This hampers understanding the state of language composition for researchers and practitioners. To mitigate this, we report the results of a literature review on modeling language composition operators. In this review, we identify operators, their properties, supported language dimensions, and relate them to the categories of language composition.

Moreover, we limited our search from January of 2012 to March 1st of 2022. For searching, we limited ourselves to the ACM Digital Library, IEEE Xplore, Springer, Scopus, and the Web of Science. We excluded Google Scholar for its well-known problems. Instead, we employed snowballing to identify potentially relevant literature that we might have missed in the initial search. Also, for the databases that did not support the search query as presented, we split the query into multiple queries and merged their results manually. For the ACM Digital Library, this resulted in three search queries, one for the keywords, one for the title, and one for the abstract. For Scopus, we similarly split the search query into three parts but could combine these parts using disjunctions. For Springer, we had to search for exact phrases, i.e., perform a search for each conjunction of the search terms separately. Finally, for the Web of Science, we could reuse the search query as presented with minor modifications. Other limitations did not affect our query. Since we had to use multiple overlapping queries for some of the libraries, the search on these libraries already resulted in duplicate findings. When manually merging the multiple queries for a single library, we removed the duplicate findings for that library. This resulted in 8.741 publications. However, across the different libraries, we again had duplicate findings. We first removed these 2.703 duplicates, resulting in 6038 publications. We then applied inclusion and exclusion criteria to keywords, titles, and abstracts to remove 5.915 publications, resulting in 123 English, potentially relevant, peer-reviewed publications. These publications we then analyzed in detail during the classification phase to understand if they were relevant to our study. Again applying our inclusion and exclusion criteria, this time to a deeper analysis of the publications, finally resulted in 28 publications. We then performed forward and backward snowballing resulting in 204 publications. Performing our analysis again, we found 11 publications presenting composition operators.

