Digital Twin Technology and Architecture

Digital Twin Technology and Architecture

A synthesis of concept and practice
Arka Mukherjee ORCID Icon, Shibaji Chandra ORCID Icon
Digital twins are a key enabling technology of the fourth industrial revolution, integrating physical systems with their digital counterparts to create intelligent, data-driven environments. This conceptual/practice-oriented paper examines how to establish a modern architectural framework for digital twins leverages modern tech-stack like IoT, Data Fabric, AI/ML, seamless integration and enterprise grade security. The paper is grounded in an abundance of literature by leading vendors and analysts in space. It offers a comparative study of different vendors implementing the solution stack in the proposed architecture.

Digital Factory Planning for Startups

Digital Factory Planning for Startups

A simulation-based production structure design
Herwig Winkler ORCID Icon, Tobias Isau
With the increasing complexity of production and logistics systems, traditional factory planning approaches are reaching their limits. In this context, digital factory planning offers a promising solution for enabling well-informed decisions, particularly during the early planning phases. For startups, the optimal planning of a production facility is challenging, as they often operate with limited financial and infrastructural resources. This paper presents a methodological approach to digital factory planning that utilizes VR simulation for the layout planning of a factory hall for a young company in the solar industry. The proposed approach demonstrates how simulations can support the design of flexible production structures, particularly in startup environments.

Developing Virtual Reality in Learning Contexts

Developing Virtual Reality in Learning Contexts

Navigating efficiency, content relevance and scalability
Stella Kanatouri ORCID Icon, Oliver Sosna ORCID Icon, Alexander Kulik, Sina C. Truckenbrodt ORCID Icon, Friederike Klan ORCID Icon, Christian Erfurth ORCID Icon
While virtual reality can facilitate hands-on learning, its development faces barriers, including high costs and time demands and scalability challenges. This article presents two case studies that illustrate strategies for overcoming such barriers when training the next generation of skilled workers in environmental technologies. By examining approaches for streamlining development and increasing content relevance and scalability, we highlight lessons learned for future practice. We conclude by envisioning a future in which educational institutions can flexibly and cost-effectively prototype virtual reality in learning contexts, ensuring alignment with curricular goals and learners’ needs.

Immersive Human Digital Twins for Industry 4.0

Immersive Human Digital Twins for Industry 4.0

Supporting adaptive human-centric production by integrating cognitive and physical states
Tajbeed A. Chowdhury ORCID Icon, Martina Lehser ORCID Icon, Eric Wagner ORCID Icon, Paul Motzki ORCID Icon
The rapid advancement of immersive technologies has created new opportunities to transform human-machine collaboration in industry. This paper presents an immersive platform with a digital twin that combines both physical and cognitive characteristics of human dynamics. By integrating multimodal sensing, human biomechanics, and cognitive state into digital twin technology, the proposed system enhances operational safety and ensures better ergonomics. The main argument is that human digital twins are not only desirable but essential for next-generation industrial systems. We discuss the limitations of existing human modeling approaches, outline the conceptual foundations of human digital twins, and demonstrate their industrial relevance across safety, productivity, ergonomics and sustainability.

Comparing Industry 4.0 Maturity Models

Comparing Industry 4.0 Maturity Models

Jochen Schumacher, Norbert Gronau ORCID Icon
In recent years, numerous maturity models have been developed with the aim of providing a clear indication of the progress each company has made in terms of Industry 4.0 development. However, not all models include all aspects of Industry 4.0. The models are also not equally practical. This article offers an in-depth comparison and assessment of the comprehensiveness of the ten most important Industry 4.0 maturity models.

Ecological Benefits of Industry 4.0

Ecological Benefits of Industry 4.0

A Qualitative-Empirical and Literature-Based Study
Kai-Ingo Voigt, Marc Rücker, Johannes W. Veile
Industry 4.0 describes the digitization and interconnection of industrial value creation. So far, economic and technological potentials have been considered in particular, while ecological opportunities through industry 4.0 receive less attention. This article examines the ecological potentials of Industry 4.0 in terms of resources, energy consumption, logistics and transport, waste and emissions, from which propositions are derived. The study attempts to better understand of the ecological potentials of Industry 4.0 in order to contribute to more sustainable industrial value creation.
