2 Agenda Introduction 1999 Environment Solution Approach Network Design
Implement New Strategy Results to Date Summary

3 Introduction

4 Objectives/Motivation
Importance of Pipeline Inventory Pipeline Inventory and Network Design Role of modeling Information in variables Stronger formulation Financial impact

5 The Need for Speed Financial Incentives: Capital Utilization In 1996
Ford produced 3.9 million vehicles in the US In 2008 they produced 2.3 million Avg. transit time 15+ days Avg. vehicle revenue $18,000 Value of pipeline inventory: > $2.8 Billion One day reduced transit time: $190 Million reduction in pipeline inv. 1,400 fewer railcars

6 The Need for Speed Demand for land 22 Plants 54 Destination Ramps
~1,200 Load lanes ~8,400 vehicles waiting at plants $166 Million in inventory

7 The Need for Speed Other Incentives Damage Flexibility Others?

10 The Price Inventory at the cross dock Added distance traveled
Handling at the cross dock Capital costs of the cross dock

11 Mixing Centers

12 1999 environment

13 1999 Vehicle Network Delivery Conditions
Record production levels Demand shift from cars to trucks Overburdened rail infrastructure Deteriorating rail service Shortage of transport capacity Mixing centers 15+ day transit time High inventory cost Dissatisfied customers

14 High 1999 Level Statistics Assembly plants 22 Mixing centers 5
Destination rail ramps 54 Dealer locations 6,000 Production volume Mil./Year Freight expense $1.5 Bil. Dec. ‘99 avg. transit time Days Pipeline Inventory $4.1 Bil.

15 Ford Distribution Network
Mixing Center Origin Plant Groupings Destination Ramp Planned Ramp Closure Edison Norfolk Atlanta Kentucky Ohio St Louis Canada St Paul Michigan Chicago Kansas City 15% of all vehicles go Haulaway Direct to Dealer within Miles of the Assembly Plant 85% of all Vehicles go via Rail to a Hub (Mixing Center or Destination Ramp)

16 Old Delivery Design Push Network
Vendor sub systems optimized for individual segments Little to no visibility Mixing Centers not used effectively

17 solution approach

18 Ford Goals Speed 1999: Average 15 days transit time
Goal: Maximum of 8 days transit time Precision 1998/1999: 37% on time within 1 week Goal: 95% on time within 1 day Visibility 100 % Internet vehicle tracking from plant release to dealer delivery Guide the flow of vehicles Respond to variations Inform customers

19 network design

20 Design Process Truck vs Rail delivery Allocate Dealers (FIPS) to Ramps
Route Flows through Rail Network

21 Ford Locations Plant Mixing Center Origin Ramp Dest. Ramp MC Ramp
This is the Ford Network. The lavender triangles represent the plants Light blue squares are the current mixing centers. Green and Red Diamonds represent origin and destination ramps respectively. The yellow stars are Ford Dealerships. Plant Mixing Center Origin Ramp Dest. Ramp MC Ramp

22 An Allocation Model

23 Single-Sourcing Allocation
Var Assign{FIPS, RAMPS} binary; Minimize TotalCost: sum{fip in FIPS,ramp in RAMPS} Cost[fip,ramp]*Assign[fip,ramp]; s.t. SingleSource{fip in FIPS}: sum{ramp in RAMPS}Assign[fip,ramp] = 1; s.t. ObserveCapacity{ramp in RAMPS}: sum{fip in FIPS} Volume[fip]*Assign[fip,ramp] <= Capacity[ramp];

24 Old Ramp Allocation Southern US
Dealers sourced by multiple ramps Under the old system dealerships could be fed from multiple destination ramps. This proved to be costly and more difficult to manage.

25 New Ramp Allocation Southern US
As you can see the new design is much cleaner and eliminates the delivery overlap from various ramps. Dealers sourced by single ramps

26 New Allocation of Dealers to Ramps Mainland US
This is how the entire U.S. looks. Again, no overlapping areas.

27 Flows through the Rail Network
Objective is NOT Freight cost!

28 The Objective IS Speed Capital Land

29 The Promise Speed Unit trains bypass hump yards

30 The Promise Capital & Land Laurel, Montana Orilla, Washington Time

31 Capital & Land The Promise 22 Plants 54 Destination Ramps
~1,200 Load lanes ~8,400 vehicles waiting at plants $166 Million in inventory Each Plant to One Mixing Center ~22 Load lanes ~154 vehicles waiting at plants ~$3 Million in inventory

32 The Price Inventory at the cross dock Handling at the cross dock
Capital costs of the cross dock Added distance traveled

33 Making the Trade-offs Measuring Inventory In the rail network
At the plants and Cross Docks Load-driven system Railcars depart when full Relationship between Network Design and Inventory

34 Inventory at the Plants
Half a rail car full for each destination Laurel, Montana Orilla, Washington Time

35 Inventory at the Mixing Centers
Half a rail car full for each destination Laurel, Montana Orilla, Washington Time

36 Workload at the Mixing Centers
Unpredictable Rail car holds 5 vehicles Orilla Benicia Mira Loma Laurel Denver Orilla Benicia Mira L. Laurel Denver

37 Workload at the Mixing Centers
Balanced: Only load cars you empty Rail car holds 5 vehicles Orilla Benicia Mira Loma Laurel Denver Orilla Orilla Benicia Mira L. Laurel Denver

38 Effect on Inventory Inventory at Mixing Center slowly grows
to just over (ramps -1)(capacity -1) and remains there Roughly twice the inventory of before Still depends on the number of ramps the cross dock serves Why this number?

