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.
Unvorhergesehene Störungen gefährden in vielen Fällen den Kundenliefertermin. Die Produktionssteuerung hat die Aufgabe, effektiv und effizient auf diese kurzfristigen Störungen zu reagieren. Der Entscheidungsprozess beruht jedoch häufig auf einer qualitativen Analyse einer komplexen Situation anhand subjektiver Einschätzungen durch den Produktionsplaner. Zur Verbesserung der Entscheidungsfindung stellt dieser Beitrag eine App vor, die auf Basis von Echtzeitdaten und einer Simulation des Produktionssystems eine quantitative Entscheidungsfindung ermöglicht.
Die Variantenfließfertigung ermöglicht die Herstellung konfigurierbarer Produkte bei kurzen Durchlaufzeiten und geringen Beständen. Im Vergleich zu anderen Organisationsformen der Produktion gestaltet sich die Produktionsplanung und -steuerung aufgrund der Variantenvielfalt als anspruchsvoll. Im vorliegenden Beitrag wird der erste Schritt einer Methodik vorgestellt, welche für die Konfiguration der Reihenfolgeplanung entwickelt wurde.

Due to shorter product life cycles and the increasing internationalization of competition, companies are confronted with increasing complexity in supply chain management. Event-based systems are used to reduce this complexity and to support employees' decisions. Such event-based systems include tracking & tracing systems on the one hand and supply chain event management on the other. Tracking & tracing systems only have the functions of monitoring and reporting deviations, whereas supply chain event management systems also function as simulation, control, and measurement. The central element connecting these systems is the event. It forms the information basis for mapping and matching the process sequences in the event-based systems. The events received from the supply chain partner form the basis for all downstream steps and must, therefore, contain the correct data. Since the data quality is insufficient in numerous use cases and incorrect data in supply chain event management is not considered in the literature, this paper deals with the description and typification of incorrect event data. Based on a systematic literature review, typical sources of errors in the acquisition and transmission of event data are discussed. The results are then applied to event data so that a typification of incorrect event types is possible. The results help to significantly improve event-based systems for use in practice by preventing incorrect reactions through the detection of incorrect event data.
Companies operate in an increasingly volatile environment where different developments like shorter product lifecycles, the demand for customized products and globalization increase the complexity and interconnectivity in supply chains. Current events like Brexit, the COVID-19 pandemic or the blockade of the Suez canal have caused major disruptions in supply chains. This demonstrates that many companies are insufficiently prepared for disruptions. As disruptions in supply chains are expected to occur even more frequently in the future, the need for sufficient preparation increases. Increasing resilience provides one way of dealing with disruptions. Resilience can be understood as the ability of a system to cope with disruptions and to ensure the competitiveness of a company. In particular, it enables the preparation for unexpected disruptions. The level of resilience is thereby significantly influenced by actions initiated prior to a disruption. Although companies recognize the need to increase their resilience, it is not systematically implemented. One major challenge is the multidimensionality and complexity of the resilience construct. To systematically design resilience an understanding of the components of resilience is required. However, a common understanding of constituent parts of resilience is currently lacking. This paper, therefore, proposes a general framework for structuring resilience by decomposing the multidimensional concept into its individual components. The framework contributes to an understanding of the interrelationships between the individual components and identifies resilience principles as target directions for the design of resilience. It thus sets the basis for a qualitative assessment of resilience and enables the analysis of resilience-building measures in terms of their impact on resilience. Moreover, an approach for applying the framework to different contexts is presented and then used to detail the framework for the context of procurement.
Task-Specific Decision Support Systems in Multi-Level Production Systems based on the digital shadow
(2019)
Due to the increasing spread of Information and Communication Technologies (ICT) suitable for shop floors, the production environment can more easily be digitally connected to the various decision making levels of a production system. This connectivity as well as an increasing availability of high-resolution feedback data, can be used for decision support for all levels of the company and supply chain. To enable data driven decision support, different data sources were structured and linked. The data was combined in task-specific digital shadows, selecting clustering and aggregation rules to gain information. Visual interfaces for task-specific decision support systems (DSS) were developed and evaluated positively by domain experts. The complexity of decision making on different levels was successfully reduced as an effect of the processed amounts of data. These interfaces support decision making, but can additionally be improved if DSS are extended with smart agents as proposed in the Internet of Production.

