- Prozessanlagenplanung 2.0 - Netzarchitektur aus Verfahrensbeschreibung ableitenInfoDetails
Thomas Glock, Matthias Kern, Stefan Otten, Eric Sax, Martin Hillenbrand, Michael Hübner, 2016
Die Planung von elektrischen Kabelnetzen und die Auswahl von geeigneten Geräten, die die elektrische/elektronische Realisierung der Verfahrensbeschreibung (Rohrleitungs- und Instrumentenfließschema) in industriellen Prozessanlagen repräsentieren, erfolgt heute weitgehend manuell. Um den Aufwand zu reduzieren, die Kosten zu mindern und die Qualität zu erhöhen, sind modellbasierte Ansätze und Methoden, wie sie bereits in der Entwicklung von Elektrik-/Elektronikarchitekturen im Automobil eingesetzt werden, ein vielversprechender Ansatz. Dieser Beitrag stellt eine Methodik vor, die, basierend auf neuartigen Methoden und Werkzeugen, die Ableitung und Verwendung einer Vernetzungsarchitektur zur Planung von Industrieanlagen auf Basis der Verfahrensbeschreibung unterstützt.
- "Smarte" Sensoren in der FeldebeneInfoDetails
Thomas Glock, Martin Hillenbrand, Christoph Weiler, Michael Hübner, 2015
Zukünftige Kommunikationsnetzwerke industrieller Anlagen müssen die Anforderungen von Industrie 4.0 in der Prozessautomatisierung bewältigen. Innovative Ansätze für Kommunikation und Funktionalität können die mit I4.0 verbundenen Potenziale nur dann ausschöpfen, wenn sie einen industriell verwertbaren Mehrwert bieten. Dieser Beitrag stellt einen Ansatz vor, der einfache Sensoren und Aktoren der Feldebene um IP-Kommunikation sowie damit verknüpfte Dienste und Funktionen erweitert. Verbunden über ein industrielles Standard-IP-Netzwerk ermöglichen derartige Konstellationen zusätzliche Überwachungsfunktionen, die zu höherer Zuverlässigkeit und Verfügbarkeit der Anlagen beitragen können.

- Service-Based Industry 4.0 Middleware for Partly Automated Collaborative Work of CranesInfoDetails
Thomas Glock, Victor Pazmino Betancourt, Matthias Kern, Bo Liu, Thomas Reiß, Eric Sax, Jürgen Becker , IEEE 8th International Conference on Industrial Technology and Management (ICITM 2019), 2019
Industry 4.0 (I4.0) is characterized by a decentralized intelligence using service-based information technology. With the existing technologies in industrial solutions, the implementation of partly automated collaborative work of decentralized devices is difficult to achieve. Current industrial solutions fulfill manufacturer specific requirements that are not transferable to other industrial challenges. These customized solutions do not allow a plug-and-produce approach or a dynamically scalable system network. This work presents an approach for this through the use of a proposed service-based Industry 4.0 middleware. An example of its use is introduced in the form of the collaborative work of cranes, which handle the mentioned challenges. The proposed middleware is based on the service-oriented architecture with an evaluation of the I4.0 middleware using a demonstrator of collaborative work between cranes
- Model-Driven Design of Tools for Multi-Domain Systems with Loosely Coupled MetamodelsInfoDetails
Bo Liu, Victor Pazmino Betancourt, Thomas Glock, Matthias Kern, Eric Sax, J¨urgen Becker, The 13th Annual IEEE International Systems Conference (SYSCON), 2019
The influence of Internet of Things (IoT) and connected service-oriented systems in various application domains is increasing. Such multi-domain systems can work in collaboration to provide new functionalities. System development of different domains requires different specific tools that often lack common exchange interfaces. Common exchange interfaces between technical domains are necessary for a holistic architectural design that enables system-wide analysis, e.g. cyber-security. We propose a multi-domain metamodeling framework to create, extend and reuse metamodels of different technical domains in order to generate modeling tools for specific applications. The generated modeling tool enables analysis through all integrated domains. With loosely coupled metamodels, we are able to improve the reusability of the metamodels and manage the explicit connections using the weaving-model. This work also presents three use cases of application specific tools that can be built using the proposed framework: security analysis for industry 4.0 systems, multicore based safety systems and secure development of autonomous driving functions. The framework and a graphical editor to manage metamodel connections are implemented and used to generate modeling tools for the first two use cases. Our results show that a multi-domain system can be described precisely and analyzed across different domains with the specific generated tool.
