Initial Coin Offerings (ICOs) haben in jüngerer Vergangenheit ein bedeutsames Volumen im Rahmen der Emissionsfinanzierung erlangt. Sie basieren im Wesentlichen auf der Blockchain-Technologie, besitzen aber gleichzeitig typische Charakteristika von Finanzierungsinstrumenten aus der „analogen Welt“. Dieser Beitrag stellt die Varianten von Coins bzw. Token zunächst dar und zeigt darauf aufbauend die inhaltliche Verbindung zu analogen Finanzierungsinstrumenten und deren Systematisierung im Kontext der Unternehmensfinanzierung auf. Dies ermöglicht sowohl Investoren als auch Emittenten einen Vergleich zwischen diesen neuartigen Finanzierungsalternativen und den klassischen Finanzierungsinstrumenten. Unser Beitrag zeigt, dass auch in der Welt der Token der Dreigliederung aus Eigen-, Fremd- und Mezzaninfinanzierung im Hinblick auf ihre Ausgestaltung gefolgt werden kann, die Instrumente jedoch durchgehend der Außenfinanzierung zuzuordnen sind. Eine besondere hybride Stellung nehmen Nutzungstoken ein, die bereits aufgrund Ihrer Grundstruktur im Vorhinein nicht eindeutig einer Kapitalart zugeordnet werden können.
Adaptation of the business model canvas template to develop business models for the circular economy
(2021)
The Business Model Canvas as a template for strategic management serves the development of new or the documentation of existing linear business models. However, the change towards a Circular Economy requires new value creation structures and thus changed business models. To develop business models for circular economies, it is necessary to adapt the existing template, since the actors involved along the value chain take on changed roles. In the context of this paper, a template is presented, based on the existing Business Model Canvas, which allows to develop and document business models for a Circular Economy.
Die zunehmende Technologie- und Produktkomplexität führen dazu, dass sich immer mehr Unternehmen für ihre F&E mit externen Organisationen vernetzen. So entstehen interorganisationale F&E-Projekte, welche temporäre Organisationen darstellen. Forschungsfragen zu diesen Projekten sind u.a. hinsichtlich der Praktiken und Verhaltensregeln offen. Über ein kulturbewusstes Projektmanagement können kooperations- und innovationsförderliche Praktiken und Verhaltensregeln aufgebaut werden, die für diese F&E-Projekte essenziell sind. So ist die Forschungsfrage dieses Beitrags, wie ein projektkulturbewusstes Management interorganisationaler F&E-Projekte erfolgen kann. Dafür wird auf Basis der theoretischen Grundlagen zum F&E-Projektmanagement, zu menschlichen Handlungssystemen und Ebenen der Zusammenarbeit, zu Kultur und Verhalten ein projektkulturbewusstes Management-Modell entwickelt. Das Modell umfasst zwei Teile. Im ersten Teil wird der Bereich aufgezeigt, in welchem sich die Projektkultur entwickelt. Im zweiten Teil wird aufgezeigt, wie die Faktoren für ein wahrscheinlich kooperatives und innovatives Verhalten innerhalb dieses Bereiches gestaltet werden sollten.
Aufgrund der zunehmenden Individualisierung von Produkten mit hoher Variantenvielfalt stellt die aktive Integration von intelligenten Produkten in die Prozesssteuerung eine hilfreiche Möglichkeit zur Nutzung von Flexibilisierungs- und Rationalisierungspotenzialen in der Fertigung dar. In diesem Beitrag wird eine Methode zur Analyse und Bewertung der Einsatzpotenziale von Produktklassen mit unterschiedlichen Fähigkeiten vorgestellt und anhand eines praktischen Anwendungsfall evaluiert.
This study determines the correlation between industry-specific success patterns of Germany’s engineering industry and the business models applied within. In order to identify this correlation, the following objectives are addressed within the framework of this paper: (1) identification and description of business models used by Germany’s engineering industry; (2) analysis of industry-specific success patterns of Germany’s engineering industry by the usage of Key-Performance-Indicators (KPIs); and (3) determination of correlation between the KPIs and Germany’s engineering industry’s business models’ effectiveness. These objectives are mainly achieved by literature research and expert surveys. The findings highlight the KPIs (overall 41) that are relevant for the respective business models. This enables a better understanding of the interrelationships of the business model, in order to derive relevant conclusions. The paper contributes to the literature as it advances this field of research in Germany, and it is one of the first studies to examine the relationship between business models and industry-specific success patterns with relevant KPIs.