Using a modular, state-transition–based production planning framework, a factory is modeled in terms of machines, skills, and products, enabling the generation of feasible production plans under physical and logical constraints. Each skill execution is characterized by execution time, energy consumption, and reliability, allowing makespan, energy usage, and production risk to be jointly optimized. Within this setting, implementations of the A* graph-search algorithm, the Non-dominated Sorting Genetic Algorithm II (NSGA-II) evolutionary algorithm, and a Deep Q-Network (DQN)–based reinforcement learning approach are evaluated at the scheduling layer under identical conditions. Results from a representative case study reveal a fundamental trade-off between solution quality and computational effort: while A* guarantees optimal solutions at the cost of higher computation time, AI-based methods achieve high-quality, near-optimal solutions with significantly reduced planning time, making them well suited for complex, multi-objective scheduling problems. + +## Change Impact Analysis in Virtual Commissioning: Unified Continuous Parameterization of Robotic Systems (ETFA 2026) + +Virtual Commissioning (VC) links plant models and control software so that behavior can be validated before hardware is available. In robot-centric lines, kinematic, dynamic, and control parameters are tuned continuously. If these updates are not propagated traceably across Model-in-the-Loop (MiL), Software-in-the-Loop (SiL), and Hardware-in-the-Loop (HiL) environments, simulation and control can desynchronize. Classical Change Impact Analysis (CIA) and common toolchains primarily target discrete artifacts and repository events, but provide limited support for jointly governed numerical parameters. This paper addresses that gap through continuous parameterization. We propose an X-in-the-Loop (XiL)-oriented CIA workflow in which robot parameters are first-class, versioned configuration objects, graph-based checks encode admissible relations, and simulation and control remain aligned across XiL reconfigurations. Grounded in ISO~15288 and VDI/VDE~3693, the approach combines a five-step CIA process, a hierarchical three-tier runtime architecture (edge-local validation, central orchestration, and Git-backed persistence), and automated CI/CD pipelines that connect plant and controller models. Experiments on a six-axis Stäubli TX2-40 with per-axis Functional Mock-up Units (FMU) indicate stable synchronization between simulation and emulated controller under parameter adjustments, sub-millisecond full-axis constraint checks for interactive use, traceability from performance anomalies to parameter revisions, and robust operation during temporary connectivity loss via replicated state. + ## Tuning ROS 2 for Energy-Efficient Navigation: Empirical Insights from Costmap 2D Configurations (ICRA 2026) Robots are increasingly used in diverse application areas, where autonomous navigation plays a central role. As these systems become more widespread, improving their energy efficiency is critical to extending operational time and reducing environmental impact. The Robot Operating System (ROS) is a widely adopted middleware for robotics, offering a rich set of configurable packages. However, this flexibility can result in suboptimal software configurations in dynamic environments, negatively affecting both performance and energy consumption. This paper investigates the impact of ROS 2 package reconfigurations on the energy efficiency of mobile robot navigation. We conduct a controlled experiment in two warehouse-like scenarios (small and large) with varying obstacle layouts and Costmap 2D configurations (essential to the Nav2 stack). Through repeated trials, we measure energy usage, power profile, CPU load, memory consumption, and navigation performance. Results show that configurations must be carefully chosen for the specific robotic environment, and we were able to identify critical settings that lead to good and poor performance and energy consumption @@ -26,74 +34,4 @@ Digital twins enable optimization and flexibilityin cyber-physical production sy - [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/Towards_Formless_Production_with_Skill-Based_Industrial_Digital_Twins.pdf) -## A Container-based Approach For Proactive Asset Administration Shell Digital Twins (MODELS 2025) - -In manufacturing, digital twins, realized as Asset Administration Shells (AAS), have emerged as a prevalent practice. These digital replicas, often utilized as structured repositories of asset-related data, facilitate interoperability across diverse systems. However, extant approaches treat the AAS as a static information model, lacking support for dynamic service integration and system adaptation. The existing body of literature has not yet thoroughly explored the potential for integrating executable behavior, particularly in the form of containerized services, into or from the AAS. This integration could serve to enable proactive functionality. In this paper, we propose a submodel-based architecture that introduces a structured service notion to the AAS, enabling services to dynamically interact with and adapt AAS instances at runtime. This concept is implemented through the extension of a submodel with behavioral definitions, resulting in a modular event-driven architecture capable of deploying containerized services based on embedded trigger conditions. The approach is illustrated through a case study on a 3-axis milling machine. Our contribution enables the AAS to serve not only as a passive digital representation but also as an active interface for executing added-value services. - -- [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/A_Container-based_Approach_For_Proactive_Asset_Administration_Shell_Digital_Twins.pdf) - - -## On the Challenges of Integrating Digital Twins (EDTconf 2025) - -Digital Twins (DTs) are a key technology for smart ecosystems to provide accurate digital representation of their constituents, e.g., smart buildings, farms, transportation, and citizens, as well as synchronization between the digital and the real subject, and the exploration of what-if scenarios and trade-off reasoning.

After giving a historical overview of system adaptation, we review the many enabling technologies that can help with DT integration.

Despite their potential, the availability and application of Digital Twins in machine tools remain largely unexplored.

