Life Cycle Engineering (LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic information and improvement potentials regarding eco-efficient products. Key factors influencing LCAs of automotive components, such as material production, will change in the future. First approaches for integrating future scenarios for these key factors into LCE already exist, but they only consider a limited number of parameters and scenarios. This work aims to develop a method that can be practically applied in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive components, considering relevant parameters and consistent scenarios. Therefore, pLCA methods are further developed to investigate the influence of future scenarios on the GHG emissions of automotive components. The practical application is demonstrated for a vehicle component with different design options. This paper shows that different development paths of the foreground and background system can shift the ecological optimum of design alternatives. Therefore, future pathways of relevant parameters must be considered comprehensively to reduce GHG emissions of future vehicles. This work contributes to the methodological and practical integration of pLCA into automotive development processes and provides quantitative results.</jats:p>","lang":"eng"}],"related_material":{"link":[{"relation":"supplementary_material","url":" https://www.mdpi.com/article/10.3390/su151310041/s1"}]},"publication":"Sustainability","issue":"13","keyword":["prospective LCA","life cycle engineering (LCE)","lightweight design","automotive components","body parts","circular economy","steel","aluminum","hybrid materials","fiber metal laminates"],"type":"journal_article","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"date_created":"2023-06-27T06:35:20Z"},{"language":[{"iso":"eng"}],"_id":"45793","user_id":"66731","status":"public","title":"Data-Driven Product Management: A Practitioner-Driven Research Agenda","year":"2023","conference":{"location":"Sydney","name":"33rd CIRP Design Conference"},"author":[{"full_name":"Grigoryan, Khoren","last_name":"Grigoryan","first_name":"Khoren"},{"id":"66731","full_name":"Fichtler, Timm","first_name":"Timm","orcid":"https://orcid.org/0000-0001-6034-4399","last_name":"Fichtler"},{"full_name":"Schreiner, Nick","last_name":"Schreiner","first_name":"Nick"},{"full_name":"Rabe, Martin","first_name":"Martin","last_name":"Rabe"},{"id":"72658","full_name":"Panzner, Melina","last_name":"Panzner","first_name":"Melina"},{"last_name":"Kühn","first_name":"Arno","full_name":"Kühn, Arno"},{"first_name":"Roman","last_name":"Dumitrescu","full_name":"Dumitrescu, Roman","id":"16190"},{"id":"43136","first_name":"Christian","last_name":"Koldewey","orcid":"https://orcid.org/0000-0001-7992-6399","full_name":"Koldewey, Christian"}],"date_updated":"2023-06-27T13:57:42Z","date_created":"2023-06-27T13:46:45Z","type":"conference","keyword":["Product Management","Data Analytics","Data-Driven Design","Product-related data","Lifecycle Data","Tool-support"],"department":[{"_id":"563"},{"_id":"241"}],"publication":"Procedia CIRP 33","citation":{"bibtex":"@inproceedings{Grigoryan_Fichtler_Schreiner_Rabe_Panzner_Kühn_Dumitrescu_Koldewey_2023, title={Data-Driven Product Management: A Practitioner-Driven Research Agenda}, booktitle={Procedia CIRP 33}, author={Grigoryan, Khoren and Fichtler, Timm and Schreiner, Nick and Rabe, Martin and Panzner, Melina and Kühn, Arno and Dumitrescu, Roman and Koldewey, Christian}, year={2023} }","chicago":"Grigoryan, Khoren, Timm Fichtler, Nick Schreiner, Martin Rabe, Melina Panzner, Arno Kühn, Roman Dumitrescu, and Christian Koldewey. “Data-Driven Product Management: A Practitioner-Driven Research Agenda.” In <i>Procedia CIRP 33</i>, 2023.","ama":"Grigoryan K, Fichtler T, Schreiner N, et al.

