This study develops a reproducible analytical framework to compare the time?cost efficiency of low-altitude unmanned aerial vehicle (UAV) delivery and ground delivery under identical operational conditions in South Korea, limited to daytime operations between 06:00 and 22:00 and distances of less than 5 km. Based on a supply chain performance perspective, this study proposes a quantitative model that integrates last-mile operational mechanisms into a Time?Cost Efficiency Index (CEI). The model incorporates labor and energy costs and is applied to three distances of 1.5 km, 3.0 km, and 4.5 km under conservative, neutral, and optimistic scenarios. Using a baseline scenario of 3.0 km and λ = 0.5, this study conducts a ±10% one-at-a-time sensitivity analysis, focusing on aerial route linearization and ground detour factors. The results show that, at 3.0 km, UAV delivery reduces unit service costs by approximately 47% compared to ground delivery, with estimated costs of KRW 602 and KRW 1,152, respectively. The CEI increases with distance under the neutral and optimistic scenarios, suggesting that UAV delivery becomes more efficient within the short-distance range. Fuel price fluctuations have the greatest impact on ground delivery costs, whereas routing and geometric factors most strongly affect CEI. These findings indicate that UAV delivery is not universally superior, but becomes advantageous when reduced ground detours, stable operating conditions, and appropriate short-distance route structures are combined. This study provides a transparent framework for evaluating last-mile delivery efficiency and practical implications for route design, drone deployment, fuel cost management, and low-altitude logistics planning.
