| Abstract: | The exchange of cargo capacities is a well established approach in logistics. However, only few logistics marketplaces are
able to take into consideration synergies that can be generated by combining different transportation routes of different
logistics carrierps. In order to exploit these synergies, we designed and implemented the combinatorial exchange mechanism
ComEx for the intra-enterprise exchange of delivery orders in a logistics company organized in a profit center structure. Each
profit center is able to release delivery orders to an adjacent profit center if the geographic locations of the customers
allow for a reduced-cost delivery by the adjacent profit center. We demonstrate that by using the ComEx mechanism, the total cost of transportation of our logistics company can be reduced by up to 14%. Since our iterative auction
mechanism is very complex and therefore resource-intensive, we reduce the complexity by applying a convex hull approach combined
with a distance-based cost estimator.
