Optimization of Truck-Drone Distribution Paths: A Review

Abstract

The rapid development of unmanned aerial vehicle (UAV) technology has led to a notable increase in the use of cargo drones across various civil logistics sectors. Small rotor UAVs are particularly advantageous for last-mile logistics distribution due to their flexibility in takeoff and landing and their cost-efficiency. Nonetheless, their limited load capacity and range hinder their ability to perform long-distance deliveries and transport heavier cargo. This limitation has prompted the evolution of truck-drone distribution systems, where trucks function as mobile warehouses and charging stations for UAVs, thereby significantly extending their operational range. This paper provides a review of the relevant literature on optimizing distribution routes for truck-mounted UAVs, summarizing current research progress and discussing potential future research directions in this area.
