In Germany’s transition to a more sustainable industrial landscape, electricity generated by wind turbines (WT) remains a mainstay of the energy mix. Operating and maintenance costs, which account for roughly 25% of electricity generation costs in onshore WTs make improvements of maintenance activities a key lever in the economic operation of WTs. Prescriptive maintenance is a possible approach for improved maintenance activities. It is a concept where asset condition data is used to recommend specific actions and has great potential for the operation of wind parks. However, especially small, but also large wind park operators, and maintenance service providers often struggle with the implementation of such a new maintenance approach. As a part of the research project ReStroK, a learning game has been developed to support the training and familiarization of maintenance technicians with the concepts and underlying principles of this maintenance approach. In this paper, the concept for the development of a learning game will be presented. Multiple scenarios for its usage and their corresponding requirements will be discussed and an overview over the game will be given.
Augmented reality seems to offer great potential benefits in the field of industrial services. However, the question of the exact benefits, both monetary and qualitative, is difficult to evaluate, as is the case with IT investments in gen-eral. Within the framework of the DM4AR research project, an evaluation model was therefore developed. Based on group discussions and interviews on potential AR use cases, a list of monetary and qualitative benefits was compiled to form the basis for selecting suitable evaluation modules in the existing literature. These include an impact chain analysis in the form of a strategy map, a monetary eval-uation as a calculation of the return on investment, based on the assumptions of the use case as well as existing studies, and a qualitative evaluation in the form of a utility analysis. The outcome is an evaluation model in the form of a multi-perspective approach that considers the impact of AR in the four perspectives of the balanced scorecard (financial, customer, internal business processes, learning and growth). The results of the qualitative and monetary evaluation can be sum-marized in a 2D matrix to support decision-making.
Industry 4.0 and Smart Maintenance represent a great opportunity to make manufacturing and maintenance more effective, safer, and reliable. However, they also represent massive change and corresponding challenges for industrial companies, as many different options and starting points have to be weighed and the individual right paths for achieving Smart Maintenance need to be identified. In our paper, we describe our approach to evaluating maintenance organizations in a case study for the oil and gas industry, developing a shared vision for the future, and deriving economical and effective measures. We will demonstrate our approach, by showcasing a specific example from the oil and gas industry, where a need for action on HSE-relevant critical flanges in the company's piping systems was identified. We describe the steps, that were taken to identify the need for action, the specifications of the project and the criticality analysis of the piping system. This resulted in the derivation of a digitalization measure for critical flanges, which was first commercially analyzed and then the flanges were equipped with a continuous monitoring solution. Finally, a conclusion is drawn on the performed procedure and the achieved improvements.
Today, however, agility is seen more than ever as a critical success factor for companies. In times of an increasing degree of digital interconnection and minimum viable products, a mentality is entering the industrial service sector that has so far only been exemplified by Internet companies (e.g. Google): New products and especially digital services are developed in highly iterative processes. To this end, customers are involved in early test phases of development and provide feedback on individual functional modules, which – in contrast to the previous approach – are only gradually assembled into a market-ready “100 percent version”. But especially with the development of new digital services, companies must ensure more than ever that both the existing analog service business and the design of new digital services are geared to effectiveness and efficiency in order to meet the growing demands of customers and competitors.
To achieve this, companies must not only be familiar with the products currently on the market, but also master the entire product history, which in some cases goes back more than 30 years and varies greatly from one industry to another.
The transformation of the service technician into the customer's most important contact person and the company's most important sales channel requires a sustainable change of the entire company. But the effort is worth it. This insight has already reached many companies, but there is often a
lack of a clear idea of how much such a change challenges existing structures. A fundamental change of the company is only possible if all levels and departments recognize the necessity and have a clear idea of their future corporate culture. It is not enough to write down the new values of the company on a piece of foil, each employee must be able to understand and accept his or her own future role.
