Use of SysML for the creation of FMEAs for Reliability, Safety, and Cybersecurity for Critical Infrastructure

A method for producing a Failure Modes and Effects Analysis (FMEA) from SysML is presented together with a simple critical infrastructure system example. The significance of the method is the modeling of failure propagation which enables not only an automated approach but significant additional analysis results that can be used to support reliability, safety, and cybersecurity. The analysis products from a tool implementing this method together with the insight and analytical benefits they provide are discussed.
