Question 1

The total amount paid to various carriers for transporting products to customers is

Accepted Answer

The total amount paid to various carriers for transporting products to customers is referred to as transportation cost. This cost includes expenses such as shipping fees, freight charges, and any other costs associated with getting the product from the warehouse to the customer's location.

Question 2

Which transportation network design option has the elimination of intermediate warehouses and its simplicity of operation and coordination as its major advantage?

Accepted Answer

The direct shipping network design option is the best choice as it eliminates the need for intermediate warehouses, which simplifies the coordination and operation of the transportation network. This results in a more efficient and cost-effective system.

Question 3

When infrastructure is publicly owned,it is important to price usage to reflect

Accepted Answer

Pricing usage of publicly owned infrastructure to reflect the marginal impact on the cost to society is important as it ensures that the cost of using the infrastructure is aligned with the benefit it provides to society. This approach takes into account not only the operating cost and incremental profit but also the externalities and social cost associated with the usage of the infrastructure. It encourages users to consider the full cost of their usage, leading to more efficient and sustainable use of the infrastructure.

Question 4

The most important operational decision related to transportation in a supply chain is

Accepted Answer

The routing and scheduling of deliveries is the most important operational decision related to transportation in a supply chain as it directly affects the delivery time to customers, inventory levels, and overall customer satisfaction. While minimizing transportation costs is important, it should not be the sole focus as it may compromise delivery efficiency and customer service. Maximizing profitability of the supply chain and reducing cycle inventory are also important operational decisions but are not specifically related to transportation.

Question 5

In almost all countries,roads,seaports,airports,rail and canals have this in common.

Accepted Answer

In almost all countries, roads, seaports, airports, rail, and canals are built and managed by the government, regardless of their location or tax revenue generation.

Question 6

At a train station where lines intersect,the Mumbai dabbawalas perform

Accepted Answer

The Mumbai dabbawalas perform a cross-dock function at train stations where lines intersect. They collect lunch boxes from various residential areas and then sort and transfer them at these stations to be sent to the appropriate destinations. Thus, the correct choice is D.

Question 7

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion,operation and maintenance.The total traffic t is used to determine the cost of 5t2.What is the average cost per motorist?

Accepted Answer

The total cost for all motorists is 5t^2. To find the average cost per motorist, we need to divide this total cost by the total number of motorists. We don't know the exact number of motorists, but we do know that the total traffic is t. Therefore, the average cost per motorist is:
(5t^2)/t = 5t
So the answer is choice C.

Question 8

The Mumbai dabbawalas have a transportation network that at the beginning of each day is best described as

Accepted Answer

The Mumbai dabbawalas use a milk run system, where a single transportation route collects and delivers items to multiple locations, optimizing efficiency and reducing costs. This system allows them to efficiently collect tiffins from homes and deliver them to the respective workplaces.

Question 9

Which of these statements about use fees for a highway is best?

Accepted Answer

A flat rate simplifies the cost of using the highway, making it more predictable and potentially more accessible for most individuals, which can lead to higher use. Variable fees, such as those based on congestion, can deter use during peak times due to higher costs.

Question 10

The Mumbai dabbawalas have a transportation network that takes advantage of

Accepted Answer

The Mumbai dabbawalas use a transportation network that takes advantage of both low uncertainty and temporal aggregation of demand and also use of transportation resources while they are underutilized. They have a system in place that ensures that lunch boxes are picked up and delivered at specific times, with little uncertainty in demand. They also take advantage of underutilized transportation resources, such as trains and bicycles, and use them to deliver lunch boxes.

Question 11

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion,operation and maintenance.The total traffic t is used to determine the cost of 5t2 + 7t.What is the marginal cost?

Accepted Answer

To find the marginal cost, we need to take the derivative of the cost function with respect to traffic t:

C(t) = 5t^2 + 7t
C'(t) = 10t + 7

Therefore, the marginal cost is 10t + 7. The correct choice is D.

Question 12

Which transportation network design is pictured?

Accepted Answer

The answer of Which transportation network design is pictured? 
...

Question 13

Which transportation network design option establishes an extra layer between suppliers and retailers to store inventory and to serve as a transfer location?

Accepted Answer

The option of shipping all products via a central distribution center would establish an extra layer between suppliers and retailers, as the products would be stored in the central DC before being distributed to the retail locations. This would provide an opportunity for inventory to be maintained at the DC and allow for more efficient transfer of products to the retailers. The other options do not establish an extra layer between suppliers and retailers, as they involve direct shipping from suppliers to retailers without any intermediary storage or transfer locations.

Question 14

The Mumbai dabbawalas deliver

Accepted Answer

The Mumbai dabbawalas are known for delivering home-cooked lunches to office workers in the city. They collect the lunch boxes from the homes of the workers and deliver them to their workplaces, and then return the empty boxes back to the homes in the afternoon.

Question 15

Which transportation network design option uses a combination of milk runs,shipping via DC,shipping via intermediate DC with storage,and direct shipping with milk runs to reduce the cost and improve responsiveness of the supply chain?

Accepted Answer

The tailored network design option combines different methods of transportation to optimize cost and responsiveness. This option takes into account the specific needs and constraints of the supply chain and designs a customized transportation network. Therefore, the tailored network is the most appropriate option for improving the overall supply chain performance.

Question 16

Cheaper modes of transport typically have

Accepted Answer

Cheaper modes of transport, such as sea or rail, often have longer lead times due to slower speeds and may require larger minimum shipment quantities to be cost-effective, compared to more expensive, faster options like air freight.

Question 17

Which transportation network design is pictured?

Accepted Answer

The answer of Which transportation network design is pictured? 
...

Question 18

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion,operation and maintenance.The total traffic t is used to determine the cost of 5t2 + 7t.What is the average cost per motorist?

Accepted Answer

The average cost per motorist is found by dividing the total cost by the total number of motorists (t), which gives (5t^2 + 7t) / t = 5t + 7.

Question 19

The Mumbai dabbawalas perform

Accepted Answer

The Mumbai dabbawalas perform both a forward logistics function by delivering lunch boxes from homes to workplaces and a reverse logistics function by collecting the empty lunch boxes from workplaces and returning them to the respective homes.

Question 20

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion,operation and maintenance.The total traffic t is used to determine the cost of 5t2.What is the marginal cost?

Accepted Answer

To find the marginal cost, we need to take the derivative of the cost function with respect to traffic t.

Cost function = 5t^2

Marginal cost = d(Cost)/d(t) = 10t

Therefore, the correct answer is D, 10t.