Reliability-centered maintenance for production assets is a well-established concept for the most effective and efficient disposition of maintenance resources. Unfortunately, the approach takes a lot of effort and relies heavily on the knowledge of individuals. Reliability data in Computerized Maintenance Management System (CMMS) is scarce and almost never used well. An automated risk assessment system would have the potential to contribute to the dissemination and effective use of risk information and analysis. The individuality of production setting, however, prevents current systems from being practically relevant for most industries. The presented approach combines ontologies to store and link knowledge, an information logistics model displaying the various information streams, and the Internet of production to take the different user systems and infrastructure layers into account. The provided model of a reference digital shadow for risk information and a detailed information logistics model will help software companies to improve reliability software, standardize and enable assets owners to establish a customized digital shadow for their production networks.

The maintenance department is an incubator for further developments in many companies and drivers for digital transformation. The basic essence of industry 4.0 is the optimisation of the information flows within and outside the company for accelerated adjustment of corporate organisations in the context of increasing competitive pressure. Due to the multitude of interfaces, information and data streams as well as their service characteristic, the maintenance department is ready to take the next step towards industry 4.0 and smart maintenance.
Despite endless publications and advertisements, the promise of smart maintenance is not technology but productivity. To achieve sustainable transformation, use cases need to be transformed into business cases. For that matter, lighthouse projects are not the key to success but transforming your departments, processes, data management, reporting and so on is. Another big misconception of industry 4.0: Transformational change does not happen with sensors or dashboards but with people. Therefore, companies which already invested in their people, culture and in lean six sigma have a head start. Nevertheless, it is no reason to rest. The journey to smart maintenance is long and no company can truly say that they achieved it already. In order to advance in industry 4.0 a digitisation roadmap is the best tool to show the big picture and at the same time link this vague vision to concrete measures. It is the only way to justify investment in infrastructure and guide your people into change.
But the first two questions on your way to smart maintenance are always the hardest:
1. What do I aim to achieve and how can industry 4.0 contribute to my goals?
What measure am I already pursuing to reach that goal and how do they further my aspirations?
Today, maintenance exceeds this definition, it is significantly more.
In many companies, it plays the role of an incubator for development
and drives digital transformation forward. The very essence of
Industrie 4.0 is the optimisation of the flow of information within as
well as outside of a company to accelerate the adjustment of company
organisations in the context of increasing competitive pressure.
Because of the variety of interfaces, information and data that
is available as well as its service character, maintenance lends itself easily as the area of choice for a company to make Industrie 4.0 real. Whilst doing so, the aim is not to equip employees with the
latest “gimmick“ for order processment or to be the company with
the highest number of lighthouse projects. Instead, maintenance
ensures reliable and cost-efficient production and, consequently,
the primary creation of added value of the manufacturing company.
Those who were identified as top performers during the “Smart
Maintenance“ consortium benchmarking by FIR at RWTH Aachen
University gain particular useful ideas twice as often as other follower companies directly from staff, thus releasing the right potential.
Information and data help to reach these goals and transfer the
vision of smart maintenance into actual pratice. But what is smart
maintenance exactly and how far along are you in the development
of your individual smart maintenance concept?
In order to cope with the challenges of an increased demand for flexibility, quality and availability of production, maintenance measures provide a major competiveness factor for manufacturing companies. Yet, interdependencies between maintenance and production activities as well as differing target systems within the functional units of an enterprise, especially production and maintenance, raise needs for extended coordination efforts. This paper aims to develop an innovative approach for the coordination between maintenance and production activities for industrial production companies. To achieve this, the novel coordination mechanism is used. It helps to achieve maximised operational availability— for a maximised output of the production system at optimal costs. Based on the developed model, the present paper identifies findings regarding the impact of different maintenance strategies on the medium-term economic efficiency of the production system.
Before starting with smart maintenance and machine learning, get things done right. Big data and analytics are a great way to get the most out of your assets, but they are not always the biggest lever and require a solid data foundation. As shown it is possible to get more out of the resources you have with relatively simple tools by applying the right method and bringing together the right people. To turn a computer system into a working tool and take full advantage of the capabilities of modern software solutions, specific steps must be taken, and both management and personnel need to be involved in shaping the future business processes. Only the right processes are able to generate a solid data foundation and enable the RCM method to work and improve asset lifecycle management and overall costs.
