Development of a Learning Factory for Industry 5.0 Based on Open Design

Authors

Publication
Procedia Computer Science

Abstract
This project focuses on the development and implementation of a Mini Learning Factory (Mini LF) 5.0, aligned with the principles of Industry 5.0, Cyber-Physical Systems (CPS), and Open Design. Industry 5.0 emphasizes human-centric innovation, fostering collaboration between humans and machines while promoting sustainability. CPS facilitates the integration of the physical and digital realms, enabling more agile and flexible production processes. Open Design plays a pivotal role by encouraging collaborative participation, transparency, and the democratization of knowledge, which leads to more personalized and sustainable solutions in product and service design. The research adopts the Design Science Research (DSR) methodology, involving problem identification, artifact development, evaluation, and iterative improvement. The goal is to create a replicable, low-cost training environment that equips students with practical skills in line with Industry 5.0's requirements. The Mini LF 5.0 also aims to explore new methods for human-machine interaction, collaborative communication, and sustainable production, while ensuring the technical and financial viability of the project for wider adoption. © 2025 The Authors.

Mobile-Depots and Cargo Bikes Towards a Sustainable Last-Mile Future

TRANSPORT TRANSITIONS: ADVANCING SUSTAINABLE AND INCLUSIVE MOBILITY, TRA CONFERENCE, 2024, VOL 4

Abstract
E-commerce growth is driving the need for novel, more sustainable last-mile delivery strategies. One potential strategy is based on setting up a mobile-depot from where last-mile deliveries are conducted using cargo bikes. This research explores the impacts of this strategy through a microscopic traffic simulation based on a medium-sized European city. The strategy was evaluated at three levels: operational (route length and duration), energy consumption, and emissions. The results showed that adopting a last-mile delivery strategy based on a mobiledepot and cargo bikes leads to significant benefits in terms of energy consumption and emission, which decrease by more than 80 %, but imply lengthier (+49 %) and more time-consuming (+14 %) routes compared to a traditional parcel delivery strategy.

HUMAN-CENTRED TECHNOLOGY MANAGEMENT FOR A SUSTAINABLE FUTURE, VOL 2, IAMOT

Abstract
E-commerce popularity has increased the challenges of parcel deliveries, highlighting the urgency in addressing the sustainability of the last-mile, which is considered the most ineffective part of the supply chain and a source of environmental and social issues. Although different alternative last-mile technologies have already been proposed, they all imply complex trade-offs. This study explores how synergies between delivery technologies could improve last-mile logistics. It evaluates the trade-offs between electric vans, cargo bikes, and parcel lockers, and takes into account factors such as package size, consumer requirement, and urban context. The adoption of a combined delivery strategy suggests environmental and social benefits like the mitigation of congestion and emissions while ensuring advantages for companies due to streamlined operations and offering consumers a broader range of choices.

Abstract
Technological evolution is very present in today’s world. The Internet of Everything (IoE) is one of the next steps in this evolution. WordPress is a website-building tool that is used today to its minimum capability. The main problem is how to make WordPress customizable and reliable to support device networking and communication. This can be done by implementing a new architecture that supports WordPress as a powerful tool, allowing for scalability and maintenance. The adoption of a recent trend known as DevOps is an important step in creating and developing a strong website and ensuring its integration with multiple devices. It emphasizes continuous testing, delivery, and integration. This article is based on a literature review to justify using micro-services architecture and the DevOps approach to build a reliable and robust working tool in WordPress that can be part of the IoE. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2025.

Lecture Notes in Intelligent Transportation and Infrastructure

Abstract
The current era where living demands an accelerated digital transition mainly focused on encouraging a smarter, healthier, and more sustainable mobility, in all its dimensions – a must concern for the young generations. The convergence through several digital services and APP can be an attitudes and perception changer within the group of academic mobility users’, promoting a more sustainable and better mobility choices that impact on the academic user’s mobility routines. Thus, encouraging a global shift to shared and active mobility services and systems bringing significant contributions to environmental sustainability and, also, to users’ health. The Academic Mobility as a Service (AMaaS) provide a digital service with mobility alternatives to support the academic population geographically located in different faculty campuses and Higher Education Institutions (HEI). The AMaaS applied to a restrict group is helpful to test innovative transport solutions and its high cybersecurity vulnerabilities. Despite the shortage of AMaaS case studies and the lack of security reference, it is imperative that a cybersecurity by design is planned and included in AMaaS design. In this paper AMaaS critical cybersecurity challenges, and potential risks are discussed and AMaaS Security by Design framework is described. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
