In recent years, machine learning algorithms have made a huge development in performance and applicability in industry and especially maintenance. Their application enables predictive maintenance and thus offers efficiency increases. However, a successful implementation of such solutions still requires high effort in data preparation to obtain the right information, interdisciplinarity in teams as well as a good communication to employees. Here, small and medium sized enterprises (SME) often lack in experience, competence and capacity. This paper presents a systematic and practice-oriented method for an implementation of machine learning solutions for predictive maintenance in SME, which has already been validated.
Lean Management hat in viele Unternehmen Einzug gehalten. Lean Konzepte stellen neue Anforderungen an die Art und Struktur der benötigten Kosteninformation, welche von traditionallen Kostenrechnungssystemen nicht unmittelbar erfüllt werden. Vertreter eines „Lean Accounting“ schlagen deshalb teils radikale Änderungen und eine Vereinfachung der Kostenrechnung vor. Der Beitrag diskutiert die Beschränkungen der traditionellen Kostenrechnung bei der Umsetzung von Lean Management und stellt ausgewählte Ansätze eines „Accounting for Lean“ vor. Die Analyse zeigt, dass Ansätze des Lean Accounting zu eng fokussiert sind und die in der Praxis vorhandene Pluralität der Kostenrechnungsfunktionen nicht adäquat abbilden können. Eine radikale Neugestaltung bestehender Kostenrechnungssysteme wird deshalb als unrealistisch und unbegründet verworfen. Der Beitrag entwickelt alternative Vorschläge, wie Konzepte des Lean Managements und die dafür benötigte Kosteninformation in traditionellen Kostenrechnungssystemen integriert werden können.
Unternehmen, die restriktiv keinerlei Adaptionen innerhalb der Strukturen vornehmen, können angesichts der verschärften Wettbewerbssituation im tagtäglichen Business nicht bestehen. Warum Agilität ein geeignetes Tool für die Umsetzung einer innovativen Anpassung beschreibt und in zukunftsorientierten Unternehmen als Katalysator agiert, soll in diesem Artikel näher erläutert werden.
Die Idee des Ambush Marketing ist es, von den Erfolgen des Sponsoring zu profitieren, ohne die Pflichten eines offiziellen Sponsors einzugehen. Ambusher besitzen keine Vermarktungsrechte an einer Veranstaltung, bauen aber dennoch durch ihre Marketingmaßnahmen eine Verbindung zu einem Event auf. Der Grat zwischen der Verletzung von Sponsorenrechten und kreativ-innovativer Kommunikationspolitik ist dabei oft sehr schmal, weswegen Ambush Marketing kontrovers diskutiert wird.
Bei großen Sportereignissen geht es für Verbände und Sponsoren um Millionen, entsprechend scharf verteidigen sie ihre Marketingrechte. Verschiedene Unternehmen zeigen, wie sich dieses "Monopol" kreativ umgehen lässt. Im vorliegenden Beitrag werden die Grundlagen des Ambush Markting präsentiert und exemplarisch Ambush Aktivitäten von Kulula, Bruno Banani und Burger King vorgestellt, die gezielt Ambush Marketing einsetzten, um im Wettstreit mit ihren Konkurrenten und gegen offizielle Sponsoren Punkte zu sammeln.
The supply of customer-specific products is leading to the increasing technical complexity of machines and plants in the manufacturing process. In order to ensure the availability of the machines and plants, maintenance is considered as an essential key. The application of cyber-physical systems enables the complexity to be mastered by improving the availability of information, implementing predictive maintenance strategies and the provision of all relevant information in real-time. The present research project deals with the development of a cost-effective and retrofittable smart maintenance system for the application of ultraviolet (UV) lamps. UV lamps are used in a variety of applications such as curing of materials and water disinfection, where UV lamps are still used instead of UV LED due to their higher effectiveness. The smart maintenance system enables continuous condition monitoring of the UV lamp through the integration of sensors. The data obtained are compared with data from existing lifetime models of UV lamps to provide information about the remaining useful lifetime of the UV lamp. This ensures needs-based maintenance measures and more efficient use of UV lamps. Furthermore, it is important to have accurate information on the remaining useful lifetime of a UV lamp, as the unplanned breakdown of a UV lamp can have far-reaching consequences. The key element is the functional model of the envisioned cyber-physical system, describing the dependencies between the sensors and actuator, the condition monitoring system as well as the IoT platform. Based on the requirements developed and the functional model, the necessary hardware and software are selected. Finally, the system is developed and retrofitted to a simulated curing process of a 3D printer to validate its functional capability. The developed system leads to improved information availability of the condition of UV lamps, predictive maintenance measures and context-related provision of information.