Monetizing Industry 4.0: Design Principles for Subscription Business in the Manufacturing Industry
(2019)
Subscription business models have a major role for monetizing products and services for manufacturing companies in the age of Industry 4.0. As the manufacturing industry has difficulties generating revenues through digitalization, the implementation of innovative business models are essential to remain successful. Physical assets are often capital-intensive and require a more complex manufacturing process than subscription business models. Moreover, subscription models can focus on the individual customer benefit and a consistent service transformation, constituting a unique selling proposition and a competitive advantage. Hence, the following paper provides a management model that enables manufacturing companies to successfully realize the transformation towards a subscription business model. The management model presents four major fields of action, each matched with one design principle that must be considered when dealing with subscription models in the manufacturing industry. These principles were determined by an in-depth case study analysis among various manufacturing companies. Opportunities, challenges and recommendations for action were then systematically derived and integrated into the management model.
Eine wesentliche Bedingung zur Optimierung der Wertschöpfungsprozesse ist die Transparenz über die leistungsbestimmenden Faktoren eines Unternehmens. Die Ermittlung dieser Faktoren stellt für viele Industriebetriebe eine Herausforderung dar. Im Rahmen der Veröffentlichung wird daher eine Vorgehensweise zur systematischen Identifikation von Einflussfaktoren der Unternehmenskennzahlen vorgestellt, welche die Grundlage zur Ableitung von individuellen Stellhebeln zur Steigerung der Unternehmensleistungsfähigkeit darstellt.
Through data-based insights into customer behavior, products and service offers can be improved. For manufacturing companies, smart product-service systems (SPSS) offer the possibility to collect customer data during the usage phase of the product. As the focus on customer analytics is too often on sales and marketing, SPSS are overlooked as a source of customer data. However, manufacturing companies need to integrate data from all interactions with their customers along the complete customer journey to achieve a holistic data-based view of the customers. To identify these interactions and the customer data derived from them, the concept of a digital shadow will be applied to the customer journey. The projected results for the presented work in progress are a reference process model for the customer journey in manufacturing and a data model of the customer data created along this process.
In the age of digitalization, manufacturing companies are under increased pressure to change due to product complexity, growing customer requirements and digital business models. The increasing digitization of processes and products is opening up numerous opportunities for mechanical engineering companies to exploit the resulting potential for value creation. Subscription business is a new form of business model in the mechanical engineering industry, which aims to continuously increase customer benefit to align the interests of both companies and customers. Characterized by a permanent data exchange, databased learning about customer behavior, and the transfer into continuous innovations to increase customer value, subscription business helps to make Industry 4.0 profitable. The fact that machines and plants are connected to the internet and exchange large amounts of data results in critical information security risks. In addition, the loss of knowledge and control, data misuse and espionage, as well as the manipulation of transaction or production data in the context of subscription transactions are particularly high risks. Complementary to direct and obvious consequences such as loss of production, the attacks are increasingly shifting to non-transparent and creeping impairments of production or product quality, which are only apparent at a late stage, or the influencing of payment flows. A transparent presentation of possible risks and their scope, as well as their interrelationships, does not exist. This paper shows a research approach in which the structure of subscription models and their different manifestations based on their risks and vulnerabilities are characterized. This allows suitable cyber security measures to be taken at an early stage. From this basis, companies can secure existing or planned subscription business models and thus strengthen the trust of business partners and customers.
Prinzipien zur erfolgreichen Umsetzung von KI-Geschäftsmodellinnovationen
In Zeiten des zunehmenden globalen Wettbewerbs und hoch vernetzter Wertschöpfungsketten entwickelt sich Künstliche Intelligenz zu einem immer wichtiger werdenden Wettbewerbsfaktor für Unternehmen am Wirtschaftsstandort Deutschland. Durch den Einsatz von KI-Verfahren können nicht nur interne Geschäftsprozesse kostensenkend optimiert, sondern auch neue, digitale Geschäftsfelder und -modelle erschlossen werden. Es lassen sich zum einen Trends identifizieren, denen der Einsatz von KI in deutschen Unternehmen folgt. Zum anderen zeigt sich, dass sich KI unterschiedlich stark auf verschiedene Dimensionen innovativer Geschäftsmodelle auswirkt. Insgesamt lassen sich so Prinzipien ableiten, die die erfolgreiche Umsetzung von KI-Geschäftsmodellinnovationen beschreiben.
