Public and private actors in cities have embarked on a race to achieve net-zero carbon emissions. However, parcel delivery in urban areas is booming, especially due to e-commerce. This context necessitates the study of sustainable transportation use. Among the various city-center parcel delivery modes, delivery by river is largely understudied. This study proposes a cost calculation model for delivery by inland waterways. This model considers fixed and variable costs for pre-carriage, transshipment, and last-mile delivery using a two-echelon last-mile delivery network framework. The model is tested using a real-life French case study and worldwide academic investigation. The results show that load optimization is key for profitability and that the most important costs are personnel and investment costs.

城市中的公共和私人参与者已经开始了实现净零碳排放的竞赛。然而，城市地区的包裹递送正在蓬勃发展，尤其是由于电子商务。在这种背景下，有必要研究可持续交通利用。在各种市中心包裹递送方式中，河道递送的研究还很不够。本研究提出了内陆水道运输的成本计算模型。该模型使用两级最后一英里交付网络框架考虑预运输、转运和最后一英里交付的固定和可变成本。该模型通过现实生活中的法国案例研究和全球学术调查进行了测试。结果表明，负载优化是盈利的关键，最重要的成本是人员和投资成本。
