Based on the increasingly complex value creation networks, more and more event-based systems are being used for decision support. One example of a category of event-based systems is supply chain event management. The aim is to enable the best possible reaction to critical exceptional events based on event data. The central element is the event, which represents the information basis for mapping and matching the process flows in the event-based systems. However, since the data quality is insufficient in numerous application cases and the identification of incorrect data in supply chain event management is considered in the literature, this paper deals with the theoretical derivation of the necessary data attributes for the identification of incorrect event data. In particular, the types of errors that require complex identification strategies are considered. Accordingly, the relevant existing error types of event data are specified in subtypes in this paper. Subsequently, the necessary information requirements and information available regarding identification are considered using a GAP analysis. Based on this gap, the necessary data attributes can then be derived. Finally, an approach is presented that enables the generation of the complete data set. This serves as a basis for the recognition and filtering out of erroneous events in contrast to standard and exception events.
Pricing is one of the most important, but underestimated tools, to enhance a company's profitability. Especially value-based pricing has a high potential to reach higher levels of satisfaction because it equates the needs of providers and customers. Even though, it is a well-known price model and promises higher satisfaction, many companies struggle to implement it. Especially the manufacturing industry is characterized by cost-plus pricing and competition-based pricing. However, especially for digital products these pricing strategies are insufficient. Therefore, this paper aims at exploring the design fields for value-based pricing of digital products in the manufacturing industry. To achieve this, the basics of digital products and value-based pricing are explored. Furthermore, an expert workshop is conducted that follows a framework for value-based pricing consisting of four consecutive steps analysis, price strategy, pricing, and market launch to capture the design fields. This paper concludes with limitations, and practical and research implications.
Today, manufacturing companies are facing the influences of a dynamic environment and the continuously increasing planning complexity. Using advanced data analytics methods, processes can be improved by analyzing historical data, detecting patterns and deriving measures to counteract the issues. The basis of such approaches builds a virtual representation of a product – called the digital twin or digital shadow.
Although, applied IT systems provide reliable feedback data of the processes on the shop-floor, they lack on a data structure which represents real-time data series of a product. This paper presents an approach for a data structure for the order processing which overcomes the described issue and provides a virtual representation of a product. Based on the data structure deviations between the production schedule and the real situation on the shop-floor can be identified in real time and measures to reschedule operations can be identified.
The steady increasing of supply chain complexity due to a rising global cross-linking of production and sales regions leads to an increasing sensitivity to disturbances while in the meantime the requirements of the availability, the time of delivery and the security of supplies within the supply chain increases. To meet this challenges the security of the supply chain infrastructure and the feasibility of supply chain processes need to be ensured, despite of the high specialization within the supply chain partners, the low stock and time buffers, and the information shortcoming between supply chain partners.
In this research, a System Dynamics simulation model, based on the manufacturing supply chain model of Sterman, has been developed for representing the actual complexity and dynamic in manufacturing supply chains. Therefore, the modeled manufacturing supply chain shows the processes of a four level supply chain focusing the processes and interactions of the mid-positioned two supply chain participants. The main contribution of the work described in this paper, is the description and implementation of necessary additional modules and parameters to Sterman’s basic model for the diagnosis of disturbance impacts as well as for the realization of supply chain adjustments. Finally, the model has been simulated and examined for realistic values.
In recent years supply chain participants are increasingly suffering the effects of disturbances in transportation supply chains. Both, dynamics in consumer demands and global supply chains lead to a growth in unplanned supply chain events. These can cause from rather manageable disturbances through to complete break-downs of transportation chains, resulting in high follow-up and penalty costs.
Consequently, concepts for an efficient supply chain disturbance management are needed, preferably with a real-time identification and reaction to disturbance events. Therefore in the following paper the research results of the German research project Smart Logistic Grids with the focus on designing an integrated model for the real-time disturbance management in transportation supply networks are presented. This includes the introduction of elaborated classification models for disturbances and action patterns as well as an associated costs and performance measurement system. Finally, a procedure model for the disturbance management is presented.
