88
Warehouse Events
• Types of events– Trailer arrivals– Trailer departures– Receipts– Shipments– Counts– Damage
• How many? How long? Resources?
89
Item Activity
• Activities– Receipts, Putaway, Counts, Picks by UOM by type of order
• Information used for profiling– Determine cycle counting frequency– Determine storage profiles– Determine picking profiles– Determine resources needed
90
Location Activity
• Track events performed at a location• Used to adjust warehouse layout• Adjust number of locations available for
– Storage by zone– Storage by item
91
Resource Utilization
• Equipment– Hours of use– Percent utilization– Hours of downtime
• People– Hours per day on direct activities– Percent utilization– How much accomplished per hour– Number of units per hour
92

93
WMS Functionality
94
Scheduling Appointments
• Purpose– Control traffic to the facility
• Types of Appointments – Inbound (deliveries)– Outbound (pickups)
• Drop vs. Live considerations
95
Inbound Appointments
• Based on requested delivery date• Shipper or carrier calls for an appointment• Drop or Live• Check authorization to deliver
– Reference purchase order number
96
Inbound Appointments• Estimate time to unload
– Floor loaded vs. palletized– Mixed or full pallets– Number of pallets, cartons, total weight, etc.
• Assign date and time based on capacity– Dock calendar– People availability– Other arrivals already scheduled
97
Outbound Appointments
• Pickup appointment based on delivery requirements
• Warehouse calls the carrier– EDI
• Customer pickups – Customer normally specifies the pickup time
98
Outbound Appointments• Based On delivery appointments
– Traffic planner builds loads– Travel times are planned– Customers may impose limitations– Transportation restrictions may come into play
• Availability of trailers, etc.
– Appointment is to pick up the load based on delivery requirements
99
Outbound Appointments
• Warehouse calls carrier– The preferred carrier is offered the load first– Load may be tendered to multiple carriers if the primary
carrier cannot handle the load
• No appointments from ‘drop’ trailers
100
Yard Management
• Yard provides storage for inbound and outbound trailers and sea containers
• Functions required:– Log arrivals and departures
• SCAC, trailer id, trailer contents
– Log trailers current locations and movements
101
Yard Management
• Trailer arrival (Check-in)– Verify authorization– Note trailer contents and seal (inbound)– Record arrival date/time– Record condition of the vessel– Direct driver to a dock door or yard location
• Trailer departure (Check-out)– Verify authorization to leave– Verify contents or seal (outbound)– Record departure date and time
102
Receiving
• Open a receipt– One header record with vendor identified– One or more detail records with items to be received
• Unload the trailer• Identify the product• Stage product for putaway• Close the receipt
103
Open a Receipt
• Get shipping paperwork from the driver• Determine purchase order from shipping
paperwork• Create a Receipt (paper or electronic)• Verify delivery on time• “Blind” receipts• Advanced Shipping Notice (ASN)
104
Unload the Trailer
• Count the number of packages• Compare the number of packages to the
shipping paperwork• Check for damage• Record damage or count discrepancies
(paper or electronic)• Sign the shipping paperwork• Release the driver (live load)
105
Identify Product
• Sort the product, if necessary• Build pallets• Count each item delivered• Record all product identified (paper or electronic)• Compare the count to the shipping paperwork and
purchase order• Perform any required inspection• Divert samples to the QA area
106
Stage for Putaway
• After product has been identified and is ready to be putaway
• Organized for storage• Optional step
107
Close the Receipt
• Record any discrepancies• Send the receipt to accounts payable• Manually or electronically • Freight claims for damage product
108
Putaway
• Decide whether to use product immediately (cross-dock) or store for later use
• Select a storage location• Putaway execution
109
Decide to Use or Store
• Cross-dock?– Need product for backorders?– Need product for manufacturing?– Use to fill a customer order (other than a backorder)?– Distributions to stores?
• Can product be used to top off a primary pick location (pickface)?
