While this typically\r\nworks well for the considered scenario, the models often rely\r\non unrealistic assumptions or on knowledge that is not available\r\nin practice (e.g., a priori knowledge).\r\n\r\nWe propose a novel deep reinforcement learning approach that\r\nlearns how to best coordinate services and is geared towards\r\nrealistic assumptions.

Rather than\r\ndefining a complex model or an algorithm how to achieve an\r\nobjective, our model-free approach adapts to various objectives\r\nand traffic patterns. An agent is trained offline without expert\r\nknowledge and then applied online with minimal overhead.

The tension between the two megatrends of digitization and servitization leads to new hybrid market offerings, so-called smart services. Corresponding business models and value networks fundamentally differ from traditional ones. Developing smart services requires an advanced management of business models and new competences in young disciplines, while their provision requires new internal and external organizational structures or processes. To strengthen their competitive position, manufacturing companies need to extend their business model portfolios and adapt their value networks. However, the highly complex transformation of value creation especially challenges small and medium-sized companies due to limited competences and resources. They must consider opening their boundaries and collaborating with partners. In this chapter, we introduce a basic framework for designing smart services and present a methodology for the planning of a smart service business integrating external partners. The methodology is structured into five phases: Examination of smart service portfolio, analysis of business models and environment, business model portfolio planning, competence identification and analysis, and value creation planning. The methodology is explained by an example on cable marker printers."}],"editor":[{"last_name":"Barlatier","full_name":"Barlatier, Pierre-Jean","first_name":"Pierre-Jean"},{"last_name":"Mention","full_name":"Mention, Anne-Laure","first_name":"Anne-Laure"}],"status":"public"},{"intvolume":"         1","citation":{"ama":"Otroshi M, Rossel M, Meschut G.

As a consequence of the resulting need for multi-material design, mechanical joining technologies become increasingly important. Mechanical joining allows for the combination of dissimilar materials, while thermic joining techniques reach their limits. Self-piercing riveting enables the joining of dissimilar materials by using semi-tubular rivets as mechanical fasteners. The rivet production, however, is costly and time-consuming, as the rivets generally have to be hardened, tempered and coated after forming, in order to achieve an adequate strength and corrosion resistance. A promising approach to improve the efficiency of the rivet manufacturing is the use of high-strength high nitrogen steel as rivet material because these additional process steps would not be necessary anymore. As a result of the comparatively high nitrogen content, such steels have various beneficial properties like higher strength, good ductility and improved corrosion resistance. By cold bulk forming of high nitrogen steels high-strength parts can be manufactured due to the strengthening which is caused by the high strain hardening. However, high tool loads thereby have to be expected and are a major challenge during the production process. Consequently, there is a need for appropriate forming strategies. This paper presents key aspects concerning the process design for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel. The aim is to produce the rivets in several forming stages without intermediate heat treatment between the single stages. Due to the high strain hardening of the material, a two stage forming concept will be investigated. Cup-backward extrusion is chosen as the first process step in order to form the rivet shank without forming the rivet foot. Thus, the strain hardening effects in the area of the rivet foot are minimized and the tool loads during the following process step can be reduced. During the second and final forming stage the detailed geometry of the rivet foot and the rivet head is formed. In this context, the effect of different variations, for example concerning the final geometry of the rivet foot, on the tool load is investigated using multistage numerical analysis. Furthermore, the influence of the process temperature on occurring stresses is analysed. Based on the results of the investigations, an adequate forming strategy and a tool concept for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel are presented.","lang":"eng"}],"status":"public","_id":"19976","department":[{"_id":"157"}],"series_title":"Procedia Manufacturing","user_id":"53912","keyword":["high nitrogen steel","self-piercing riveting","joining by forming","bulk forming","tool design"],"language":[{"iso":"eng"}],"quality_controlled":"1","publication_status":"published","year":"2020","page":"280-285","intvolume":"        50","citation":{"apa":"Kuball, C.-M., Uhe, B., Meschut, G., &#38; Merklein, M.

In the present investigation, an improved rivet geometry is developed, which permits the reliable joining of two material combinations that could only be joined by two different rivet geometries up until now. Material combination 1 consists of high-strength steel on both sides, while material combination 2 comprises aluminium on the punch side and high-strength steel on the die side. The material flow and the stress and strain conditions prevailing during the joining process are analysed by means of numerical simulation.

