Abstract
This study investigates multi-UAV cooperative operations under urban drone logistics service processes. It clarifies the end-to-end workflow, including order generation, loading and takeoff preparation, en-route delivery, service completion, and return for recharging or battery swapping. Key constraints are extracted and integrated into a unified task assignment and scheduling model, including task time windows, vertiport service capacity and operational sequencing, as well as UAV range and energy limitations, with the objective of minimizing total completion time and overall delay. A solution method combining Earliest Due Date (EDD) ordering and heuristic assignment is developed. Simulation experiments compare strategies with and without process constraints, validating the feasibility and effectiveness of the proposed model and method in terms of makespan, on-time rate, and UAV utilization.