Product management - as the bridge between market and company - has the task to absorb and combine the manifold requirements and make the right product-related decisions. In the process, product management is confronted with heterogeneous information, rapidly changing portfolio components, as well as increasing product, and organizational complexity. Combining and utilizing data from different sources, e.g., product usage data and social media data leads to promising potentials to improve the quality of product-related decisions. In this paper, we reinforce the need for data-driven product management as an interdisciplinary field of action. The state of data-driven product management in practice was analyzed by conducting workshops with six manufacturing companies and hosting a focus group meeting with experts from different industries. We investigate the expectations and derive requirements leading us to open research questions, a vision for data-driven product management, and a research agenda to shape future research efforts."}]},{"date_updated":"2025-07-16T11:06:47Z","publication_status":"published","year":"2023","title":"Re-Envisioning Industrial Control Systems Security by Considering Human Factors as a Core Element of Defense-in-Depth","author":[{"id":"405","first_name":"Jens","last_name":"Pottebaum","orcid":"http://orcid.org/0000-0001-8778-2989","full_name":"Pottebaum, Jens"},{"first_name":"Jost","last_name":"Rossel","orcid":"0000-0002-3182-4059","full_name":"Rossel, Jost","id":"58331"},{"id":"83504","full_name":"Somorovsky, Juraj","first_name":"Juraj","orcid":"0000-0002-3593-7720","last_name":"Somorovsky"},{"id":"94636","full_name":"Acar, Yasemin","first_name":"Yasemin","last_name":"Acar"},{"id":"111","first_name":"René","last_name":"Fahr","full_name":"Fahr, René"},{"full_name":"Arias Cabarcos, Patricia","first_name":"Patricia","last_name":"Arias Cabarcos","id":"92804"},{"id":"59256","full_name":"Bodden, Eric","last_name":"Bodden","first_name":"Eric","orcid":"0000-0003-3470-3647"},{"id":"47565","full_name":"Gräßler, Iris","orcid":"0000-0001-5765-971X","last_name":"Gräßler","first_name":"Iris"}],"doi":"10.1109/eurospw59978.2023.00048","main_file_link":[{"url":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10190647"}],"language":[{"iso":"eng"}],"abstract":[{"text":"The security of Industrial Control Systems is relevant both for reliable production system operations and for high-quality throughput in terms of manufactured products.

Dieses Verfahren kann jedoch nur dann mit optimaler Geschwindigkeit\r\ngenutzt werden, wenn Engpässe wirksam vermieden werden können. Einer dieser\r\nEngpässe ist der Konstruktionsprozess. Gerade im Bereich der additiven Fertigung\r\nsind in letzter Zeit immer leistungsfähigere Softwarelösungen erschienen, die das\r\nDesign für die additive Fertigung, einschließlich der meisten Computer-Aided-Design\r\n(CAD)-Aufgaben, beschleunigen. In vielen Bereichen wird daher bereits versucht, so\r\nviele Schritte wie möglich zu automatisieren, nicht selten unter Verwendung\r\nneuronaler Netze und künstlicher Intelligenz. Dieser Beitrag zeigt am Beispiel einer\r\nautomatisierten Strukturoptimierung eines Stuhls, warum das Nutzen neuronaler\r\nNetze im Konstruktionsprozess sinnvoll ist, um die Bereiche der konventionellen\r\nTopologieoptimierung und des Generative Design weiter zu verknüpfen und somit die\r\nProduktentwicklungszeit zu reduzieren.","lang":"ger"}]},{"abstract":[{"lang":"eng","text":"Due to the increasing influences of a VUCA world, design thinking workshops have been established as a standard technique to build solutions according to uncertain customer needs. Concerning the ongoing pandemic and rising development of solutions across organizations, more and more workshops were conducted online with software support. However, existing software tools insufficiently address the different workshop situations in terms of the process (i.e., fixed tasks to conduct), the place (e.g., static online whiteboards), and people (i.e., synchronous working of all stakeholders).\r\nTherefore, we propose a design science study to develop a situation-specific software support that can be configured with flexible development processes, different places, and task-related people. Based on practical experience in existing research projects, we derive the initial design requirements and map them to a set of design principles. Out of that, we design a concept with its implementation as a software tool and point out open challenges.

