Presentation Outline • Background • Purpose and scope • Methods and results • Recommendations
Purpose and Scope Revise an existing capacity plan for the network of AWOHi distribution centers in each of the US region, Mexico region, and US-Mexico combined region: • Locations and capacities of existing and new DCs • Implications for existing and new DCs in throughput, inventories, storage, and service regions • Transit times • Costs • Network inventories • Returns on investment from capacity expansions
How Can We Improve the Supply Chain Management? Goal: To deliver the right product to the right place at the right time for the right price, while minimizing system-wide costs and satisfying service requirements. (Source: Ron Askin, PASI, 2013)
Can the US Dist. Network Handle Growth? • Capacity: 6,190 Stores • 2012 Store Count: 4,617 • 2018 Store Count: 5,661 YES!
Methodology • A Optimization/Heuristic Algorithm to allocate DCs to Stores and determine tour lengths • Assign stores to DCs • Assignment Optimization Problem (solved with CPLEX) • Generate vehicle routing tours • 4 Stops/Tour • Nearest neighbor heuristic • Local search algorithm • Use dual values of Assignment Problem
Assignment/Tour Results 11 DCs 10 DCs Euclidean Results Rectilinear Results 9 DCs
Store Assignments • Opening DCs in Oregon & Florida
Store Assignments • Opening Oregon, Florida, North Carolina and closing Georgia
DC Distance to Store Distribution Average Distance: 197.02 miles St. Dev: 167.81 miles
DC-to-Store Distances Average Distance: 197 miles Standard Deviation: 167 miles Upon Initial Analysis: Open DCs in Oregon & Florida by 2018
How Should Imports be Handled? • 2012 • Each DC receives ~371 import truckloads per year in full FEUs • 2018 • Number of stores expected to increase by 22% • Fraction of imports will increase from 5% to 12% • Each DC will receive ~1,085 import truckloads per year in full FEUs Almost 3-fold increase in volume of imports by 2018 Should we add one or more Import DCs?
Import DCs • Operations • Unload shipping containers • Often re-palletize products • Ship pallets to DCs • Location • Usually near container ports or inland ports • “Lumpy” demand • Shipments are large and relatively infrequent • Layout/Design • Large pallet storage areas • Large drop yards for container storage • One Import DC may serve many DCs • Can be combined with order fulfillment in one facility (current situation in case study)

Should we have Import DCs? • Advantages • Reduced overseas transportation costs • More efficient management of inventory and product flow • Lower overall inventory levels • Reduced operating costs, space usage at DCs • Disadvantages • Capital investment and fixed costs of opening a new facility • Increased transportation/handling cost to supply DCs
Should we have Import DCs? • Do we have sufficient volume to justify a dedicated facility? • Almost 3-fold increase in import volume, avg = 3 containers/day • 10 DCs • Benchmarking • Target: 1,788 US stores, ~30 DCs, 4 Import DCs* • Walmart: 4,500+ stores, 158 DCs (42 regional DCs), 5 Import DCs** • How many Import DCs? • One: West Coast • Two: West and East Coast • Four: West, Gulf and East Coasts, Mexico • Impact of multiple Import DCs • Reduced transportation costs to supply DCs • Reduced risk from natural disasters, labor strikes, etc.
