II. Results

III. Discussion

IV. Summary

V. Recommendations

Planned Sales by Dealership 2009



► Project Goals

► Develop Greenfield approach from

port to dealer

► Evaluate current logistics network

► Evaluate synergies between

Porsche Logistics and Audi

► Develop concept on how to

differentiate between sold vs. stock

orders

► Evaluate logistics network with

target growth

Porsche

II. Results – Add Porsche to the differentiated Audi Supply Chain

Include Porsche volumes,

time focus for Porsche,

sold + high value Audis


Key Differences

► Current

► Not a direct comparison

► Differentiated is more appropriate

► Add Porsche

► Opens Baltimore , Los Angeles,

Miami, San Francisco, Newark

► Closes Davisville, San Diego

III. Discussion – Assumptions

► Linear time and cost assumption

► Context: VW Network

► Inventory of 5 cars per rail lane usage

► Fixed opening cost for ports

► Times

► Port: 4 days (target of AoA)

► Railhead: 1 day

► Vessel: provided by AoA (VW vessels)

► Rail: Union Pacific + 2 days

► Trucking: distance / 500 miles

► Costs

► Avg. Audi Values: $ X / Y

► Avg. Porsche Value: $ Z

► Inventory holding costs: 5%

► Opening ports: $ P

► Transportation costs provided by AoASource: http://www.adcet.edu.au/


Considered Supply Chain Facilities for Greenfield Approach


Approach: Multiple Flow Model (AMPL)

► Choice of potential ports and railheads

► 4 “types“ of cars modeled separately:

► Audi‘s: Stock order / Sold order / High

Value

► Porsche

► Difference: different average values and

the option to focus on speed (by pure

trucking from east-/gulfcoast)

► Minimum # of cars per year to use a port

or a rail lane

► Objective: Minimize cost

(inventory + transport)

► Optional constraints (e.g. use certain #

of ports, focus on speed for certain type

of cars by trucking,..)

V. Recommendations

► Implementation

► Fast delivery of non-stock orders: 6% cost saving with 4 days delivery savings

► Change railheads: Serve Chicago via East coast port

► Due to low sensitivity over 3-6 ports: Brunswick to Miami (stay at 4 ports)

► Minimal impact of Porsche on Audi network: Assess savings on Porsche network

► Change current model assumptions for Growth model

► Non-linear increase in transportation costs under current assumptions

► Take advantage of concave costs & time

► Consider influence of VW in more detail

► Scale of synergies, e.g. share fixed costs, share trains, concave costs and time

► Possible disadvantages, e.g. choice of ports maybe optimal for VW but not for Audi
