Smartification and digital refinement of products to enable the design of smart ones is a pivotal challenge in the manufacturing industry. Companies fail to design smart products due to missing knowledge of digital technologies and their integral part in product development processes. This paper presents a methodology that enables the derivation of digital functions for smart products through selected cases in manufacturing usage. We develop a morphology that consists of digital functions for smartification. In this context, we explained and derived characteristics by a set of examples regarding smart products in the manufacturing industry. Our methodology reduces the time spent initiating a development project with the focus on smartification.
The number of cyber-attacks on small and medium enterprises (SMEs) is constantly increasing. SMEs do not recognize the attacks until the damage has occurred. Only then, they fight with measures to increase IT-security and IT-safety. Many studies come to the point that this refers to a lack of budget, expertise and awareness of the need for IT-security. There are many compendia with recommendations for action, but they are too comprehensive and unspecific to the individual needs of SMEs. In this paper, we present the results of a research activity on the gaps that address the challenges faced by SMEs. In addition, we develop a concept for a serious gaming approach that includes an economic perspective on IT-security measures and shows how SMEs can derive their own IT-seurity target state
The aim of the related research project eCloud is to enable small and medium sized enterprises (SMEs) to implement flexible energy management without in-depth energy knowledge and with little distraction from day-to-day business, which is prepared for current and future challenges in the field of energy use. The overall result is a validated prototype for a plug and automate capable (i.e. without implementation effort) operational energy management, which can be successively set up in SMEs based on a cloud platform. Through its gradual and modular implementation, energy management meets the individual needs of each company and contributes to energy system transformation and climate protection by reducing energy costs and greenhouse gas emissions by up to 25%. In total, three expansion stages are available with the levels of monitoring, load management and grid usage, which consist of various Software as a Service (SaaS) modules from the cloud that can be retrieved as required. Thus, the user only needs a minimal hardware intervention in his production and saves a complex IT infrastructure. The methodology developed has been successfully applied by two user companies so far. This proves the effectiveness of the method.
Since 2016, the “Digital in NRW” Competence Centre has been supporting SMEs in the manufacturing industry in designing their individual digital transformation. With an Industry 4.0 maturity assessment, we define the status quo of SMEs, derive SME-specific measures from this, develop a digitalization roadmap and accompany the SME transformation. This paper presents the results of the four-year SME support. By analyzing the results of all maturity assessments, potential analysis and design workshops, we present the most frequent and most effective measures for a successful digital transformation of SMEs. The result of the paper is an action guideline for SMEs to initiate their own digital transformation based on formalized experience.
It is crucial today that economies harness renewable energies and integrate them into the existing grid. Conventionally, energy has been generated based on forecasts of peak and low demands. Renewable energy can neither be produced on demand nor stored efficiently. Thus, the aim of this paper is to evaluate Deep Learning-based forecasts of energy consumption to align energy consumption with renewable energy production. Using a dataset from a use-case related to landfill leachate management, multiple prediction models were used to forecast energy demand.The results were validated based on the same dataset from the recycling industry. Shallow models showed the lowest Mean Absolute Percentage Error (MAPE), significantly outperforming a persistence baseline for both, long-term (30 days), mid-term (7 days) and short-term (1 day) forecasts. A potential decrease of up to 23% in peak energy demand was found that could lead to a reduction of 3,091 kg in CO2-emissions per year. Our approach requires low finanacial investments for energy-management hardware, making it suitable for usage in Small and Medium sized Enterprises (SMEs).
Numerous traditional, agile and hybrid development approaches have been proposed for the development of CPS. As the choice of development process is crucial to the success of development projects, it has become a major challenge to identify the best-suited process. This paper introduces a methodology for identifying the best-suited CPS development process, based on the individual boundary conditions for a certain development project within a company. The authors used a set of eight indicators to assess a CPS-development project. The results of the assessment were matched with CPS-development approaches. Based on the matching results a best-suited development process was selected. The application is shown for a use case in the German manufacturing industry. The developed method aims to reduce the risk of project failure due to the wrong choice of development process.

Die Umsetzung von Industrie 4.0, also der umfassenden Digitalisierung und Vernetzung der Produktion, stellt Unternehmen noch immer vor Herausforderungen. In dieser Marktstudie wurde eine bei produzierenden Unternehmen identifizierte Hürde, die IT-Komplexität und deren Management, stärker beleuchtet. Unternehmen, die sich besser aufgestellt sehen, legen in der Regel einen stärkeren Fokus auf verschiedene Aktivitäten.