- Fault tree-based Derivation of Safety Requirements for Automated Driving on the Example of cooperative Valet ParkingInfoDetails
Valerij Schönemann, Hermann Winner, Thomas Glock, Eric Sax, Bert Boeddeker, Geert Verhaeg, Fabrizo Tronci, Gustavo G. Padilla, 26th International Technical Conference on the Enhanced Safety of Vehicles (ESV), 2019
Developing safe vehicle automation systems is crucial for the commercialization of automated driving. One of the major challenges for the release of fully automated driving is functional safety. Automated driving systems explode in complexity due to an infinite number of occurring scenarios. Elaborated safety goals from a hazard analysis and risk assessment (HARA) are broad and more challenging to break down into safety requirements. This work presents a structure for a fault tree-based approach to derive safety requirements from safety goals systematically according to the international standard of functional safety for road vehicles known as ISO 26262. The methodology is applied on the example of automated valet parking (AVP). The approach simplifies the breakdown of complex safety goals and provides a more complete set of safety requirements.
- A Cybersecurity Risk Assessment Process for Model-Based Industry 4.0 DevelopmentInfoDetails
Matthias Kern, Thomas Glock,Victor Pazmino Betancourt, Bo Liu, Eric Sax, Jürgen Becker, 23th World Multi-Conferebce on Systemics, Cybernetics and Informatics (WMSCI), 2019
Cybersecurity risk assessments are important to define a welljustified cybersecurity concept that regards the trade-off between security, costs, and performance. Heading toward Industry 4.0 (I4.0), plants get connected with an increasing amount of sensors and functionalities that have more and more communication interfaces and paths. This leads to a growing cybersecurity attack surface and a higher complexity compared to current plants. Today, a well-structured course of action for a cybersecurity risk assessment is missing in the domain I4.0. Therefore, in this paper, a cybersecurity risk-assessment process containing an asset- , a threat- and an attack-analysis with adapted methodologies from other domains is proposed and the necessary terms for the approach are introduced. Furthermore, a model-based approach is proposed and its prototypical implementation supporting the proposed cybersecurity risk assessment process. Finally, the evaluation of the approach was done by applying it to an industrial use-case.
- Modellbasiertes Cyber-Security Risiko Assessment zur Entwicklung angriffstoleranter Industrie 4.0 SystemeInfoDetails
M. Kern, E. Taspolatoglu, V. Pazmino Betancourt, T. Glock, B. Liu, E. Sax, J. Becker , VDI Automation, 2019
Industrie 4.0 (I4.0) bietet durch eine hochgradige Vernetzung der Anlagen zahlrei-che Vorteile, denen neue Informationssicherheitsrisiken gegenüberstehen. Umso dringender sind modellbasierte Cyber-Security Risiko Assessments, die der wach-senden Komplexität von I4.0 Anlagen gerecht werden, notwendig. Treiber für die Komplexität sind die zunehmende Abhängigkeiten der Systemkomponenten unter-einander und die zunehmende Vernetzung über heutige Systemgrenzen hinweg. Dadurch entsteht auch eine größere Angriffsfläche. Bei der Bewertung von IT-Sicherheitsbedrohungen bieten aktuelle Standards wie z.B. die DIN EN 62443 Bei-spiele für Bewertungsmatrizen, die jedoch gerade in der Entwicklungsphase (Stichwort Security by Design) höchstens eine grobe Orientierung bieten. In diesem Beitrag wird ein Bewertungsverfahren aus dem Bereich Automotive auf I4.0 über-tragen und vorgestellt, das in einem modellbasierten I4.0 Entwicklungswerkzeug im vom Bundesministerium für Bildung und Forschung geförderten Projekt SysKit zum Einsatz kommt.
