Ontology Supporting Model-based Systems Engineering based on a GOPPRR approach
The development process of modern systems is becoming increasing-ly complex. Model-based systems engineering (MBSE) has become the direc-tion of development in systems engineering. The basic element of MBSE is the model, which is developed using different modeling methods to formalize product development and the product itself (demand model, architecture model, etc.) throughout the lifecycle of system development. However, the use of dif-ferent modeling tools and modeling languages in different design phases leads to considerable deviations in the information between the models. The graph, object, point, property, role, and relationship (GOPPRR) modeling approach is developed based on reference models of different languages and is used to de-scribe the meta-models of different architectures, thereby enabling the use of models to describe products and product development. An ontology is used to represent the GOPPRR approach to implement a consistent representation of model information and further to implement data fusion in the lifecycle. Lastly, the feasibility of the modeling method and the ontology representation method was verified considering the braking system of an automatic driving system.
