@misc{12788, abstract = {{The product environmental footprint (PEF) is one of two life cycle assessment methods from the European Commission. With their published recommendation on environmental footprint methods, the European Commission provides a framework to assess the PEF for every product in a company. Since there is a high probability that the PEF will be mandatory for companies shortly, it is crucial that this recommendation guides companies and mainly technical employees through all phases of the PEF and enables them to execute a PEF study correctly. Therefore, this paper aims to analyze the process of calculating a PEF for a product critically. A PEF study is conducted on a smart luminaire with the software program OpenLCA. The use case concludes that many aspects of the PEF still need to be clarified. Especially the calculation methods behind every impact category need to be more transparent. Further, a comparison of the use case with a provided tutorial from OpenLCA is made. The comparison shows that no information is available on how to model the end-of-life and the use stages, which are mandatory in a PEF study. (c) 2023 The Authors.

While assistance in a single task via a single interaction modality has been explored previously, crossdevice interaction could improve the quality of assistance, especially given the concurrent and distributed nature of work in CPPSs. In this paper, we present the theoretical foundations and implementation of MiWSICx (Middleware for Work Support in Industrial Contexts), a middleware that showcases how multiple interactive computing devices such as tablets, smartphones, augmented/virtual reality glasses, and wearables could be combined to provide crossdevice industrial assistance. Based on activity theory, MiWSICx models human work as activities combining multiple users, artifacts, and cyber-physical objects. MiWSICx is developed using the actor model for deployment on a variety of hardware alongside a CPPS to provide multiuser, crossdevice, multiactivity assistance.}}, author = {{Dhiman, Hitesh and Röcker, Carsten}}, issn = {{2288-4300 }}, journal = {{Journal of Computational Design and Engineering}}, keywords = {{human–technology interaction, human–computer interaction, crossdevice interaction, cyber-physical systems, assistance, smart factory, middleware, actor model, information system design, industry 4.0}}, number = {{1}}, pages = {{428--451}}, publisher = {{Oxford University Press}}, title = {{{Middleware for providing activity-driven assistance in cyber-physical production systems}}}, doi = {{10.1093/jcde/qwaa088}}, volume = {{8}}, year = {{2021}}, } @inproceedings{4857, abstract = {{Increasing heterogeneity of industrial network systems is a fact and the chances that in the future one communication standard will be able to fulfill the requirements of all possible applications are utopian.

Additionally, due to the increasing amount of network services and traffic, the management of available network resources and the possibility of delivering certain levels of communication quality of service, especially across different network solutions becomes a big challenge. Therefore, in this paper a Controller of Controllers (CoC) concept for management of heterogeneous industrial networks is proposed. The concept is designed to support still widely spread legacy fieldbus systems, different Ethernet-based industrial solutions, and potentially upcoming network technologies. The goal is achieved by leveraging state-of-the-art architectural concepts such as software-defined networks, which allows for integration of abstract models in network management.

Their modular character is resulting from the constantly increasing complexity of such installations, which makes their supervision for securing reliable operation a difficult task: the data of hundreds (if not thousands) of signal sources must be acquired, communicated, and evaluated for system diagnosis. In this contribution we summarize the challenges arising in such applications and show that distributed sensor and information fusion for modular self-diagnosis tackles these challenges. Here, we propose an innovative distributed architecture encompassing intelligent sensor nodes, self-configuring real-time communication networks, and a suitable sensor and information fusion system for condition monitoring. New challenges arise in the context of distributed information fusion systems, which are identified and to which an outlook on future solutions is provided. A number of these solutions have already been discovered, implemented, and are evaluated in the context of a demonstrator, which resembles a real-world printing application.}}, author = {{Mönks, Uwe and Trsek, Henning and Dürkop, Lars and Geneiß, Volker and Lohweg, Volker}}, issn = {{0957-4158}}, journal = {{Mechatronics}}, keywords = {{Cyber-physical systems, Information fusion, Fusion system design, Intelligent sensors, Self-configuration, Intelligent networking}}, number = {{34}}, pages = {{63--71}}, publisher = {{Elsevier}}, title = {{{Towards distributed intelligent sensor and information fusion}}}, doi = {{10.1016/j.mechatronics.2015.05.005}}, year = {{2015}}, } @inproceedings{2167, abstract = {{Cyber-Physical Production Systems (CPPSs) are in the focus of research, industry and politics: By applying new IT and new computer science solutions, production systems will become more adaptable, more resource ef- ficient and more user friendly.