Airports largely outgrew their sole purpose of simply being travel hubs and by connecting millions of passengers to their destinations each year on an international scale, they have become increasingly interesting for business and related marketing opportunities. In fact, passengers are easily segmented and can be reached effectively throughout specific airport areas, making some areas more suitable for advertising than others. Emotional states, roaming time and the freedom to move vastly, influence how much information passengers are able to absorb from their direct surroundings. Finally our research shows that some areas are more suitable than others. Therefore a careful selection of airport locations for communication will be key to secure the impact and improve the effectiveness of communication measures. With these insights, advertisers can deliberately choose the areas that are most effective for displaying their ads.
The promise of the EVs is twofold. First, rejuvenating a transport sector that still heavily depends on fossil fuels and second, integrating intermittent renewable energies into the power mix. However, it is still not clear how electricity networks will cope with the predicted increase in EVs and their charging demand, especially in combination with conventional energy demand. This paper proposes a methodology which allows to predict the impact of EV charging behavior on the electricity grid. Moreover, this model simulates the driving and charging behavior of heterogeneous EV drivers which differ in their mobility pattern, decision-making heuristics and charging strategies. The simulations show that uncoordinated charging results in charging load clustering. In contrast, decentralized coordination allows to fill the valleys of the conventional load curve and to integrate EVs without the need of a costly expansion of the electricity grid.
This article adopts a qualitative comparative causal mapping approach to extend knowledge of the interrelated barriers to public entrepreneurship and the outcomes of such entrepreneurship. The results highlight marked differences between the sales segment and the distribution grid segment of German public enterprises that should prompt a refined perspective on public entrepreneurship. Notably, besides intra-organizational barriers and those interfering from the external environment, results also show that a public enterprise’s supervisory board can hinder its progress. This study thus contributes to recent discussion on governance and entrepreneurship by revealing a feature that could distinguish public from private enterprises.
To remain relevant and mitigate disruption, traditional companies have to engage in multiple fast-paced experiments in digital offerings: revenue-generating solutions that leverage digital technologies to address customer needs. After launching several digital offering initiatives, reinsurance giant Munich Re noticed that many experienced similar challenges. This briefing describes how Munich Re addressed these common challenges by building a foundation for experimenting more systematically and successfully with digital offerings. The foundation has enabled Munich Re to become a serial innovator of digital offerings.
Als Google vor einigen Jahren begann, seine riesigen Personaldatenbestände auszuwerten, um herauszufinden, welche Eigenschaften gute Führungskräfte ausmachen, betrat es Neuland. Die Ergebnisse legten nahe, die Daten auch für andere personalwirtschaftliche Fragen zu nutzen (vgl. Garvin).
Inzwischen beschäftigen sich nicht nur Technologie-unternehmen wie Google mit Verfahren, die unter dem Schlagwort People Analytics (auch HR Analytics oder Workforce Analytics) intensiv diskutiert und erforscht werden. Dabei werden die umfangreichen Bestände an mitarbeiterbezogenen Daten, die bei der Rekrutierung, bei Mitarbeiterumfragen oder Leistungsbeurteilungen anfallen, systematisch analysiert und für Prognosen genutzt (vgl. Marler/Boudreau, S. 15). Dem liegt die Annahme zugrunde, dass Personalentscheidungen verbessert werden, wenn sie nicht nur auf Intuition und Erfahrung beruhen, sondern zudem auf einem soliden Datenfundament.