Our findings highlight the critical role of DTs in improving the efficiency and reliability of machine tools. - - -- [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/Digital_Twins_for_Machine_Tools_-_A_Systematic_Mapping_Study.pdf) - -## Towards a Unifying Reference Model for Digital Twins of Cyber-Physical Systems (ETFA 2025) - -Digital twins are sophisticated software systems for the representation, monitoring, and control of cyber-physical systems, including automotive, avionics, smart manufacturing, and many more. Existing definitions and reference models of digital twins are overly abstract, impeding their comprehensive understanding and implementation guidance. Consequently, a significant gap emerges between abstract concepts and their industrial implementations. We analyze popular reference models for digital twins and combine these into a significantly detailed unifying reference model for digital twins that reduces the concept-implementation gap to facilitate their engineering in industrial practice. This enhances the understanding of the concepts of digital twins and their relationships and guides developers to implement digital twins effectively. - -- [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/Towards_a_Unifying_Reference_Model_for_Digital_Twins_of_Cyber-Physical_Systems.pdf) - - - -## Navigating the Future - Essential Considerations for the Engineering of Software-Defined Vehicles (IEEE Computer) - -Software Defined Vehicles (SDVs) represent a transformative shift in the automotive industry, moving from traditional vehicle development to software-driven mobility solutions. The engineering of SDVs is inherently complex and involves numerous technological and organizational challenges. Future challenges include increased software complexity, managing software updates, cultural gaps, and complying with international standards and regulations. Additionally, the rapid pace of technological change demands an efficient and effective engineering process. To remain competitive and achieve their business goals, automotive organizations must adopt new strategies and undergo significant changes in the following software development concerns: architecture, process, and organization. These changes are necessary to boost productivity and improve the efficiency of the engineering process of SDVs. - -- [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/Navigating_the_Future_-_Essential_Considerations_for_the_Engineering_of_Software-Defined_Vehicles.pdf) - - - -## Two Decades of Automated AI Planning Methods in Construction and Fabrication: A Systematic Review (ACM Computing Surveys) - -Task planning and scheduling are crucial for construction or fabrication (CF) processes. Automating them is necessary for more efficient plans in terms of time and resources. However, most construction planning processes are still performed manually despite the existence of various AI methods. Symbolic AI automated task planning (ATP) techniques offer a variety of features to tackle task planning problems, but their application to CF has not been researched yet. This study identifies the current state of research and gaps in the literature regarding these AI techniques while providing directions for future research. We conduct a systematic review that evaluates existing literature on ATP in terms of environmental characteristics, modeling languages, ATP techniques, and results. We searched the ACM, IEEE, Scopus, WOS, and SpringerLink databases for papers published in the last 20 years (2002-2022) that discuss symbolic AI methods used in task planning within the CF fields. Our findings indicate that research on automated planning is currently limited regarding the characteristics of CF environments. Only a few papers have utilized symbolic languages, AI planners, and ATP techniques. No paper has evaluated their planning system in an on-site CF process. As a result, many symbolic languages, planners, and ATP techniques remain unexplored. -- [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/Two_Decades_of_Automated_AI_Planning_Methods_in_Construction_and_Fabrication_-_A_Systematic_Review.pdf) - -## Analysis and Review of Use Case Representations in OPC UA Companion Specifications - -For industrial data management, OPC UA data models are increasing in popularity.

These languages, with their differing levels of abstraction, exhibit distinct resource usage patterns, including power and energy consumption -an increasingly critical quality metric in robotics.Methods: In this study, we evaluate the energy efficiency of ROS 2 nodes implemented in C++ and Python, focusing on the primary ROS communication paradigms: topics, services, and actions.Through a series of empirical experiments, with programming language, message interval, and number of clients as independent variables, we analyze the impact on energy efficiency across implementations of the three paradigms.Results: Our data analysis demonstrates that Python consistently demands more computational resources, leading to higher power consumption compared to C++. Furthermore, we find that message frequency is a highly influential factor, while the number of clients has a more variable and less significant effect on resource usage, despite revealing unexpected architectural behaviors of underlying programming and communication layers. -- [Download the preprint](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/downloads/preprints/Energy_Efficiency_in_ROS_Communication_-_A_Comparison_Across_Programming_Languages_and_Workloads.pdf) - -## Digital Twins for Software Engineering Processes (ICSE 2025 NIER) - -Digital twins promise a better understanding and use of complex systems. To this end, they represent these systems at their runtime and may interact with them to control their processes. Software engineering is a wicked challenge in which stakeholders from many domains collaborate to produce software artifacts together. In the presence of skilled software engineer shortage, our vision is to leverage DTs as means for better representing, understanding, and optimizing software engineering processes to (i) enable software experts making the best use of their time and (ii) support domain experts in producing high-quality software. This paper outlines why this would be beneficial, what such a digital twin could look like, and what is missing for realizing and deploying software engineering digital twins. -- [Download the preprint](https://github.com/awortmann/awortmann.github.io/raw/master/downloads/preprints/Digital_Twins_for_Software_Engineering_Processes.pdf) - -## Identifying machine times with OPC UA for Equipment as a Service (CIRP CMS 2024) - -With Equipment as a Service (EaaS), subscription-based business models are becoming increasingly popular in mechanical and plant engineering. The main argument in favor for EaaS is a better overall equipment effectiveness (OEE) when a factory supplier operates the equipment. Therefore, the constant determination of the OEE in EaaS operations becomes crucial. This value is usually determined combining data retrieved from the equipment itself in combination with data from higher level systems like the manufacturing execution system (MES) of the customers. The latter are not accessible by the factory supplier. To bridge this information gap, the OEE of a piece of equipment is determined based solely on the available equipment data retrieved through data exchange standards such as the Open Platform Communications Unified Architecture (OPC UA). To achieve this, the time information needed to determine the OEE as defined in the ISO 22400-2 standard is either directly determined from OPC UA data from the machines or approximated through assumptions and exclusions. As an example for the mapping of equipment data to different time information, machine tools are focused and, hence, OPC UA 40501 and OPC UA 40001. In addition, the findings are analyzed regarding limitations in using the available time data via OPC UA. The mapping’s applicability is demonstrated with an exemplary use case and the OEE is compared when calculated only with equipment data retrieved via OPC UA with the OEE calculation having the additional information from a higher level system. This comparison allows to evaluate the uncertainty introduced by making assumptions and exclusions. The results are a valuable input to supplement the OPC UA Companion Specifications in order to cover the OEE determination in EaaS use cases. - -- [Download the preprint](https://github.com/awortmann/awortmann.github.io/raw/master/downloads/preprints/Identifying_machine_times_with_OPC_UA_for_Equipment_as_a_Service.pdf) -

