Die virtuelle Inbetriebnahme repräsentiert eine etablierte Phase des Lebenszyklus eines modernen Produktionssystems, in der die Definition von Simulationsmodellen eine Schlüsselrolle spielt. Im Falle von Montagelinien erfolgt die Layoutplanung in Iterationen mit geringem Automatisierungsgrad, wodurch die Phase des Engineerings sowie eine anschließende Erstellung des virtuellen Inbetriebnahme-Modells verlangsamt wird. In diesem Beitrag wird ein Konzept für einen modellbasierten Ansatz zur vollautomatisierten Planung von Montagelinien vorgestellt, womit eine automatisierte Modellerstellung für die virtuelle Inbetriebnahme durch eine Zuordnung von Montageprozessmodellen bezüglich kompatiblen Fähigkeiten der Betriebsmittel erlaubt wird.   Virtual commissioning represents an established phase in the life cycle of a modern production system, where the definition of simulation models plays a key role. In the case of assembly lines, layout planning is done in iterations with a low degree of automation, slowing down the engineering phase, and subsequent creation of the virtual commissioning model. In this paper, a concept for a model-based approach to fully automated planning of assembly lines is presented, enabling automated model generation for virtual commissioning by mapping assembly process models to compatible capabilities of the equipment.

Microgrid is a technically and economically viable opportunity to meet the demands of populations that, for various reasons, do not have access to electricity. The complexity of Smart Grid (SG) systems requires considerable engineering effort in the design process. Designing this type of complex system requires new approaches, methods, concepts and engineering tools. Where, requirements analysis plays a major role in better characterizing, understanding and specifying the domain of application that SG systems should solve. This work presents a systemic proposal based specifically on System Systems (SoS) which anticipates the formalization of requirements, aiming to understand, analyze and design SG within the scope of Model Based Systems Engineering (MBSE). The definition of a microgrid from the SoS perspective is presented in order to provide a complete view of its life cycle. Requirements would be represented in an Objective Oriented  Requirements Engineering (GORE) approach, specifically using visual diagrams based on the Keep All  Objectives Satisfied (KAOS) method, where network operation and control will be formally represented. A case  study for small communities in the equatorial Amazon forest is used as a case study for the proposed method.

This paper presents an approach to the utilization of model-based systems engineering (MBSE) early in the system lifecycle, which focuses on early identification of desirable system characteristics to support mission engineering (ME). The paper relies on the definition of an analysis approach and the associated mapping of architectural products. The analysis strategy focuses on integration of the results of operational simulations and system synthesis models through tradespace visualization. The architectural mapping presents the association of Systems Modeling Language (SysML) products to the analysis strategy. The coordination of these elements is presented as a demonstration of the role that MBSE concepts can play in support of ME. The approach is demonstrated through a case study analysis of a conceptual mine warfare system conducting mine countermeasure operations.

Inhalt Unscharfe Anforderungen, verschiedene Lösungs-alternativen oder eingeschränkt gültige Simulationsmodelle sind Beispiele für inhärente Unsicherheit in der Produktentwicklung. Im vorliegenden Beitrag wird ein modellbasierter Ansatz vorgestellt, der das industriell etablierte Denken in Sicherheitsfaktoren um qualitative Aspekte ergänzt. Modelle der Informationsqualität helfen, die Unsicherheit von Ent- wicklungsartefakten beschreibend zu charakterisieren. Mittels semantischer Technologien wird Unsicherheit so wirklich handhabbar – nicht im Sinne einer Berechnung, sondern im Sinne einer qualitativen Interpretation. Dadurch entsteht wertvolles Wissen für die iterative Anforderungsanalyse, die Bewertung alternativer System-Architekturen oder für die Rekonfiguration von Simulationen.
