Representing Timed Automata and Timing Anomalies of Cyber-Physical Production Systems in Knowledge Graphs
Tom Westermann, Milapji Singh Gill, Alexander Fay
Model-Based Anomaly Detection has been a successful approach to identify deviations from the expected behavior of Cyber-Physical Production Systems. Since manual creation of these…
Structural Analysis of GRAFCET Control Specifications
Aron Schnakenbeck, Robin Mroß, Marcus Völker +2
The graphical modeling language GRAFCET is used as a formal specification language in industrial control design. This paper proposes a structural analysis that approximates the var…
Integration of Domain Expert-Centric Ontology Design into the CRISP-DM for Cyber-Physical Production Systems
Milapji Singh Gill, Tom Westermann, Marvin Schieseck +1
In the age of Industry 4.0 and Cyber-Physical Production Systems (CPPSs) vast amounts of potentially valuable data are being generated. Methods from Machine Learning (ML) and Data…
Unambiguous Interpretation of IEC 60848 GRAFCET based on a Literature Review
Robin Mroß, Aron Schnakenbeck, Marcus Völker +2
IEC 60848 GRAFCET is a standardized, graphical specification language for control functions. Because of the semiformal nature of IEC 60848, the details of specifications created wi…
Systematic Comparison of Software Agents and Digital Twins: Differences, Similarities, and Synergies in Industrial Production
Lasse Matthias Reinpold, Lukas Peter Wagner, Felix Gehlhoff +7
To achieve a highly agile and flexible production, it is envisioned that industrial production systems gradually become more decentralized, interconnected, and intelligent. Within…
Toward a Mapping of Capability and Skill Models using Asset Administration Shells and Ontologies
Luis Miguel Vieira da Silva, Aljosha Köcher, Milapji Singh Gill +2
In order to react efficiently to changes in production, resources and their functions must be integrated into plants in accordance with the plug and produce principle. In this cont…
A Graphical Modeling Language for Artificial Intelligence Applications in Automation Systems
Marvin Schieseck, Philip Topalis, Alexander Fay
Artificial Intelligence (AI) applications in automation systems are usually distributed systems whose development and integration involve several experts. Each expert uses its own…
A Control Flow based Static Analysis of GRAFCET using Abstract Interpretation
Aron Schnakenbeck, Robin Mroß, Marcus Völker +2
The graphical modeling language GRAFCET is used as a formal specification language in industrial control design. This paper proposes a static analysis approach based on the control…
A Capability and Skill Model for Heterogeneous Autonomous Robots
Luis Miguel Vieira da Silva, Aljosha Köcher, Alexander Fay
Teams of heterogeneous autonomous robots become increasingly important due to their facilitation of various complex tasks. For such heterogeneous robots, there is currently no cons…
Accessing and Interpreting OPC UA Event Traces based on Semantic Process Descriptions
Tom Westermann, Nemanja Hranisavljevic, Alexander Fay
The analysis of event data from production systems is the basis for many applications associated with Industry 4.0. However, heterogeneous and disjoint data is common in this domai…
Toward a Generic Mapping Language for Transformations between RDF and Data Interchange Formats
Aljosha Köcher, Artan Markaj, Alexander Fay
While there exist approaches to integrate heterogeneous data using semantic models, such semantic models can typically not be used by existing software tools. Many software tools -…
Concepts and Algorithms for Agent-based Decentralized and Integrated Scheduling of Production and Auxiliary Processes
Felix Gehlhoff, Alexander Fay
Individualized products and shorter product life cycles have driven companies to rethink traditional mass production. New concepts like Industry 4.0 foster the advent of decentrali…
A Mapping Approach to Convert MTPs into a Capability and Skill Ontology
Aljosha Köcher, Lasse Beers, Alexander Fay
Being able to quickly integrate new equipment and functions into an existing plant is a major goal for both discrete and process manufacturing. But currently, these two industry do…
Modeling and Executing Production Processes with Capabilities and Skills using Ontologies and BPMN
Aljosha Köcher, Luis Miguel Vieira da Silva, Alexander Fay
Current challenges of the manufacturing industry require modular and changeable manufacturing systems that can be adapted to variable conditions with little effort. At the same tim…
Model-Based Engineering of CPPS Functions and Code Generation for Skills
Aljosha Köcher, Alexander Hayward, Alexander Fay
Today's production systems are complex networks of cyber-physical systems which combine mechanical and electronic parts with software and networking capabilities. To the inherent c…
Integrating 2D and 3D Digital Plant Information Towards Automatic Generation of Digital Twins
Seppo Sierla, Mohammad Azangoo, Alexander Fay +2
Ongoing standardization in Industry 4.0 supports tool vendor neutral representations of Piping and Instrumentation diagrams as well as 3D pipe routing. However, a complete digital…
