risk analysis safety SysML system engineering

Login or register to tag items

Nowadays, risk evaluations of large embedded systems is a noteworthy activity in a global engineering process. It should actually interoperate with the system design and produce a large amount of coherent documentation. In order to alleviate this problems, the key idea of this work is to combine safety and design viewpoints.

This safety viewpoint allows safety engineers to describe :

• Preliminary Hazard analyses
• Fault tree analyses

Those analyses interoperate with SysML models.

This module is made of:

• A DSL (Domain Specific Language) to define the concepts
• A DSM (Domain Specific Modeler) to represent these concepts :
• Tabular PHA
• Graphical PHA
• Graphical PHA with SysML
• Fault Tree
• Tolerable Rate analysis layer
• SIL analysis layer
• Impacts analysis
• Safety libraries
