Transfreight, LLC, is a third-party logistics provider that supports Toyota Motor Manufacturing's operations in North America. As part of its logistical support, the company operates several crossdocks that facilitate Toyota's focus on lean manufacturing principles. In this paper, we describe our development of a mixed-integer linear program that provides optimal allocation of inbound trailers to docks at a crossdock facility. We focus on improving its operational efficiency and balancing the workload of the crossdock workers. We discuss Transfreight's successful implementation of our model for its inbound trailer assignments at its largest crossdock in Georgetown, Kentucky. Our work has provided Transfreight with significant cost savings and growth opportunities.
