  • Title: A framework of identifying relevant dimensions in assessing a digitalization model for companies operating in the fashion industry
  • Author(s): Emil Constantin Loghin, Ion Verzea, Adrian Vilcu, Bogdan Rusu and Carmen Tita from “Gheorghe Asachi” Technical University of Iași, Faculty of Industrial Design and Business Management, Romania

  • Abstract: The purpose of this paper is to identify relevant aspects regarding the digital transformation process of companies in the fashion industry production market, how the process is perceived by the managers of these companies, and the existence of a digitalization strategy. As a tool for qualitative research, a semi-structured interview was used to collect opinions on the digitalization process of companies in the fashion industry from experts with experience in digital transformation, based on the evolution of their own companies (…).

  • Title: Addressing the challenge of process stability control in wire DED-LB/M process
  • Author(s): Panagiotis Stavropoulos, Georgios Pastras, Konstantinos Tzimanis and Nikolas Bourlesas from the Laboratory for Manufacturing Systems and Automation, Department of Mechanical Engineering and Aeronautics, University of Patras

  • Abstract: The wire DED-LB/M AM process is fast, cost-effective and it creates high-quality, dense parts. However, its industrial adoption is limited since process stability needs complex monitoring devices and tools. This work proposes a twofold strategy to resolve this issue; A fast-running, physics-based simulation tool calculates the temperature field during the building of single walls, while, an affordable vision-based monitoring system captures the melt pool dimensions that are correlated (…).

  • Title: Process window development of DED-LB/M process with coaxial wire for stainless steel AISI 316L
  • Author(s): Panagiotis Stavropoulos, Harry Bikas, Konstantinos Tzimanis and
    Nikos Porevopoulos from Laboratory for Manufacturing Systems and Automation, Department of Mechanical Engineering and Aeronautics,
    University of Patras; Adriano Nicola Pilagatti, Eleonora Atzeni, Luca Iuliano and Alessandro Salmi from the Department of Management and Production Engineering, Politecnico di Torino.

  • Abstract: This work is focused on the development of a process window for
    the laser-based directed energy deposition additive manufacturing (AM)
    process with coaxial wire as feedstock (DED-LB/M) as well as on the
    investigation of the significance of process parameters on the bead
    dimensions (…).

  • Title: Simulation Power vs. Immersive Capabilities: Enhanced Understanding and Interaction with Digital Twin of a Mechatronic System
  • Author(s): Constantin-Catalin Dosoftei from the Department of Automatic Control and Applied Informatics, “Gheorghe Asachi” Technical University of Iasi

  • Abstract: Automation Studio, a specialised simulation software, offers virtual commissioning capabilities and robust tools for modelling the behaviour and performance of a pneumatic robot controlled by a PLC. Conversely, Unity is a versatile platform primarily used for creating high-quality 3D games and interactive simulations, providing immersive experiences with DTs through mixed-reality environments. This paper provides a study that compares and  (…).

  • Title: A digital twin framework for prediction, monitoring, and diagnosis in copper tube extrusion
  • Author(s): Kyriakos Sabatakakis, Panagiotis Stavropoulos, Apostolos Kaimenopoulos, Dimitrios Karatasios

  • Abstract: The strict quality requirements, the increased production rates, variability, and volume constitute challenges in the quality of extruded profiles. State-of-practice methods cannot track down or mitigate all the product features and defects, thus increasing scrap generation and reducing production flexibility. Nevertheless, State-of-the-art approaches are few and dedicated to the product rather than the actual process with the last being researched in terms of process modeling. This study assesses the adoption level of I4.0 technologies in extrusion applications and it applies well-established practices across manufacturing to outline a Digital Twin framework for Prediction, Monitoring, and Diagnosis in the case of copper tube extrusion.

  • Title: Achieving resilience through reconfigurability: The role of digitisation for improved strategy and decision-making for EU manufacturing industries
  • Author(s): Emmanouil Bakopoulos, Tjerk Timan and Kosmas Alexopoulos

  • Abstract: The term resilience has regained traction in EU policy since the Covid-19 crisis and the invasion of Ukraine, ending a period of relative stability. Whereas the term Resilience connects to multiple disciplines and sometimes is referred to as ‘black swan’ events, when looking at the EU policy context, we can see that it relates mainly to national (member-state) and EU-level economic abilities to responds to global shocks. In the EU strategic agenda the chosen response to a multitude of recent crises is to intensify (twin) transitions (…).