- Scenario-Based Development of an Industry 4.0 Domain Description Language for a Plant ArchitectureInfoDetails
Thomas Glock, Tobias Groß, Matthias Kern, Victor Pazmino Betancourt, Eric Sax, Jürgen Becker, IEEE - 7th International Conference on Industrial Technology and Management, 2018
By the introduction of industry 4.0 (I4.0), which is characterized by a decentralized intelligence as well as an autonomy of the product development, new challenges have arisen with regard to the existing technologies and planning of industrial plants. Most concepts developed are used by manufacturers of various branches themselves and have manufacturer specific scenarios, standards and requirements. This work presents the approach of a continuous scenariobased development of an I4.0 description language for an I4.0 industrial facility. The resulting metamodel is based on the service-oriented architecture and the Internet of things methodology. At the end of this paper, we will show how the metamodel is integrated and used in an I4.0 development tool.
- Model-based Validation and Testing of industry 4.0 plantsInfoDetails
Thomas Glock, Björn Sillmann, Max Kobold, Sebastian Rebmann, Eric Sax, IEEE - 12th Annual IEEE International Systems Conference (SYSCON2018), 2018
One of the major technical aspects of Industry 4.0 (I4.0) is the decentralized task and function distribution based on a service-oriented approach. This leads to new challenges by using the existing technologies and planning methods of I4.0 industrial plants. The validation of such dynamic serviceoriented architectures requires new validation methods to ensure the correct functionality of the I4.0 plant. The interactions of distributed functions and the integration of functions on several devices play an important role in planning, configuration, and validation of such plants. This work presents a new approach of a continuous model-based validation and testing method of I4.0 plant service-oriented architectures. The method allows to reuse existing functional tests of services and to adjust them with the help of the model-based information of a plant architecture model.
- A Multi-Objective Optimization Approach for Analysing and Architecting System of SystemsInfoDetails
Björn Sillmann, Thomas Glock, Raziyeh Ghassemi, Eric Sax, IEEE - The 12th Annual IEEE International Systems Conference (SYSCON2018), 2018
Electromobility is often associated with a limitation of the usual mobility. Original Equipment Manufacturers (OEM) try to reduce the drawbacks and to generate an added value by networking Electric Vehicles (EV) with other electric power systems. This corresponds to the concept of System of Systems (SoS). The characteristics of these are distinguished with the autonomy of the constituent systems, an evolutionary development and an emergent behavior of the SOS. Due to a high number of variants of constituent systems with different technical properties, the architecture process is a combinatorial optimization problem. Since traditional architecting methods are focused on stand-alone systems, they are not appropriate for developing those combinatorial SoS architectures. As a result, there is a need for a better architecting methodology, which reflects the SoS specific characteristics within the developing process. This paper presents a new methodology for searching, assessing and optimizing SoS architectures based on a genetic algorithm. The new methodology has been applied to a scenario of an energetic EV integration into a smart home environment.
- Scenario-based Functional Safety for Automated Driving on the Example of Valet ParkingInfoDetails
Valerij Schönemann, Hermann Winner, Thomas Glock, Stefan Otten, Eric Sax, Bert Boeddeker, Geert Verhaeg, Fabrizio Tronci, Gustavo G. Padilla, IEEE - Future Information and Communication Conference (FICC2018), 2018
New safety challenges have to be targeted due to the development of fully automated vehicles in the upcoming future. However, designing safe vehicle automation systems is essential. This work presents a scenario-based methodology for functional safety analysis according to the ISO 26262 using the example of automated valet parking (AVP). The vehicle automation system is decomposed into functional scenarios that can occur during operation. Potential malfunctions are identified for each scenario within a hazard analysis and risk assessment (HARA). Elaborated safety goals for automated valet parking are presented.
