Designing Statewide Drone Delivery Networks in Rural Contexts: A Multiobjective Approach
Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.Last‐mile parcel delivery remains a major challenge in rural areas where unpaved roads, long travel distances, and sparse demand limit the efficiency of truck‐based logistics. This study evaluates the use of cargo drones as a replacement for trucks, focusing on the design of a statewide delivery network supported by multimodal hubs.
