Urban logistics systems play an important role in the economic growth and prosperity of today’s cities. Current delivery practices though have proven problematic and to be causing various negative effects. This paper proposes an alternative method for delivering cargo, mainly parcel shipments, with the establishment of a network of small logistics hubs. The products are transported from a main logistics facility to the hubs using a fleet of trucks, unloaded, and delivered to the final destinations using handcarts or self picked-up. The authors develop a novel mathematical framework for the capacitated facility location-allocation problem, with constraints related to delivery deadlines, maximum node allocation range and number of customers allocated in each hub, and effectively solve it using CPLEX. Numerical examples and a sensitivity analysis provide evidence of the robustness of the model and its ability to effectively be applied to address real problems. The proposed approach can help alleviate traffic congestion, migrate environmental impacts and improve freight mobility in urban congested areas.
