As the start and end point for material movement within a facility, docks offer many opportunities for speeding product flow that can have a positive impact throughout the supply chain.
Too often, the dock represents
the black hole of the logistics
universe. Or, to bring it down
to earth and closer to home, it can be as messy and disorganized as a
kid's closet. However managers picture the
place where their company shakes hands
with the rest of the supply chain, the shipping and receiving docks offer opportunities to improve the material and information flows that pass through them.
Unfortunately many companies miss
that opportunity because the dock is a
convenient place to stow and forget stuff
that comes in unexpectedly or is set to go
out eventually. Such clutter starts small,
but leads to disorganization, delayed shipments and a hazardous work environment. This problem is amplified when there's
minimal dock space supporting both receiving and shipping operations.

safety. That's why, in
moving to a larger facility in Elgin, Ill., it was
important for John B. Sanfilippo & Son, Inc.
(www.fishernuts.com), to make sure product and information would flow smoothly
through the new docks. The company is one
of the fastest growing nut processors and
packagers in the United States.
"We want everything to be orchestrated
from the point of accepting the raw peanuts and nuts all the way to the back door
with the finished product going out to the
customer," says Tom Meyer, facilities manager for the company.
The dock area plays an important role
in helping this new 1.7 million sq.-ft. facility keep information as fresh as the nuts it
handles. When we talked to him, Meyer
and his staff were in the process of selecting
a warehouse management system (WMS)
that will help them track product from the
time it comes into the receiving docks until
it goes out the shipping docks. That's critical not only for guaranteeing freshness in
this facility, but for freshness in the customers' facilities as well.
"We do a lot of warehousing for individual customers so if we do not send them
the freshest product possible, especially
if it sits in their warehouses for a while,
there's a possibility for lower quality product by the time it gets out of the customer's
warehouse," Meyer says. "If the customer
doesn't rotate product in his warehouse the
way we do, by the time it gets to the stores
it won't be as fresh."
Most nuts arrive via shipping container
from overseas. The company maintains
forecasts tracking when containers are
due. These containers are staged in a receiving area outside the building's receiving docks. Once delivered to a dock door
the nuts are inspected for freshness and
FDA specifications. They are then given
bar codes, scanned into the system, and
given a location in the cooler. Next, the
nuts are either roasted for stock or for a
customer's requirements.
Dock Security
and Safety
Sanfilippo & Son will be moved out of
its Elk Grove, Ill., distribution center by the
end of this year. Managers expect to consolidate manufacturing operations from
Elk Grove and Arlington Heights, Ill. into Elgin by 2010. The docks in the new facility were designed to handle the additional
capacity. Meyer learned some valuable
lessons about loading and receiving docks
from those other facilities. One of the most
important: No more interior docks.
"Exterior docks mean much less of a
chance for building damage, because we had a terrible time with trucks hitting
our building in Elk Grove due to the
compactness of the doors," Meyer says.
"With all outside docks, it will also help us
with heating and cooling the building."
August through January is the company's peak period for receiving freshly
harvested raw nuts. During those months it may receive 300 to 400 trucks a day.
Changing from the old dock management mindset to a new one was a learning process for dock employees.
"We had the old standard pit plates before and our people were used to opening
the door, throwing down a dock plate and
going," Meyer says. "We didn't have the
lock mechanisms for the trailers before,
either. We just used the standard chocks."
In the new facility Sanfilippo & Son
installed Serco (Carrollton, Texas, www.sercocompany.com) Master Control
Panels to coordinate the operation of 76
shipping and receiving dock locations.
Each is equipped with:
- Vertical levelers—by storing erect
these levelers open up dock space for better traffic flow.
- Safety-Loc SLP vehicle restraints—
installed in a pit under the leveler.
- Dock seals—with compressible foam
on steel frame to absorb truck force
and protect the building; the seals wrap
around the truck trailer to prevent moisture from entering the dock area.
Employees can operate all the equipment for each dock position from a central
control panel. A manually operated door
is interlocked with the other dock equipment, thanks to a photo sensor specified
by Sanfilippo's dock equipment dealer, the
Paul Reilly Company (Glendale Heights, Ill., www.paulreillycompany.com).
Once a truck is parked at the dock, the operator uses the control panel to actuate
the restraint, but not the dock leveler until
the restraint is fully engaged. When the
truck is ready to leave, the restraint cannot release the truck unless the leveler is
in the stored position and the dock door
is closed.
Nuts are a low margin business. Every
department at Sanfilippo does its part
to move products through the system at
minimum cost. Thanks to the systems
controlling traffic through the docks, efficiency and safety go hand in hand. Only
authorized people can access the dock.
Cameras ensure internal and external
security. The dock plates won't operate
unless a truck is in place. Trucks are assigned a door by the guardhouse. The guardhouse then notifies the shipping
department that a specific truck is coming to a dock.
"There's a check and balance situation
that drives accountability for each load,
and that includes the lift truck driver servicing each truck," Meyer concludes.