- Modellbasiertes Entwicklungswerkzeug für den Entwurf und die Analyse von angriffsresistenten Industrie 4.0 SystemenInfoDetails
Victor Pazmino Betancourt, Thomas Glock, Matthias Kern, Eric Sax, Jürgen Becker, VDI-Verlag, 2018
Die zunehmende Vernetzung sowie Dezentralität von Cyber-Physical Systems im industriellen Umfeld bietet ein hohes Potential und einen hohen Nutzen, wie z.B. eine effizientere Ressourcennutzung und Wartung der Anlagen, erhöht jedoch auch die Komplexität dieser Industrie 4.0 Systeme, welche durch verteilte Funktionsumfänge und globalen Informationsaustausch geprägt sind. Durch die hochgradige Vernetzung und die wachsende Komplexität werden die Systemgrenzen unschärfer und anfälliger für Angriffe, sodass Sicherheit eine Schlüsselrolle beim Einsatz und bei der Akzeptanz spielt. Um die Sicherheit von Industrie 4.0 Systemen ausreichend zu berücksichtigen, sollte diese bereits in den frühen Phasen des Systementwurfs betrachtet werden (Security-by-Design), um nachträgliche Maßnahmen mit hohen Kosten und großem Aufwand zu verhindern. Modellbasierte Werkzeuge, bei denen die Systeme und deren Sicherheitsaspekte modelliert und analysiert werden können, stellen einen geeigneten Ansatz zur Lösung dieser Problematik bereit. Dieser Beitrag präsentiert ein Konzept für eine modellbasierte Entwurfsunterstützung, die Security-by-Design für Industrie 4.0 Anlagen ermöglicht. Ziel der Entwurfsunterstützung ist, aktuelle und zukünftige intelligente Systeme angriffsresistenter entwickeln zu können
- Multi-Objective Optimization of System of Systems Architectures for Vehicle to Infrastructure Applications using an Evolutionary AlgorithmInfoDetails
Björn Sillmann, Kristina Gruber, Thomas Glock, Eric Sax, IEEE International Systems Engineering Symposium (ISSE), 2018
In future, Electric vehicles (EV) will play a key role for an affordable and sustainable mobility in urban areas. Today, Electric Vehicles are often associated with a limitation of the usual mobility. Original Equipment Manufacturers try to reduce the drawbacks and to generate added values by connecting EVs with other individual systems, like Household Components, Photovoltaic Systems, and Home Energy Storage Systems, which builds a connected Smart Home. This correspondents to the concepts of System of Systems (SoS) and Vehicle to Infrastructure (V2I) applications. Due to a high number of variants of constituent systems, the overall development of such connected systems gets a combinatorial optimization problem. Today’s engineering methods don’t address the challenges of finding the optimal SoS architecture. This paper presents a new engineering methodology for searching, assessing, and optimizing the SoS architecture for V2I applications. The new methodology is based on a Non-Dominating Sorting Genetic Algorithm II for an intelligent exploring of the trade space for finding optimal configurations of constituent systems and their interfaces. Therefore, a bitwise representation of SoS architectures is introduced. The methodology is validated at a real data set.
- Modellbasierte Planung und Konfiguration von verteilten Funktionsumfängen in der FeldebeneInfoDetails
Thomas Glock, Stefan Otten, Sebastian Rebmann, Eric Sax, VDI-Verlag, 2017
Die Planung und Konfiguration von heutigen Industrieanlagen sind mit existierenden Vorgehen und Planungswerkzeugen realisierbar. Im zunehmend vernetzten Umfeld und der damit einhergehenden Dezentralisierung von Funktionalitäten im Kontext von Industrie 4.0 bestehen Herausforderungen, die mit vorhandenen Verfahren und Techniken nicht bewältigt werden können. Insbesondere existieren keine Ansätze zur Planung, Analyse und Konfiguration von hybriden Anlagen, die eine Vereinigung von traditionellen und Internet of Things (IoT) Technologien beschreiben können. In diesem Beitrag wird ein Konzept vorgestellt, welches auf Basis von Methoden und Werkzeugen der Automobil-Entwicklung eine durchgängige, modellbasierte Beschreibung von dezentralen Funktionen, deren Verteilung auf Hardware sowie Analyse und Konfiguration unterstützt. Dies ermöglicht erstmals die gesamtheitliche Auslegung und Konzeption von hybriden Netzwerken in Industrieanlagen in frühen Produktentwicklungsphasen. Der Beitrag wird durch eine beispielhafte Anwendung und Validierung des modellbasierten Ansatzes an einem IoT-Demonstrator einer Mehrtankanlage abgerundet.
