Traditional Business Strategies
• Lean Manufacturing
• Outsourcing and offshoring
• JIT
• Quick and frequent deliveries
These strategies are based on assumptions of • Cheap oil price• Low labor cost in developing countries

US Diesel and Crude Oil Prices over time

Relationship between Crude Oil price and Diesel Fuel Price
Trend Line Model
Diesel Retail Price(Cents per Gallon) = 2.38515*Crude Oil Price($/barrel) + 132.292
7
Implications on crude oil price to transportation rates
• Given the relationship in the previous slide, we see that a $10/barrel increase in crude oil will result in ~$0.24/gallon increase in diesel fuel
• Standard fuel surcharge methodology is to increase surcharge $0.01/mile for every $0.06 increase in diesel fuel
• We conclude that for every $10 increase per barrel of crude oil price, we have an additional $0.04/mile increase in transportation rates.
Crude Oil ($/Barrel) 75 100 125 150 175 200TL ($/Mile) 1.65 1.75 1.85 1.95 2.05 2.15Increase (%) 0 6% 12% 18% 24% 30%

Impact of Oil Price on Network Strategy
• Trading off oil price for… Inventory costs
Facility costs
Manufacturing costs
• Manufacturer of consumer packaged goods
• Manufacturing is possible in three locations:
Philadelphia- Highest production cost
Omaha-
Juarez, Mexico- Lowest production cost
• 60 potential DC locations
• 888 aggregated customers
• Inbound transportation uses commercial TL carriers
TL averages 40,000 lbs/shipment
• Outbound transportation uses a private fleet
Private fleet averages 20,000 lbs/shipment11
Case Study 1: Oil Prices and the Logistics Network
Case Study - Objectives
• Determine the best number and location of distribution centers, as well assignment of customers to DC’s.
• Determine the best allocation of production to their manufacturing locations.
• Understand how the optimal network would change as oil prices fluctuate Roughly 25% of the supply chain costs are in transportation

Network Visualization
Discussion of Tradeoffs
• As crude oil price increases, transportation costs become more important relative to production, inventory and facility fixed costs.
• Oil price vs. inventory carrying and facility costs Additional DCs are more attractive
As outbound transportation becomes more expensive, it becomes increasing important to minimize the distance of the final leg.
• Oil price vs. production costs Production moves nearer to demand
Cheaper manufacturing in Mexico is offset by higher transportation costs.
14
Oil price vs. inventory carrying and facility costs
Moving from $125/ barrel to $150/ barrel changes the optimal number of DC’s from 5 to 7. In particular, you can think of Las Vegas being replaced by Los Angeles, Albuquerque, and
Portland.$75/ barrel $200/ barrel
15
The Tipping Point
Oil price vs. production costs
$75/ barrel $200/ barrel
16
Total Cost Comparison
3% increase in total cost
as the price of a barrel
increases from $100 to $150

Impact of Oil Price on…
• Transportation Costs
• Network Strategies
• Transportation Strategies
• Supply Chain Strategies
Changes in Transportation Strategy
• From JIT delivery to better utilization of transportation capacity Larger lot sizes shipped less frequently Efficient packaging to improve truck utilization
• From quick delivery to cheaper and sometimes slower transportation modes From air to ground From trucking to rail
• From dedicated to shared resources 3rd party carriers Consolidated warehouses

Changes in transportation strategy: Examples
• In 2007, S.C. Johnson’ truck utilization project saved the firm “$1.6 million and cut fuel use by 168,000 gallons.” The firm found that mixing loads of Winded glass cleaner and
Ziploc bag, which used to be packed in separate loads, better utilizes truck capacity
• Multiple manufacturers store their products in ES3’ giant warehouse located in York Pennsylvania where truck loads are built and shipped to retailer’s distribution centers. An important benefit of the consolidated warehouse is
reduction in transportation costs

Impact of Oil Price on…
• Transportation Costs
• Network Strategies
• Transportation Strategies
• Supply Chain Strategies
Changes in Supply Chain Strategy
• More Inventory Due to EOS and more DCs
• Emphasize on better service To reduce expediting costs
• Less offshoring To reduce total landed costs

Sharp moves from offshoring to nearshoring
• TV manufacturer Sharp has recently started moving manufacturing facilities from Asia to Mexico to serve customers in North and South America.
• This is driven by the need to keep shipping costs low and time to market short. Indeed, price of flat TV typically falls fast and thus reducing
shipping time from about 40 days, when flat TVs were produced in Asia, to seven days makes a big impact on bottom line.

Toy manufacturer is moving plants near demand
• Steiff, a privately owned German manufacturing company of toys was part of the global outsourcing trend when it moved around 20% of production to low cost countries. The objective was to cut cost and compete on price.
• Recently, this toy manufacturer started moving production back to Germany, Portugal and Tunisia. The reasons: quality problems together with high
transportation costs associated with manufacturing far from the key markets
26
Drivers of Moving from Offshoring to Inshoring
• Oil Price
• Labor Cost
• The value of the dollar

Challenge
Understand how increasing labor and transportation costs
across the globe are causing previous sourcing decisions to
be altered
Sourcing Parameters
37,000 SKUs
Large range of Production Costs $0.01 to $300 per unit if production is in the US
Large Range of Weights 0.01 to 5,000 pounds per unit
Manufacturing options US –Atlanta; Mexico – Monterey; China- Shanghai
Combination of transport modes Ocean; Rail; Truck Load

Costs increase between 2003 & 2008
• Labor Costs US ↑ 15 % Mexico ↑ 23 % China ↑ 144 %
• Transportation Costs Ocean Freight ↑ 100 % TL/Rail ↑ 25 %
Good estimate of the increase in rail and TL costs Conservative estimate of the increase in ocean costs
