A UAV Case Study on an MBSE Workflow with Integrated Modular Safety and Reliability Analysis

Abstract

This paper presents a model-based systems engineering (MBSE) workflow in compliance with aerospace safety standards, based on the new SysML v2 language and with particular focus on executable models. We extend the SysML modeling concepts by Component Fault Trees (CFTs) to form an integrated modular Model-Based Safety Analysis (MBSA) approach. We showcase our approach by an Unmanned Aerial Vehicle (search&rescue drone) and discuss how this approach can speed up the process and increase the consistency, modularity, and reuse of the design and safety analysis of the system.
