The Evolution of Logistics Hubs and a Conceptual Framework for Logistics Hubs Location Decisions
نویسنده
چکیده
Hubs are special centers that used for switching, transferring and handling freight or passengers in transportation systems. The hub location problem deals with locating hub facilities and allocating demand nodes to hubs in order to route the traffic between origin–destination pairs. Aiming at minimizing the total costs, maximizing utilization of transporters, maximizing the service level, etc., the flow between O–D pairs is dispatched through some selected intermediate logistics centers (called hub nodes) and links connecting the hubs. In this work, a conceptual framework is proposed for hub location decision problem in transportation networks since the previous reviews are out of date. Several models, methods and decision tools are evaluated. Also future trends are added to represent a new point of view for global scale. Since the models and solution approaches are complicated, it is not practical to catch optimum results, and some relevant algorithms will be represented to solve hub models in this chapter.

Multi-commodity Multimodal Splittable Logistics Hub Location Problem with Stochastic Demands
This study presents a multimodal hub location problem which has the capability to split commodities by limited-capacity hubs and transportation systems, based on the assumption that demands are stochastic for multi-commodity network flows. In the real world cases, demands are random over the planning horizon and those which are partially fulfilled, are lost. Thus, the present study handles dema...

Hubs are critical elements of transportation networks. Location of hubs and allocation of demands to them are of high importance in the network design. The most important purpose of these models is to minimize the cost, but path reliability is also another important factor which can influence the location of hubs. In this paper, we propose a P-center hub location model with full interconnection...

In this paper we consider a capacitated single allocation p-hub median problem with multiple capacity levels (CSApHMPMC) in which the decisions are to determine the location of p hubs and their capacity levels, the single allocation of non-hub nodes to hubs in the logistics network. This problem is formulated as an integer programming model with the objective of minimizing the sum of total tran...