Automated approximate accelerator synthesis involves a great deal of complexity on the size of design space which exponentially grows with the number of possible approximations. Design space exploration of approximate accelerator synthesis is usually targeted via heuristic-based search methods. The majority of existing frameworks prune a large part of the design space using a greedy-based approach to keep the problem tractable. Therefore, they result in inferior solutions since many potential solutions are neglected in the pruning process without the possibility of backtracking of removed approximate instances. In this paper, we address the aforementioned issue by adopting Monte Carlo Tree Search (MCTS), as an efficient stochastic learning-based search algorithm, in the context of automated synthesis of approximate accelerators. This enables the synthesis frameworks to deeply subsamples the design space of approximate accelerator synthesis toward most promising approximate instances based on the required performance goals, i.e., power consumption, area, or/and delay. We investigated the challenges of providing an efficient open-source framework that benefits analytical and search-based approximation techniques simultaneously to both speed up the synthesis runtime and improve the quality of obtained results. Besides, we studied the utilization of machine learning algorithms to improve the performance of several critical steps, i.e., accelerator quality testing, in the synthesis framework. The proposed framework can help the community to rapidly generate efficient approximate accelerators in a reasonable runtime."}],"date_created":"2021-06-14T14:05:17Z","department":[{"_id":"78"}],"keyword":["Approximate computing","Design space exploration","Accelerator synthesis"],"type":"conference"},{"_id":"21727","publisher":"AIS","language":[{"iso":"eng"}],"user_id":"47208","conference":{"location":"Virtual Conference/Workshop","name":"29th European Conference on Information Systems (ECIS)"},"author":[{"id":"29951","last_name":"Vorbohle","first_name":"Christian","full_name":"Vorbohle, Christian"},{"full_name":"Gottschalk, Sebastian","last_name":"Gottschalk","first_name":"Sebastian","id":"47208"}],"status":"public","title":"Towards Visualizing and Simulating Business Models in Dynamic Platform Ecosystems ","year":"2021","date_updated":"2022-01-06T06:55:12Z","publication_status":"accepted","date_created":"2021-04-23T13:38:54Z","department":[{"_id":"66"},{"_id":"534"},{"_id":"276"}],"keyword":["Platform Ecosystems","Platform Ecosystem Modeling Language","Platform Ecosystem Development Tool","Business Models","Design Science"],"type":"conference","citation":{"ama":"Vorbohle C, Gottschalk S.

Despite the success of prominent examples, such as Uber and Airbnb, creating a profitable platform ecosystem presents a key challenge for many companies across all industries. Although research provides knowledge about platforms’ different value drivers (e.g., network effects), companies that seek to transform their current business model into a platform-based one lack an artifact to reduce knowledge boundaries, collaborate effectively, and cope with the complexities and dynamics of platform ecosystems. We address this challenge by developing two artifacts and combining research from variability modeling, business model dependencies, and system dynamics.

Unternehmen agieren hierbei als Anbieter von Software-Plattformen, auf denen Drittanbieter Softwarelösungen für den Markt anbieten können.  Etablierte Beispiele sind hierbei sogenannte App-Stores, die z.B. von Google oder Apple angeboten werden.\r\n\r\nBeim Aufbau von Software-Ökosystemen müssen vom Plattformanbieter viele architektonische Entwurfsentscheidungen getroffen werden. Bisher gibt es keine Architekturrichtlinien und -werkzeuge, die den Entwurf einer Ökosystemarchitektur unterstützen. Dadurch fehlt hier systematisches, wiederverwendbares Wissen. Plattformanbieter müssen auf ad-hoc Entscheidungen zurückgreifen. Dies kann dann zu Problemen im Betrieb der Software-Plattformen führen, zu erhöhten Ausfallrisiken und Mehrkosten.