13. What is cross docking ?
Cross-docking is a practice in logistics of unloading
materials from an incoming transport unit and loading
these materials in outbound transport unit, with little or
no storage in between.
This may be done :
• to change type of conveyance,
• or to sort material intended for different destinations,
• or to combine material from different origins.
In purest form this is done directly, with minimal or no
warehousing.

24. Product selection
For example, Home Depot chooses which
products go through its crossdocks after
carefully analyzing current inbound
transportation costs and ease of handling.
Items such as lumber and awkward
If demand is uncertain, industrial supplies are all taken directly to
crossdocking is difficult the stores, rather than being run through
because matching supply and the crossdock, because any savings in
demand is diffcult. transportation costs would be oset by
excessive handling costs.

demand for the product must be suffcient to
warrant frequent shipments. If demand is too low,
frequent shipments lead to excessive inbound
transportation costs, and the warehouse would be
better holding stock rather than crossdocking.

26. Planning and Designing the Operation
because most cross-docking activity is concentrated at receiving and loading docks,
Dock-area • adequate number of dock doors (1 / 500m2)
layout and capacity • Where possible, eliminate racks to create more dock space.
• Make sure product can flow quickly and freely through the DC.
• Visible floor layouts, processes and systems.
• Well laid out visible floor areas to enable management by sight.
• Clear floor policy at end of shift periods.
to comply with the rigid schedules needed for cross docking,
Yard
Management • you may need a yard tractor and trained driver to move trailers around the yard.
• A yard manager must also be on hand to ensure that trucks are spotted at the right doors at the right
times, resolve equipment issues, and coordinate incoming and outgoing trucks so that delays can be
avoided.
Because it’s important to move large volumes of product in a short time.
Material Handling • Using double pallet jacks to transport pallets can double throughput.
Equipment
• Conveyors that are installed on the floor of truck trailers and connect to inbound and outbound pallet
conveyors within your facility can significantly speed up pallet transfer
• Where appropriate, powered extendibles can aid in loading and unloading cartons as well.
When it’s time to choose managers for a new cross-docking operation, remember that forward
thinking is a critical success factor.
Personnel • Cross docking cannot fully achieve its objectives without a good core of receiving/shipping
supervisors and logistical planners who can identify product that needs to be cross docked and redirect
personnel to make it happen. Supervisors must be able to recognize opportunities for pre-receiving or
pre-allocating receipts before the actual product arrives.
• Training at both the supplier and DC locations will be necessary. For the supplier, training on the
specific requirements (as noted in policies/procedures) of a customer must be developed.
• For the DC, training on how to handle cross-dock product versus standard receipt-to-storage product
will be necessary.
26
27. Planning and Designing the Operation
Quality communication
– Clear inbound information flows of what is due to arrive.
– Clear outbound information flows of what, where and when goods need to be shipped.
– Clear product labelling and routing information on all pallet consignments.
Enabling communication technologies
– EDI
– Serial Shipping Container Code (SSCC)
- The benefits of the SSCC are:
» Logistics Units are identified with a worldwide unique number
» Provides a link with bar coded information on a logistics unit and the
information that is communicated between trading partners via
electronic business transactions.
» All numeric structure leads to faster data processing
real-time IS are preferred to paper-based systems
– RF (RFID??)
– it’s important to not only capture data in real time but to also utilize it right away.
- fill discrepancies in real time.
Cross Docking relies on continuous communication between Wal Mart’s suppliers, distribution
centers, and every point of sale system in each store.
For this purpose, Wal Mart operates their own satellite network that sends the point of sale
(POS) data directly to 4,000 vendors.
Centralize your
organization One strategy that retailers use is to have centralized buyers determine what gets shipped to stores,
instead of the stores themselves; that is, it is strictly a push distribution system and there is no need
to carry safety stock. The buyers have effectively taken all variance out of the demand (from the
retail outlets, not from the customer). Retailers like Wal-Mart and Ross Stores use this technique.
27
28. Implementation and Maintenance
start with
a pilot program
That will allow you to study the effects of cross docking on a small scale and
resolve any weaknesses before rolling it out to an entire product line or network of
facilities.
Be prepared
for contingencies
This may include keeping a small inventory of cross-docked product in your
facility.
Standard operating
procedures
Standard operating procedures should also be in place so orders are not delayed
and product can still be cross docked even when fewer units than expected are
received (perhaps due to miscounts or damage).
Continuous
Improvement
Once your cross-docking operation is up and running smoothly, don’t sit back and
assume that your job is done. Supply and demand conditions change constantly,
so periodically monitor cross-docked products to determine their sustainability in
your program.

31. When cross docking replaces warehousing,
a number of benefits follow

McCain Foods USA Inc
Cross-docking enables Wal-Mart to achieve the “We saved 20% to 30% in total warehouse costs by not
economies that come with purchasing full truckloads sending product into storage. And that’s with just one

34. Challenges to consider
Defining Cross Docking areas, consider the following :
– A. Lead Times and Security Stocks should not become so high that
» Time to market is lost
» Security Stocks become to high
Otherwise Cross Docking becomes Pointless
– B. Sub Regions should be defined
- 1 Cross Docking area for all Russia seems difficult
- C. Cross Docking should not be the security net of the buying
departments
- “If we can’t source locally – we’ll cross dock” is not always
the best algorithm
- “If we can’t produce locally – we’ll cross dock” is not always
the best algorithm
- D. With important regional development, cross docking centers may
- move on the map (to east, to south)
- Become more numerous
34
36. Challenges to consider
1. Responsibility 6. Work load balance among gates
• Divided between the parties, therefore further
clarification is needed
2. High control culture
• Control vs efficiency
• Is an obstacle to Cross Docking, SSCC, etc.
Control Efficiency
3. Far small stores can not receive too
“Consolidated” volumes
• For instance 20t truck to convenience store !
4. Bulk and weighted products
• Make a decision between average case estimated 12% reduction

43. Cross Docking is one of the answers to the new retail
challenges in Russia
• Moving growing ranges of volumes,
– quickly,
– across a large country (continent),
• Gaining in competitiveness
• Gaining in customer service level
• Decreasing the inventory pressure all along the Supply Chain
43
44. Golden Rules / Changes in traditional philosophy
COLLABORATING extensive coordination between the distributor and its
suppliers and customers
• Implementing a cross-docking operation often means that channel partners may
experience at least a few headaches along the way.
RELYING increased requirement for quality in receiving.
• there is no time to inspect quality on the receiving dock. Ideally, this would
eliminate counting as well, although this level of confidence is rare.
COMMUNICATING Increased communications between channel partners
• important challenge of the extended supply chains on the side of I+C is that
information flow must be assured through passing company limits.
RECONSIDERING costs along the supply chain
• channel partners may experience increased costs
• But the savings associated with crossdocking must always overcome these extra
costs for the system to be viable.
