QLVT CH4

What is the primary objective of Vehicle Routing Problems (VRP)?

• Minimize fuel consumption
• Maximize delivery time
• Optimize transportation routes
• Reduce the number of vehicles used

Answer explanation

VRP focuses on optimizing transportation routes to minimize costs and improve efficiency, taking into account vehicle constraints and delivery requirements.

Which transport network type includes intermediate hubs for sorting and consolidation?

• Direct delivery
• Tour-based transport
• Network-based transport
• Single-destination transport

Answer explanation

Network-based transport uses hubs for sorting and consolidation, allowing goods to be delivered efficiently to multiple locations.

What is the advantage of a milk-run delivery network compared to direct shipping?

• Lower transportation costs
• Higher inventory levels
• Faster delivery to single points
• Simplified coordination

Answer explanation

Milk-run networks reduce transportation costs by consolidating deliveries to multiple destinations within a single trip.

In a supply chain, what is the main purpose of a distribution center (DC) with storage functions?

• Increase transportation frequency
• Act as a simple transit point
• Store inventory for later use
• Serve as a customer point of sale

Answer explanation

Distribution centers with storage functions consolidate and store goods, enabling more efficient distribution to customers.

What is the main disadvantage of direct shipping to multiple destinations?

• High transportation costs
• Low inventory levels
• Increased complexity of coordination
• Reduced frequency of deliveries

Answer explanation

Direct shipping to multiple destinations often incurs higher transportation costs due to the lack of consolidation.

In a capacitated vehicle routing problem (CVRP), what is a critical constraint?

• Delivery time windows
• Vehicle capacity
• Total number of stops
• Route length

Answer explanation

CVRP focuses on optimizing routes while ensuring that vehicle capacity constraints are not violated.

What is a characteristic of a dynamic VRP (Vehicle Routing Problem)?

• Routes are fixed before dispatch
• Real-time adjustments are possible
• Involves only single depot
• Focuses on long-term transportation planning

Answer explanation

Dynamic VRPs allow for real-time adjustments to routes based on new orders or conditions during transportation.

What is the trade-off of centralized inventory management in supply chains?

• Higher storage costs
• Increased demand uncertainty
• Lower transportation costs
• All of the above

Answer explanation

Centralized inventory management reduces transportation costs but increases storage costs and demand uncertainty.

Which transport mode is considered the most efficient for large-volume international shipments?

• Rail
• Air
• Ocean shipping
• Trucking

Answer explanation

Ocean shipping is the most efficient for large-volume international shipments due to its ability to handle bulk cargo economically.

What is the primary purpose of the milk-run delivery system?

• Reduce delivery time to customers
• Consolidate shipments to multiple stops
• Increase storage requirements
• Decrease vehicle utilization

Answer explanation

Milk-run systems consolidate shipments to multiple stops, optimizing transportation efficiency and reducing costs.
