If shipments have to be transported between many sources and sinks, direct connections from each source to each sink are often too expensive. Instead, a small number of nodes are upgraded to hubs that serve as transshipment points. All sources and si

We consider the Symmetric Quadratic Traveling Salesman Problem (SQTSP), which is a generalization of the classical TSP where each sequence of two consecutive edges in the tour gives rise to a certain cost value. For the standard linearization we appl

Hub location problems are strategic network planning problems. They formalise the challenge of mutually exchanging shipments between a large set of depots. The aim is to choose a set of hubs (out of a given set of possible hubs) and connect every dep

This paper proposes a new lower bounding procedure for the Uncapacitated Single Allocation p-Hub Median Problem based on Lagrangean relaxation. For solving the resulting Lagrangean subproblem, the given problem structure is exploited: it can be decom

Recently, a new model for the uncapacitated single allocation p-hub median problem was defined, which uses a more realistic cost structure. Instead of measuring the transport costs as a linear function of the volume, integer variables for the number

A “less than truckload” (LTL) network organises the transport of small shipping volumes by truck between given depots. To be cost-efficient it is necessary to bundle and unbundle goods on their way, using depots as so-called hubs . Our aim is to

The importance of logistics in all its variations is still increasing. New technologies emerge, new planning methods and algorithms are developed, only to face a market with a growing complexity and the need of weighting monetary costs against ecolog

We consider a complicated hub location problem which includes multi-allocation, 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 c

Hub location problems model the strategic design of transport networks for depots which mutually exchange shipments: A number of hubs is chosen from possible locations and every depot is connected to every other depot using one or two hubs in between