• Putaway to secondary storage
110
Select Storage Location
• Location selection based on:– Size of product– Quantity to store– Annual product usage (velocity)– Storage requirements (flammable, refrig...)– Lot control, date control
111
Putaway Execution
• Select product to be putaway– First received– Priority– Area serviced by a person
• Deliver to the selected storage location• Record product movement
– RF– Paper
112
Order Management
• Order source– One header record with customer identified– One or more detail records with items to be
ordered
• Special issues• Shipment planning
113
Order Source
• Source– Order entry department– Customer service or sales– Directly from customers
• Method– Phone– Fax– Electronic
114
Order Specifics
• Sold-To, Ship-To, Ship-For• Ship Date or Delivery Date Requested• Carrier• Order Type and/or Priority• Under/Over Ship Allowed• Back Order Allowed
115
Order Type / Priority
• Order type– Customer order or Store order– Transfer order– Return To vendor, Scrap, Kitting, etc.
• Priority– Rush– Regular– Will-call
116
Special Issues
• Lot control– Chemical, Pharmaceutical, Food, Clothing
• Inventory reservation• Units of measure
– Standard– Converting
117
Shipment Planning
• Determine the best way to deliver an order– When it has to be there – Carriers available– Size of order– Cost– Hazardous considerations
• Can put real pressure on the warehouse
118
Best Way to Deliver
• Types of carriers– Common (TL, LTL)– Contract– Parcel or small package (UPS, FedEx)– Air
• Cost comparison example– LTL = $100 for first 500 pounds – UPS = $5.50 plus $.50/pound up to 150 pounds
119

Picking Approaches
• Order picking• Independent picking• Cluster picking• Batch picking
– To pallet– To belt
136
Order Picking Approach
• Part or all of one order• By area of the warehouse (type, size, ...)• Pick and pass• Location selection
– Order entry system– Fixed– Operator– WMS
137
Order Picking Approach
• Process– RF– List– Labels w/ or w/o RF
• Pick sequence– Travel– Location number– Operator determined
138
Independent Picking Approach
• Individual picks without regard to order• Multiple people may pick for one order• Take advantage of equipment• Limited to an area of the warehouse• Based on priority• Usually full pallets
139
Pallet Picks
140
Pallet Picks
141
Independent Picking Approach
• RF most common• Usually only used when a WMS in place• Order integrity established in shipping• Location selection by WMS
142
Staging Area
143
Cluster Picking Approach
• Pick multiple orders at once• Pick to tote or shipping carton• Use cart or automation• Part or all of each order• Maintain order integrity• Minimize travel
144
Cluster Picking Approach
• Usually picking individual units • Usually from pickfaces• Process
– RF– List– Labels w/ or w/o RF
145
Carousel
146
Batch Picking Approach
• With Waves• Pick inventory, not orders• Pick one or more items• Optimize picking• Usually from pickfaces• Requires WMS for planning and execution• Requires sortation (equipment or person)
147
Batch Picking Approach
• Order integrity established in shipping process options:– To pallet
• RF
• List
• Labels w/ or w/o RF
– To belt• Almost always with labels
• Labels barcoded for sortation
148
Pick to Belt
149
Pick to Light
150
Wave Generation
• A wave is a collection of picks organized to improve picking efficiency– Group picks by item, not order– Use batch picking– Requires sortation
151
Wave Generation
• Wave picking is likely to be used when:– Large number of orders
• Client 1– 17,000 items, 1300 case pickfaces– 1700+ orders, 70,000 -150,000 lines per day
• Client 2– 25,000 items, 5000 case pickfaces– 10,000 orders per day
– Case or unit picks dominate orders
152
Wave vs. Order Pick Generation
• Common wave generation rules– Single trailer– Same stop across all trailers– Carrier
• Wave generation limitations– Time– Sortation or palletizer capacity– Number of dock doors
153
Sortation
• Conveyors– Powered or not– Belts and rollers most common
• Scanners• Diverters• Chutes
154
Sortation
155
Sortation
156
Merge
157
Other Picking Considerations
• Lot control– Finding– Recording
• LIFO/FIFO• Serial numbers
158
Pickface vs. Secondary Storage
• Pickface– Primary picking location for an item, assigned– Rack, flow rack, shelf, bin– Usually for product picked in less than largest
UOM (less than pallet or less than case)– Replenished from secondary storage– Make picking for orders easier and quicker
