Andererseits existieren theoretisch-konzeptionelle Ans{\"a}tze zur Gestaltung digitaler Lehr- und Lernarrangements, die jedoch 1) oft Gefahr laufen, an den realen Bed{\"u}rfnissen der Praxis „vorbei" zu gehen und 2) zumeist nicht konkret Virtual-Reality bzw. damit verbundene Lehr- und Lernumgebungen adressieren. In dieser Folge sind Best-Practice Beispiele basierend auf erfolgreichen Umsetzungsvorhaben, die nachfolgenden Projekten als „Wegweiser" dienen k{\"o}nnten, {\"a}ußerst rar. Der Beitrag setzt an dieser Stelle an: basierend auf zwei real existierenden betrieblichen Anwendungsf{\"a}llen aus den Bereichen Natursteinbearbeitung sowie Einzel- und Sondermaschinenbau werden Herausforderungen und L{\"o}sungswege des Erstellungsprozesses von Virtual-Reality gest{\"u}tzten (Lehr- und Lern-)R{\"a}umen beschrieben.

It assumes that individual learning experiences and results could generally be improved when personal learning preferences are considered. To do justice to the complexity of the personalisation possibilities of teaching and learning processes, we illustrate the components of learning and teaching in the digital environment and their interdependencies in an initial model. Furthermore, in a pre-study, we investigate the relationships between the learner's ability to (digital) self-organise, the learner's prior- knowledge learning in different variants of mode and learning outcomes as one part of this model.

Several factors influence knowledge transfer, e.g., the complexity of engineering tasks or the competence of employees, which can decrease the efficiency and effectiveness of knowledge transfers in product engineering. Hence, improving those knowledge transfers obtains great potential, especially against the backdrop of experienced employees leaving the company due to retirement, so far, research results show, that the knowledge transfer velocity can be raised by following the Knowledge Transfer Velocity Model and implementing so-called interventions in a product engineering context. In most cases, the implemented interventions have a positive effect on knowledge transfer speed improvement. In addition to that, initial theoretical findings describe factors influencing the quality of knowledge transfers and outline a setting to empirically investigate how the quality can be improved by introducing a general description of knowledge transfer reference situations and principles to measure the quality of knowledge artifacts. To assess the quality of knowledge transfers in a product engineering context, the Knowledge Transfer Quality Model (KTQM) is created, which serves as a basis to develop and implement quality-dependent interventions for different knowledge transfer situations. As a result, this paper introduces the specifications of eight situation-adequate interventions to improve the quality of knowledge transfers in product engineering following an intervention template. Those interventions are intended to be implemented in an industrial setting to measure the quality of knowledge transfers and validate their effect.}, language = {en} } @incollection{GronauWeberWanderetal.2022, author = {Gronau, Norbert and Weber, Edzard and Wander, Paul and Ullrich, Andr{\´e}}, title = {A regional remanufacturing network approach}, series = {Digitization of the work environment for sustainable production}, booktitle = {Digitization of the work environment for sustainable production}, editor = {Plapper, Peter}, publisher = {GITO Verlag}, address = {Berlin}, isbn = {978-3-95545-407-4}, doi = {10.30844/WGAB_2022_8}, pages = {145 -- 170}, year = {2022}, abstract = {Manufacturing companies still have relatively few points of contact with the circular economy. Especially, extending life time of whole products or parts via remanufacturing is an promising approach to reduce waste. However, necessary cost-efficient assessment of the condition of the individual parts is challenging and assessment procedures are technically complex (e.g., scanning and testing procedures). Furthermore, these assessment procedures are usually only available after the disassembly process has been completed. This is where conceptualization, data acquisition and simulation of remanufacturing processes can help. One major constraining aspect of remanufacturing is reducing logistic efforts, since these also have negative external effects on the environment. Thus regionalization is an additional but in the end consequential challenge for remanufacturing. This article aims to fill a gap by providing an regional remanufacturing approach, in particular the design of local remanufacturing chains. Thereby, further focus lies on modeling and simulating alternative courses of action, including feasibility study and eco-nomic assessment.}, language = {en} } @incollection{Gronau2022, author = {Gronau, Norbert}, title = {Errors in the process of modeling business processes}, series = {Business modeling and software design : 12th International Symposium, BMSD 2022, Fribourg, Switzerland, June 27-29, 2022, proceedings}, volume = {453}, booktitle = {Business modeling and software design : 12th International Symposium, BMSD 2022, Fribourg, Switzerland, June 27-29, 2022, proceedings}, editor = {Shishkov, Boris}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {978-3-031-11509-7}, doi = {10.1007/978-3-031-11510-3_13}, pages = {221 -- 229}, year = {2022}, abstract = {Process models are the basic ingredient for many attempts to improve business processes.
