Introduction

  • “...freight transportation is vital to the Nation's economy. At any given moment, billions of dollars' worth of goods are being moved by truck, train, ship, or barge, or held in a yard for transport or distribution.”

How important is transportation l.jpg

How Important is Transportation?

How is this done l.jpg

How is this done?

  • 6.3 million rail cars

  • 25.2 million trucks

  • Over 300 ships with the capacity of 2,000-5,000 containers


Purpose l.jpg

Purpose

  • Evaluate the 4 main modes of Transportation

    • Truck—semi-tractors

    • Rail

    • Ocean Carrier

    • Air Carrier

  • Industry Trend

  • Exercise

  • Summary


Semi tractor l.jpg

Semi-Tractor


Semi tractors l.jpg

Semi-Tractors

  • U.S Department of Transportation defines a semi-truck as:

    • A commercial vehicle operating on the interstate highway system or divided highways to move material or people for compensation

    • Generally, have 3 axles—common configruation 10 wheels

    • Gross combination weight rating, of 4,536 kg (10,001 pounds) or more


Semi tractor segments l.jpg

Semi-Tractor Segments

  • Semi-tractors segments:

    • Single-axle, up to 20,000

    • Tandem-Axle, up to 34,000

    • Gross vehicle weight over 80,000

  • Semi-Tractor lengths

    • Minimum 24 and maximum 75 feet long


Truck transportation evaluation l.jpg

Truck Transportation Evaluation

  • Advantages

    • Greater control of over delivery locations-flexible

    • Less pilferage of goods

    • Last mile service

  • Disadvantages

    • Increase traffic congestion

    • Higher rate of traffic accident


Railroad l.jpg

Railroad11 l.jpg

Railroad

  • Railroad is divided into 3 segments

    • Light rail

    • Rapid transit

    • Freight train


Railroad evaluation l.jpg

Railroad Evaluation

  • Advantages

    • Most efficient mechanized land transport

    • Very safe

    • Cheaper than trucking

    • Greater load capacity


Railroad evaluation13 l.jpg

Railroad Evaluation

  • Disadvantages

    • Rigid routing destinations—inflexible

    • Multiple handlings of goods—leads to delays

    • Expensive infrastructure

    • Not suited for smaller loads or short distances


Ocean freighters l.jpg

Ocean Freighters


Ocean freighters15 l.jpg

Ocean Freighters

  • Ocean Freighter segments

    • Bulk Carriers—carry bulky and dry items, i.e. coal or grains

    • Tanker Carriers—designed to haul liquids, i.e. oil

    • Container Carriers—carry cargo in truck size containers (TEU)


Ocean freighters16 l.jpg

Ocean Freighters

  • Categorized by capacity or the canals a ship can travel through

    • Handymax—smallest carrier, less than 50,000 dwt

    • Aframax—tankers between 75,000-100,000 dwt

    • Suezmax—largest carrier to pass through the canal, 125,000 to 200,000 dwt

    • ULCC—largest tankers with displacement between 320,000 to 500,000 dwt

Ocean Freighters Evaluation

  • Advantages

    • Cheap

    • Very few accidents

    • Best for dry and bulky items—steel or oil

    • Largest hauling capacity

    • Most efficient hauler for fuel consumption


Ocean freighters18 l.jpg

Ocean Freighters

  • Disadvantages

    • Slow

    • Bad for perishable or time sensitive goods

    • Limited to water routes


Air freighters l.jpg

Air Freighters


Air freighters20 l.jpg

Air Freighters

  • Large modified passenger planes that are used to carry freight. Most common models are the following:

    • Boeing 747, 737,

    • Airbus A320, 340

    • Airbus Beluga


Air freighter evaluation l.jpg

Air Freighter Evaluation

  • Advantages

    • Speed of delivery-best for time sensitive items

    • Best for time defined deadlines

    • Reduces traffic congestion

    • Best for smaller and less bulky items

    • Seamless integration of plane to truck delivery solution

  • Disadvantages

    • Very expensive

    • Not for large bulky items

    • Less carrying capacity than ocean transporters


Industry trend l.jpg

Industry Trend

  • Intermodal

    • Uses several types of transportations en route

    • Uses a truck for pick-up and delivery, but the long haul uses either rail/ocean

    • Utilizes each modes of transportations’ efficiencies


Activity l.jpg

Activity

You have received a report that your company’s new

Gazogle toy is outselling the company’s highest

expectation in the mid-west region. Store

managers in the mid-west are demanding another

shipment of Gazogle before the holiday season to

replenish their low inventory levels. As the

company’s logistic manager, you need to figure out

the cheapest method to transport the Gazogle from the

factories in China to Chicago. You must also ensure the toys

reach the mid-west stores prior to the holiday

season, which is 18 days away.


Activity cont l.jpg

Activity Cont.

  • Compute the cheapest method and route to ship the toys from China to Chicago using any single or combination of modes of transportation and make sure the toys arrive before the holiday season.


Activity data l.jpg

Activity Data

  • Hint: # of Units Required means that several planes, trucks or railroad cars will be needed to transport the entire shipment.

  • Assume—Railroad can deliver the goods to the final destination.


Activity solution l.jpg

Activity Solution


Summary l.jpg

Summary

  • Trucking—very flexible to your needs, but prone to accidents

  • Rail—most economic land transportation, but limited in final destinations

  • Ocean—inexpensive, but slow

  • Air—moves at the speed of business, but with a cost


Final thought l.jpg

Final Thought

  • “…quintessential requirement for succeeding in a global, just-in-time economy is the ability to plan trips, deliveries, and transactions down to hours and minutes.”
