供应链管理第三版 Unit14 习题与答案Chapter 14Transportation in the Supply ChainTrue/False1. Transportation plays a key role in every supply chain because products areusually produced and consumed in the same location.Answer: FalseDifficulty: Easy2. Freight transportation costs in the United States amount to about 6 percent of theGDP.Answer: TrueDifficulty: Moderate3. The shipper is the party that requires the movement of the product between twopoints in the supply chain.Answer: TrueDifficulty: Moderate4. The carrier is the party that moves or transports the product.Answer: TrueDifficulty: Easy5. A distributor makes investment decisions regarding thetransportationinfrastructure and then makes operating decisions to try to maximize the returnfrom these assets.Answer: FalseDifficulty: Hard6. A carrier uses transportation to minimize the total cost (transportation, inventory,information, and facility) while providing an appropriate level of responsiveness tothe customer.Answer: FalseDifficulty: Hard7. The vehicle-related cost is incurred whether the vehicle is operating or not and isconsidered fixed for short-term operational decisions by the carrier.Answer: TrueDifficulty: Moderate8. Vehicle-related cost includes any cost associated with terminals, airport gates,and labor that are incurred whether vehicles are in operation or not.Answer: FalseDifficulty: Moderateshall not exceed the level of stator core, or arc skateboards, protection of stator plate rollover may occur), reasonable to generally should be centralized. Avoid layout vulnerable to mechanical damage, damp, vulnerable to corrosion and vibration, ensure as far as possible with the platform stairs, lifting devices, cover plates, electrical enclosures and other intervals at arm's length. Piping support and hanger set weight of the weight and its insulation shall meet reasonable piping displacement, increase system stability, prevention of pipeline vibration displacement in operation. Process piping support and hanger spacing are shown in table 1. Process piping in the drain pipe must have a certain slope (about 0.002-0.004) to drain. Enter the pipe should be smooth flow to the lateral, intake manifold into the expansion tank should be considered order, low pressure or high pressure drop near the expansion tank inlet. Pipe deflection and expansion must be considered the absorption problem, consider the natural direction of the pipeline using the small pipe to achieve thermal expansion compensation and, if necessary, consider9. Trip-related cost depends on the length and duration of the trip but isindependent of the quantity shipped.Answer: TrueDifficulty: Easy10. Trip-related cost includes loading/unloading costs and a portion of the fuel costthat varies with the quantity being transported.Answer: FalseDifficulty: Easy11. Overhead cost includes the cost of planning and scheduling a transportationnetwork as well as any investment in information technology.Answer: TrueDifficulty: Moderate12. A carrier’s decisions are affected by the prices that the market will bear, but notthe responsiveness it seeks to provide its target segment.Answer: FalseDifficulty: Moderate13. Transportation cost depends on the prices offered by different carriers and theextent to which the shipper uses inexpensive and slow, or expensive and fast,means of transportation.Answer: TrueDifficulty: Easy14. Rail is the dominant mode of freight transportation in the United States andaccounts for over 75 percent of the nation’s freight bill.Answer: FalseDifficulty: Moderate15.
