Komplexe Anforderungen an das operative Supply-Chain-Management führen zu komplexen Entscheidungssituationen innerhalb des betrieblichen Alltags. Ein konzeptioniertes, modulares Simulationsmodell für das operative Supply-Chain-Management kann die Entscheidungsfindung auf Grundlage von Analysen und Daten unterstützen. Die Modularisierung ermöglicht eine flexible, effiziente und unternehmensspezifische Anwendung des Simulationsmodells. Die Modularität ist durch die individuelle Kombination geeigneter Module und Funktionen sowie der Abbildung dazugehöriger Informationsflüsse realisiert. Informationsflüsse werden dabei durch definierte Informationsobjekte, wie z. B. einen Fertigungsauftrag oder eine Maschine, spezifiziert. Die Module und Funktionen bilden die unterschiedlichen Prozessschritte ab.

By utilizing synchromodal relay transportation, it integrates multimodal logistics approaches to improve network efficiency and adaptability. Core functionalities include the detection and assessment of disruptive events, real-time route planning, and the use of AI to optimize multimodal transport routes. ReMuNet's collaborative platform fosters stakeholder coordination, ensuring capacity allocation and sustainable transport options. Pilot regions focus on geopolitical and ecological challenges, emphasizing lessons from past disruptions like the COVID-19 pandemic. This initiative aligns with the European Physical Internet vision, contributing to reduced emissions and robust freight logistics.
Circular economy (CE) is considered to be the business model of the future, since it enables decoupling of economic growth and resource consumption. Digitalization is an enabler for companies to accomplish the transition to circular business models, as it enables automated data sharing and usage, but it also poses an enormous challenge. The data required for the implementation of circular business models is generated during the entire life cycle of a product. Digital product passports (DPP) represent a solution for the exchange of product-related data across the entire life cycle and various stakeholders. So far, they have hardly been integrated into production planning and control (PPC) systems. This paper describes requirements, specific use cases and related data flows for an integration of DPP and PPC systems. Finally, a model is presented that enables event-driven creation and use of data for the bidirectional integration of DPP into PPC systems.
Transitioning to a circular economy fundamentally changes the traditional, linear economic model. Establishing circular strategies requires adapting and expanding the roles within the value system to realize the decoupling of economic growth and resource consumption. In particular, a combination of several value-retention strategies implemented in parallel can increase the ecological and economic potential of circular economy. However, there is a lack of description of this type of value system in relation to the new required activities, and the resulting material and information flows within the value system. For this reason, literature research and exploratory analyses through expert workshops were used to identify variants for implementing the value system. The results include the definition of five possible variants of a value system for the parallel implementation of value-retention circular strategies in the white goods industry. The five possible variants are necessary to enable sustainable collaboration strategies between different stakeholders from which all of the stakeholders can benefit. The new activities for enabling the various value-retention strategies, e.g., product evaluation or disassembly, are distributed differently across the stakeholders of the value systems per variant. This leads to distinct material and information flows per variant.
Die notwendige Transformation der Linear- zur Kreislaufwirtschaft ermöglicht die Entkopplung des Wirtschaftswachstums und Ressourcenverbrauchs. Das ökonomische und ökologische Potenzial der Kreislaufwirtschaft wird durch die zeitgleiche Umsetzung mehrere, simultaner Kreislaufstrategien gesteigert. Diese Umsetzungsform bedingt allerdings vielfältige und komplexe Entscheidungen für die operative Abwicklung. Das entwickelte kaskadierte Entscheidungsmodell differenziert diese Entscheidungen innerhalb verschiedener Ebenen des Wertschöpfungssystems.
Information-based Integration of Life Cycle Assessment into IT Landscapes of Manufacturing Companies
(2024)
Life Cycle Assessment (LCA) is one of the fundamental methods to facilitate effective decisions in sustainability transformation. However, the current implementation of LCA is inefficient due to detached software applications and manual data imports. Utilizing data from existing information systems offers the potential for a significant increase in efficiency. Existing approaches focus on prototypical implementations with a high level of detail but low transferability, or approaches only consider integration at the system level, whereby practical applicability is reduced. Therefore, this paper presents an information-based framework for integrating LCA software into the existing IT landscape of manufacturing companies with focusing on generic functions and a detailed information flow. The generic approach enables transferability, while the detailed information flows allow practical applicability.
