ = 70
E)all of the above

Question 16

In a transportation problem with three locations and two destinations, the objective function is as follows: Min 20X₁₁ + 18X₂₁ + 23 X₃₁ + 16X₁₂ + 14X₂₂ + 12X₃₂.How much does it cost to ship one unit from location 2 to destination 1?

A)18
B)12
C)23
D)16
E)None of the above.

Question 17

Which of the following is not an assumption of the transportation model?

A)Actual supply and demand must be equal.
B)Shipping costs per unit are constant per unit.
C)Items to be shipped are homogeneous.
D)There is only one transportation route between each source and destination.
E)There is only one transportation mode between each source and destination.

Question 18

Which of the following is a constraint for the suppliers (button producers)?

A)
B)
C)
D)
E)all of the above

Question 19

Which of the following is the information needed to use the transportation model?

A)A list of the sources and each one's capacity
B)A list of the destinations and each one's demand
C)The unit cost of shipping items from each source to each destination
D)All of the above
E)None of the above

Question 20

Dummy rows or columns to equate supply and demand are available but not required in linear programming models of transportation problems.