Reacting to ever-changing business environments, in the last decade complex systems of systems accomplished giant leaps forward leading to great technological flexibility. However, this dimension of flexibility is often limited by the rigidity of super-ordinated planning systems. Especially when hybrid teams of automated and human resources are in place, the dynamic assignment of tasks taking into account ergonomics remains a challenge. After exposing a gap in the state of the art on the topic, this paper presents an approach to include ergonomics in dynamic resource allocation models. Combining and complementing existing approaches, the presented method monitors the actual ergonomic burden of the resources during a shift and it provides a linear optimization model to steer the resource allocation process.
Autonomisierung von Shopfloor Management : Der Weg vom analogen zum autonomen Shopfloor Management
(2021)
Neue Technologien der Digitalisierung, Vernetzung und künstlichen Intelligenz werden zunehmend auch im Shopfloor Management (SFM) Einzug halten. Dieser Beitrag beschreibt in vier Stufen, wie sich das klassische SFM über das digitale SFM hin zu einem smarten und autonomen SFM entwickeln könnte. Darauf aufbauend wird diskutiert, welche Auswirkungen der Einsatz dieser neuen Technologien auf die operative Gestaltung der Durchführung eines SFM hätte und welche Konsequenzen somit auf Mitarbeiter und Führungskräfte zukommen würden.*)
Interkulturelles Management
(2021)
Kultur lässt sich beschreiben als „kollektive Programmierung des Geistes, die die Mitglieder einer Gruppe oder Kategorie von Menschen von anderen unterscheidet“ (Hofstede/Hofstede/Minkov, S.6). Die Muster des Glaubens, Denkens, Fühlens und Handelns, die diese mentalen Programme oder kulturellen Denkweisen ausmachen, werden von den Gruppenmitgliedern im Rahmen ihres Sozialisierungsprozesses erlernt. Sie sind die gemeinsamen „ungeschriebenen Regeln“, wie Dinge in diesem sozialen Umfeld gehandhabt werden (vgl. Hofstede/Hofstede/Minkov, S.6). Die Art und Weise, wie sich Menschen in einer bestimmten Kultur verhalten, ihre Praktiken und Normen, ist daher nicht willkürlich, sondern wird in hohem Maße von diesen erlernten Prinzipien und Werten beeinflusst. Das Wissen über eine Kultur ermöglicht es, Reaktionen ihrer Mitglieder zu erklären und vorherzusagen (vgl. Lewis, S. XII).
Covid-19 und die Maßnahmen zu Eindämmung der Pandemie wirkten für viele Menschen lebensverändernd und zwangen Unternehmen zu teilweise substantiellen Anpassungen ihrer gewohnten Praktiken. Sie führten jedoch auch zu Veränderungen, die sich weitgehend außerhalb der öffentlichen Wahrnehmung vollzogen haben. Ein Beispiel hierfür ist die deutliche Verschiebung der Kraftverhältnisse im Markt für Bannerwerbung, auf dem sich sowohl für Werbetreibende, als auch für Vermarkter zu deutlichen Veränderungen kam. Gleichzeitig verändert sich der Markt strukturell. Es kommt derzeit zu einer Professionalisierung, bei der Werbetreibende heute die richtigen Weichen stellen müssen, um in Zukunft zu den Gewinnern in diesem Markt zu zählen. Dieser Report fasst die wichtigen strukturellen und Corona-bedingten Veränderungen zusammen und erklärt die Implikationen für Werbetreibende.
The seamless fusion of the virtual world of information with the real physical world of things is considered the key for mastering the increasing complexity of production networks in the context of Industry 4.0. This fusion, widely referred to as the Internet of Things (IoT), is primarily enabled through the use of automatic identification (Auto-ID) technologies as an interface between the two worlds. Existing Auto-ID technologies almost exclusively rely on artificial features or identifiers that are attached to an object for the sole purpose of identification. In fact, using artificial features for the purpose of identification causes additional efforts and is not even always applicable. This paper, therefore, follows an approach of using multiple natural object features defined by the technical product information from computer-aided design (CAD) models for direct identification. By extending optical instance-level 3D-Object recognition by means of additional non-optical sensors, a multi-sensor automatic identification system (AIS) is realised, capable of identifying unpackaged piece goods without the need for artificial identifiers. While the implementation of a prototype confirms the feasibility of the approach, first experiments show improved accuracy and distinctiveness in identification compared to optical instance-level 3D-Object recognition. This paper aims to introduce the concept of multisensor identification and to present the prototype multi-sensor AIS.
