Offshore-Windenergieanlagen gewinnen in Zeiten der Energiewende als leistungsfähige und verlässliche Energiequelle zunehmend an Bedeutung. Um jedoch langfristig eine zentrale Rolle in der Energiewende einnehmen zu können, ist es wichtig, dass sie auch wirtschaftlich profitabel sind. Verglichen mit anderen Energiequellen sind Offshore-Windenergieanlagen noch mit relativ hohen Kosten verbunden. Besonders die Instandhaltung der Anlagen ist, vor allem aufgrund der Lage, aufwendig und kostenintensiv. Hinzu kommt, dass die Disposition der Instandhaltungsaufgaben bisher händisch erledigt werden musste, da es keine passende Software für die Disposition in diesem Anwendungsbereich gab.
[Projekt: INGEMO] Bewertung des Transformationsaufwands verschiedener Geschäftsmodellalternativen
(2018)
Das Projekt INGEMO dient der Entwicklung und Erprobung einer integrierten Methodik zur Geschäftsmodellinnovation und -implementierung in der Green Economy. Am Anfang der Entwicklung dieser Methodik steht die Bewertung verschiedener Alternativen eines zukünftigen Geschäftsmodells. In der Bewertung spielen neben der strategischen Relevanz der einzelnen Alternativen auch der mit der Umsetzung verknüpfte Transformationsaufwand und die Veränderungsfähigkeit des Unternehmens eine wesentliche Rolle. Im folgenden Beitrag wird daher ein Tool vorgestellt, das bei der Bewertung des Transformationsaufwands
verschiedener Geschäftsmodelle in Abhängigkeit der eigenen Veränderungsfähigkeit unterstützt.
The FIR at the RWTH Aachen University continuously develops the concept and the principles of RoM further. It is already noticeable that the gap between companies that began preparing their maintenance departments for Industrie 4.0 years ago and those that are still struggling with the mere foundations of a professional maintenance organisation is rapidly increasing.
The first driver of the development sparked by Industrie 4.0 is the collection of and work with condition data. It is used to create a digital shadow of a service, e.g. maintenance measures in a specific
context. In the future, critical machine functions will be monitored continuously within production processes.
Based on these observations, the likelihood of machine failures can be predicted, which makes it possible to prioritize data-based maintenance measures. This means that maintenance activities, i.e. production plans, are based on prognoses regarding machine failures. By doing so, the currently existing separation between inspection, maintenance and reactive measures can be overcome, resulting in a holistic approach to maintenance. Maintenance specialists receive support from assistance systems, which give them access to all relevant information (e.g. machine history, spare part availability, proposals for measures, etc.). As a result, they can take on routine tasks in different areas as well and contribute to the increased flexibility of the production process. Although data is becoming an increasingly important driver of successful maintenance strategies,
maintenance employees continue to be central to specific tasks, machines and systems. In the future, it can be expected that they choose to become experts in a certain field and, ideally, actively share their knowledge with others within an open maintenance culture. Systems for interdisciplinary collaboration will be made part of everyday practice.
The maintenance department will be a center and distributor of knowledge in the agile company of the future.Only through the interaction of the outlined success principles, which amount to a paradigm shift within the maintenance department, the potential
benefit of maintenance as defined by RoM can be fully exploited, creating a long-term competitive advantage for those who consistently follow the path towards Industrie 4.0 in maintenance.
Factory automation and production are currently
undergoing massive changes, and 5G is considered being a key
enabler. In this paper, we state uses cases for using 5G in the
factory of the future, which are motivated by actual needs of the
industry partners of the “5Gang” consortium. Based on these use
cases and the ones by 3GPP, a 5G system architecture for the
factory of the future is proposed. It is set in relation to existing
architectural frameworks.
Many ERP systems support configurable materials. Due to an ever increasing number of product variants the benefits of this approach are well understood. However, these implementations are not standardized. In this article we propose a new standard interface for the exchange of configuration data. This would lead to further benefits as systems as Advanced Planning systems could better use manufacturing flexibility while web shops as Amazon could easily integrate manufacturers of complex products with much reduced implementation effort.
Effects of synergy and economies of scale in the repair network constitute a major share for improvements in operational efficiency in aircraft repair and overhaul market. However, the process of transferring work among repair shops is associated with high costs, risks of delays and quality losses, which directly affect customer satisfaction and can lead to considerable losses of market share and revenue.
While the process of transferring work itself is well understood, risk management is not following a systematic approach today at Airbus because there is no specific guideline for transfer of work process in repair and the company did not run many projects related with work transfer on repair side in the past. Therefore, in the frame of cost optimization project, closure of existing repair shops and creating a centralized European repair shop will affect supply chain and repair performance during or after the work transfer process. Major risk factors and key aspects of the process are repair performance, quality, turnaround time, tooling & jigs, supplier & procurement etc. Furthermore, the implementation of collaborative repair networks that perform work during transition phase and support the consolidated repair station is essential.
This study mainly focuses on transfer of repair activities from Airbus Getafe to Airbus Bremen and proposes a scenario-based model to analyze the effects of the risk factors in collaboration network and supply chain performance during the transfer of work process.
The thesis includes the definition of key performance indicators, the description of a transfer of work process model and the identification of influencing factors on the key performance indicators.
Finally, the model will be tested and validated with transfer of work projects of other European repair shops. The general approach will be documented as a guideline, which can be used in future transfer of work projects in repair.
Manufacturing companies worldwide recognized the high potential of Industrie 4.0 in order to increasing production efficiency. Key benefits include creation of integrated systems, networked products and improvement of service portfolios. However, for many companies deriving and evaluating necessary measures to use Industrie 4.0 potentials represents a major challenge. This paper introduces the "acatech Industrie 4.0 Maturity Index" as an approach to meet this challenge. The development of multidimensional maturity model intents to provide companies an assessment methodology. The aim is to capture the status quo in companies in order to be able to develop individual roadmaps for the successful introduction of Industrie 4.0 and manage the transformation progressively.