By leveraging the MontiCore language workbench, the approach supports language extension, embedding, and aggregation, facilitating the creation of language product lines tailored to specific application domains. This reduces accidental complexity and promotes efficient model-driven development (MDD) by allowing domain experts to contribute using familiar terminology. The method enhances maintainability, reusability, and adaptability of DSLs, addressing challenges in engineering heterogeneous CESs. -[PDF](https://awortmann.github.io/downloads/paper/Language_Engineering_for_Heterogeneous_Collaborative_Embedded_Systems.pdf) | [Bibtex](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/_bibliography/andreaswortmann.bib) | Topics Cyber-Physical Systems Software Language Engineering +[PDF](https://awortmann.github.io/downloads/paper/Language_Engineering_for_Heterogeneous_Collaborative_Embedded_Systems.pdf) | [Bibtex](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/_bibliography/andreaswortmann.bib) | Topics Cyber-Physical Systems Software Language Engineering #### Maturity Evaluation of Domain-Specific Language Ecosystems for Cyber-Physical Production Systems The paper introduces a maturity evaluation model for domain-specific language (DSL) ecosystems in cyber-physical production systems (CPPSs), addressing the need for structured assessment of DSL maturity. The model evaluates nine components—grammar and syntax, semantics, naming conventions, style guides, libraries, patterns, analyses, tools, and documentation—using qualitative criteria. Applied to five CPPS DSLs (IEC 61499, SysML, MontiArc, IVML, PPR-DSL), the model reveals that all components are relevant, with SysML and MontiArc scoring highest in maturity. The study highlights the influence of community support and open accessibility on DSL ecosystem maturity, suggesting future research to refine and validate the model with industry practitioners. -[PDF](https://awortmann.github.io/downloads/paper/Maturity_Evaluation_of_Domain_Specific_Language_Ecosystems_for_Cyber_Physical_Production_Systems.pdf) | [Bibtex](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/_bibliography/andreaswortmann.bib) | Topics Cyber-Physical Systems Software Language Engineering +[PDF](https://awortmann.github.io/downloads/paper/Maturity_Evaluation_of_Domain_Specific_Language_Ecosystems_for_Cyber_Physical_Production_Systems.pdf) | [Bibtex](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/_bibliography/andreaswortmann.bib) | Topics Cyber-Physical Systems Software Language Engineering ### Software Language Evolution @@ -56,20 +56,18 @@ The paper presents a taxonomy of change types for textual domain-specific langua [PDF](https://awortmann.github.io/downloads/paper/A_Taxonomy_of_Change_Types_for_Textual_DSL_Grammars.pdf) | [Bibtex](https://raw.githubusercontent.com/awortmann/awortmann.github.io/master/_bibliography/andreaswortmann.bib) | Topics Software Language Engineering - ### Further Selected Publications - Pfeiffer, J., Rumpe, B., Schmalzing, D., & Wortmann, A.