Classification model of supply chain events regarding their transferability to blockchain technology
(2021)
The blockchain technology represents a decentralized database that stores information securely in immutable data blocks. Regarding supply chain management, these characteristics offer potentials in increasing supply chain transparency, visibility, automation, and efficiency. In this context, first token-based mapping approaches exist to transfer certain supply chain events to the blockchain, such as the creation or assembly of parts as well as their transfer of ownership. However, the decentralized and immutable structure of blockchain technology also creates challenges. In particular, the scalability, storage capacity, and the special requirements for storage formats make it currently impossible to map all supply chain events unrestrictedly on the blockchain. As a first step, this paper identifies important supply chain events for different use cases combining blockchain technology and supply chain management. Secondly, the supply chain events are classified in terms of their expected technical properties and their relevance for the respective use case. Finally, the identified supply chain events are evaluated regarding their transferability to blockchain technology and a classification model is introduced.
Das Weltwirtschaftswachstum der vergangenen Jahrzehnte war durch die Dynamik der Digitalisierung und Globalisierung in den Lieferketten geprägt. Die Corona-Pandemie hat die Abhängigkeit und Verletzlichkeit der Lieferketten offengelegt. Trotz einer Vielzahl verbindlicher Standards haben Unternehmen die Digitalisierung und Arbeitsteilung auch für regulatorische Arbitrage genutzt. Einerseits erhöht das die Effizienz der Wirtschaft - was mithin ökologische Ressourcen schont - andererseits werden damit internationale Standards konterkariert. Globalisierung und Digitalisierung sind Segen und Fluch zugleich.
In this paper, we examine the political gridlock in reforming the Economic and Monetary Union. We utilize a two–stage game with imperfect information in order to study the optimal sequencing. The main results are: first, optimal sequencing requires for incompliant Member States a default option in stage–two, which in principle is related to the today's fiscal architecture (EMU-I). Second, we show that compliant countries prefer a reform equilibrium today if and only if they have a free choice about the preferred fiscal architecture at the end — either EMU-II with binding European coordination or EMU-I related to Maastricht. Noteworthy, our sequencing approach works for any design of the EMU-II architecture.
Das aufsehenerregende Urteil des Bundesverfassungsgerichts in Sachen Staatsanleiheankäufe der Europäischen Zentralbank verlangt eine ökonomische und verfassungsrechtliche Gesamtschau. Vor allem im interdisziplinären Kontext erschließt sich die herausfordernde Abgrenzung der supranationalen Währungspolitik von der nationalen Wirtschaftspolitik. Der im Urteil neuentwickelte Standpunkt ist in der wissenschaftlichen Literatur unterschätzt, obzwar tradierte und neue rechtspolitische Grundsätze für die zukünftige Ausformung der Europäischen Wirtschafts- und Währungsunion subsumiert werden.
Die leistungsfähigen Verfahren des maschinellen Lernens halten unaufhaltsam Einzug in die verschiedensten Anwendungsbereiche im Finanzsektor. Während sie von einer großen Gemeinschaft von Forschern und Anwendern laufend weiterentwickelt werden, nimmt sich auch die Bankenaufsicht dieses Themas aktiv an und bezieht in Richtlinien und Diskussionspapieren Stellung.
Dieser Beitrag entwickelt ein Managementmodell, das Unternehmen dabei unterstützt, relevante Aktionsfelder zur nachhaltigen Steuerung von Konsumenten entlang der eigenen Customer Journey zu identifizieren. Aufbauend auf dem SHIFT-Modell, als strukturelle Abbildung des nachhaltigen Käuferverhaltens, wird die Customer Journey entlang der owned, paid und earned Touchpoints aufgezogen. Mithilfe des faktisch analytischen Ansatzes, der die Integration neuer Erkenntnisse in die Forschungsstrategie unterstützt, werden Aktionsfelder identifiziert, die als grundlegende Logik Unternehmen dazu anleiten sollen, bei der Ausgestaltung der eigenen nachhaltigen Customer Journey dieses Strukturraster anzunehmen.
