Concave Cost per unit decreasing So? ! Shipment Size 29 29
Consolidation • Incentive to consolidate shipments – Make fewer larger shipments – Reduce frequency (!? ) – Hub & Spoke – Share transportation resources –… 30 30
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 31 31
Estimating Rates Cost of Average shipment Average Cost of shipment Large shipments Small shipments Average shipment Size 32 32
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 33 33
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 34 34
Summary • • Transportation mode basics Transportation rate basics Economies of scale promote consolidation Cautions on “aggregating” transportation rates 35 35