The former involves abstract simulations of machine classes ("as-designed"), while the latter focuses on real-time representations of operational CPPS ("as-operated"). Bridging this gap is critical for seamless digitalization, as discrepancies arise from tolerances, environmental factors, and wear, causing "as-operated" systems to deviate from idealized models. Without continuous adaptation, these models lose predictive accuracy, leading to flawed analyses. To address this challenge, VC2DT aims to develop a methodology for the (semi-)automatic transformation of "as-designed" CPPS models into precise "as-operated" models during system commissioning, ensuring continuous alignment between simulations and real-world operational conditions. -### Publications +### Publications The complete list of publications is available from my [publications](https://awortmann.github.io/publications/) website. diff --git a/_projects/digital-twins.md b/_projects/digital-twins.md index 25c485e2..c3a6d24c 100644 --- a/_projects/digital-twins.md +++ b/_projects/digital-twins.md @@ -1,7 +1,7 @@ --- layout: page title: Systematic Engineering of Digital Twins -description: +description: img: /assets/img/project-digital-twins.jpg importance: 1 category: work @@ -12,20 +12,20 @@ Digital Twins of manufacturing systems should help to control production to redu ### Publications -- [Integration Challenges for Digital Twin Systems-of-Systems](https://www.se-rwth.de/publications/Integration-Challenges-for-Digital-Twin-Systems-of-Systems.pdf).

Many effects within the processes and in particular interactions (e.g., effect of component distortion on allowance, process forces and resulting surfaces, e.g., temperature control, microstructure generation or influence and subsequent component strength) have not yet been fully understood and currently elude comprehensive observation, control and process regulation due to a lack of metrological solutions and digital description approaches. Here, there is particular potential for the use of artificial intelligence and machine learning methods, as well as targeted and adapted software engineering. The goal should be to be able to describe the relationships in such a way that observation and adaptation of the processes and the process chain is made possible in such a way that the required properties (e.g., tolerances, surface and edge zone characteristics, strength, etc.) of the manufactured components are achieved with maximum process reliability. This requires the linking of several learning domains, e.g., by means of transfer learning. For this purpose, an explainable (XAI) method is to be designed and implemented. - ### Publications The complete list of publications is available from my [publications](https://awortmann.github.io/publications/) website. @@ -23,4 +22,4 @@ The complete list of publications is available from my [publications](https://aw ### Related Topics → [Digital Twins](https://wortmann.ac/dts/) -→ [Industry 4.0](https://wortmann.ac/i40/) \ No newline at end of file +→ [Industry 4.0](https://wortmann.ac/i40/) diff --git a/_sass/_themes.scss b/_sass/_themes.scss index ff1161c1..273e3402 100644 --- a/_sass/_themes.scss +++ b/_sass/_themes.scss @@ -11,7 +11,7 @@ --global-text-color: #{v.$black-color}; --global-text-color-light: #{v.$grey-color}; --global-theme-color: #{v.$blue-color-dark}; - --global-hover-color: #{v.$blue-color-dark}; + --global-hover-color: #{v.$blue-color-dark}; --global-hover-text-color: #{v.$white-color}; --global-footer-bg-color: #{v.$grey-color-dark}; --global-footer-text-color: #{v.$grey-color-light}; diff --git a/assets/jupyter/blog.html b/assets/jupyter/blog.html new file mode 100644 index 00000000..8eb10454 --- /dev/null +++ b/assets/jupyter/blog.html @@ -0,0 +1,7855 @@ + + + + + + + blog + + + + + + + + + + + + + + + +