Digitally connected industrial production promises faster and more efficient processes - in development and production, services, marketing & sales and for adapting entire business models. Agility and the ability to make changes in real time are strategic chracteristics of successful companies in Industrie 4.0. To acquire these features, it is necessary to create a continuously expanding data base. However, a company's organisational structure and culture also play an important part in determining whether this data's potential is leveraged effectively.
This acatech STUDY describes a new tool for helping manufacturing enterprises to forge their own individual path towards becoming a learning, agile company. The acatech Industrie 4.0 Maturity Index is a six-stage maturity model that analyses the capabilities in the area of resources, information systems, culture and organisational structure that are required by companies operating in a digitalised industrial environment. The attainment of each development stage promises concrete additional benefits for manufacturing companies. The model's practical application was validated in a medium-sized company.
Die digital vernetzte industrielle Produktion verspricht schnellere und effizientere Prozesse - in Entwicklung und Produktion wie auch in Service, Marketing und Vertrieb oder bei Anpassung ganzer Geschäftsmodelle. Agil zu handeln und in Echtzeit Veränderungen vorzunehmen, wird in der Industrie 4.0 zur strategischen Erfolgseigenschaft eines Unternehmens. Voraussetzung dafür ist der Aufbau einer immer breiteren Datenbasis. Ob deren Potenzial effektiv genutzt wird, hängt jedoch auch wesentlich von der Organisationsstruktur und Kultur eines Unternehmens ab.
Die vorliegende acatech STUDIE stellt ein neues Instrument vor, mit dem produzierende Unternehmen den Weg zum lernenden, agilen Unternehmen individuell gestalten können. Der acatech Industrie 4.0 Maturity Index ist als sechsstufiges Reifegradmodell aufgebaut und analysiert die in der digitalisierten Industrie benötigten unternehmerischen Fähigkeiten in den Gestaltungsfeldern Ressourcen, Informationssysteme, Kultur und Organisationsstruktur. Jede erreichte Entwicklungsstufe verspricht produzierenden Unternehmen einen konkreten Zuwachs an Nutzen. Das Modell wurde in der praktischen Anwendung in einem mittelständischen Betrieb validiert.
Nowadays, the market for information and communication technologies used for IOT-applications grows daily. Since companies need technologies to transform their business processes corresponding to the digital revolution, they need to know which technologies are available, and fit the best for their use case. Their inertial issue is the lacking overview of technologies suitable to connect their production or logistics. Hence, this paper presents a methodology to select technologies (and combinations) based on their functions. It differentiates between information and communication technologies, digital technologies and connecting technologies by the physical function and its role in a cyber-physical system. Depending on the use case, the applicability of every technology varies. Due to that reason, the paper illustrates a ranked qualification of the technologies for typical use cases, focussing tracking and tracing issues in the intralogistics of producing companies. The evaluation is performed upon a literature research, a market study to identify suitable technologies, and various expert interviews to assess the applicability of the technologies.
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.

„Daten sind das Öl des 21. Jahrhunderts.“ Dieser Satz impliziert die große Bedeutung, die Daten heutzutage zugerechnet wird. Während die technischen Systeme immer ausgereifter werden und die Erzeugungsrate von Daten unaufhaltsam steigt, stehen viele Unternehmen, gerade im Produktionsumfeld, vor der Herausforderung, diese Daten zu nutzenbringenden Informationen zu verarbeiten.
In BigPro haben Experten aus dem Informations- und Kommunikationstechnik-Umfeld mit Anwendungspartnern aus der Fertigungsbranche zusammengearbeitet, um dieses Problem zu adressieren. Ziel des gemeinsamen Vorhabens war es, das Reaktionsmanagement von Störungen in fertigenden Unternehmen mittels Big-Data-Technologien zu verbessern und so die durch Produktionsausfälle entstehenden hohen Kosten zu reduzieren. Hierzu wurde eine Big-Data-Plattform entwickelt, die in der Lage ist, heterogene Daten aus unterschiedlichsten Quellen des Produktionsumfelds aufzunehmen, zu verarbeiten und in einen Kontext miteinander zu setzen. Neben den klassischen Datenquellen im Produktionsumfeld wurde die Datenbasis in BigPro um den „Sensor“ Mensch erweitert, um das digitale Abbild der Produktionsumgebung durch die Wahrnehmung, Stimmung und Sprache der Mitarbeiter noch transparenter darzustellen.
