Abstract
Through observations from real life hub networks, we introduce the multimodal hub location and hub
network design problem. We approach the hub location problem from a network design perspective. In
addition to the location and allocation decisions, we also study the decision on how the hub networks
with different possible transportation modes must be designed. In this multimodal hub location and
hub network design problem, we jointly consider transportation costs and travel times, which are
studied separately in most hub location problems presented in the literature. We allow different
transportation modes between hubs and different types of service time promises between origin–
destination pairs while designing the hub network in the multimodal problem. We first propose a linear
mixed integer programming model for this problem and then derive variants of the problem that might
arise in certain applications. The models are enhanced via a set of effective valid inequalities and an
efficient heuristic is developed. Computational analyses are presented on the various instances from the
Turkish network and CAB data set.
