Optimizing Last-Mile Logistics with AI-Powered Truck-Drone Collaboration
This study addresses the "last-mile” delivery challenge in rural logistics by proposing a collaborative route optimization plan for a single truck carrying multiple drones. A mathematical model was established with the objective function of minimizing total delivery cost, which includes the fixed usage costs, delivery costs for both the truck and drones, and the waiting costs for the drones. The Grey Wolf Optimizer (GWO) demonstrated superior performance in cost reduction, mainly by effectively optimizing UAV delivery tasks and routes.
Executive Impact: Transforming Rural Delivery
This research not only validates the effectiveness of the truck-drone collaborative delivery model and the GWO algorithm but also offers valuable practical guidance for configuring the parameters of such systems in real-world applications. Overall, the method proposed in this paper can improve the organization mode of rural last-mile delivery and provide a reference for the implementation of the truck-drone collaborative model in practical scenarios.

Problem Formulation: Truck-Drone Collaborative Delivery
This section details the collaborative problem of truck-drone delivery in rural areas, aiming to minimize total delivery cost. It considers factors like fixed usage costs, delivery costs for both trucks and drones, and drone waiting times. The mathematical model ensures that each customer is visited only once, UAVs operate within endurance and load capacity, and are launched/retrieved by trucks at customer nodes.

Sensitivity Analysis: Key Operational Parameters
This section explores the impact of key operational parameters, such as drone speed and endurance, on the overall delivery cost. It reveals that the relationship between these parameters and total cost is not linear, highlighting the existence of optimal economic ranges for system configuration.
Drone Speed Impact: The analysis showed that a drone speed of 45 km/h yielded the lowest total cost (582.69 yuan) compared to 35 km/h (865.32 yuan) and 55 km/h (2107.87 yuan), demonstrating the importance of optimal speed for efficiency.
Drone Endurance Impact: The optimal economic drone endurance was identified at 1 hour, leading to the minimum total cost of 582.69 yuan. Endurance below this (e.g., 0.5 hours resulting in 2893.04 yuan) significantly increases cost, while exceeding it (e.g., 2.2 hours resulting in 1585.66 yuan) also leads to rising costs due to increased route and waiting expenses. This highlights a critical balance for drone battery life.
Case Study: Real-world Application in Rural Village M
The model was tested using 22 customer points in Rural Village M, showing the GWO algorithm's ability to optimize truck-drone collaborative routes. The truck handled main-line transportation and 11 customer nodes, while four drones managed discrete, distant last-mile deliveries to the remaining 11 nodes. This division of labor significantly reduced total logistics delivery time and cost, demonstrating the practical efficacy of the approach for scattered rural customer points.
