An Integrated System Design and Safety Framework for Model-based Safety Assessment
In recent years, technological advances have led to the design of complex and highly automated systems. While increased complexity has improved the performance and robustness of systems, it has also introduced new challenges. One of the core challenges lies in assessing the safety of such complex systems.
This presentation will introduce a model-based safety assessment framework, called the Integrated System Design and Safety (ISDS) framework, for assessing the safety of system design models early in the life cycle. The proposed framework combines a model-based safety analysis approach with a model-based safety verification approach to complete the safety assessment. The model-based safety analysis approach uses system design models defined in SysML to automatically generate Failure Modes and Effects Analysis (FMEA) tables and system fault trees. The model-based safety verification approach uses a simulation-based fault injection technique to perform safety verification. The presentation will discuss the results from the case study where the ISDS framework was applied to develop and assess the safety of a Forward Collision Warning (FCW) system.
Rahul Krishnan is PhD candidate in the System Engineering Program at Worcester Polytechnic Institute (WPI). He received a M.Sc. degree in Robotics Engineering from Worcester Polytechnic Institute (WPI) in 2017. His research is focused on applying Model-based Systems Engineering (MBSE) concepts to functional safety.