Industrial companies are moving to a solution driven business by offering smart product service systems (Smart PSS). In addition to an existing portfolio of physical goods and technical services, companies develop new digital services and combine all three offerings to an integrated digital solution business. While the development of new digital services does not pose any major challenges for companies, the successful sale of Smart PSS does. Due to changing customer requirements and value propositions of a solution, the sale of Smart PSS requires new design principles for the sales organization compared to the simple sale of physical goods or technical services. While there are already many publications on the topic of industrial sales in research, the description of Smart PSS in particular represents a new field of research. The combination of both topics is therefore not only interesting from a theoretical point of view, but also has a particularly high practical relevance and impact for industrial companies. This paper therefore describes on the one hand, which characteristics can be used to derive customer requirements for Smart PSS and on the other hand, which effects these requirements have on the sales organization of the industrial company. The design principles give recommendations for the organizational structure, the resources, the information systems and the culture of the company depending on the targeted customer type. In order to identify and describe both the customer requirements and the design principles, two morphological boxes were developed based on a literature research and semi-structured interviews with industrial companies. The paper gives an outlook on the different characteristics of the design recommendations and describes first best practices for the successful transformation of the sales organization.
Companies are transforming from transactional sales to providing solutions for their customers. Mostly, smart products, enabling companies to enhance their products by providing smart services to their customers, are a key building block in this transformation. However, the development of a smart product requires many digital skills and knowledge, which regular companies do not have. To facilitate the design and conceptualization of smart products, this paper presents a use-case-based information systems architecture prototype for smart products. Furthermore, the paper features the application and evaluation of the architecture on two different smart product projects. The use of such an architecture as a reference in smart product development serves as a huge advantage and accelerator for inexperienced companies, allowing faster entry into this new field of business.

In a subproject of the cluster of excellence “Integrative Production Technology for High-Wage Countries” at RWTH Aachen University a configuration logic is under development that enables companies to configure their production system according to the dynamic requirements of the market. As a result of this project, a holistic description model for production systems has been defined. With numerous attributes in the sub-models a detailed characterization of the production system is possible.
The sub-model for the design of the supply chain will be depicted in detail in this paper. Representative for the design of a supply chain, the spare parts logistics of the wind energy industry is analyzed in depth. Designing this supply chain is not only one of the most challenging tasks in logistics. Only a responsive but also cost efficient design of the spare parts supply chain guarantees high productivity, extended life spans of the wind turbines as well as the expected profit for all companies in the supply chain.
Assets of integrated production systems, especially in the heavy industry, are facing high requirements in terms of reliability and availability. In case of component breakdown, the operating firm is confronted with high costs due to downtime and loss of production. Modern maintenance concepts in combination with advanced technologies can help to improve the plant availability and reduce the downtime costs caused by unplanned breakdowns. Against this background, the research institutes FIR and IMR from RWTH Aachen University, Germany, are collaborating within the research project “SiZu”. This project deals with the integration of condition monitoring system and real time simulation to assess the condition of components and to support failure cause analysis.
The adoption of artificial intelligence (AI) technologies in manufacturing companies is challenging, particularly for SMEs that lack the necessary skills to develop and integrate AI-based applications (AI applications) into their existing IT system landscape. To address this challenge, the research project VoBAKI (IGF-Project No.: 22009 N) aims to enable SMEs to identify and close skill gaps related to AI application development and implementation using proper sourcing strategies. This paper presents the interim results from the second phase of the project, which involves identifying the tasks in the lifecycle of AI applications and determining the specific skills required for executing these tasks. The presented results provide a detailed lifecycle including the phases for the development and usage of AI applications, as well as the specific tasks that SMEs must consider when implementing an AI application. These results serve as the foundation for future research regarding the required skills to execute the presented tasks and provide a roadmap for SMEs to close skill gaps and successfully implement AI applications.
Die Dezentralität ist einer der bedeutsamsten Aspekte der Blockchain-Technologie. Dennoch gibt es große Unterschiede in der Dezentralität verschiedener Blockchain-Applikationen. Ziel der vorliegenden Arbeit ist es, eine strukturelle und funktionelle Durchdringung des Aspekts der Dezentralität zu erreichen und Eigenschaften zu finden, die es ermöglichen verschiedene Blockchain-Applikationen in ihrer Dezentralität zu differenzieren. Der vorliegende Beitrag legt dar, dass die Datenverteilung und die Zugangsberechtigungen (Lese- und Schreibzugang) entscheidende Eigenschaften für die Dezentralität der Blockchain Applikationen sind. Diese Eigenschaften werden mithilfe eine morphologische Analyse untersucht und es wird ein detaillierter Überblick über die verschiedenen Ausprägungen der genannten Eigenschaften und der Auswirkungen auf die Dezentralität gegeben.

