We consider a complicated hub location problem which includes multiallocation, different hub sizes and different transport volumes on different week days. Furthermore, we consider transport costs per vehicle and not per volume which transforms the cost function into a step function and makes the problem numerically very hard. In our previous work we developed a heuristic approach which we now want to compare to CPLEX results for general and simplified models. Supported by Deutsche