These techniques allow for the joining of dissimilar materials and thus enable multi-material design, while thermic joining methods reach their limits. Semi-tubular self-piercing riveting is an important mechanical joining technology. The rivet production, however, is costly and time-consuming, as the process consists of several process steps including the heat treatment and coating of the rivets in order to achieve an adequate strength and corrosion resistance. The use of high nitrogen steel as rivet material leads to the possibility of reducing process steps and hence increasing the efficiency of the process. However, the high tool loads being expected due to the high strain hardening of the material are a major challenge during the rivet production. Thus, there is a need for appropriate forming strategies, such as the manufacturing of the rivets at elevated temperatures. Prior investigations led to the conclusion that forming already at 200 °C results in a distinct reduction of the yield strength. To create a deeper understanding of the forming behaviour of high nitrogen steel at elevated temperatures, compression tests were conducted in a temperature range between room temperature and 200 °C. The determined true stress – true strain curves are the basis for the further process and tool design of the rivet production. Another key factor for the rivet manufacturing at elevated temperatures is the influence of the process temperature on the tribological conditions. For this reason, ring compression tests at room temperature and 200 °C are carried out. The friction factors are determined on the basis of calibration curves resulting from the numerical analysis of the ring compression process. The investigations indicate that the friction factor at 200 °C is significantly higher compared to room temperature. This essential fact has to be taken into account for the process and tool design for the rivet production using high nitrogen steel."}],"status":"public","date_updated":"2026-02-27T10:45:08Z","volume":1,"date_created":"2020-10-12T08:23:27Z","title":"Influence of the process temperature on the forming behaviour and the friction during bulk forming of high nitrogen steel","doi":"10.1016/j.jajp.2020.100023","quality_controlled":"1","publication_status":"published","year":"2020","intvolume":"         1","citation":{"bibtex":"@book{Kuball_Jung_Uhe_Meschut_Merklein_2020, series={Journal of Advanced Joining Processes}, title={Influence of the process temperature on the forming behaviour and the friction during bulk forming of high nitrogen steel}, volume={1}, DOI={<a href=\"https://doi.org/10.1016/j.jajp.2020.100023\">10.1016/j.jajp.2020.100023</a>}, number={100023}, year={2020}, collection={Journal of Advanced Joining Processes} }","mla":"Kuball, Clara-Maria, et al., editors. <i>Influence of the Process Temperature on the Forming Behaviour and the Friction during Bulk Forming of High Nitrogen Steel</i>. 100023, 2020, doi:<a href=\"https://doi.org/10.1016/j.jajp.2020.100023\">10.1016/j.jajp.2020.100023</a>.","short":"C.-M.

First, research strands are disconnected, emphasizing either exploration or exploitation of service innovation, despite an organizations’ need to accelerate innovation cycles of exploring and exploiting services. Second, a new framework for ambidextrous service innovation is provided, inspired by the dynamism and generative mechanisms of the ontologically related concept of organizational routines. The framework adopts the perspective of a mutually constitutive relationship between exploring new and exploiting current resources, activities, and knowledge. The findings remedy the scattered literature through a coherent perspective on service innovation that responds to organizations’ needs and guides future research.","lang":"eng"}],"status":"public","date_updated":"2022-01-06T07:04:18Z","author":[{"last_name":"Wolf","full_name":"Wolf, Verena","id":"23633","first_name":"Verena"}],"date_created":"2019-05-08T13:39:19Z","title":"Ambidexterity in Service Innovation Research: A Systematic Literature Review","conference":{"name":"14th International Conference on Wirtschaftsinformatik","location":"Siegen, Germany"},"quality_controlled":"1","year":"2019","place":"Siegen, Germany","citation":{"bibtex":"@inproceedings{Wolf_2019, place={Siegen, Germany}, title={Ambidexterity in Service Innovation Research: A Systematic Literature Review}, booktitle={Proceedings of the 14th International Conference on Wirtschaftsinformatik}, author={Wolf, Verena}, year={2019} }","short":"V.

To put VMs and CNs together, an orchestration framework that can chain services across distributed and heterogeneous domains is required. To this end, we implemented a framework by extending and consolidating state-of-the-art tools and technologies originated from Network Function Virtualization (NFV), Software-defined Networking (SDN) and cloud computing environments. This framework chains services provisioned across Kubernetes and OpenStack domains.

