Includes bibliographical references (leaf 53).
We explore the use of transportation relays, a somewhat unconventional transportation operations concept, in terms of improving private fleet management. A transportation relay is a shipment that is divided into two legs. With transportation relays, there is more ways to route freight with a private fleet. We use a linear program to find private fleet tours with and without relays for a large retailer. We find that relays increase private fleet use by 17% and reduce total transportation cost by 6%. Inbound relays increase the utilization of private fleet on the inbound lanes while outbound relays shift the private fleet capacity between neighboring DCs. Together, inbound and outbound relays better utilize existing private fleet resources and can be used to justify an investment in a larger private fleet through the purchase of addition tractors and trailers.