Distributed ledger technologies such as the blockchain technology offer an innovative solution to increase visibility and security to reduce supply chain risks. This paper proposes a solution to increase the transparency and auditability of manufactured products in collaborative networks by adopting smart contract-based virtual identities. Compared with existing approaches, this extended smart contract-based solution offers manufacturing networks the possibility of involving privacy, content updating, and portability approaches to smart contracts. As a result, the solution is suitable for the dynamic administration of complex supply chains.
Ambitious goals set by the European Union strategy towards the emission reduction of multimodal logistic chains and new requirements for intermodal terminals set by the evolution of customer needs, contribute to a shift in the driver for the infrastructure development: from economy of scale to economy of density. This paper aims to present an innovative method for designing a process oriented technology chain for intermodal terminals in order to fulfill these new demanding requirements. The results of the case study of the Zero Emission Logistic Terminal Reutlingen are presented, highlighting how this particular context enables the design and development of a modular concept, paving the way for the generalization of the findings towards the transfer to similar contexts of other European cities.
Sustainability is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Business Model is a plan for the successful operation of a business, identifying sources of revenue, the intended customer base, products, and details of financing.
Circular economy is an approach of how a company creates, captures and delivers value, with a value creation logic designed to improve resource efficiency through contributing to extending the useful life of products and parts (e.g., through long-life design, repair and remanufacturing) and closing material loops.
Stetiger Wandel macht auch vor dem Vertriebsprozess deutscher KMU nicht Halt. Evolutive Umwelteinflüsse sowie revolutionäres Handeln stehen im Zentrum eines Umbruchs im Vertrieb.

Für die digitale 3D-VR-Fabrikplanung sind unterschiedliche Soft- und Hardwaresysteme am Markt verfügbar, die teilweise erhebliche Kompatibilitätsprobleme aufweisen. Für die Bewertung der Hardwareeignung für die 3D-VR-Fabrikplanung wird ein Bewertungssystem vorgestellt, das anhand konkreter Softwareapplikationen und einem passiven 3D-Stereo-Monitor mit Head-Tracking erläutert wird. Es wird dazu auch die Notwendigkeit des Einsatzes von Software-Middleware zur Nutzungssteigerung diskutiert.
Conventional production systems are evolving through cyber-physical systems and application-oriented approaches of AI, more and more into "smart" production systems, which are characterized among other things by a high level of communication and integration of the individual components. The exchange of information between the systems is usually only oriented towards the data content, where semantics is usually only implicitly considered. The adaptability required by external and internal influences requires the integration of new or the redesign of existing components. Through an open application-oriented ontology the information and communication exchange are extended by explicit semantic information. This enables a better integration of new and an easier reconfiguration of existing components. The developed ontology, the derived application and use of the semantic information will be evaluated by means of a practical use case.
Trotz Niedrigzinsphase bleibt das Working Capital Management ein wichtiger Treiber für Wertgrößen in Unternehmen und wichtiges Managementinstrument. Unsere Ergebnisse über 115 Unternehmen aus den wichtigsten deutschen Indizes in den Jahren 2011 bis 2017 zeigen, dass effektives Working Capital Management einen positiven Einfluss auf die Rentabilität und den Unternehmenswert haben kann. Gleichzeitig zeigen unsere Ergebnisse aber auch, dass dem Working Capital Management jüngst weniger Aufmerksamkeit zuteilgeworden ist und digitale Innovationen vermutlich noch nicht in dem Umfang zur Effizienzsteigerung eingesetzt werden, wie dies möglich erscheint. Selbst vor dem Hintergrund andauernd niedriger Kapitalmarktzinsen ist dies kritisch zu sehen.
Imagine a world in which the search for tomorrow's trends is not subject to a long and laborious data search but is possible with a single mouse click. Through the use of artificial intelligence (AI), this reality is made possible and is to be further advanced through research. The study therefore aims to provide an initial overview of the young research field. Based on research, expert interviews, company and student surveys, current application possibilities of AI in the innovation process (defined as Smart Innovation), existing challenges that slow down the further development are discussed in more detail and future application possibilities are presented. Finally, a recommendation for action is made for business, politics and science to help overcome the current obstacles together and thus drive the future of Smart Innovation.
