The Swap Body Vehicle Routing Problem (SBVRP) is a transportation problem on the basis of the classical vehicle routing problem with a twist: Vehicles may pull trailers, and along with them, swap bodies than can be parked and/ or exchanged (between the trailer and the main vehicle) at specific destinations. In this sense, each vehicle is able to change its configuration on a given route. Parking a swap body comes with the benefit of a reduced fuel consumption, as, obviously, the vehicle becomes lighter. However, parked swap bodies have to be picked up later, and corresponding de-tours must be driven. This results in a problem definition similar (but not identical) to well-known truck-and-trailer VRPs.

The SBVRP has been introduced in the VeRoLog Solver Challenge 2014, an implementation challenge of the EURO Working Group on Vehicle Routing and Logistics Optimization. Our approach ranked third in the competition. Follow this link to a press release by PTV Group.
