@inbook{12740, abstract = {{The high-tech architecture of the 1970s–1990s is typically characterized by the use and exhibition of advanced technologies. In terms of appearance, these buildings often have innovative façades, supporting structures accentuated in color, and expressively displayed technology systems. Unfortunately, however, the rapid obsolescence of technology has often led to the complete replacement of the very systems that defined the architectural form. In 2023, an international conference at ETH Zurich in collaboration with Bauhaus-Universität Weimar explored the question of how best to deal with the structural legacy of technologically innovative architecture. This book summarizes the results and provides an overview of the current state of research.

Improper or lack of maintenance may result in excessive component wear, production quality deterioration, or even longer downtime. However, today's production facilities strive to devote the least amount of necessary maintenance time in order to maximize production time. Therefore, new solutions for deliberate and efficient maintenance are needed. The solution proposed in this paper benefits from the newest trends and innovations in industry, namely the Asset Administration Shell (AAS) which is part of the Industrie 4.0 (I4.0) concept. The AAS shall contain the maintenance submodel which shall be used for supporting humans during the maintenance process. The submodel provides a standardized description of required tools and parts as well as step-by-step instructions which also include safety concerns and multimedia files, such as pictures and videos. In this way, maintenance can be carried out more reliably, resulting in reduced downtime. In addition, feedback from the maintenance process shall be stored in the submodel and fed through an I4.0-compliant network to other processes from different phases of the life cycle in order to improve them.}}, author = {{Lang, Dorota and Grunau, Sergej and Wisniewski, Lukasz and Jasperneite, Jürgen}}, booktitle = {{17th International Conference on Industrial Informatics (IEEE-INDIN 2019)}}, isbn = {{978-1-7281-2928-0 }}, issn = {{1935-4576}}, keywords = {{maintenance, Asset Administration Shell}}, location = {{Helsinki-Espoo, Finland}}, pages = {{768--773}}, publisher = {{IEEE}}, title = {{{Utilization of the Asset Administration Shell to Support Humans During the Maintenance Process}}}, doi = {{10.1109/indin41052.2019.8972236}}, year = {{2019}}, } @inproceedings{4327, abstract = {{In ever changing world, the industrial systems become more and more complex.

Additionally, these sticky notes are enriched with position information. The central element of this approach is an ontology-based context-aware framework, which aggregates and processes data from different sources. As a result, a tablet PC application was implemented, which allows displaying maintenance information as well as live plant process data in the form of augmented reality. More than 100 of those sticky notes can be placed using this system, whereas each note requires a file size of 12 to 16 kilo bytes. After placing a sticky note, the system recognizes it even if the camera's position is not exactly the same as during the placing process.}}, author = {{Flatt, Holger and Koch, Nils and Guenter, Andrei and Röcker, Carsten and Jasperneite, Jürgen}}, booktitle = {{ 2015 IEEE 20th Conference on Emerging Technologies & Factory Automation (ETFA)}}, keywords = {{Maintenance engineering, Augmented reality, Context, Context modelin, Production facilities, Cameras}}, location = {{Luxembourg, Luxembourg}}, publisher = {{IEEE}}, title = {{{A Context-Aware Assistance System for Maintenance Applications in Smart Factories based on Augmented Reality and Indoor Localization}}}, doi = {{10.1109/ETFA.2015.7301586}}, year = {{2015}}, }