Sichtprüfungen von Produktoberflächen werden überwiegend von Mitarbeitern ausgeführt, wobei Automatisierungsansätze mit Kamera- und Bildverarbeitungssystemen großes Potenzial zeigen. Auch Cobots werden in Qualitätssicherungsprozesse einbezogen.Im Folgenden werden die Integrationsmöglichkeiten von Cobots in die Sichtprüfung diskutiert und ein Entscheidungsmodell dargestellt, mit dem Sichtprüfungsprozesse auf ihre Cobot-Tauglichkeit überprüft werden können. Das Entscheidungsmodell ist für die direkte Integration in bereits existierende Cobot-Eignungsuntersuchungsverfahren konzipiert und dient als erste strategische Entscheidungshilfe.

As consumer awareness surrounding impacts of the climate crisis continues to be a notable threat, businesses are searching for new models to make their sustainability profile even better. As a result, the implementation of a company’s sustainability vision following the SDGs has to be linked closely to the integration of customers into strategic action. One success factor is the management of customers over their entire life cycle. The Customer Journey serves as a model to systematise this approach, by designing touchpoints throughout the purchasing process in order to motivate consumers to act sustainably. Based on behaviour models, the authors develop recommendations for the food industry to design a sustainable Customer Journey that helps to reduce the percentage of consumers reporting positive attitudes to sustainable products while not exhibiting corresponding behaviour.
Forecasting demand is challenging. Various products exhibit different demand patterns. While demand may be constant and regular for one product, it may be sporadic for another, as well as when demand occurs, it may fluctuate significantly. Forecasting errors are costly and result in obsolete inventory or unsatisfied demand. Methods from statistics, machine learning, and deep learning have been used to predict such demand patterns. Nevertheless, it is not clear for what demand pattern, which algorithm would achieve the best forecast. Therefore, even today a large number of models are used to forecast on a test period. The model with the best result on the test period is used for the actual forecast. This approach is computationally and time intensive and, in most cases, uneconomical. In our paper we show the possibility to use a machine learning classification algorithm, which predicts the best possible model based on the characteristics of a time series. The approach was developed and evaluated on a dataset from a B2B-technical-retailer. The machine learning classification algorithm achieves a mean ROC-AUC of 89%, which emphasizes the skill of the model.
Prior to the introduction of AI-based forecast models in the procurement department of an industrial retail company, we assessed the digital skills of the procurement employees and surveyed their attitudes toward a new digital technology. The aim of the survey was to ascertain important contextual factors which are likely to influence the acceptance and the successful use of the new forecast tool. What we find is that the digital skills of the employees show an intermediate level and that their attitudes toward key aspects of new digital technologies are largely positive. Thus, the conditions for high acceptance and the successful use of the models are good, as evidenced by the high intention of the procurement staff to use the models. In line with previous research, we find that the perceived usefulness of a new technology and the perceived ease of use are significant drivers of the willingness to use the new forecast tool.
Forecasting demand is challenging. Various products exhibit different demand patterns. While demand may be constant and regular for one product, it may be sporadic for another, as well as when demand occurs, it may fluctuate significantly. Forecasting errors are costly and result in obsolete inventory or unsatisfied demand. Methods from statistics, machine learning, and deep learning have been used to predict such demand patterns. Nevertheless, it is not clear for what demand pattern, which algorithm would achieve the best forecast. Therefore, even today a large number of models are used to forecast on a test period. The model with the best result on the test period is used for the actual forecast. This approach is computationally and time intensive and, in most cases, uneconomical. In our paper we show the possibility to use a machine learning classification algorithm, which predicts the best possible model based on the characteristics of a time series. The approach was developed and evaluated on a dataset from a B2B-technical-retailer. The machine learning classification algorithm achieves a mean ROC-AUC of 89%, which emphasizes the skill of the model.
COVID-19 and educational inequality: How school closures affect low- and high-achieving students
(2021)
In spring 2020, governments around the globe shut down schools to mitigate the spread of the novel coronavirus. We argue that low-achieving students may be particularly affected by the lack of educator support during school closures. We collect detailed time-use information on students before and during the school closures in a survey of 1099 parents in Germany. We find that while students on average reduced their daily learning time of 7.4 h by about half, the reduction was significantly larger for low-achievers (4.1 h) than for high-achievers (3.7 h). Low-achievers disproportionately replaced learning time with detrimental activities such as TV or computer games rather than with activities more conducive to child development. The learning gap was not compensated by parents or schools who provided less support for low-achieving students.
