Applying Lean Concepts in a Warehouse Operation Frank Garcia Partner ADVENT DESIGN CORPORATION
What We’ll CoverBasic Lean Concepts for WarehouseImprovementUsing Value Stream Maps:Current & Future StateImplementing Process ImprovementsCase Study Using and OngoingApplication (Pork Producer)
WHAT TO DO ABOUT THE WAREHOUSE? • Too many people • Excessive material handling • Inventory inaccuracies • Don’t ship the pounds • No space!!!! Need to Expand!
WAREHOUSE CHALLENGESFocus on Manufacturing.Warehouse is a box on theVSM Office & Info Flow Customer DemandsProduct pushed intowarehouse & pulled bycustomers WarehouseApplication of LeanPrinciples to an area thatexists because of waste inthe value stream or customer Production Suppliersdemand/lead timeWarehouse is the crossroadsof conflicting requirements
How Do We Use Lean Techniques for Warehouse Improvement?Assess the operation using a Value StreamMap and/or PFDs (Product families & Warehouse data)Involve the operators & supervisorsIdentify lean improvements & kaizens Question every activity! Treat the warehouse like a large staging areaDevelop justificationImplement lean improvements using VSMplanStart the cycle again!
Lean ManufacturingFundamental Principle of Lean Manufacturing Any activity or action which does not add value to the product is a form of waste and must be eliminated or minimized.In the Warehouse Customer Pays for Shipping Everything Else Must Be Minimized !
What Do We Need to Know? Demand Material Flow & Handling Information Flow to the Warehouse How Material is Stored Order Picking & Staging How ShippedVALUE STREAM MAPPING!
Why Use VSM?Road map for lean improvementsTrain team members in use of leanconceptsIntegrated lean implementation planLong term planning - Many Future States

Opportunity: Material Flow & Layout Many crossed flows !
Opportunity: Walking and Lifting in Palletizing Little case accumulation Case lifting and walking Pallet cycle time too long Cases missing straps Area used for order staging No visual controls
Opportunity: Rack Storage and Utilization Daily Product Aging Counts Insufficient pallet storage for peak months No rack locator system Reefers used for overflow storage Product gets lost Rely on operator memories or supervisor expediting
Opportunity: Order Picking & Shipping Order picking too slow Must pick before final order confirmation Few operators understand warehouse Dock staging too small Inventory updated at scanning Not enough dock doors
ORDER PICKING FLOW FRESH SMOKED FROZEN GET PICK GET LOAD LIST PATTERN LOCATE PALLET IN WAREHOUSE LOCATE PALLET IN DOCK RACKS • MOVE PALLET PICK• CASES 95% OF TIME CASES OR PALLETS REPEAT UNTIL • MOVE PALLET ORDER COMPLETE STORE PALLET • PALLETIZING STAGE AREA ORDER • DOCK • MOVE TO INSPECTION CHECK ORDER SCAN BAR CODES • MOVE TO TRUCK LOAD TRAILER
Opportunity: Case Flow Through Metal Detection & Strapping • No gap between cases • Cases jam at metal detector • Maintenance adjusts metal detector • Run out of strap • No system status display
Opportunity: Production Scheduling Not inSync With Shipments or Warehouse Capacity Pallet storage in aisles Insufficient pallet storage for peak months Outside Freezer Warehouse Used used for overflow storage
How Do We Fix It? Look at Application of Lean Concepts Future State Using Value Stream Maps With & Without Expansion
Future State Questions What is the takt time? Will we build to shipping or to a supermarket? Where can we use continuous flow? How do we level the pacemaker process?SUPPORTING IMPROVEMENTS What process improvements will be necessary to eliminate waste?
TAKT TimeSynchronizes pace of production to match pace of sales Rate for assembling an order based on shipping schedule TAKT = Effective Working Time per Shift Customer Requirement per Shift
Look for No Flow &Wastes They are in the warehouse too!Inventory (too much)Overproduction (more or sooner than needed)Correction (inspection and rework)Material MovementWaitingExtra MotionNon-Value Added Processing