39 Consolidation for Speed
Unit Trains of rail cars don’t stop at mixing yards Trade moving inventory for stationary inventory

40 Model Paths Demand[ramp, plant] Variables: Route from Plant to Ramp
Mode used on each edge Demand[ramp, plant] Combined demand at ramp for all products from the plant Variables: PathFlow[path]: Volume from the plant to the ramp on the path UseLane[fromloc, toloc, mode] binary Did we use the mode between two locations

41 Model Objective Minimize the number of vehicles in the pipeline
Moving Component (Transit times) Waiting Component (Mode Size) Minimize PipelineInventory: sum{path in Paths} (Total Transit Time)*PathFlow[path]; sum{(f,t,m)} (Size[m]/2)*UseLane[f,t,m]

42 Model Satisfy Demand The sum of flows on all paths between a plant and a ramp must meet demand s.t. SatisfyDemand[p in PLANTS, r in RAMPS}: sum{path in PATHS: Plant[path]=p and Ramp[path] = r} PathFlow[path] >= Demand[p,r];

43 Model Define UseLane For each pair of locations and mode between them write a constraint for each plant and ramp s.t. DefineUseLane[p in PLANTS, r in RAMPS, (f,t,m) in EDGES}: sum{path in PATHS: Plant[path]=p and Ramp[path] = r and (f,t,m) in PATHEDGES[path]} PathFlow[path] <= Demand[p,r]*UseLane[f,t,m];

44 Model Large Model Lots of Variables: Many Paths
Lots of Constraints: DefineUseLane The LP relaxation is nearly always integral Use Column Generation

45 Reduced plant destinations
New Rail Lanes The model concentrated allocated volume in fewer lanes reducing the amount of destinations built by each plant. Reduced plant destinations

46 Final Outbound Rail Network with Carriers
St Paul Canada Edison Michigan Chicago Ohio St Louis Kentucky Norfolk Kansas City Atlanta Mixing Centers Destination Ramps Union Pacific CSXT FEC BNSF Canadian Pacific Car Haul to Ramp Norfolk Southern Canadian National

47 results to date

48 Results Cut vehicle transit time by 26% or 4 days
$1 billion savings in vehicle inventory $125 million savings in inventory carrying costs Avoid bottlenecks Reduce assets in supply chain Improved inventory turns at dealer

49 Benefits Ford Dealers Rail Carriers Auto Haulers
While we have touched upon the benefits, let’s review them in greater detail. There are 5 primary beneficiaries that we will address.

50 Benefits - Ford On-time delivery Competitive edge Cost control
1. The Autogistics network supports the “On Time Delivery” initiative and increases its chances for success. 2. For the first time the supply chain can be accurately analyzed by segment and activity. Core problems can be analyzed and solved in less time and with much greater accuracy. The potential for reducing system variation is a reality. 3. The manufacturer that can produce a reliable finished goods network can obtain a competitive edge in multiple ways. Increase customer satisfaction Reduce the total cost of a vehicle for manufacturer and dealer 4. Allows Ford a single source for finished vehicle logistics. 5. Car Trackers ability to measure and produce reports improves accountability throughout the supply chain and eliminates the continuous finger pointing. Key to successful systems of any type is an accurate feedback loop. That is now in place. More importantly, it allows more time to be expended solving the problem. 6. Where does this improve the cost picture? Shortened supply chain reduces the amount of assets in the chain and reduces the inventory carrying cost. A shortened and reliable chain will increase the potential for custom orders and internet orders and reduce build for inventory. Also stops additional expense of shipping diversions due to equipment shortages.

51 Ford Motor Company Closing Share Price 2000 - 2001
A Bit of History Ford reports record earnings of $7.2 billion in 1999 Ford Motor Company Closing Share Price Ford sets all-time monthly U.S. sales record Firestone recalls tires after roll-over deaths Cut 5 days out of total inventories freeing $1.8 billion in capital Jacques Nasser appears before a Senate on Firestone tire recall Standard & Poor's cut debt ratings to junk status Jac Nasser retires as CEO of Ford Motor Company Ford Motor Company and UPS Logistics Group form Autogistics Cut 26% off vehicle delivery times releasing $1 billion from inventories

52 Benefits - Dealers Reduced inventories Increased customer satisfaction
Inventories are maintained to provide cars for the buying public. When the source is not reliable higher inventories are maintained to ensure that stock is available and sales are not lost. The improved visibility and precision in the network allows a leaner inventory while not sacrificing sales. The ability to provide a customer an arrival date and meet that date enhances the buying experience thus increasing customer satisfaction Dealerships will be better able to plan car preparation functions due information on Car Tracker.

53 Benefits - Rail Carriers
Improved equipment utilization (reduced capital expenditures) Visibility and planning capabilities Synergies with existing UPS traffic Increased cooperation 1. If velocity of the inventory increases, as it will, then the automotive rail cars will more quickly travel through the system. Reducing the amount of equipment needed will decrease the amount of future capital expenditures. 2. Using Car Tracker will enable the rail carriers to better plan and respond to the needs of Ford. 3. By combining existing UPS intermodal traffic with automotive traffic more dedicated trains can be created easing scheduling of crews and equipment. 4. The improved visibility promotes cooperation between the carriers.

54 Benefits - Auto Haulers
Expanded dealer delivery hours Visibility and planning capability Improved asset utilization Increased cooperation 1. Allows haulers to reduce equipment and maintain lot sizes. 2. Haulers will no longer have to respond with no notice. 3. Without having to deliver in a narrow window the car hauler can run multiple shifts and use the same equipment. Knowledge of what is in the supply chain enables them to increase routing effectiveness. 4. The system is no stronger than the weakest link. Getting away from optimizing sub systems through Car Tracker will force cooperation.