We analyze economics PhDs’ collaborations in peer-reviewed journals from 1990 to 2014 and investigate such collaborations’ quality in relation to each co-author’s research quality, field and specialization. We find that a greater overlap between co-authors’ previous research fields is significantly related to a greater publication success of co-authors’ joint work and this is robust to alternative specifications. Co-authors that engage in a distant collaboration are significantly more likely to have a large research overlap, but this significance is lost when co-authors’ social networks are accounted for. High quality collaboration is more likely to emerge as a result of an interaction between specialists and generalists with overlapping fields of expertise. Regarding interactions across subfields of economics (interdisciplinarity), it is more likely conducted by co- authors who already have interdisciplinary portfolios, than by co-authors who are specialized or starred in different subfields.
Academic research is vital for innovation and industrial growth. However, a potential burden of processing ever more knowledge could be affecting research output and researchers’ careers. We look at a dataset of researchers who have published in journals in the field of economics during a period of 45 years. For a subset of these researchers, we amass data from journals listed in the EconLit database, supplemented with years of birth from public sources. Our results show an increase in the age of researchers at their first publication, in the number of articles referenced in debut articles, and in the number of co-authors. Simultaneously, we observe a decline in the probability of researchers changing research fields. Our findings extend earlier findings on patents and hint at a burden of knowledge pervading different areas of human progress. Moreover, our results indicate that researchers develop strategies of specialisation to deal with this challenge.
Omnichannel retailing and sustainability are two important challenges for the fast fashion industry. However, the sustainable behavior of fast fashion consumers in an omnichannel environment has not received much attention from researchers. This paper aims to examine the factors that determine consumers’ willingness to participate in fast fashion brands’ used clothes recycling plans in an omnichannel retail environment. In particular, we examine the impact of individual consumer characteristics (environmental attitudes, consumer satisfaction), organizational arrangements constitutive for omnichannel retailing (channel integration), and their interplay (brand identification, impulsive consumption). A conceptual model was developed based on findings from previous research and tested on data that were collected online from Chinese fast fashion consumers. Findings suggest that consumers’ intentions for clothes recycling are mainly determined by individual factors, such as environmental attitudes and consumer satisfaction. Organizational arrangements (perceived channel integration) showed smaller effects. This study contributes to the literature on omnichannel (clothing) retail, as well as on sustainability in the clothing industry, by elucidating individual and organizational determinants of consumers’ recycling intentions for used clothes in an omnichannel environment. It helps retailers to organize used clothes recycling plans in an omnichannel environment and to motivate consumers to participate in them.
Today, many industrial tasks are not automated and still require human intervention. One of these tasks is the unloading of oversea containers. After the end of transportation to the sorting center, the containers must be unloaded manually for further sending the parcels to the recipients. A robot-based automatic unloading of containers was therefore researched. However, the promising results of the system developed in these projects could not be commercialized due to problems with its reliability. Mechanical, algorithmic or other limitations are possible causes of the observed errors. To analyze errors, it is necessary to evaluate the results of the robot’s work without complicating the existing system by adding new sensors to it. This paper presents a reference system based on machine learning to evaluate the robotics grasps of parcels. It analyzes two states of the container: before and after picking up one box. The states are represented as a point cloud received from a laser scanner. The proposed system evaluates the success of transferring a box from an overseas container to the sorting line by supervised learning using convolutional neural networks (CNN) and manual labeling of the data. The process of obtaining a working model using a hyperband model search with a maximum classification error of 3.9 % is also described.
Teaching at assembly workstations in production in SMEs (small and medium sized companies) often does not take place at all or only insufficiently. In addition to the lack of technical content, there are also aggravatingly incorrect movement sequences from an ergonomic point of view, which "untrained" people usually automatically acquire. An AI based approach is used to analyze a definite workflow for a specific assembly scope regarding the behavior of several employees. Based on these different behaviors, the AI gives feedback at which points in time, work steps and movement’s particularly dangerous incorrect postures occur. Motion capturing and digital human model simulation in combination with the results of the AI define the optimized workflow. Individual employees can be trained directly due to the fact that AI identifies their most serious incorrect postures and provide them with a direct analogy of their “wrong” posture and “easy on the joints posture”. With the assistance of various test persons, the AI can conduct a study in which the most frequently occurring incorrect postures can be identified. This could be realized in general or tailored to specific groups of people (e.g. "People over 1.90m tall must be particularly careful not to make the following mistake...). The approach will be tested and validated at the Werk150, the factory of the ESB Business School, on the campus of the Reutlingen University. The new gained knowledge will be used subsequently for training in SMEs.