\r\n\r\nDer Mangel an Architekturwissen manifestiert sich konkret in zwei Gruppen von Herausforderungen: Erstens fehlt eine Wissensbasis zu Architekturalternativen und zweitens fehlt es an methodischem Wissen zu Entwicklung und Betrieb von Software-Ökosystemen. Eine Architekturwissensbasis würde Orientierungshilfen zu den Bestandteilen von Software-Ökosystemen und deren Abhängigkeiten geben, während methodisches Wissen die Erstellung dieser Systeme erleichtern würde.\r\n\r\nIn der Dissertation werden diese Herausforderungen durch die Entwicklung des Frameworks SecoArc für die Modellierung von Software-Ökosystemen angegangen. Der Beitrag der Dissertation ist zweifach: \r\n1.\tDas SecoArc-Framework umfasst eine Architekturwissensbasis, die wiederverwendbare Architekturentwurfsentscheidungen\r\nvon Software-Ökosystemen enthält. Die Wissensbasis wurde entwickelt, indem das Architekturwissen bestehender Ökosysteme sowie aus existierender Fachliteratur ermittelt wurde und in einer Produktlinie für Software-Ökosysteme konsolidiert wurde. Die Produktlinie umfasst architektonische Gemeinsamkeiten und Variabilitäten von Software-Ökosystemen. \r\n2.\tDas SecoArc-Framework liefert methodisches Wissen, um die Ökosystemarchitektur in Modellen zu entwerfen und zu analysieren. Dieses Wissen wurde entwickelt, indem drei Architekturmuster identifiziert wurden. Jedes Muster erfasst unterschiedliche Beziehungen zwischen architektonischen Entwurfsentscheidungen zu den Qualitätsmerkmalen einer Ökosystemgesundheit und der Erreichung von Geschäftszielen. \r\n\r\nDie Architekturmuster und die Produktlinie wurden dazu genutzt, ein Modellierungsframework zu entwickeln und in Form eines Prototypen umzusetzen, welches einen Entwurfsprozess, eine Modellierungssprache und eine Architekturanalysetechnik umfasst. Es erleichtert das Modellieren, Analysieren und Vergleichen von Ökosystemarchitekturen.\r\n\r\nDie Ergebnisse der Dissertation wurden im Rahmen von zwei Studien evaluiert. In der ersten Validierungsstudie wurden das Framework sowie der Prototyp verwendet, um zwei alternative Ökosystemarchitekturen zu entwerfen und zu analysieren. In der zweiten Studie wurde eine Analyse von existierenden Ökosystemen basierend auf den architektonischen Variabilitäten des Frameworks durchgeführt."}],"_id":"28683","ddc":["000"],"user_id":"36399","status":"public","has_accepted_license":"1","file_date_updated":"2022-12-30T22:15:15Z","supervisor":[{"id":"107","last_name":"Engels","first_name":"Gregor","full_name":"Engels, Gregor"}],"citation":{"ama":"Schwichtenberg B. <i>Modeling and Analyzing Software Ecosystems</i>.; 2021. doi:<a href=\"https://doi.org/10.17619/UNIPB/1-1270 \">10.17619/UNIPB/1-1270 </a>","bibtex":"@book{Schwichtenberg_2021, title={Modeling and Analyzing Software Ecosystems}, DOI={<a href=\"https://doi.org/10.17619/UNIPB/1-1270 \">10.17619/UNIPB/1-1270 </a>}, author={Schwichtenberg, Bahar}, year={2021} }","mla":"Schwichtenberg, Bahar. <i>Modeling and Analyzing Software Ecosystems</i>. 2021, doi:<a href=\"https://doi.org/10.17619/UNIPB/1-1270 \">10.17619/UNIPB/1-1270 </a>.","short":"B.

Today, process design, development, and optimization is most likely based on the knowledge of process engineers and is mainly performed by experimental testing. In this contribution, a newly developed simulation tool is presented, to reduce time and costs and efficiently determine optimized process parameter. Based on a co-simulation of MATLAB and ANSYS, the different physical phenomena of the wire bonding process are considered using finite element simulation for the complex plastic deformation of the wire and reduced order models for the transient dynamics of the transducer, wire, substrate and bond formation. The model parameters such as the coefficients of friction between bond tool and wire and between wire and substrate were determined for aluminium and copper wire in experiments with a test rig specially developed for the requirements of heavy wire bonding. To reduce simulation time, for the finite element simulation a restart analysis and high performance computing is utilized. Detailed analysis of the bond formation showed, that the normal pressure distribution in the contact between wire and substrate has high impact on bond formation and distribution of welded areas in the contact area.","lang":"eng"}],"publication":"Microelectronics Reliability","volume":119,"user_id":"210","_id":"21436","page":"114077","status":"public","quality_controlled":"1","citation":{"short":"R.

