In a transportation network, what is the Nash equilibrium?

  1. A state where no individual driver has an incentive to change their route.

  2. A state where all drivers are using the same route.

  3. A state where the total travel time is minimized.

  4. A state where the total cost of transportation is minimized.

Show answer
Correct Option: A
Explanation:

The Nash equilibrium is a state in which no individual driver can improve their own situation by changing their route, given the choices of the other drivers.

In a logistics network, what is the prisoner's dilemma?

  1. A situation where two or more players have conflicting interests and each player's best strategy depends on the strategy of the other players.

  2. A situation where two or more players have common interests and each player's best strategy is to cooperate with the other players.

  3. A situation where two or more players have no conflicting interests and each player's best strategy is to act independently of the other players.

  4. A situation where two or more players have no common interests and each player's best strategy is to act against the other players.

Show answer
Correct Option: A
Explanation:

The prisoner's dilemma is a situation in which two or more players have conflicting interests and each player's best strategy depends on the strategy of the other players. In a logistics network, this could occur when two or more companies are competing for the same customers or resources.

In a transportation network, what is the tragedy of the commons?

  1. A situation where a shared resource is overused and depleted because each individual user has an incentive to use the resource as much as possible.

  2. A situation where a shared resource is underused because each individual user has an incentive to conserve the resource.

  3. A situation where a shared resource is used efficiently because each individual user has an incentive to cooperate with the other users.

  4. A situation where a shared resource is used inefficiently because each individual user has an incentive to act against the other users.

Show answer
Correct Option: A
Explanation:

The tragedy of the commons is a situation where a shared resource is overused and depleted because each individual user has an incentive to use the resource as much as possible. In a transportation network, this could occur when drivers all use the same route, leading to congestion and delays.

In a logistics network, what is the coordination game?

  1. A game where two or more players have common interests and each player's best strategy is to cooperate with the other players.

  2. A game where two or more players have conflicting interests and each player's best strategy depends on the strategy of the other players.

  3. A game where two or more players have no conflicting interests and each player's best strategy is to act independently of the other players.

  4. A game where two or more players have no common interests and each player's best strategy is to act against the other players.

Show answer
Correct Option: A
Explanation:

The coordination game is a game where two or more players have common interests and each player's best strategy is to cooperate with the other players. In a logistics network, this could occur when two or more companies cooperate to share resources or to reduce costs.

In a transportation network, what is the Braess's paradox?

  1. A paradox where adding a new road to a network can actually increase the travel time for some drivers.

  2. A paradox where adding a new road to a network can actually decrease the travel time for all drivers.

  3. A paradox where adding a new road to a network can actually have no effect on the travel time for any drivers.

  4. A paradox where adding a new road to a network can actually increase the travel time for all drivers.

Show answer
Correct Option: A
Explanation:

Braess's paradox is a paradox where adding a new road to a network can actually increase the travel time for some drivers. This can occur when the new road creates a new route that is shorter than the existing routes, but also more congested.

In a logistics network, what is the Stackelberg game?

  1. A game where one player moves first and the other player moves second, and the first player's strategy affects the second player's payoff.

  2. A game where both players move simultaneously and each player's payoff depends on the strategy of the other player.

  3. A game where both players move sequentially and each player's payoff depends on the strategy of the other player.

  4. A game where both players move simultaneously and each player's payoff does not depend on the strategy of the other player.

Show answer
Correct Option: A
Explanation:

The Stackelberg game is a game where one player moves first and the other player moves second, and the first player's strategy affects the second player's payoff. In a logistics network, this could occur when one company makes a decision about its pricing or production strategy before the other companies make their decisions.

In a transportation network, what is the Wardrop equilibrium?

  1. A state where no individual driver has an incentive to change their route.

  2. A state where all drivers are using the same route.

  3. A state where the total travel time is minimized.

  4. A state where the total cost of transportation is minimized.

Show answer
Correct Option: A
Explanation:

The Wardrop equilibrium is a state where no individual driver has an incentive to change their route, given the choices of the other drivers. This is a refinement of the Nash equilibrium that takes into account the fact that drivers may have different preferences for different routes.

In a logistics network, what is the Bertrand game?

  1. A game where two or more players compete on price and each player's profit depends on the price of the other player.

  2. A game where two or more players compete on quantity and each player's profit depends on the quantity of the other player.

  3. A game where two or more players compete on quality and each player's profit depends on the quality of the other player.

  4. A game where two or more players compete on service and each player's profit depends on the service of the other player.

Show answer
Correct Option: A
Explanation:

The Bertrand game is a game where two or more players compete on price and each player's profit depends on the price of the other player. In a logistics network, this could occur when two or more companies compete for the same customers or resources.

In a transportation network, what is the Pigouvian tax?

  1. A tax that is imposed on drivers to discourage them from using congested roads.

  2. A tax that is imposed on drivers to encourage them to use congested roads.

  3. A tax that is imposed on drivers to discourage them from using uncongested roads.

  4. A tax that is imposed on drivers to encourage them to use uncongested roads.

Show answer
Correct Option: A
Explanation:

The Pigouvian tax is a tax that is imposed on drivers to discourage them from using congested roads. This tax is designed to internalize the negative externalities that drivers impose on other drivers by using congested roads.

In a logistics network, what is the Cournot game?

  1. A game where two or more players compete on quantity and each player's profit depends on the quantity of the other player.

  2. A game where two or more players compete on price and each player's profit depends on the price of the other player.

  3. A game where two or more players compete on quality and each player's profit depends on the quality of the other player.

  4. A game where two or more players compete on service and each player's profit depends on the service of the other player.

Show answer
Correct Option: A
Explanation:

The Cournot game is a game where two or more players compete on quantity and each player's profit depends on the quantity of the other player. In a logistics network, this could occur when two or more companies compete for the same customers or resources.

In a transportation network, what is the Hotelling model?

  1. A model that describes the location of firms along a linear market.

  2. A model that describes the location of firms in a two-dimensional space.

  3. A model that describes the location of firms in a three-dimensional space.

  4. A model that describes the location of firms in a four-dimensional space.

Correct Option: A
Explanation:

The newsvendor model is a model that describes the optimal quantity of inventory to hold in a warehouse. This model is used to balance the costs of holding inventory with the costs of running out of inventory.

In a transportation network, what is the gravity model?

  1. A model that describes the flow of traffic between two points.

  2. A model that describes the flow of traffic between multiple points.

  3. A model that describes the flow of traffic between all points in a network.

  4. A model that describes the flow of traffic between all points in a network, taking into account the cost of travel.

Show answer
Correct Option: A
Explanation:

The gravity model is a model that describes the flow of traffic between two points. This model is based on the idea that the flow of traffic between two points is proportional to the product of the populations of the two points and inversely proportional to the distance between the two points.

In a logistics network, what is the transshipment problem?
