Nearly two decades ago, the service system concept was introduced as a foundational abstraction in service research, drawing on ideas from the service-dominant logic (S-D logic) of marketing. Despite its widespread adoption in service research, particularly in the IS discipline, the service system concept lacks a solid theoretical foundation. This has resulted in conceptual ambiguity and overlap with related constructs, such as service ecosystems. Moreover, it has largely remained a static analytical lens, insufficiently capturing dynamic service phenomena, including value co-creation and co-destruction, as well as the emergence of institutional arrangements. To address these limitations, we propose Luhmann’s systems theory (LST) as a robust framework for conceptualizing service systems as autopoietic (self-creating) systems, in which communication serves as the fundamental mechanism that drives value co-creation. We derive five theoretical propositions from this re-conceptualization that clarify conceptual ambiguity and allow researchers to explore dynamic service phenomena in greater depth. Given LST’s general approach, our conceptualization provides a theoretically grounded, interdisciplinary foundation for advancing service research.}}, author = {{Beverungen, Daniel and Poeppelbuss, Jens and Hemmrich, Simon and Iqbal, Taskeen}}, issn = {{1019-6781}}, journal = {{Electronic Markets}}, keywords = {{Service system, Service ecosystem, Systems theory, Service research}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Service through communication—Conceptualizing service systems with Luhmann’s systems theory}}}, doi = {{10.1007/s12525-026-00889-w}}, volume = {{36}}, year = {{2026}}, } @inproceedings{65836, author = {{Fichtler, Timm and Petzke, Lisa Irene and Grigoryan, Khoren and Koldewey, Christian and Dumitrescu, Roman}}, booktitle = {{Proceedings of the Annual Hawaii International Conference on System Sciences}}, issn = {{2572-6862}}, publisher = {{Hawaii International Conference on System Sciences}}, title = {{{Enhancing Product Management Performance through Digitalization: Advantages, Challenges, Design Fields}}}, doi = {{10.24251/hicss.2026.478}}, year = {{2026}}, } @article{65845, author = {{Kattenstroth, Fiona and Kranz, Michael and Hunger, Sebastian and Withot, Dennis and Hovemann, Aschot and Dumitrescu, Roman}}, issn = {{1877-0509}}, journal = {{Procedia Computer Science}}, pages = {{586--595}}, publisher = {{Elsevier BV}}, title = {{{Towards a digital factory twin: systematization of material flow simulation use cases}}}, doi = {{10.1016/j.procs.2026.02.100}}, volume = {{277}}, year = {{2026}}, } @article{65838, author = {{Rasor, Anja and Petzke, Lisa Irene and Koldewey, Christian and Dumitrescu, Roman}}, issn = {{2212-8271}}, journal = {{Procedia CIRP}}, pages = {{239--244}}, publisher = {{Elsevier BV}}, title = {{{Identifying Cost Drivers in Circular Business Model Planning: Insights from an Explorative Interview Study}}}, doi = {{10.1016/j.procir.2026.05.041}}, volume = {{140}}, year = {{2026}}, } @article{65840, author = {{Grigoryan, Khoren and Bauer, Eliana and Fichtler, Timm and Asmar, Laban and Kühn, Arno and Dumitrescu, Roman}}, issn = {{2212-8271}}, journal = {{Procedia CIRP}}, pages = {{916--921}}, publisher = {{Elsevier BV}}, title = {{{Design Principles and Process Model for Planning Data Analytics in Product Management}}}, doi = {{10.1016/j.procir.2026.05.154}}, volume = {{140}}, year = {{2026}}, } @article{65847, abstract = {{Simulating vibronic spectra is a central task in physical chemistry, offering insight into important properties of molecules. Recently, it has been experimentally demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are capable of performing these simulations. However, whether an actual GBS approach is required depends on the molecule under investigation. To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between theoretical approximations in physical chemistry and their photonic counterparts. Mapping these approximations into photonics, we show that for certain molecules the GBS approach is unnecessary. We place special emphasis on the linear coupling approximation, which in photonics corresponds to sampling from multiple coherent states. By implementing this approach in experiments, we demonstrate improved similarities over previously reported GBS results for formic acid and identify the particular attributes that a molecule must exhibit for this, and other approximations, to be valid.

