hub location; hub location problem; numerical analysis

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.
