62. A Sustainable Approach to Urban Last-Mile Logistics: Modeling and Analysis of a Green Two-Echelon Location-Routing Problem with Eco-Conscious Customer Behavior

Valentina Bonomi (tecnico.ulisboa.pt)

Apresentação regular

The rapid expansion of e-commerce has placed unprecedented pressure on urban logistics: Last-Mile Delivery (LMD) now poses a significant environmental impact contributing to over 30% of total CO2 emissions in the delivery sector and worsening congestion. We propose a Green Two-Echelon Location-Routing Problem (G2E-LRP), explicitly integrating (i) a heterogeneous fleet with both conventional...

28. Collaborative Strategies for Efficient Environmental Cost Distribution in Sustainable Supply Chains

Maria da Graça de Sousa Martinho Raposo (tecnico.ulisboa.pt)

Apresentação regular

Growing environmental concerns and increasingly stringent regulations have compelled supply chains (SC) to rethink how they distribute the costs of environmental impacts. However, this is a complex challenge, especially when trying to balance sustainability with financial performance and fair cost-sharing among stakeholders. This paper addresses this challenge by developing a decision support...

104. Design and planning of sustainable supply chains regulated by government incentives

Marcelo Pinto (Departamento de Engenharia Mecânica, CEMMPRE, ARISE, Universidade de Coimbra, Coimbra, Portugal)

Apresentação regular

The design of modern supply chains should account for stimulating economic growth by establishing efficient material and information flows. Yet, the same economic growth trend that fuels supply chains is also contributing to the unsustainable use of resources. This challenge provides the conceptual leverage for this work: to model the government’s role as a central agent in the transition...

88. Optimising Insect-Production Facility Location: A Bi-objective Cost–Sustainability Model

RUBEN PEREIRA (ipp.pt)

Apresentação regular

The insect-production industry has been growing rapidly, creating a demand for new decision-support tools. Locating insect-production facilities, however, is difficult because site choice directly affects the cost savings and sustainability benefits that can be achieved. A poor location can undermine a project: if a plant is not close to sources of insect feed, transporting the necessary...