How to Improve Warehouse Operations? • “SKU proliferation causing issues within the DC in terms of slotting and inventory carrying” • Investigation needed • Review of inventory management system to eliminate wasted storage capacity and obsolete SKUs • Address WH layout and operations – particularly for new DCs • DC-to-Store • Pallets • Cases • Pieces
Warehouse Layout and Operations • Reserve area • High storage density • Forward area • Fast-moving items (0, 1 or all rule) • Picking activities • Pick-to-light • Pick-to-voice • Bucket-brigades • Technology exploration • Person-to-goods • Goods-to-person
How to Respond to Growth in Mexico? • 330 retail stores • US and imported products enter Mexico through Laredo, TX • DC in Monterrey, with capacity of 360 stores • Crossdocks located in Mexicali, Mexico City (transfer operation) and serviced from Monterrey
Expected Growth in Mexico • Growth of 196 stores • 150 in Mexico (113 in Mexico City) • 46 in Central America
Estimated Increase in Transp Costs Assuming $1.23/kilometer and current network
Is Current Capacity Sufficient? • No! • Either increase capacity of current system or add DC
Is Current Capacity Sufficient? • Currently the crossdock has very limited storage capacity • Locating a DC in Mexico City seems desirable +113 Stores +46 Stores
Recommendations • Open a DC in Mexico City • Increase responsiveness to stores • Closer to Central America to service 46 new stores • Reallocate Southern Mexican stores from Monterrey to DC in Mexico City
Changes to Monterrey DC • Continue to serve 40 stores via Mexicali crossdock • Re-evaluate the stores served directly and allocate to Mexico City DC • Incur a net reduction in capacity and size
Integration of US/Mexico Supply Chains? • Slow-downs at border crossings • Although there are 3PL companies who provide distribution services for cross-border replenishment • http://www.joc.com/exel-builds-new-distribution-center-support-usmexico-cross-border-supply-chains-laredo-texas • http://www.inboundlogistics.com/cms/article/us-mexico-trade-two-way-traffic/
Return on Investment (cont.) Bottom-Line for Expansion Plan: An investment of $11 million over one year in an additional DC would deliver net present value of over $29 million in cumulative net benefits, an ROI (calculated as net benefits/total costs) of 280% (for every dollar spent on the new DC, the AWOHi will receive their original $1 back, and an additional $2.80 in incremental benefits), with five-year horizon (including 12 months of development, construction, systems integration and deployment). Payback period is approximately one year after the 12-month construction phase.
Risk Management What are the effects of uncertainties on the performance objectives of the DCs network, and what can be done?
Recommendations • Proceed with the construction of a new Florida DC in one year with 400,000 sf • Proceed with construction of a new pacific northwest DC in two years with 300,000 sf • Monitor to assure DC-to-store travel times by 5% overall • Re-integrate the import DCs to realize 20% savings on transoceanic transportation • Reconfigure the DC-to-store network including to double the tour lengths from four to eight stores and gain 10% savings in transportation • Continue to realize DC network efficiency gains through advanced technologies including RFID and warehouse-science efficiencies, “shrinking the distribution chain”
Recommendations (cont.) • Adapt the DC network continuously with attention to reducing transportation, inventory, labor, and facility costs toward growing customer value and ROI on incremental investments • Track the actual growths, throughputs, inventories, etc., relative to the forecasts of 22% growth to 2018 • Realize additional savings through lease agreements and labor-sharing agreements with other shippers • Continue to emphasize a quality metrics program for the DC-to-store network to identify anomalies and reduce variance through adjusting tour lengths, DC-to-store relationships, etc. • Continue to realize efficiencies through integrating the Mexico and US networks in vendor-to-DC transportation with import DCs, freight forwarders etc. • Add 50% capacity to the existing Mexico DC to address the new 46 stores, and monitor the situation for additional DCs into the future past the 2018 horizon

AWOHi gets bigger-- Network of distribution centers addresses 22% growth to 2018 i H W O A
Issues we need to address • Growth in number of stores, allocation of stores to DCs • SKU proliferation causing issues within the DC in terms of slotting and inventory carrying • Address with WH layout and operations • Highly skewed demand implies a need for both reserve and forward areas • Technology be employed to increase throughput • Growth in imported products • “Competition migrating to highly responsive supply chain” • Implies more DCs, not fewer? • More frequent trips to retail stores? Investigate routes with > 4 stores per route, but more frequent? How would this impact configuration of network? • Develop online sales and start doing order fulfillment at DCs? • Increasing fuel costs
Make sure these issues are addressed… • Given the migration to incremental import product • How will inventory be impacted if current direct to DC approach is continued • What alternative import methodologies should be considered • For each methodology considered, determine the: • impact to inventory • impact to facility costs • impact to freight • impact to store service
Make sure these issues are addressed… • Determine if the current DC network is appropriate given the future store growth, DC capacities, increasing fuel costs • If additional DCs are needed, determine the: • appropriate location and relative size of each additional DC • impact on the current DCs throughput, inventory, and service area • impact to DC to store freight • impact to transit time to stores • impact to DC costs (fixed and variable) • the impact to network inventory • if the changes to the network financially justified based on a reasonable return-on-investment (ROI)