Accelerate Truck
Turnaround
Dock systems linked to warehouse
management systems (WMS) and yard
management systems (YMS) should be a
no-brainer, according to John Hill, principal of ESYNC (Toledo, www.esync.com), a logistics and systems integration
firm. "But some clients still ask, ‘You can
do that?'"
Facility managers need to open their
minds when it comes to the dock. "It
ought to be the place where there's the
least amount of unnecessary storage if
people are going to execute the receiving and shipping process effectively,"
Hill adds. "It makes a lot more work
for those charged with picking up your
shipments when they have to navigate
around clumps of material that don't belong there. It could delay shipments and
create safety problems."
Drew Kronick will testify to that. He's
executive v.p. of Velocity Express (Westport, Conn., www.velocityexpress.com),
providers of customized, on-demand delivery services. Kronick advises clients on
how to make best use of his services, and
much of that advice has to do with dock
management.
"Customers have put tight constraints
on me in the JIT environment," he says.
"I have 60 minutes in my facility to strip,
scan and load packages onto another vehicle and be on the road. In my customer's environment, those packages and
pallets have to be organized in a way that
we can do things quickly with them."
The organization and planning that
need to happen on the shipper side is
the most important thing that happens
on the docks for expedited service providers. It can also be the most difficult
part of the shipper's job in doing business with them.
"We impose big discipline on our customers, but the reward is you don't have to
give me a trailer at 7:00 at night," Kronick
says. "I'll take it at 5:00 in the morning. So
you can have a whole extra shift to pick
that freight."
Here are a few other pieces of advice for
the loading and receiving docks that won't require too much effort:
- Consider allocating more people to the
dock on a part-time basis. This will result
in less cost if freight can be organized for
quick loading. It also requires fewer drivers
on the expedited service provider's side if
those drivers can get loaded and rolling
without delay.
- Look at the total dollars
spent on labor allocation at the
dock as well as the infrastructure, and find the low-hanging
fruit. Tactical things like dock
levelers, truck restraints and
shelters may be easier to implement than more strategic things
like staging and scheduling.
- Consider introducing an
expedited service provider to
customers. "The more we can
understand about what their
expectation is and what's been
sold to them, the easier it is for
us," Kronick says.
A Window to the Yard
A YMS can act as an extension of a WMS in pushing information management beyond the dock door. Such systems are
typically focused on high-volume operations where a company
may not be able to process incoming items immediately. Staging
them in trailers parked in the yard can take pressure off the dock
for a while. Then, when the facility is ready for the materials, the
YMS dispatches a yard jockey to the designated location, picks up the load and pulls it up to
the designated dock.
A real-time locator system can make this process
run smoothly. It does at Jobstl Warehousing & Fashion
GmbH (Graz, Austria, www.joebstl-warehousing.com), a
European third-party logistics company that distributes
fashion merchandise for the
Charles Vogele Group (Zurich, www.voegele-mode.com). Vogele operates more than
750 clothing stores in Austria,
Belgium, Germany, Switzerland and the Netherlands.
Jobstl uses an active RFID real-time locating system from
WhereNet (Santa Clara, Calif., www.wherenet.com) to assist
its dynamic shipping and receiving operation. The system
automates yard management processes and provides complete
closed-loop supply chain visibility so logistics personnel and
retail store managers know the precise whereabouts and status
of every shipment of women's dresses, men's suits and other
fashion items en route to Vogele's stores. What does this have
to do with the dock?
"Our constant increase in turnover volumes and our limited number of docks made it necessary to
optimize processes at the docks and
on the property itself," explains
Marius Reber, head of warehousing for Jobstl. "Today, we are able
operate the loading docks at optimum capacity. We've increased our
turnover of goods manifold without having to invest in additional
employees or dock expansions."
Jobstl employees use handheld devices at the docks to scan each item loaded into the trailers. This data generates a freight list, which is then married with the container's tag data and transferred
to Jobstl's transport dispatch. Afterwards, each container and
its contents can be clearly identified through the WhereNet
system.
"The system gives us the ability to make the entire logistics
process transparent," says Reber. "It can track the flow of goods
to branch offices, can measure the service level and maintains a
constant overview of operations on the property. We use the data
to analyze and optimize our logistical processes at the dock and in the yard while having information relevant to billing at our fingertips in a real-time setting. Our
employees were also relieved from
a multiplicity of manual tasks."
The system shows Jobstl managers, in real-time, the loading
status of containers. Because
yard drivers always know where
each container is and what's in
it, there are no choke points in
the yard. Another plus: Jobstl
requires 20% fewer containers
than before. That means they no
longer need to lease extra containers during peak periods.
Finally, Jobstl has enjoyed a significant reduction in dock
door and yard turn times, resulting in increased throughput.
Customers and employees can now focus on managing by
exception and on adding value rather than chasing down
information at the dock or in the yard.
Managing dock operations is more than managing doors.
It's all about carrier scheduling, order management and maintaining good human resources. Paying attention to these basics
will contribute mightily to supply chain efficiency.
