Title: Minimizing earliness-tardiness costs in supplier networks – A Just-in-time Truck Routing Problem

Abstract: We consider a routing problem, where orders are transported from several suppliers to an original equipment manufacturer (OEM) by applying just-in-time principles. This implies that shipments cannot be picked up before their release date at which they are ready at the supplier and should be delivered as close as possible to their due date at the OEM. The orders – with possibly distinct due dates – are consolidated on trucks. The performance of the transportation network is optimized by finding an allocation of shipments to trucks and routes for each truck that minimize the earliness-tardiness costs. These penalties are caused by deviations between the trucks’ arrival times at the OEM and the due dates of the loaded shipments. To solve the problem, we introduce a large neighborhood search-based meta-heuristic approach in the paper. This enables finding high quality solutions also for instances with many shipments.