Neue Technologie- und Anwendungstrends kennzeichnen KI-Nutzung
Die tatsächliche KI-Landschaft in den Wertschöpfungsketten von KI-nutzenden Unternehmen ist durch Trends gekennzeichnet. Diese lassen sich in Technologie- und Anwendungstrends unterteilen. Experteninterviews zeigen beispielsweise, dass KI-Anwendungen bevorzugt auf Cloud-Infrastrukturen entwickelt und bereitgestellt werden. Das wiederum rückt die Frage nach der Wahrung der Datensouveränität in den Vordergrund. Anwendung findet KI tendenziell zur Prognose und Überwachung.
Sechs Prinzipien beeinflussen die erfolgreiche Umsetzung von KI-Geschäftsmodellinnovationen
Fallstudien über ein breites Spektrum der deutschen Wirtschaft beleuchten, welche Aspekte eines KI-basierten Geschäftsmodells den größten Effekt auf das Unternehmen haben. Hier lässt sich ein besonders hoher Einfluss von KI auf das Nutzenversprechen neuartiger, digitaler Leistungen der Unternehmen an die Kundinnen und Kunden feststellen. So lassen sich sechs Erfolgsprinzipien zur erfolgreichen Implementierung von KI-Technologien identifizieren, um die wirtschaftliche Nutzung von KI für Unternehmen in Deutschland im globalen Wettbewerb weiter zu steigern. So empfiehlt es sich zum Beispiel – neben der Auswahl des richtigen KI-Anwendungsfalles – ebenfalls darauf zu achten, dass die KI-Anwendung sowohl den Anbietenden wie auch den Anwendenden nützt. Diese und weitere Erfolgsprinzipien werden detailliert in der Studie Künstliche Intelligenz – Geschäftsmodellinnovationen und Entwicklungstrends beschrieben.
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.
Subscription business transforms traditional business models of machinery and plant engineering. Many manufacturing companies struggle to pull out the potential created by Industry 4.0 and make it economically usable. In addition to technological innovations, it is necessary to transform the business model. This leads to a shift from ownership-based and product-centric business models to outcome-based business models, which focus on the customer's value and thus realize a unique value proposition and competitive advantage – the outcome economy. Based on a case study analysis among manufacturing companies, this paper provides further clarification including a definition and constituent characteristics of subscription business models in machinery and plant engineering.
Subscription business models provide an important component for monetizing the potential of Industrie 4.0. Subscription business is based on a long-term and participative business relationship between customer and provider. However, only digitalization offers the necessary framework conditions to realize the characteristic recurring and performance-based billing, and to ensure the necessary transparency about the usage phase of products as well as continuous performance improvements in the customer process. Against this background, companies must not only recognize the much-cited potential that lies in the total dedication to the success of individual subscription customers. Rather, the central obstacles must be addressed, examined, and subsequently overcome in a targeted manner in order to successfully establish subscription business models and place them on the market.
The successful use of Business Analytics is increasingly becoming a differentiating competitive factor. The ability to extract data-driven insights and integrate them into decision-making is becoming growingly important. The underlying technologies are evolving exponentially, the value proposition differs from simple descriptive applications to automated decision-making. Existing approaches found in literature and practice to classify those levels only insufficiently mark down the boundaries between the different technology levels. As a consequence, it is often unclear which characteristics of the technology interact with the working environment, which can be described as a socio-technical system. Using a systematic literature review, this paper identifies the characteristics of Business Analytics and delineates three types of Business Analytics based on case studies. Thus, a starting point for the socio-technical system design and optimization for the use of Business Analytics is created.
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.
Discrete Event Simulation (DES) is a well-known approach to simulate production environments. However it was rarely used for operative planning processes and to our knowledge never in terms of multiple disposition levels.In this paper we develop the necessary adjustments to use DES for this purpose and show some theoretical advantages.
