Digital Twinning in Product Development

Digital Twinning in Product Development

Development and use of experimental digital twins
Heiko Matheis ORCID Icon, Guido Grau, Florian Mews, Lukas Schüller
The development of textile products is associated with high material, time, personnel and cost expenditure. The paper describes the digital twinning for materials and processes and their application in a digital product development process, which can accelerate the ramp-up phase and thus reduce development costs by up to 60%.

Modeling Influences on the Wire Arc Additive Manufacturing Process

Modeling Influences on the Wire Arc Additive Manufacturing Process

Tim Sebastian Fischer, Lennart Grüger ORCID Icon, Ralf Woll
Wire Arc Additive Manufacturing (WAAM) is an additive manufacturing process which produces metallic components on the basis of arc welding. ISO/ASTM 52900 describes additive manufacturing as a process that creates components layer by layer from 3D model data. The basic equipment required includes a welding device, introducing the energy necessary for melting the metal wire, and a guiding machine, which traces the specified geometry of the component. Applications for WAAM include rapid prototyping and tooling, direct manufacturing and additive repair. The greatest advantages the process offers are low-cost system technology and a high deposition rate. The disadvantages of the process are the lack of process stability and exact repeatability. This article is intended to provide a clear overview of the WAAM manufacturing process, and to address its complex interactions.

Waste Heat Utilization through Thermal Cross-linking

Waste Heat Utilization through Thermal Cross-linking

A software solution for the development of optimized industrial energy concepts
Lukas Theisinger, Fabian Borst, Michael Georg Frank, Matthias Weigold, Andreas Maußner
The supply of production processes and buildings with thermal energy represents a significant share of the total energy demand of an industrial site. The use of industrial waste heat offers a way to reduce the external purchase of final energy. Due to the lack of transparency and the complexity of such measures, their potential often remains untapped. In the research project ETA im Bestand a user-oriented software solution was prototypically implemented. The software solution enables the development and evaluation of industrial energy concepts. Approaches from the research area of operations research and dynamic simulation are applied.

Process Modeling: Practice-Oriented and Methodologically Founded

Process Modeling: Practice-Oriented and Methodologically Founded

Jörg Becker ORCID Icon, Florian Schmolke ORCID Icon
Changes in the economic environment always generate new challenges for companies. In order to consider these challenges, it is necessary to have a comprehensive knowledge of the processes and a high level of transparency of the company's process organization. The process, represented in a documentation based on models, takes on a significant role as a reflection of the activities.

Effort and Benefits of IIoT Platforms

Effort and Benefits of IIoT Platforms

A systematic approach to identifying when to implement common use cases in SME
Rainer Eber, Steffen Schwarzer, Yannik Müller, Dennis Kollmann
SME often encounter risks and obstacles when implementing IIoT solutions, but these challenges can be mitigated with the use of an IIoT platform. To select the appropriate platform, a decision- making approach has been developed. By choosing the right use cases, companies can directly benefit from IIoT implementation and gain a competitive edge in the market. Our research indicates that at least three applications have a favorable balance between benefits and effort. Once successfully implemented, these applications can be expanded and scaled as the company becomes more digitally proficient.

Vom Energiedatenmanagement zum Digitalen Zwilling

Vom Energiedatenmanagement zum Digitalen Zwilling

Vereinfachte Modellierung eines Digitalen Zwillings mithilfe von Energiedaten
Alexander Blinn, Henrik te Heesen, Joachim Brinkmann, Julius Herzog
Bedingt durch globale Entwicklungen hinsichtlich der Preise und Versorgungssicherheit im Energiesektor stehen besonders energieintensive Unternehmen vor großen Herausforderungen. Zusätzlich fordern Kunden mehr Informationen über Energiekennzahlen und CO₂-Emissionen sowie ressourcenschonendere Prozesse. Mit einer energiedatenbasierten Simulationsmethode werden die Ressourceninformationen direkt aus dem Energiedatenmanagementsystem (EDMS) extrahiert und weiterverarbeitet. Hierbei werden sowohl aktuelle als auch stetig aktualisierte historische Daten verwendet, die automatisiert abgeglichen werden. Die digitale Abbildung der vorhandenen Prozesse ist lediglich auf Seiten der Energiedaten notwendig, ohne die technischen Prozesse in ihrer Gänze analysieren zu müssen. Mit dem so erstellten energetischen digitalen Schatten lassen sich Energiebedarfe für bevorstehende Produktionen und Produkte simulieren und können durch automatisierte Vorschläge in der Produktionsplanung positiv ...

The Compressed Enterprise-Control System Integration and the Era of Industry 4.0

The Compressed Enterprise-Control System Integration and the Era of Industry 4.0

How the digital control twin is changing operational applications and the integration of IT systems in a company
Wilmjakob Herlyn ORCID Icon
The Enterprise-Control System Integration of the operational applications is described in IEC-62264 and also referred to as the automation pyramid. This integration model is built on the MRP-II model developed in the 1980s. This model was groundbreaking for its time and still forms the basis of operational IT systems today. According to this concept, operational applications are run through hierarchically-sequentially (waterfall principle), which results in disadvantages such as: many interfaces, time delays, data loss, inconsistencies, etc. This sequential model neither meets the current requirements nor the informational and technical possibilities of Industry 4.0. It can be replaced by the concept of the digital control twin, which has corresponding effects on the automation pyramid.

Automated Detection of Fragile Production Behavior

Automated Detection of Fragile Production Behavior

Simple early detection of deterministic-chaotic behavior in highly available production systems
Martin Manns ORCID Icon, Denny Höhnen
Routing flexibility enables a robust, resilient design of production. However, in highly available, decentralized controlled production systems with cyclic material flow, it can reduce efficiency due to undesired deterministic-chaotic behavior. An automated method for measuring such behavior is presented. It is tested with a double conveyor belt laboratory system. An embedded system simplifies data acquisition. Results indicate that the method is usable for manual and automatic production systems. It has the potential to recognize modeling deficiencies in Industry 4.0 control with IEC 61499.

Modeling of Robust Processes

Modeling of Robust Processes

Requirements for process modeling
Annika Lange ORCID Icon, Thomas Knothe ORCID Icon
In order to withstand disruptions manufacturing companies need to improve their robustness. In the past only infrastructures and resources were considered in the context of robustness, neglecting the interconnectedness of processes. However, a consideration of processes in the context of robustness is highly relevant. Process modeling is used for the design and analysis of processes. This paper describes the requirements for modeling methodology and evaluates existing approaches. (Only in German)

Optimization of Line Feeding Strategy for the Assembly Line

Optimization of Line Feeding Strategy for the Assembly Line

A holistic approach for improving the intralogistics in production industry
Christina Braun, Lea Isfort
The logistics industry offers numerous opportunities for data-driven solutions, such as improving the part feeding problem in assembly line industries. A data-based approach for will lead to an improvement of cost-effectiveness through optimized processes, resource utilization, and consistent supply to the assembly line. The generated approach is a mixed integer programming model which considers limited storage space, uses constraints, and various cost factors related to transport, replenishment, and picking.