Many scientific reports have warned about the catastrophic consequences of unchecked climate change, with the latest international report calling for emissions of climate pollutants to reach net zero by around 2050 (IPCC, 2018). Limiting warming to 1.5°C could save more than 100 million people from water shortages, as many as 2 billion people from dangerous heatwaves, and the majority of species from climate change extinction risks (IPCC, 2018; Warren et al., 2018). The actions taken to achieve these climate outcomes would generate benefits of more than $20 trillion while easing global economic inequality (Burke et al., 2018). Scientists make it clear that it is physically possible to meet these goals using today’s technologies (Holz et al., 2018). Yet emissions of climate pollutants continue to grow, reaching a new record high in 2018 (Jackson et al., 2018). Clearly, scientific evidence has failed to spark needed climate action. The question now is: what can?
Coopetitive endeavors offer valuable strategic options for firms. Yet, many of them are failure-prone as partners must balance collective and private interest. While interpartner trust is considered central for alliance success, paradoxically, the role and dynamics of trust is still not understood. We synthesize a computational model, capturing relational dynamics of an alliance, encompassing coevolution of trust, partner contributions, and (relative) alliance interactions. Analyzing alliance dynamics using simulation we find and explore a tipping boundary, separating a regime of alliance failure and success. We identify implications for collaborative (aspirations) and private strategies (openness). Our analyses reveal that strategies informed by a static mental model of partner trust, contributions, and openness tend to yield subpar alliance results and hidden failure-risk. We discuss implications for management theory.
The maintenance of railway infrastructure remains a challenge. Data acquisition technologies have evolved because of Industry 4.0, expanding the capabilities of predictive maintenance. Despite the advances, the potential of these emerging technologies has not been fully realised. This paper presents a technology selection framework in support of railway infrastructure predictive maintenance, which is based on qualitative methods. It consists of three stages, including the mapping of the infrastructure characteristics with the identified technologies, the evaluation of the most appropriate technologies, and the sourcing thereof. This presents the collective decision support output of the framework.
The technologies of digital transformation, such as the Internet-of-Things (IoT), artificial intelligence or predictive maintenance enable significant efficiency gains in industry and are becoming increasingly important as a competitive factor. However, their successful implementation and creative, future application requires the broad acceptance and knowledge of non-IT-related groups, such as production management students, engineers or skilled workers, which is still lacking today. This paper presents a low-threshold training concept bringing IoT-technologies and applications into manufacturing related higher education and employee training. The concept addresses the relevant topics starting from IoT-basics to predictive maintenance using mobile low-cost hardware and infrastructure.
Maintenance is an increasingly complex and knowledge-intensive field. In order to address these challenges, assistance systems based on augmented, mixed, or virtual reality can be applied. Therefore, the objective of this paper is to present a framework that can be used to identify, select, and implement an assistance system based on reality technology in the maintenance environment. The development of the framework is based on a systematic literature review and subject matter expert interviews. The framework provides the best technological and economic solution in several steps. The validation of the framework is carried out through a case study.
Railway operators are being challenged by increasing complexity and safeguarding the availability of passenger rolling stock, bringing maintenance and especially emerging technologies into the focus. This paper presents a model for selection and implementation of Industry 4.0 technologies in rolling stock maintenance. The model consists of different stages and considers the main components of rolling stock, the related appropriate maintenance strategies and Industry 4.0 technologies considering the maturity level of the railway operators. Relevant criteria and main prerequisites of the technologies were identified. The model proposes relevant activities and was validated by industry experts.
Increasing complexity in manufacturing processes poses new challenges for industrial maintenance. In addition, advanced machine monitoring and lifetime forecasting options expand the tools and maintenance strategies available. Today, maintenance strategy selection is performed sequentially usually based on prioritised machines and components. These selections are optimized locally for each machine isolated, not considering the context of other machines within the value-adding network. To overcome these challenges, this paper presents an approach for an integrated maintenance strategy selection in one-step by an integrated model considering possible machine failures and the context of other machines within the value-adding network in parallel.
This paper presents the concept of the system architecture of a flexible cyber-physical factory control system. The system allows the automation of process structures using cyber-physical fractal nodes. These nodes have a functional and independent form and can be clustered to larger structures. This makes it possible to equip the factory with a flexible, freely scalable, modular system. The description of this system architecture and the associated rules and conditions is outlined in the concept.
