“…OML serves as the core ontological language for the GitWorks platform and was originally developed by the Jet Propulsion Laboratory as part of the CAESAR project (Wagner et al 2020). One of the goals of CAESAR has been to provide a set of OML vocabularies that capture some of the common concepts and relations used in systems engineering (Bayer et al 2021). OML provides a foundation with well-defined semantics that can be used to model different types of engineering artifacts in a semantically consistent and interoperable fashion.…”

This paper reports on the development of GitWorks, an open platform for democratizated Model-Based Design of cyber-physical systems (CPS). The GitWorks platfor is currently under development by Perpetual Labs Ltd in collaboration with the Open Source Modelica Consortium (OSMC)1 and the OpenCAESAR project2. In this paper, we present our vision for the platform, its system architecture and a prototype implementation. We also present a case study that demonstrates the use of the proposed platform for enabling the seamless integration of Modelica models into a broader range of systems engineering processes for complex product development. In the longterm, the platform also aims to enable the integration of Modelica tools with advanced systems engineering processes that rely on other domain specific languages (e.g. SysML v2, BPMN, etc.).

“…Initially, the scope of MBSE encompassed modeling the architecture and requirements (Dubos et al, 2016). But after the Preliminary Design Review, it was decided to shift from MBSE back to a traditional documents-based approach (Bayer et al, 2021). While Power-, Thermal-, and Mass Budget were kept in openCaesar, architecture and requirements are since being designed in the traditional (i.e., not MBSE) way again.…”

“…The reason fell as 5 years into the mission’s development still only a partial implementation of the modeling tool and model existed which would not do. In a dedicated lessons-learned paper, Bayer et al reflect on the reasons for this failed application of MBSE (Bayer et al, 2021). They come to the conclusion that workforce training, creation of tutorials, writing the software framework, and applying these measures on a running project were simply too much to maintain a working and consistent system model.…”

“…They come to the conclusion that workforce training, creation of tutorials, writing the software framework, and applying these measures on a running project were simply too much to maintain a working and consistent system model. Another problem identified by Bayer et al (2021) is the inadequacy of existing tools for qualitative model analysis. The examples they provide for this statement are rather shallow, though.…”

Model-based systems engineering (MBSE) aims at creating a model of a system under development, covering the complete system with a level of detail that allows to define and understand its behavior and enables to define any interface and work package based on the model. Once the model is established, further benefits can be reaped, such as the analysis of complex technical correlations within the system. Various insights can be gained by displaying the model as a formal graph and querying it. To enable such queries, a graph schema is necessary, which allows to transfer the model into a graph database. In the course of this paper, we discuss the design of a graph schema and MBSE modeling approach, enabling deep going system analysis and anomaly resolution in complex embedded systems with a focus on testing and anomaly resolution. The schema and modeling approach are designed to answer questions such as What happens if there is an electrical short in a component? Which other components are now offline and which data cannot be gathered anymore? If a component becomes unresponsive, which alternative routes can be established to obtain data processed by it. We build on the use case of qualification and operations of a small spacecraft. Structural elements of the MBSE model are transferred to a graph database where analyses are conducted on the system. The schema is implemented by means of an adapter for MagicDraw to Neo4J. A selection of complex analyses is shown in the example of the MOVE-II space mission.
