TL Background Information

No barrier to entry 500,000 interstate carriers 80% operate 20 or fewer trucks 72% operate 6 or fewer trucks

Industry issues Fragmentation Severe competition Very low margins High fuel cost, fuel surcharge Driver shortage and high turnover

LTL Transportation

Page 28: Supply Chain Models: Logistics

LTL Transportation Background

LTL trucking requires a large investment in facilities Few major national and regional carriers

For national carriers, tendency for smaller number of facilities Interlining traffic to gain geographical coverage at the required service frequency

Relatively stable driver workforce Major players:

Roadway Express Yellow CNF American Freightways (FedEx) Arkansas Best U.S. Freightways

Page 29: Supply Chain Models: Logistics

LTL Transportation Background

Typical shipments vary in size from 100 to 10,000 pounds

Going directly from shipper to consignee is not economical

Shipments are typically transported via a hub and spoke system: Shipper to origin spoke (satellite terminal) Origin spoke to origin hub (breakbulk terminal) Origin hub to destination hub Destination hub to destination spoke Destination spoke to consignee

Impact of Rail

Carries more than 40% of nations intercity freight70% of automobiles from domestic mfgs64% of nations coal40% of nations grain

Class 1 rail freight volume in 1998 was 1.38 trillion ton-miles

Intermodal volume (trailers & Containers) has nearly tripled in the past 20 years

Air Cargo Transportation

Page 42: Supply Chain Models: Logistics

Air Cargo Background

International air freight is 16 million tons 2% of total tonnage but 33% of value traded Annual traffic growth rate is 7.5% Robust growth due to:

Just-in-time manufacturing and retailing Strong China growth Improvement in Asian crisis markets

Air cargo key commodities are electronics, perishables, fashion apparel, and live animals

Page 43: Supply Chain Models: Logistics

Top Air Cargo Carriers

Top 10 air cargo carriers are: Federal Express Lufthansa UPS Korean Airlines Singapore Airlines

Air France Japan Airlines British Airways KLM United Airlines