Durch den Einsatz der im Projektverlauf entwickelten Mustererkennung ist die BigPro-Plattform in der Lage, die generierten und gesammelten Daten expliziten Störungsmustern zuzuordnen. Diese bilden die Grundlage, aufgezeichnete Datenkonstellationen in Echtzeit mit bekannten Störungsmustern im Produktionsumfeld abzugleichen und bei sich anbahnender Übereinstimmung geeignete Maßnahmen einzuleiten, um den Störungen proaktiv entgegenzuwirken. Hierzu wurde ein Katalog mit störungsbehebenden Maßnahmen methodisch aufgebaut, aus welchem, je nach Anwendungsfall, manuell oder automatisch geeignete Maßnahmen initiiert werden. Eine Methodik, welche die Effektivität der Maßnahmen analysiert und bewertet, stellt sicher, dass etwa fehlgeschlagene Maßnahmen erkannt und überprüft werden können. Sollte für eine Störung keine geeignete Maßnahme hinterlegt sein, wird der Maßnahmenkatalog dynamisch durch situationsabhängig neu generierte Maßnahmen erweitert. Die Informationsbereitstellung sowie -rückführung des Reaktionsmanagements erfolgt in Form einer skalierbaren Visualisierung bedarfsgerecht für die unterschiedlichen Nutzergruppen. Durch ein hinterlegtes Eskalationsmodell werden den Mitarbeitern alle nötigen Informationen entsprechend der Maßnahme direkt und vor allem nutzerspezifisch (z. B. aggregiert für die Produktionsleitung, detailliert für den Analysten, etc.) zur Verfügung gestellt.
Die entwickelte BigPro-Plattform trägt durch die technologische Integration einer Störungsfrüherkennung, einem dynamischen Maßnahmenkatalog sowie einer bedarfsgerechten Informationsbereitstellung essentiell dazu bei, die von zunehmender Dynamik geprägte Produktion durch ein proaktives Reaktionsmanagement robuster gegenüber Abweichungen zu machen, um kostspielige Produktionsausfälle zu vermeiden.
Assessment of IS Integration Efforts to Implement the Internet of Production Reference Architecture
(2018)
As part of a collaborative network, manufacturing companies are required to be agile and accelerate their decision making. To do so, a high amount of data is available and needs to be utilized. To enable this from a company internal information system perspective, the Internet of Production (IoP) describes a future information system (IS) architecture. Core element of the IoP is a digital platform building the basis for a network of cognitive systems. To implement and continuously further develop the IoP, manufacturing companies need to make architecture-related decisions concerning the accessibility of data, the processing of the data as well as the visualization of the information. The goal of this research is the development of a decision-support methodology to make those decisions, taking under consideration the evaluated IS integration effort. Therefore, this paper describes the allocation of IS functions and identifies the effort drivers for the respective IS integration by analyzing the integration possibilities. Conclusively this approach will be validated in a case study.
Digitalization is changing the industrial landscape in a way we did not anticipate. The manufacturing industries worldwide are working to develop strategies and concepts for what is labelled with different terms such as the Industrial Internet of Things in the USA or Industrie 4.0 in Germany. Many industrialized economies are driven by the production sector and this sector needs specific approaches and instruments to take up other than those approaches we know from start-ups and ventures coming from Silicon Valley and other places. In this paper, we demonstrate an appropriate approach to transform producing companies in a systematic and evolutionary approach.
In particular, the objective of this paper is to provide results from two initiatives which conceptually build upon each other and are of particular relevance for the production industry. First, we present a global survey on the state of implementation and the future perspectives of the concept Industrie 4.0 from 2016. Findings from this study have forced parts of the German industry to heavily invest into a common approach to accelerate change towards Industry 4.0 in order to stay competitive in worldwide economy. This approach is presented in a second part.
Growing information systems (IS) often come along with growing IT complexity, because of emerging rag rug landscapes. This development causes rising IT costs and dependencies, which hinder the maintenance and expansion of the IS landscape. This article outlines the current research on published and presented methods to manage the rising IT complexity in a literature review. Because definitions of “IT complexity” vary a lot in literature, this paper also includes a definition of the term. In addition to that, it delivers a presentation of the used research methodology. Subsequently, it presents the findings in literature, highlights the research gap and – based on the literature analysis – presents the steps that need to be taken. A discussion of the results and a summary complete the article.