- Coping with the challenges of a rising complexity in context of a connected car with a continuous model of the System of Systems based on SysMLInfoDetails
Björn Sillmann, Thomas Glock, Eric Sax, EAEC2017 - 15th European Automotive Congress, 2017
As a result of more powerful communication technologies, individual systems are increasingly connected to System of Systems (SoS). In the automotive industry the SoS consists, among others, of the connected car, information technology (IT) backend systems and smart homes. Common characteristics of such systems are the autonomy of the constituent systems and the evolutionary development of the overall system with their distributed functionality. These lead to a rising complexity and increasing development risks over time. Therefore this is one of the biggest challenges in the automotive industry. Accordingly, there is a demand for the support of an efficient evolutionary development. This paper presents a methodological concept for supporting the evolutionary development of SoS. The main focus is on achieving a general system understanding. Therefore a continuous model of the SoS is introduced. This fosters the consideration of the current SoS for the development of new connected services and the reuse of existing services. In conclusion, this builds the basis for a more efficient development of new connected services.
- Analyzation and Evaluation of Vehicle and Infrastructure for Autonomous Driving on Public Transportation DepotsInfoDetails
Andreas Lauber, Thomas Glock, Eric Sax, Markus Wiedemann, 2016
After returning from the operation, buses are prepared for their next service at the depots of local transportation. The activities done at the depot includes smaller maintenance, inspection activities, and especially refueling and washing and interior cleaning of the vehicles. For the aforementioned activities, the buses are driven by a driver to the various stations at which the individual services are carried out. In addition to the staff employed at the stations drivers are required, which leaves the vehicle after completion of routine work on the overnight parking lots. Within this paper we present a study, which allows an autonomous driving on public transportation depots. The study address measures on the vehicles, the infrastructure of the depots, the safety of persons and vehicles and the legal situation in Germany. The proposed measures were chosen such that a variety of existing depots can be retrofitted for autonomous driving and also requirements and optimizations for future depots can be derived. Furthermore, attention was paid to generalize the proposed measures to facilitate later use outside the depot. Finally, this paper identifies economic impact of the system to the public transportation depot through the implementation of the proposed study. These are analyzations of expected savings that result from autonomous driving inside the depot.
- Ableitung von modellbasierten industriellen Vernetzungsarchitekturen aus dem Rohrleitungs- und InstrumentenfließschemaInfoDetails
Thomas Glock, Matthias Kern, Stefan Otten, Eric Sax, VDI Verlag GmbH, 2016
Die Planung von elektronischen Kabelnetzen, die die elektronische Realisierung der Verfahrensbeschreibung (Rohrleitungs- und Instrumenten Fließschema) in industriellen Prozessanlagen repräsentieren, erfolgt heute weitgehend manuell. Zu diesen Anlagen gehören zum Beispiel Raffinerien, kunststofferzeugende Fabriken und Lebensmittelgewerbe. Die Anforderungen an diese Anlagen sind unterschiedlich und liegen in der Regel nur als Text vor. Um den Aufwand zu reduzieren, die Kosten zu mindern und die Qualität zu erhöhen, sind modellbasierte Ansätze und Methoden, wie sie beispielsweise bereits in der Entwicklung von Elektrik-/Elektronik-Architekturen im Automobil eingesetzt werden, eine realistische Chance. Durchgängigkeit von den Anforderungen zur Realisierung, frühe Fehlerentdeckung und –behebung während der Planung von elektronischen Kabelnetzen sowie die Wiederverwendung von Bibliothekselementen sind das Ziel. So wird in diesem Beitrag dargelegt, wie mit Hilfe von Methoden und Tools der Automobil-Entwicklung neue Methoden für die unterstützende Planung von Industrieanlagen auf Basis der Verfahrensbeschreibung abgeleitet und genutzt werden können. Dabei fokussiert dieser Beitrag eine Methode zur automatisierten Erstellung von elektronischen Kabelnetzen (Vernetzungsarchitekturen) aus der Verfahrensbeschreibung. Ein Beispiel einer Mehrtankanlage, die als ein Bestandteil in Verfahren der Lebensmittelherstellung vorzufinden ist, rundet den Beitrag ab.