In der Ära, in der Daten als „neues Gold“ bezeichnet werden, deckt eine Expertise die Kluft zwischen Erkennen und Nutzen dieses Schatzes auf. Sie bietet präzise Einblicke in die Datenmonetarisierung in Deutschland, legt verborgene Potenziale offen und liefert praxisnahe Handlungsempfehlungen, um produzierenden Unternehmen zu helfen, den wahren Wert ihrer Daten gewinnbringend zu nutzen.
In der Industrie wird die Digitalisierung der Wertschöpfungskette als einer der Schlüssel für hohe Wettbewerbsfähigkeit gesehen. Dabei sollen die Effizienz der Geschäftsprozesse gesteigert, neue Geschäftsmodelle erschlossen sowie regulatorische Vorgaben wie das Lieferkettengesetz umgesetzt werden. Es werden also IT-Systeme benötigt, die ein großes Funktionsspektrum abdecken, sich flexibel an sich verändernde Anforderungen anpassen lassen und dabei untereinander eine hohe Datendurchgängigkeit aufweisen. In der Realität erfüllen heutige Systemlandschaften diese Anforderungen selten.
Im Zentrum der IT-Systemlandschaften stehen häufig monolithische Systeme wie ERP und MES, deren sehr großer Funktionsumfang in Unternehmen nicht annähernd voll ausgenutzt wird, gleichzeitig jedoch relevante Unternehmensprozesse nicht abgebildet werden. Anpassungen und Erweiterungen der Systeme sind aufgrund heterogener Datenmodelle kompliziert und führen zu stark individualisierter Software mit Nachteilen in Betrieb und Wartbarkeit.
Ein entscheidender Erfolgsfaktor ist es, die Systemlandschaft zu modularisieren: Funktionalitäten werden in prozessual und aufgabenbezogen sinnvolle Funktionsmodule geclustert und Unternehmen nutzen jeweils die für ihre individuelle Auftragsabwicklung benötigte systemische Unterstützung.
Statt großer monolithischer Systeme werden also nur die tatsächlich benötigten Module eingesetzt. Die Funktionen innerhalb der Module weisen eine hohe Kohärenz auf, während Module untereinander eher lose gekoppelt sind. Durch eine geschickte Gestaltung und Orchestrierung der Module entsteht eine Systemlandschaft, in der keine Funktionsüberschneidungen vorliegen und die Datenhoheit in den Modulen klar definiert ist.
Companies in the manufacturing sector are confronted with an increasingly dynamic environment. Thus, corporate processes and, consequently, the supporting IT landscape must change. This need is not yet fully met in the development of information systems. While best-of-breed approaches are available, monolithic systems that no longer meet the manufacturing industry's requirements are still prevalent in practical use. A modular structure of IT landscapes could combine the advantages of individual and standard information systems and meet the need for adaptability. At present, however, there is no established standard for the modular design of IT landscapes in the field of manufacturing companies' information systems. This paper presents different ways of the modular design of IT landscapes and information systems and analyzes their objects of modularization. For this purpose, a systematic literature research is carried out in the subject area of software and modularization. Starting from the V-model as a reference model, a framework for different levels of modularization was developed by identifying that most scientific approaches carry out modularization at the data structure-based and source code-based levels. Only a few sources address the consideration of modularization at the level of the software environment-based and software function-based level. In particular, no domain-specific application of these levels of modularization, e.g., for manufacturing, was identified. (Literature base: https://epub.fir.de/frontdoor/index/index/docId/2704)
Process mining has emerged as a crucial technology for digitalization, enabling companies to analyze, visualize, and optimize their processes using system data. Despite significant developments in the field over the years, companies—notably small and medium-sized enterprises—are not yet familiar with the discipline, leaving untapped potential for its practical application in the business domain. They often struggle with understanding the potential use cases, associated benefits, and prerequisites for implementing process mining applications. This lack of clarity and concerns about the effort and costs involved hinder the widespread adoption of process mining. To address this gap between process mining theory and real-world business application, we introduce the “Process Mining Use Case Canvas,” a novel framework designed to facilitate the structured development and specification of suitable use cases for process mining applications within manufacturing companies. We also connect to established methodologies and models for developing and specifying use cases for business models from related domains targeting data analytics and artificial intelligence projects. The canvas has already been tested and validated through its application in the ProMiConE research project, collaborating with manufacturing companies.
