3939
Consolidation
• Incentive to consolidate shipments– Make fewer larger shipments– Reduce frequency (!?)– Hub & Spoke– Share transportation resources– …
![Page 40: 1 1 Transportation & Supply Chain Systems John H. Vande Vate Spring 2008.](https://reader030.fdocuments.net/reader030/viewer/2022032612/56649e925503460f94b97a15/html5/thumbnails/40.jpg)

Issues with Freight Rates
• Issue of how to estimate rates on lanes you don’t currently use
• Levels of detail– $/mile as the crow flies– $/mile on the network– Rate look up
• Caution: Average cost of shipments can be smaller than the cost of an average shipment
![Page 41: 1 1 Transportation & Supply Chain Systems John H. Vande Vate Spring 2008.](https://reader030.fdocuments.net/reader030/viewer/2022032612/56649e925503460f94b97a15/html5/thumbnails/41.jpg)

Why It Matters?
• Estimating transportation costs to “customers”– Typically too many customers– Aggregate them
• By region
• By state
• By 3-digit zip
– Use some care in estimating the transportation cost to “aggregated” customers
![Page 43: 1 1 Transportation & Supply Chain Systems John H. Vande Vate Spring 2008.](https://reader030.fdocuments.net/reader030/viewer/2022032612/56649e925503460f94b97a15/html5/thumbnails/43.jpg)
4343
Why It Matters?
• Customers may order different quantities at different times
• Estimating the cost to serve the customer often look at average shipments
• Careful how you average
![Page 44: 1 1 Transportation & Supply Chain Systems John H. Vande Vate Spring 2008.](https://reader030.fdocuments.net/reader030/viewer/2022032612/56649e925503460f94b97a15/html5/thumbnails/44.jpg)

Summary
• Transportation mode basics
• Transportation rate basics
• Economies of scale promote consolidation
• Cautions on “aggregating” transportation rates