Rivets for self-piercing riveting differ in their geometry, the material used, the condition of the material and their surface condition. To shorten the manufacturing process by omitting the heat treatment and the coating process, the authors have elaborated a concept for the use of stainless steel with high strain hardening as a rivet material. The focus of the present investigation is on the evaluation of the influences of the rivet’s geometry and material on its deformation behaviour. Conventional rivets of types P and HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted by means of multi-step joining tests for two material combinations comprising high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide a cross-section and the deformation behaviour of the different rivets is analysed on the basis of the measured changes in geometry and hardness. In parallel, an examination of the force-stroke curves provides further insights. It can be demonstrated that, besides the geometry, the material strength, in particular, has a significant influence on the deformation behaviour of the rivet. The strength of steel 1.4541 is seen to be too low for the joining task, while the strength of steel 1.3815 is sufficient, and hence the investigation confirms the capability of rivets made of 1.3815 for joining even challenging material combinations.","lang":"eng"}],"date_created":"2021-08-04T14:02:32Z","department":[{"_id":"157"}],"type":"book_chapter","keyword":["Self-piercing riveting","Lightweight design","Deformation behaviour","Stainless steel","High nitrogen steel"],"author":[{"full_name":"Uhe, Benedikt","first_name":"Benedikt","last_name":"Uhe","id":"38131"},{"last_name":"Kuball","first_name":"Clara-Maria","full_name":"Kuball, Clara-Maria"},{"last_name":"Merklein","first_name":"Marion","full_name":"Merklein, Marion"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246"}],"title":"Self-Piercing Riveting Using Rivets Made of Stainless Steel with High Strain Hardening","year":"2021","publication_status":"published","date_updated":"2026-02-27T10:40:39Z","language":[{"iso":"eng"}],"doi":"10.1007/978-3-030-75381-8_124"},{"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://digital-library.theiet.org/content/books/10.1049/pbcs072e_ch14"}],"doi":"10.1049/pbcs072e_ch14","author":[{"full_name":"Schröder, Dominik","last_name":"Schröder","first_name":"Dominik"},{"id":"38240","first_name":"Sven","last_name":"Lange","full_name":"Lange, Sven"},{"last_name":"Hangmann","first_name":"Christian","full_name":"Hangmann, Christian"},{"full_name":"Hedayat, Christian","last_name":"Hedayat","first_name":"Christian"}],"publication_identifier":{"isbn":["9781839530494","9781839530500"]},"title":"Far-field prediction combining simulations with near-field measurements for EMI assessment of PCBs","year":"2020","publication_status":"published","date_updated":"2022-01-06T06:55:03Z","date_created":"2021-03-18T13:49:49Z","department":[{"_id":"485"}],"keyword":["Huygens' box","NF-to-FF transformation","efficient FF radiation model","FF behaviour","EMI assessment","PCB","near-field measurements","efficient radiation model","far-field behaviour","RF design process","far-field prediction","Huygens'box principle","fullwave simulation","electronic system radiation","equivalent radiation source","electromagnetic simulation tool","near-field scan data","EM compatibility failure reduction"],"type":"book_chapter","publication":"Tensorial Analysis of Networks (TAN) Modelling for PCB Signal Integrity and EMC Analysis","related_material":{"record":[{"status":"public","id":"21542","relation":"other"}]},"abstract":[{"lang":"eng","text":"Using near-field (NF) scan data to predict the far-field (FF) behaviour of radiating electronic systems represents a novel method to accompany the whole RF design process. This approach involves so-called Huygens' box as an efficient radiation model inside an electromagnetic (EM) simulation tool and then transforms the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box principle and the NF-to-FF transformation are briefly presented. The NF is measured on the Huygens' box around a device under test using anNF scanner, recording the magnitude and phase of the site-related magnetic and electric components. A comparison between a fullwave simulation and the measurement results shows a good similarity in both the NF and the simulated and transformed FF.Thus, this method is applicable to predict the FF behaviour of any electronic system by measuring the NF. With this knowledge, the RF design can be improved due to allowing a significant reduction of EM compatibility failure at the end of the development flow. In addition, the very efficient FF radiation model can be used for detailed investigations in various environments and the impact of such an equivalent radiation source on other electronic systems can be assessed."}],"_id":"21542","publisher":" The Institution of Engineering and Technology (IET)","edition":"1","page":"315-346 (32)","user_id":"38240","status":"public","place":"Croyton, UK","citation":{"apa":"Schröder, D., Lange, S., Hangmann, C., &#38; Hedayat, C.