Organizing the Lean Solutions Process Problem SolutionMetal M1. Cases not metered into machines causing jams and M1. Create space between cases with metering device increasesDetection backup of product reliability of strapper and metal detector&Strapping M2. Metal detector setting has to be changed manually M2. Scan product to set metal detection setting increases reliability of metal detector P1. Product is handled twice, once to palletize then once to P1. Rearrange high moving product to allow case stacking in flow pick racksPalletiz- P2. Operator walking several feet to obtain correct case of P2. Shorten walking distance by separating product onto shortering product to palletize conveyors P3. Product is moved to be shrink wrapped prior to put P3. *Automate the shrink wrapping process with conveyor and away automatic wrapper ST1. Searching for open position for putaway ST1. Implement W arehouse Management System for putawayStorage ST2. Product must be rotated from top to bottom resulting in ST2. Rearrange racking for whole pallet flow racks on high movingRacks and several pallet moves productStaging ST3. Need forklift to put bottom row away. Need ladder to ST3. Remove lower rail on certain aisles to allow pallet jack putaway pick from second tier. instead of forklift. Lower second tier to pick height without ladder. O1. Pickers searching for product due to no location system O1. Put pick locations on pick ticket after W arehouse ManagementOrder O2. W alking from aisle to aisle with no logical sequence of System is installedPicking picks O2. Sort products by frequency of pick then by weight in warehouse O3. Rotating stock to bring oldest date to front to minimize walking O3. *Use pallet flow racks to automatically rotate stockShipping SH1. Insufficient space to stage multiple pallets leads to SH1. *Increase floor space for dock staging. Long term plan would be double moves of product to reorganize when building is expanded SH2. Operator is dedicated to verifying picked pallet prior to SH2. Improve picking operation through training and scanning at pick scan location with bar code scanners. SH3. Occasionally additional product gets shipped to SH3. Confirmation check by scanning once prior to loading truck customer

PROPOSED IMPLEMENTATION PLANWithout Expansion Phase 1. Simple modifications 1. Remove bottom rail to allow pallet jack access. (Target date May 2003) 2. Lower second tier to remove the need for ladder access. (May 2003) 3. Match shelf size with average pallet height to increase the number of pick locations. (May 2003) 4. Change speed of conveyor in metal detection room to space product cases properly or implement as part of palletizing relocation. (May 2003) 5. Balance flow of orders transferring from the order pickers to verifiers during the entire shift. This can be accomplished by training more utility operators as outlined in the organizational restructuring matrix shown in Section 4. (May 2003) 6. Label all pallet rack storage locations to begin transition to warehouse management system(May 2003) 7. Place 135 high moving SKU’s on first or second tier of the pallet rack. (May 2003)
PROPOSED IMPLEMENTATION PLANWithout Expansion Phase 2. Moderate improvements to computer system and operations 1. Implement warehouse wide standards on order accuracy, line items shipped on time, orders shipped complete. Post the results weekly to begin continuous improvement philosophy in warehouse activity.(June 2003) 2. Install static racking above the existing palletizing area, leaving sufficient head room for the palletizing operation. (September 2003) 3. Install new vertical recirculation conveyor palletizing station and lift tables. (September 2003) 4. Consider implementation of CSB locator screen using move tickets if automated scanning will be delayed. (September 2003) 5. Install flow through pallet rack on bottom tiers of existing racks to eliminate top-down pallet rotation on high movers. (October 2003) 6. Change configuration of metal detection conveyor to scan labels prior to entering metal detection equipment. Use barcode scan to change settings on the metal detector. (2004) Phase 3. Major improvements to computer system and operations 1. Upgrade CSB system to include Warehouse Management System for locating product and install equipment to bar code scan case labels. (1 st quarter 2004)

What Happens in the Future State VSM With Expansion? Expand warehouse to provide staging areas Most pallets are staged on floor not in racks Revised order picking methods…Pick from pallets not racks Robotic palletizing system based on previously upgraded system Improved production scheduling & planning New markets for frozen products to increase turns
