Zorluk: OrtaTransportation Modes and Network Connectivity

A logistics planner is evaluating the cost structure of different freight transport modes across varying distances. Based on the principle of tapering costs (the relationship between fixed terminal costs and variable line-haul costs), which of the following best explains why water transport is the most economical choice for long-distance movement of bulk freight?

  1. Water transport has high fixed terminal costs but low variable line-haul costs per kilometer, reducing the average cost significantly over long distances.Cevap
  2. B
    Water transport possesses the lowest fixed terminal costs of all transport modes, making it cost-effective even for short-distance routes.
  3. C
    Water transport provides maximum door-to-door flexibility and speed, eliminating the need for intermodal transfers.
  4. D
    Water transport line-haul costs increase exponentially with distance while terminal costs decrease to zero.

Cevap

Water transport has high fixed terminal costs but low variable line-haul costs per kilometer, reducing the average cost significantly over long distances.
Water transport requires substantial initial capital investment in port infrastructure and cargo handling, resulting in high fixed terminal costs. However, because ships carry immense volumes of bulk cargo with low surface friction, the variable line-haul cost per ton-kilometer is extremely low. Over long distances, the fixed terminal cost is spread over many kilometers, making water transport the most economical choice.

Adım Adım Çözüm

1
Analyze transport cost components
Total transport cost consists of fixed terminal costs (port loading/unloading facilities) and variable line-haul costs (fuel and movement costs per kilometer).
Understanding tapering cost curves requires distinguishing between fixed loading charges and line-haul operational expenses.
2
Evaluate modal cost trade-offs
Road transport has low terminal costs but high line-haul costs (best for short distances). Rail occupies an intermediate position. Water transport has high terminal costs but very low line-haul costs due to large vessel capacity and low friction.
Water transport requires long distances so that the initial high terminal cost is diluted over many kilometers.
3
Select the correct option
The option identifying high terminal costs coupled with low variable line-haul costs accurately explains water transport's long-distance economic advantage.
Directly matches transport economic principles for modal choice.
