Modeling of Failure detection and recovery in SysML

Abstract

• Question — How can Failure Modes and Effects Analyses be generated from SysML models? • Motivation — Technical: Growing ubiquity, complexity, and safety criticality of systems containing software — Programmatic: Reduce cost and schedule burden of FMEAs to levels tolerated by developers and their management — Cultural: Growing use of SysML and • Method — Define success criterion and ensure model includes it — Create Structural models (primarily the system connections in internal block diagrams) that can be used to assess the success criterion — Create behavioral models for both normal flows and flows in the presence of simulated failures and cyber-attacks — Run simulations and log results — Analyze the logs and develop assessment artifacts.
