- PublikationDetermination of weights for multiobjective combinatorial optimization in incident management with an evolutionary algorithm(IEEE, 2023) Gachnang, Phillip; Ehrenthal, Joachim; Telesko, Rainer; Hanne, Thomas [in: IEEE Access]Incident management in railway operations includes dealing with complex and multiobjective planning problems with numerous constraints, usually with incomplete information and under time pressure. An incident should be resolved quickly with minor deviations from the original plans and at acceptable costs. The problem formulation usually includes multiple objectives relevant to a railway company and the employees involved in controlling operations. Still, there is little established knowledge and agreement regarding the relative importance of objectives such as expressed by weights. Due to the difficulties in assessing weights in a multiobjective context directly involving decision makers, we elaborate on the autoconfiguration of weighted fitness functions based on nine objectives used in a related Integer Linear Programming (ILP) problem. Our approach proposes an evolutionary algorithm and tests it on real-world railway incident management data. The proposed method outperforms the baseline, where weights are equally distributed. Thus, the algorithm shows the capability to learn weights in future applications based on the priorities of employees solving railway incidents which is not yet possible due to an insufficient availability of real-life data from incident management. https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10339298&tag=101A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationService Dominant-Logic als Forschungsmethode(Springer, 2023) Ehrenthal, Joachim; Gruen, Thomas W.; Hofstetter, Joerg S.; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien. Digitale Innovation und digitale Transformation]Im digitalen Zeitalter wetteifern die Unternehmen darum, wie gut ihr Service die Bedürfnisse der Kundschaft erfüllt und Probleme löst. Sie intera- gieren dafür mit immer mehr Akteuren, um ihr Versprechen zu erfüllen. Ein für die Forschung in dieser „neuen“ Welt besonders geeigneter Ansatz ist die Service- Dominant Logic (SDL). Es gibt jedoch keine Leitlinien oder einen allgemein aner- kannten Rahmen für die systematische Durchführung von Forschungsarbeiten zur und mit der SDL. Um diese Lücke zu schließen, wird in diesem Kapitel der Einsatz der SDL in der Forschung untersucht und analysiert. Es gibt Empfehlungen für die Durchführung von SDL in der Forschung und schlägt einen Organisationsrahmen für angewandte Forschungsumgebungen und darüber hinaus vor.04A - Beitrag Sammelband
- PublikationEchtzeit Ressourcendisposition von Personal und Rollmaterial in der Eisenbahnbranche(Innosuisse, 2023) Ehrenthal, Joachim; Hanne, Thomas; Telesko, Rainer; Gachnang, PhillipZu wenig Personal und Rollmaterial, kurzfristig angesagte Arbeiten an der Infrastruktur mit den entsprechenden betrieblichen Behinderungen und Einschränkungen sowie kurzfristig auftretende Störungen prägen zurzeit die Berichterstattung über die Entwicklungen im öffentlichen Verkehr der Schweiz. Es ist absehbar, dass sich diese unbefriedigende Situation über eine längere Zeitspanne kaum massgeblich verbessern wird. Umso wichtiger ist es, vorhandene Ressourcen optimal einzusetzen und den zukünftigen Bedarf an Mitarbeitenden und Rollmaterial in den Griff zu kriegen. Die Fachhochschulen der Ostschweiz (OST) und der Nordwestschweiz FHNW entwickelten mit der Südostbahn (SOB), den luxemburgischen Eisenbahnen (CFL) und der Eisenbahn-Softwareherstellerin Qnamic eine zukunftsweisende Software zur Unterstützung der Eisenbahn-Disposition, um in Echtzeit über situationsspezifische Massnahmenpakete zur Störungsbehebung zu verfügen.05 - Forschungs- oder Arbeitsbericht

- PublikationDigitalizing the supply chain of clinical trials(SAGE, 2022) Antonuccio, Deborah; Buser, Lukas; Ehrenthal, Joachim; Maheswaran, Mugunthan; Schwarz, Philip [in: Journal of Information Technology Teaching Cases]Clinical trials investigate the effectiveness and safety of new medications and treatments before market introduction. Data quality and speed are keys to clinical trials success, together with the overall time to bring innovative medicines to patients in need. Cutting edge trials programs rely on data from participant devices to track and monitor health. The supply chain of these devices, and leveraging supply chain data to improve it, have become critical to clinical trials success. This case presents how a small Business Unit specialized improved their device supply chain by digitizing supply chain processes and leveraging supply chain data. Set in the Swiss pharmaceuticals industry, case provides rich insights on data collection and exchange in clinical trials supply chains.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationRecommendations for conducting service-dominant logic research(Springer, 2020) Ehrenthal, Joachim; Gruen, Thomas W.; Hofstetter, Joerg S.; Dornberger, Rolf [in: New trends in business information systems and technology]In the digital age, companies compete on how well their service meets customer needs and solves customer problems, interacting with ever more actors to fulfill their promise. A well-suited mid-range theory to conduct research in this “new” world is service-dominant (S-D) logic. However, there are no guidelines or a commonly agreed framework for systematically conducting S-D logic research. To fill this gap, this chapter reviews and analyzes the use of S-D logic in research. It provides recommendations for conducting S-D logic in research and proposes an organizing framework for applied research settings and beyond.04A - Beitrag Sammelband
- PublikationRecommendations for conducting service-dominant logic based research(Springer, 2019) Ehrenthal, Joachim; Gruen, Thomas W.; Hofstetter, Joerg S.; Dornberger, Rolf [in: New trends in business information systems and technology. Digital innovation and digital business transformation]While Service-Dominant logic (SDL) has been the basis for research publications in many journals, anecdotal evidence suggests that there is growing resistance to using SDL because some reviewers consider it to be unviable for rigorous research. As a remedy, researchers, editors, and reviewers are in need for clear criteria on what makes good quality SDL research. Our study aims to address this problem, and it examines how SDL has been successfully and unsuccessfully used in research—including methods, processes, and approaches to apply & integrate SDL in research studies—in order to determine a set of quality criteria for researchers and practitioners to better use and benefit from SDL.04A - Beitrag Sammelband
