Abstract

We study the complexity of price-collecting variants of the well-known hub-location problem, in part with vehicle based costs. Due to the complexity of classical hub location problems, most of the variants are also NP-hard. So we also investigate variants when the hubs and the allocations are given in advance. It is interesting to see, that here the complexity differs depending on how the costs for the transport arise. The problem with linear costs lies in P, while some variants with vehicle based costs are NP-hard in the strong sense.