Die Digitalisierung und Nachhaltigkeit werden die Erwartungen und Anforderungen an die Controller dauerhaft und umfassend verändern. Die Lehre hat für den Rollenwandel eine hohe Relevanz. Eine auf die veränderten Anforderungen abgestimmte Ausbildung bietet den Unternehmen die Möglichkeit, Controller mit diesen veränderte Rollenprofilen für ihre Organisation zu gewinnen. Für die Absolventen mit dem Berufswunsch Controlling sichert das veränderte Rollenprofil ihre langfristige Arbeitsmarktfähigkeit. Für den Rollenwandel selbst kann diese als Treiber verstanden werden.
Trotz der Bedeutung der Lehre für den Rollenwandel gibt es dazu bislang wenige Forschungsergebnisse zur konkreten Abbildung der Rollen in der Lehre. Es stellt sich daher die Frage, wie Hochschulen in ihren Studiengängen die Rollen grundsätzlich abbilden und mit welcher Intensität sowie Kombinationen die Rollen gelehrt werden. Diese Forschungsfrage wird anhand einer Analyse von controllingspezifischen Masterstudiengängen und deren Modulhandbücher evaluiert und diskutiert.
Im Ergebnis stellt sich der Rollenwandel in der Controllinglehre sehr heterogen dar. Es dominiert die Vermittlung der klassische Controllerrolle gefolgt von der Business Partner Rolle. Lehrinhalte bezogen auf die Rollen des digitalen Controllers oder Risikocontrollers sind schwach ausgeprägt. Für die Übernahme einer Controllerrolle im Nachhaltigkeitsmanagement existiert kaum ein Lehrangebot. Diese Ergebnisse sollen zum Diskurs über den Rollenwandel und die Gestaltung der Lehre im Controlling beitragen.
Stellenausschreibungen sind ein wichtiges Mittel, um Rollen von Controllern auf dem Arbeitsmarkt zu kommunizieren. Stellenanzeigen öffnen ein Fenster zu dem, was Firmen als Rollen für ihre Controller wahrnehmen. Welche Rollen Stellenanzeigen kommunizieren, ist bisher nicht bekannt. Unter Verwendung einer großen Stichprobe von 889 Stellenanzeigen und eines Text-Mining-Ansatzes zeigen wir, dass es offenbar eine Mischung verschiedener Rollentypen mit einem starken Fokus auf einen eher klassischen Rollentyp gibt, die Watchdog-Rolle. Personen mit Business-Partner-Eigenschaften werden dagegen häufiger für Führungspositionen oder in Familienunternehmen und kleinen und mittleren Unternehmen (KMU) gesucht. Die Ergebnisse stellen die derzeitige Rollen-diskussion für Controller als Business Partner in der Praxis und in einigen Bereichen der Wissenschaft in Frage.
Veränderungen der Rolle von Controllern in Großkonzernen - Ergebnisse einer empirischen Erhebung
(2021)
Die anhaltende Diskussion über die Rolle von Management Accountants (MA) führt häufig dazu, dass die Rolle des Business Partners (BP) als die Rolle der Wahl angesehen wird. Dennoch scheinen viele Wissenschaftler und Praktiker davon auszugehen, dass diese Rolle den Managern und MA klar ist, dass sie für sie sinnvoll ist und alle Manager und MA ihr zustimmen und sie umsetzen. Unstimmigkeiten zwischen der tatsächlichen Rolle, der wahrgenommenen und der erwarteten Rolle könnten zu Identitäts- und Rollenkonflikten führen. Dieser Beitrag basiert auf einer quantitativen empirischen Studie in einem großen deutschen High-Tech-Unternehmen im Jahr 2019, dessen Top-Management sich für die Einführung der BP-Rolle entschied.
F&E-Bereiche nur kostenorientiert zu steuern, wird der immensen Bedeutung von Innovationserfolgen für die Zukunft von Unternehmen nicht gerecht. Ein agiles Innovationsmanagement benötigt ein solides F&E-Performance-Managementsystem als Basis. Entscheidend ist neben der Wahl "richtiger" Methoden und Kennzahlen die Wahrnehmung der Business-Partnerrolle durch die Controller. In diesem Beitrag wird das Innovation Performance Management beispielhaft für WMF konkretisiert.
