Interactive digitally supported design of human-centric workplaces in learning factories
Full text linkIndustrial workplaces must adapt to the worker to guarantee the sustainability proposed by the concept of Industry 5.0. This research aims at contributing to the human-centered development of processes based on an integrated framework supported by three pillars: design, assessment and modelling. Through the combination of manufacturing tools such as an ergonomically adapted value stream map, Digital Human Model simulation using ema Work Designer (emaWD), and collaborative design with Nvidia Omniverse, a case study was applied at the learning factory of the University of Twente. The employment of the framework allowed a systematic analysis of the process and gathered insights for triggering improvement cycles to balance the system’s performance and worker’s well-being.</p
Circular Manufacturing Systems in Learning Factories
Full text linkCircular Manufacturing Systems (CMS) have emerged as a paradigm for integrating disassembly and potential remanufacturing processes into factories. This is also a relevant topic for learning factories whereas studies indicate that limited concepts are available nowadays. Given that, the paper explores the integration of CMS principles as well as specific processes and system setups into learning factories. A methodological approach is introduced to facilitate the systematic development of CMS approaches for learning factories. The proposed approach is exemplarily applied in the Learning Factory of the University of Twente to test functionality and feasibility.</p
Cyber Physical System for Reconfigurable Learning Factories:Combining 3D Simulations, Reconfigurable Layouts and Real-Time Locating Systems
Full text linkLearning Factories are educational environments that replicate manufacturing environment operations, providing next-generation engineers with hands-on learning opportunities. University-based Learning Factories may encounter barriers in supporting a wide range of learning courses with different intended learning objectives and outcomes that impede their successful implementation and can prevent valuable learning experiences. Overcoming these barriers requires dedicated efforts to enhance the infrastructural capabilities of the Learning Factory to become multi-use, invoking better flexibility and reconfigurability of the layout besides utilization of value-enhancing technologies. For this purpose, this work investigates the learning opportunities to enable data-driven layout reconfigurations by fusing 3D simulations with Real Time Locating Systems (RTLS). The seamless integration of these digital solutions provides accurate tracking and modeling of whichever manufacturing entity. Mirroring physical systems configurations into digital environments triggers learners to better analyze process functioning and performances. This digital solution is even more effective into modern mass-customized markets, where batch-centered production processes require easy-to-deploy and iterative layout optimizations. The findings of this empirical study support the transformative potential of achieving reconfigurable layouts alongside RTLS and 3D simulation technologies within a Learning Factory. This integrated approach is not limited to enhancing capabilities and operational efficiency but also provides a wider and multi-dimensional array of educational experiences, bridging the gap between academia and an ever-evolving manufacturing landscape.</p
Mixed reality meets circular economy: The case of battery lifecycle management
No full textDespite recent digitalization efforts across European industries, research gaps persist in applying mixed reality (MR) within circular economy (CE) frameworks. Specifically, there is limited exploration of data integration, an unclear value proposition for digital tools, and minimal engagement from business perspectives. Despite growing interest, a structured framework mapping MR applications to CE processes remains underexplored. This paper addresses this gap by mapping MR modules to CE practices across lifecycle phases, illustrating specific use cases in design, manufacturing, use, and end-of-life stages. The paper also exploits MR applications for sustainable battery manufacturing, using real-time data to monitor and guide disassembly and recycling processes. This work contributes to advancing sustainable practices and facilitating the transition to circular business models by demonstrating the role of MR in promoting efficient resource use, disassembly, and recycling within a closed-loop system
Development of an IALF overarching learning module for circular economy
Full text linkThe increasing importance of sustainable business models due to the scarcity of resources and resulting political regulations leads many companies and research institutions towards the concept of Circular Economy. Subsequently, the learning factory community is facing the challenge of expanding existing concepts to include Circular Economy in their learning factories. Therefore, a learning factory- and competency-based module for Circular Economy is developed by eight members of the International Association of Learning Factories to define a common ground. The module covers the basics of Circular Economy in the production environment and make it tangible through concrete use cases. To achieve these goals, extensive research on existing concepts has been conducted by IALF experts to analyze learning objectives and requirements in detail and derive required competencies. Based on that, the learning module is developed
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
