Abstract
The rapid rise of e-commerce has amplified the need for logistics operators to offer fast, reliable, and eco-friendly last-mile delivery (LMD) services. Today, LMD activities account for more than 30% of total CO₂ emissions in the logistics sector, contributing to increased urban congestion, noise pollution, and energy consumption. To confront these challenges, we propose a novel, sustainability-oriented LMD model that incorporates both operational and tactical decision-making to minimize emissions from both client and company sources. Specifically, we optimize a two-echelon system by adopting multiple transportations modes.
A distinguishing feature of this approach is the explicit inclusion of diverse customer behaviors, accounting for varying levels of environmental awareness. We develop a MILP model whose objective function targets overall emissions as well as the cost of integrating satellites. Validated on realistic datasets covering both densely populated urban zones and sparsely inhabited areas, our method sheds light on the trade-offs between cost, service quality, and environmental impact. These insights offer clear, actionable guidelines for logistics providers aiming to implement more sustainable and efficient LMD practices, accounting for emissions from both company operations and client choices.
