Consistent routing for local same-day delivery via micro-hubs
Ackva, Charlotte; Ulmer, Marlin Wolf - 2022
An increasing number of local shops offer local same-day delivery to compete with the online giants. However, the distribution of parcels from individual shops to customers reduces the rare consolidation opportunities in the last mile even further. Thus, shops start collaborating on urban...
