AADL-Based Safety Analysis Approaches for Safety-Critical Systems

Abstract

Ensuring system safety is significant for safety-critical systems. To improve system safety in system architecture models, Architecture Analysis and Design Language (AADL) is used to model safety-critical systems. My thesis provides several safety analysis approaches for AADL models. To make it more effective, model transformation rules from AADL models to target formal models are formulated for the integration of formal methods into safety analysis approaches. The automatic transformation can reduce the degree of application difficulty of formal methods for engineers.
