FTG+PM: Describing Engineering Processes in Multi-Paradigm Modelling

Model-based System Engineering (MBSE) is a methodology that uses models throughout the engineering to replace the paper-based approach of communication among stakeholders. Multi-Paradigm Modelling (MPM) is at the core of this engineering approach as for each phase in the engineering process the most appropriate models at the most appropriate levels of abstraction is used. A design process includes a set of activities in which the design decisions or evaluations of the (sub-) system properties are done. Furthermore, the design artifacts are transformed by the design activities.We can define transformations as the manipulation of a model with a specific purpose. MPM approaches do not have a standard way of representing processes. A process model for MPM should focus on the languages, model instances and transformations between these models at different levels of abstraction. In this chapter, we propose the Formalism Transformation Graph and Process Model (FTG+PM) as a standard representation of MPM processes. The described process can be simulated for analysis and orchestration, as a set of (automatic) transformations.