Die verarbeitende Industrie in Deutschland steht vor der Transformation von der bisher vorherrschenden ökonomisch orientierten Produktion hin zu einer nachhaltigen Produktion. Durch die Anpassung von Parametern der Produktionsplanung und -steuerung, wie z. B. der Losgröße durch u. a. die Konsolidierung von Transportaufwänden oder geringe Reinigungsaufwände, kann dabei eine nachhaltigere Produktion erreicht werden. Hierfür wurde mittels einer systematischen Methodik ein digitaler Schatten konzeptioniert, der eine nachhaltige Konfiguration von Losgrößen ermöglicht. Dafür erfolgen eine Aggregation von Daten aus verschiedenen Informationssystemen und die Simulation des Verhaltens eines Produktionssystems bei veränderten Losgrößen. Diese ermöglichen eine optimierte Auslegung der Losgröße, basierend auf ökonomischen und ökologischen Zielgrößen.
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.

(2007)
Diese öffentlich verfügbare Spezifikation (PAS = Publicly Available Specification) beschreibt den Prozess- und Datenstandard myOpenFactory. myOpenFactory ist ein Standard für den elektronischen Datenaustausch zwischen verschiedenen ERP-/PPS-Systemen zur Koordination der überbetrieblichen Auftrags- und Projektabwicklung.
Ziel ist es, den Aufwand zum Informationsaustausch zwischen Unternehmen im Rahmen der Auftragsabwicklung nachhaltig zu reduzieren. Der Standard besteht aus einem standardisierten Prozess- und Datenmodell, das DV-technisch in verschiedenen ERP-/PPS-Systemen implementiert werden kann, und ist frei verfügbar. Für Kleinstanwender ohne eigenes ERP-/PPS-System existiert ein Web-Cockpit, das als einzige Voraussetzung eine Internetverbindung benötigt. myOpenFactory wird insbesondere im Maschinen- und Anlagenbau angewendet, kann aber auch in anderen Branchen zum Einsatz kommen. Durch den schlanken und gleichzeitig flexiblen Umfang der Schnittstelle ist myOpenFactory besonders für kleine und mittlere Unternehmen geeignet. Der Prozess- und Datenstandard wird von der myOpenFactory eG gepflegt und weiterentwickelt.
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.
Distributionslogistik
(2013)
Die Umgebung von Industrie- und Handelsunternehmen hat sich in den letzten Jahren tiefgreifend verändert. Beispielhafte Auslöser waren der Wandel vom Produzenten zum Käufermarkt, der faktische Wegfall der nationalen Grenzen und die damit verbundene Intensivierung des europäischen Binnenmarktes sowie die zunehmende Bedeutung ökologischer Anforderungen. Um die Kundenbedürfnisse dennoch befriedigen zu können und damit dem Wettbewerb gewachsen zu sein, müssen sich die Distributionsstrukturen der Unternehmen immer schneller an diese Veränderungen anpassen. Nur so können die Waren flexibel, kostengünstig und schnell an die Kunden geliefert werden. In diesem Spannungsfeld kommt der Planung und Steuerung der Distributionsabläufe eine immer wichtigere Bedeutung zu.
Ziel dieses Kapitels ist nicht nur die Vermittlung grundlegender Begrifflichkeiten und Zusammenhänge der Distributionslogistik, sondern weiterhin auch Methoden zur Distributionsplanung und steuerung sowie Kennzahlen zur Messung der Distributionsleistung und -kosten.
Produktionssysteme sind einer steigenden planungsbezogenen Unsicherheit und Störanfälligkeit ausgesetzt. Der hieraus resultierende überbetriebliche Koordinationsbedarf wurde hinsichtlich seiner Bewältigung in kontemporären Konzepten des Supply-Chain-Managements bislang methodisch nicht ausreichend berücksichtigt. Vor diesem Hintergrund gilt es ein geeignetes Werkzeug bereitzustellen, das die Planungsfähigkeit der Akteure sowie die Robustheit der Wertschöpfungskette als Ganzes steigert. Zu diesem Zweck soll der vorliegende Artikel einen Beitrag leisten, indem zunächst die relevanten Ursachen und Wirkungen planerischer Unsicherheiten aufgezeigt werden, um im Anschluss das darauf aufbauende Kooperationsmodell zu skizzieren.
