Pressure
to improve customer service and in-stock rates is pushing more companies
to abandon the “consolidation” model in favor of a flexible, agile
network of regional distribution centers
BY THE END OF
THE 20TH CENTURY, INVENTORY HAD become about as welcome to most
corporate comptrollers as a telecom analyst at an ethics convention.
Though acknowledged to be a necessary evil, it was still viewed
as that balancesheet line item that tied up a lot of the corporation’s
cash and required a lot of expensive space to house. To tame the
inventory monster, U.S. business went into overdrive, striving to
keep inventories lean, operating in just-in-time (JIT) mode and
consolidating distribution centers.
At least, that’s
what we thought. But the reality is, well, something completely
different. Warehouse space actually stands at an all-time high.
“Today, there’s more square footage of warehouse space than at any
point in U.S. history,” Ted Scherck, president of the Colography
Group, told a session at the annual Council of Logistics Management
conference.
Scherck’s assertion
is corroborated by an analysis conducted by warehousing provider
ProLogis of the 42 major markets in which it competes. That study
showed that warehousing space increased to 3.4 billion square feet
in 2002, up from some 3.1 billion two years ago. “The occupancy
rate has likely declined in the last two years,” says John Siebel,
president and COO of North America at ProLogis, “but the gross square
footage has increased.”
The hard truth
is that although inventory reduction receives a lot of lip service,
inventory levels in many industries have stayed the same or increased
over the long term. That trend is particularly evident with finished
goods. “Management has cleaned up [its] production and ordering
processes for raw materials, but [it has] less control of finished
goods,” says Jim Ginter, professor of marketing at Ohio State University’s
Max Fisher College. Ginter, who headed up a study that examined
various types of inventories across major industries over a 20-year
period ending in 1999, adds that the apparel, grocery and medical
products industries,in particular, recorded inventory increases.
By contrast, real decreases were found in finished-goods inventories
for electronics and computers, due in large part to the supply chain
model made famous by Dell.
Also contributing
to the more-not-less inventory phenomen on may be the proliferation
of product varieties offered in recent years. Plus, vendor-managed
inventory, JIT and other drives to improve the supply chain management
process at many companies have, as Ginter puts it, placed “power
increasingly downstream, at the retail level, nearer to the customer.”
This means inventory gets thrown back upstream. And it has to be
warehoused somewhere.
When “pull”
is the trigger
Another development that is helping kick regional warehousing into
high gear is the growing popularity of “pull” demand chains, whereby
stock replenishment is triggered by consumer demand (i.e.,sales)
rather than, say, manufacturers’ promotions. It’s pretty much a
given that if this model is to succeed, inventories need to be maintained
close to their point of sale—which typically means in regional warehouses.
One company
that has adopted this strategy is Best Buy, the nation’s largest
consumer electronics retailer. Best Buy has gone to great lengths
to minimize its response time when a need is defined at the store.“If
we had a great day of sales,” says Chas Scheiderer, Best Buy’s senior
vice president of logistics,“we need to get products back on the
shelf.”
Although it’s
a national retailer, Best Buy relies heavily on regional distribution,distributing
products to stores from six general merchandise DCs (distribution
centers) around the country, with an additional East Coast facility
slated to open in the first half of this year. These facilities
all support the continually expanding roster of Best Buy stores
— there were 538 at press time—as well as the Musicland group of
stores, which include Sam Goody, Suncoast and Media Play. Best Buy
distributes media such as CDs and DVDs from a dedicated entertainment
facility in the Midwest. In addition, it operates several other
DCs that are dedicated to large - ticket items such as appliances
and big - screen TVs where deliveries are cross - docked, moving
swiftly to stores or directly to customers.

MODELING TO DETERMINE WHICH OF ITS SIX REGIONAL WAREHOUSES SHOULD
HOUSE ITEMS LIKE THESE TRADE BOOKS. |
To guarantee
the best possible ground service, Best Buy uses a dedicated fleet
through a long - term agreement with a truckload (TL) carrier that
picks up shipments from vendors and delivers products to the stores
on a twice - weekly basis with room to tweak deliveries as needed.
It also uses contract carriers as needed or inselect markets on
a regular basis.
Going postal
Another high - profile company that has become a convert to regional
distribution is Amazon.com. As a renegade dot-com startup in the
mid 1990s, Amazon.com used one Seattle-area facility to serve the
country as the first online bookseller.
Over the last
few years, however, as its business model has morphed from that
of a dot-com fulfillment company to that of a giant retailer, Amazon.com
invested in state-ofthe-art DCs and boosted its product mix. The
company now sells not only books, but also apparel, toys, electronics
and even hardware, whether via marketing agreements, partnerships
or acquisition.
Today, six Amazon.com
DCs dot the country, including a large facility in Nevada and two
in Kentucky. (Amazon.com shuttered its Seattle DC in early 2001.)
“We try to perform mathematical modeling to determine which are
the fastestmoving products and which DCs those products should be
in,” says Carrie Peters, an Amazon.com spokeswoman.
“All DCs are
located close to airports or transportation hubs,” Peters adds,
which allows the e-tailer to ship items within 24 hours of order
receipt. It makes no guarantees, but most items are received by
the customer within two to three days via its carrier partners UPS
and the U.S. Postal Service (or via FedEx if the customer requests
premium delivery service).
Down the
road
The shift toward regional distribution has implications for the
trucking industry as well.An analysis by the Colography Group reveals
that shippers are pulling back on their use of long-haul less-than-truckload
(LTL) moves. Though the long-haul segment is experiencing only moderate
average annual growth and intermediate-distance moves of 600 to
1,800 miles are actually declining, short-haul LTL moves of 600
miles or less (in one-way movements) are seeing high growth rates.
At the same
time, companies are moving consolidated or truckload shipments along
longer-haul routes, according to year-over-year trend data from
a study conducted annually among several hundred large shippers
by the University of Tennessee, Georgia Southern University and
Cap Gemini Ernst & Young. Mary Holcomb, associate professor of logistics
at the University of Tennessee, suggests that improved supply chain
management, primarily stemming from the use of transportation planning
and load optimization software, is driving the trend. Another contributing
factor may well be the increased use of third-party logistics providers
(3PLs), which are masters of load consolidation.
Ultimately,
Scherck of Colography Group sees more companies developing what
he calls “an optimal mix of strategically located inventory and
short-haul distribution.” He cites the example of a large home-products
retailer that keeps fewer windows and doors in stock than it used
to. But that doesn’t mean it has cut back on its use of warehousing
space. Instead, it relies on direct shipments from its DC to the
consignee.“ It’s true that efficient supply chains change the number,
location and physical layout of storage space,” Scherck notes, “but
this does not mean that storage space goes away.”