In a multi-method study that includes conceptual research and qualitative data from in-depth interviews, we conceptualize “smart service” and “smart service systems” based on using smart products as boundary objects that integrate service consumers’ and service providers’ resources and activities. Smart products allow both actors to retrieve and to analyze aggregated field evidence and to adapt service systems based on contextual data. We discuss the implications that the introduction of smart service systems have for foundational concepts of service science and conclude that smart service systems are characterized by technology-mediated, continuous, and routinized interactions.","lang":"eng"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_id":"53575","file_name":"Beverungen_et_al-Conceptualizing_Smart_Service_Systems.pdf","access_level":"closed","file_size":599681,"date_created":"2024-04-18T12:53:07Z","creator":"dabe","date_updated":"2024-04-18T12:53:07Z"}],"publication":"Electronic Markets","keyword":["Boundary object","Internet of things","Service science","Smart products","Smart service"],"ddc":["380"],"language":[{"iso":"eng"}],"year":"2019","quality_controlled":"1","title":"Conceptualizing smart service systems","publisher":"SpringerNature","date_created":"2018-10-12T08:24:45Z","status":"public","type":"journal_article","article_type":"original","file_date_updated":"2024-04-18T12:53:07Z","_id":"4684","project":[{"grant_number":"645751","_id":"1070","name":"RISE_BPM: Propelling Business Process Management by Research and Innovation Staff Exchange","call_identifier":"MSCA-RISE-2014"}],"department":[{"_id":"195"}],"user_id":"59677","page":"7-18","intvolume":"        29","jel":["L8"],"citation":{"chicago":"Beverungen, Daniel, Oliver Müller, Martin Matzner, Jan Mendling, and Jan vom Brocke. “Conceptualizing Smart Service Systems.” <i>Electronic Markets</i> 29 (2019): 7–18. <a href=\"https://doi.org/10.1007/s12525-017-0270-5\">https://doi.org/10.1007/s12525-017-0270-5</a>.","ieee":"D.

Die Betriebsparamter der Ultraschallsysteme werden empirisch ermittelt, da derzeit keine systematische Analyse der Wechselwirkung zwischen Ultraschallwandler und Schallfeld sowie kein Verfahren zur Messung der Kavitationsaktivität ohne zusätzlichen Sensor existieren. Auf Basis einer experimentellen Analyse des betrachteten sonochemischen Reaktors wird ein Finite-Elemente-Modell aufgebaut, das die Wechselwirkung zwischen Schallfeld und Ultraschallwandler berücksichtigt. Die modellbasierte Analyse zeigt, dass wegen der akustischen Eigenschaften des Autoklavs nur direkt an der Sonotrode Kavitation entsteht. Die Wechselwirkung zwischen Ultraschallwandler und Schallfeld ermöglicht Aussagen über das Schallfeld und die Kavitationsaktivität auf Basis der Rückwirkung auf den Ultraschallwandler. Die lineare Schalldruckverteilung ermöglicht eine Prognose über die Verteilung von Kavitationszonen. Das beschriebene Modell liefert wertvolle Erkenntnisse für die Auslegung, Analyse und Skalierung sonochemischer Reaktoren. Auf Grund der rauen Prozessrandbedingungen ist die Applikation von Sensoren zur Überwachung der Kavitationsaktivität in vielen sonochemischen Prozessen nicht möglich. Zur prozessbegleitenden Messung der Kavitationsaktivität wird ein Verfahren entwickelt, das die Bewertung der Kavitationsaktivität durch Auswertung der Rückwirkung auf den Ultraschallwandler erlaubt. Das Messverfahren ermöglicht eine vorhersagbare und reproduzierbare Durchführung kavitationsbasierter Prozesse und stellt eine wichtige Erweiterung für bestehende und neue Ultraschallsysteme dar.","lang":"eng"}],"type":"dissertation","title":"Modellierung und experimentelle Charakterisierung der Wechselwirkung zwischen Ultraschallwandler und Flüssigkeit in kavitationsbasierten Prozessen","author":[{"last_name":"Bornmann","full_name":"Bornmann, Peter","first_name":"Peter"}],"date_created":"2019-05-27T10:29:53Z","publisher":"Shaker","date_updated":"2023-09-15T12:23:55Z","citation":{"short":"P.