We employ a two-phase solution framework: in phase 1, we solve the Charging Location and Electric Vehicle Scheduling Problem to generate vehicle schedules that are feasible for electric operation; in phase 2, these schedules serve as input to a multi-period transition planning model that minimizes the total cost of ownership while determining fleet replacement and charging infrastructure deployment. Our experiments show that schedules obtained from solving the integrated charging location and vehicle scheduling problem significantly outperform traditional methods, resulting in lower total cost of ownership. Additionally, transition plans reduce local emissions by up to 85% compared to a diesel-only scenario. We find that vehicle rotations with long distances and sufficient idle time are prioritized for electrification, enabling earlier emission reductions and cost savings. This highlights the importance of adopting vehicle scheduling tailored for electric buses, rather than relying on legacy diesel schedules.}}, author = {{Stumpe, Miriam and Rößler-von Saß, David and Kliewer, Natalia and Schryen, Guido}}, issn = {{2590-1982}}, journal = {{Transportation Research Interdisciplinary Perspectives}}, keywords = {{Electric bus, Multi-period planning, Electric vehicle scheduling, Charging infrastructure, Fleet replacement}}, publisher = {{Elsevier BV}}, title = {{{Impact of vehicle scheduling and strategic transition planning on zero-emission bus systems}}}, doi = {{10.1016/j.trip.2026.102008}}, volume = {{38}}, year = {{2026}}, } @article{61366, author = {{Paré, Guy and Wagner, Gerit and Tate, Mary and Schryen, Guido and Templier, Mathieu}}, issn = {{0960-085X}}, journal = {{European Journal of Information Systems}}, number = {{3}}, pages = {{555--579}}, publisher = {{Informa UK Limited}}, title = {{{Theorising Forward: Positioning Deductive Elaboration in the Information Systems Research Repertoire}}}, doi = {{10.1080/0960085x.2025.2550403}}, volume = {{35}}, year = {{2026}}, } @article{65865, abstract = {{Mathematical problem solving is a highly complex competence that needs to be supported throughout the learning process. This study examines the role of problem-solving heuristics among 73 sixth-grade students in a German secondary school (Gesamtschule). Specifically, we focus on the empirical relationship between the occurrence of heuristics, their suitability, and application, as well as their contribution to problem-solving success. To this end, we developed a heuristic training that introduced strategy keys (heuristic aid cards) accompanied by explanatory videos. By leveraging variations in the successful application of the heuristics between students and across multiple sessions (73 students in 4 training situations and 3 problems in a final test), we discover from regression models with student and task-fixed effects that a successful use of heuristics (i.e., an heuristic occurred, that heuristic had a high suitability regarding the problem, and it was applied correctly) leads to more successful mathematical problem solving. Regarding the underlying mechanism, we find that all dimensions of heuristic use (occurrence, suitability, and application of heuristics) are positively related to problem-solving success. When comparing the predictive capacity of all three aspects, we identified the correct application of heuristics as particularly conducive for better problem-solving success. In comparing the group of students with high to those with low initial math competence, we find no significant differences in the relationship between heuristic use and problemsolving success across achievement groups. Our results emphasize the crucial role of heuristic application in mathematical problem solving, which generally benefits students regardless of their overall math competence.}}, author = {{Herold-Blasius, Raja and Kleinschmidt, Hannah and Ziller, Conrad}}, journal = {{Journal für Mathematik-Didaktik}}, number = {{6}}, title = {{{Dimensions of Heuristic Use in Mathematical Problem Solving: Evidence from Early Secondary School Students}}}, doi = {{https://doi.org/10.1007/s13138-026-00270-6}}, volume = {{47}}, year = {{2026}}, }