159
Pickface vs. Secondary Storage
• Secondary Storage– Random storage, here today - there tomorrow– Rack, shelf or floor (bulk) storage– Primarily for product picked in largest UOM– Secondary source for picking less than largest UOM
160
Replenishment
• Refilling a primary storage location (pickface) with product from a secondary storage location
• Methods– Min/max– Top-off– Pro-active– Demand
161
Packing Stations
• Repack (overpack) product for shipping• Some product can’t be shipped in its current
package– Too small– Fragile– Security
162
Packing Stations
• More economical to ship multiple products together in one carton– Savings in freight more than packing cost– Make sure it all arrives at once
• Kit or combo assembled for shipment (customer service)
163
Shipping Process
• Planning (discussed in last session)• Delivery to shipping, staging• Loading• Print paperwork• Check-out• Confirm shipment
164
Shipment Staging
• Designated area for each shipment, load or carrier• Pickers deliver• Final preparation for shipment
– Count verification using order or pick list– Stretch wrapping– Print and attach packing list or shipping label
165
Loading
• Reverse stop sequence• Balance trailer
– Front-back– Left-right
• Damage considerations• Hazard considerations• Security considerations• Shipper load and count• Carrier load and count• Close the trailer, seals
166
Print Paperwork
• Bills of lading• Packing list• Shipping labels• Manifest• Export
167
Bills of Lading
• Represents contract with common carrier to deliver items– Shipment (straight)– Memo/stop– Master
• Shipper assigns Bill of lading (BOL) number• Carrier assigns PRO number• Carrier signs BOL to accept load• Customer signs BOL to accept from carrier• Contents on next slide

180
Physical Inventory
• Periodic count of all inventory in the warehouse to update inventory records
• Periodically– Once or twice a year– Shut down the warehouse for 1-3 days– Slow time of year– Minimize inventory on-hand
181
Physical Inventory
• Must clean up everything and put everything away– Ship or close all orders– Complete all receipts– Empty the docks– Usually reduce operations up to a week in
advance
182
Physical Inventory
• Count– Go to a location and count what is in the location by item– Compare the results to what the inventory records show– Adjust the inventory records as required– Blind count
183
Physical Inventory
• Count (cont.)– Recount vs. original count
• Quantity
• Dollar value
• Supervisor recount
– Summary vs. detail count• 187 pallets of the 9oz size 24/case
• 187 pallets * 60 cases/pallet * 24 units/case
184
Physical Inventory
• All inventory– Wall-to-wall– Top-to-bottom
• Update inventory records– Updated at a point in time– Recognize gain or loss– Variances grow until the next physical
185
Cycle Counting
• Regularly count a prescribed portion of the inventory based on a formula to insure inventory accuracy
• Philosophy radically different from physical inventory• Regularly = daily/by shift
186
Cycle Counting
• Count - same as for physical inventory• Prescribed portion of inventory
– Certain percent of inventory each day– Plan for coverage of the entire warehouse– Balance between cost and benefit– Don’t do shipping, receiving, staging, etc.– Do storage locations, pickfaces, etc.
187
Cycle Counting
• Formula– Simple as 1 aisle per day or x locations per day– ABC cycle counting
• Frequency by item based on value and volume
• 30/90/180 days
• Applies effort to products of higher value
– Always exceptions based on the business
188
Cycle Counting
• Key issues for cycle counting– Must be statistically significant sample– Saves money!
• Reduced labor
• Reduced shipping errors
• Improves customer service
• Reduced inventory levels
– Done while the warehouse is in operation - before, during or after regular hours
189
Kitting
• Combining two, or more, finished items together to create a new finished item– Examples: gift pack, sample pack, value pack, special
offer, display pack– Combining, not changing– Finished items items are salable separately– May be inventoried or special order– De-kitting
190
Value Add Operations
• Add highly variable customer specific “things” to a product before it is shipped without changing the basic nature of the product– Brand labeling– Ticketing and tagging– Personalizing
191
