Synchronization of System Architecture and Safety Models: a Proof of Concept

To face the increasing complexity of technical systems, engineers are designing models. The integration of models coming from various engineering disciplines, such as system architecture, multi-physics simulation, automatic code generation as well as safety and performance analyses, is one of today’s industrial challenges.In this article we present model synchronization - a framework to ensure consistency between models coming from different engineering domains, based on S2ML (System Structure Modeling Language). We illustrate our purpose using an Electro-Mechanical Actuator (EMA) of an aileron for a small aircraft. We show how the introduced framework can be used to handle consistency between system architecture models (represented in SysML) and safety models (represented in AltaRica 3.0) with several architecture variants.
