Question 1

Upon completion of the northwest-corner rule,which source-destination cell is guaranteed to be occupied?
A)top-left
B)top-right
C)bottom-left
D)bottom-right
E)the cell with the lowest shipping cost (or at least one of them if there's a tie)

Accepted Answer

The northwest-corner rule always starts with the top-left cell, so it is guaranteed to be occupied.

Question 2

A firm has established a distribution network for the supply of a raw material critical to its manufacturing.Currently there are two origins for this raw material,which must be shipped to three manufacturing plants.The current network has the following characteristics:  The firm has identified two potential sites for a third raw material source;these are identified as Candidate A and Candidate B.From A,the costs to ship would be $9 to Plant 1,$10 to Plant 2,and $12 to Plant 3,respectively.From B,these costs would be $11,$14,and $8,respectively.The new source,wherever it is located,will have a capacity of 500 units.Set up this problem as two separate transportation matrices.(Do not solve the problem. )

Accepted Answer

The setup requires two transportation problems,each with three sources.

Question 3

The northwest-corner rule is best used:
A)to minimize the total shipping cost from several origins to several destinations.
B)to calculate whether a feasible solution is also an optimal solution.
C)to calculate how much to transfer from one shipping route to another.
D)to generate an initial feasible solution to a transportation problem.
E)to resolve cases of degeneracy in transportation problems.

Accepted Answer

The northwest-corner rule is a method for generating an initial feasible solution to a transportation problem. It involves filling in the cells of the transportation tableau starting from the upper-left corner (northwest corner) and moving diagonally down the table until all supply and demand values are satisfied.

Question 4

The purpose of the transportation approach for location analysis is to minimize which of the following?
A)total costs
B)total variable costs
C)total fixed costs
D)total shipping costs
E)the number of shipments

Accepted Answer

The purpose of the transportation approach for location analysis is to minimize total shipping costs. This approach involves determining the best location for a facility based on how it will affect transportation costs for shipping goods to customers or other facilities. The transportation approach considers factors such as shipping distances, transportation modes, and shipping rates to minimize these costs.

Question 5

The transportation model is an excellent tool for minimizing shipping costs among existing facilities,but it is not useful when firms consider new facility locations.

Accepted Answer

The transportation model can also help in the selection of new facility locations by analyzing shipping costs from potential locations to existing facilities and demand points. It can also consider different modes of transportation and their associated costs.

Question 6

The initial solution to a transportation problem can be generated several ways,so long as:
A)it minimizes cost.
B)it ignores cost.
C)all supply and demand conditions are satisfied.
D)degeneracy does not exist.
E)all cells are filled.

Accepted Answer

The initial solution to a transportation problem must satisfy all supply and demand conditions to ensure that all goods are being transported and no shortages or excesses occur. Minimizing cost is a goal but it is not the requirement for the initial solution. Degeneracy is a phenomenon that may occur in transportation problems when there are more than one optimal solution. Filling all cells is important but not the only requirement. Therefore, the best choice is C.

Question 7

For the problem data set below,what is the northwest-corner allocation to the cell Source 1-Destination 1? 
A)0
B)2

D)90
E)30

Question 8

Which of the following is NOT information needed for a transportation problem?
A)the cost of shipping one unit from each origin to each destination
B)the set of destinations and the demand at each
C)the set of origins and the demand at each origin
D)the list of sources and the capacity at each
E)None of the above is needed.

Question 10

The transportation method is a special case of the family of problems known as what?
A)regression problems
B)decision tree problems
C)linear programming problems
D)simulation problems
E)statistical problems

Accepted Answer

The transportation method, also known as the transportation problem, is a type of linear programming problem. Linear programming is a mathematical optimization technique used to find the best possible outcome in a given mathematical model. Therefore, the correct answer is option C, linear programming problems.

Question 11

Which of the following is NOT needed in order to use the transportation model?
A)the source points and their capacity
B)the fixed costs of source points
C)the destination points and their demand
D)the cost of shipping one unit from each source to each destination
E)All of these are needed.

Accepted Answer

Fixed costs of source points are not needed in order to use the transportation model. The model only requires information about the source points' capacity, destination points and their demand, and the cost of shipping one unit from each source to each destination.

Question 12

Question 14

A feasible solution in transportation models is one in which all of the supply and demand constraints are satisfied.

Accepted Answer

A feasible solution means that all constraints are satisfied, in this case, the supply and demand constraints.

Question 15

A transportation problem requires exactly as many origins as destinations.

Accepted Answer

A transportation problem can have more origins than destinations or vice versa. In such cases, dummy origins or destinations can be introduced to balance the problem.

Question 16

Neither the northwest-corner rule nor the intuitive method considers shipping cost in making initial allocations.

Accepted Answer

The northwest-corner rule does not consider shipping costs, but the intuitive method does take into account the shipping costs to make initial allocations more cost-effective.

Question 17

The transportation model seeks satisfactory,but not necessarily optimal,solutions for shipping goods from several origins to several destinations.

Accepted Answer

The transportation model seeks to find the most cost-effective way to ship goods from several origins to several destinations, aiming for an optimal solution rather than just a satisfactory one.

Question 18

The transportation model is a special class of linear programming models.

Accepted Answer

This statement is true. The transportation model is a linear programming model that is used to determine the optimal transportation plan for goods and products from multiple sources to multiple destinations, while minimizing transportation costs.