Through interviews with both owners of animal companions and providers of services for animal companions, this study explores typical constellations and characteristics of the three relationships in this service triad. In line with balance theory, the results show that four distinct types of triadic relationships exist in services for animal companions: the harmonious, the dysfunctional, the challenging, and the doubtful triad.

Copper wire is increasingly replacing the well-established aluminium wire because of its superior electrical, thermal and mechanical properties. Copper wire processes differ significantly from aluminium processes and are more sensitive to disturbances, which reduces the range of parameter values suitable for a stable process. Disturbances can be compensated by an adaption of process parameters, but finding suitable parameters manually is difficult and time-consuming. This paper presents a physical model of the ultrasonic wire bonding process including the friction contact between tool and wire. This model yields novel insights into the process. A prototype of a multi-objective optimizing bonding machine (MOBM) is presented. It uses multi-objective optimization, based on the complete process model, to automatically select the best operating point as a compromise of concurrent objectives."}],"date_created":"2019-05-27T10:27:45Z","author":[{"first_name":"Andreas","last_name":"Unger","full_name":"Unger, Andreas"},{"full_name":"Hunstig, Matthias","last_name":"Hunstig","first_name":"Matthias"},{"last_name":"Meyer","full_name":"Meyer, Tobias","first_name":"Tobias"},{"full_name":"Brökelmann, Michael","last_name":"Brökelmann","first_name":"Michael"},{"first_name":"Walter","full_name":"Sextro, Walter","id":"21220","last_name":"Sextro"}],"volume":"Vol. 2018, No. 1, pp. 000572-000577.","date_updated":"2020-05-07T05:33:56Z","doi":"10.4071/2380-4505-2018.1.000572","title":"Intelligent Production of Wire Bonds using Multi-Objective Optimization – Insights, Opportunities and Challenges","quality_controlled":"1","citation":{"ama":"Unger A, Hunstig M, Meyer T, Brökelmann M, Sextro W.

Patients review the subjectively experienced quality of medical services supplied to them and publish an overall rating on the Internet, where quantitative grades and qualitative texts come together. On the one hand, these new possibilities reduce the imbalance of power between health care providers and patients, but on the other hand, they can also damage the usually very intimate relationship between health care providers and patients. Review websites must meet these requirements with a high level of responsibility and service quality. In this paper, we look at the situation in Lithuania: Especially, we are interested in the available possibilities of evaluation and interaction, and the quality of a particular review website measured against the available data.

Aligning ourselves to the ongoing critical discussions of interiorization in psychology, we explore the crucial notion of space by highlighting language as sociocultural and dialogical activity performed by other-oriented individuals. We discuss space in terms of the “language spacetime”, a symbolic, embodied formation of mutually positioned speaking and listening selves. This leads beyond the “inside-outside” container metaphor and allows for a reformulation of interiorization. Interiorization is conceptualized as a continuous series of different, though mutually related movements between self and other and self and self that lead to and are supported by specific formations in language activity: reversion, transposition, and decoupling. Along a short passage of a video-based interview, we trace the reversion of dialogical positions within the addressivity constellation of the two interlocutors, their interactive creation of a heterotopic spacetime, and the decoupling of one speaker's psychological activity from the concrete here-and-now and the present other by moving and acting into this new sphere. Interiorization appears as a movement at the border of past, present, and possible future(s).","lang":"eng"}],"publisher":"Elsevier BV","date_created":"2022-06-24T14:41:20Z","title":"Reconsidering interiorization: Self moving across language spacetimes","year":"2018","_id":"32158","user_id":"42165","department":[{"_id":"424"}],"type":"journal_article","status":"public","date_updated":"2022-07-18T09:21:16Z","author":[{"last_name":"Bertau","full_name":"Bertau, Marie-Cécile","first_name":"Marie-Cécile"},{"last_name":"Karsten","id":"53917","full_name":"Karsten, Andrea","first_name":"Andrea"}],"volume":49,"doi":"10.1016/j.newideapsych.2017.12.001","publication_status":"published","publication_identifier":{"issn":["0732-118X"]},"citation":{"ama":"Bertau M-C, Karsten A.
