Abstract
In the context of Hyperconnected Logistics Network, access hubs are first-tier consolidation and transshipment points which facilitate direct transfer of parcels between unit zones via couriers. These hubs can foster resiliency by being assigned to multiple unit zones when located at their intersections. In this paper, we propose an optimization based approach leveraging modularity to design a potential access hub network that need not be implemented as designed, but rather fed into large scale network design and clustering optimization models to improve its solvability when accounting for comprehensive inter-hub flow. Then, we study the efficiency and robustness of the proposed model through a set of experiments performed with an illustrative case representative of world’s megacity inspired from a large parcel express carriers’ operation. Results indicate that we should leverage on the capability of an access hub to serve more unit zones given its capacity restrictions. Finally, we identify promising future avenues for research and innovation enabling Logistics Service Providers (LSPs) in achieving their goals of serving efficiently and sustainably while offering fast and precise delivery services