Consistent with schemata theory, starting with in-depth reading allows readers to acquire more substantial prior content schemata, which are representa-tive for the literature corpus and useful in the following skimming process. To this end, we develop a prototype that identifies the influential papers from a set of PDFs, which is illustrated in a case study in the IT business value domain.

From the perspective of potential students, these programmes are highly attractive because they combine types of learning that used to be largely separate at an institutional level: vocational and academic learning. In training-integrated dual study programmes, different institutional contexts, governance regimes, teaching styles and learning environments make bridging these two worlds of learning a challenge for both educators and learners. However, these programmes also allow leeway for didactic innovation, through the cooperation of different types of educational institutions and through new ways of using available didactic methods, and for establishing a new relationship between higher education (HE) and vocational education and training (VET). This paper positions training-integrated dual study programmes as an object of design-based research (DBR). By developing and using an extended model for the pedagogic development of HEIs, “pädagogische Hochschulentwicklung” (Brahm, Jenert, &amp; Euler, 2016a, p. 19; Euler, 2013, p. 360), the paper systematically identifies generic educational problems in these hybrids. Based on a literature review, this paper classifies and explains the design challenges at the level of the learning environment, the study programme and the organisation. The challenges revolve mainly around the cooperation and integration of HE and VET. The paper concludes with an outlook on future DBR projects designing dual studies."}],"issue":"1","publication":"EDeR.

The key design principle of SMBO is a substitution of the true objective function by a surrogate, which is used to propose the point(s) to be evaluated next. SMBO algorithms are intrinsically modular, leaving the user with many important design choices. Significant research efforts go into understanding which settings perform best for which type of problems. Most works, however, focus on the choice of the model, the acquisition function, and the strategy used to optimize the latter. The choice of the initial sampling strategy, however, receives much less attention. Not surprisingly, quite diverging recommendations can be found in the literature. We analyze in this work how the size and the distribution of the initial sample influences the overall quality of the efficient global optimization (EGO) algorithm, a well-known SMBO approach. While, overall, small initial budgets using Halton sampling seem preferable, we also observe that the performance landscape is rather unstructured. We furthermore identify several situations in which EGO performs unfavorably against random sampling. Both observations indicate that an adaptive SMBO design could be beneficial, making SMBO an interesting test-bed for automated algorithm design."}],"extern":"1","date_created":"2023-11-14T15:58:53Z","keyword":["continuous black-box optimization","design of experiments","initial design","sequential model-based optimization"],"type":"conference","department":[{"_id":"819"}],"title":"Initial Design Strategies and Their Effects on Sequential Model-Based Optimization: An Exploratory Case Study Based on BBOB","year":"2020","publication_identifier":{"isbn":["978-1-4503-7128-5"]},"author":[{"id":"102979","full_name":"Bossek, Jakob","orcid":"0000-0002-4121-4668","first_name":"Jakob","last_name":"Bossek"},{"first_name":"Carola","last_name":"Doerr","full_name":"Doerr, Carola"},{"full_name":"Kerschke, Pascal","last_name":"Kerschke","first_name":"Pascal"}],"date_updated":"2023-12-13T10:44:01Z","publication_status":"published","language":[{"iso":"eng"}],"series_title":"GECCO ’20","doi":"10.1145/3377930.3390155"}]
