Summary
Description
<p>This project was a small proof-of-concept case study, generating SysML model information as a side effect of safety analysis. A&nbsp;prototype FMEA Assistant was used to semi-automate safety analysis that identifies failure modes and causes, using a library with standard SysML-compatible terminology to classify components associated with failure modes&nbsp;and to&nbsp;automatically identify candidate functions, infrastructure and failure modes. FMEA analysts select from standard functions and failures to systematically narrow down failure mode selection&nbsp;(presented in automatically created pick lists). Standard terminology from an existing Aerospace Ontology&nbsp;is used to&nbsp;classify components and automatically identify candidate functions and failure modes. With automatically created pick lists, analysts can easily and correctly select standard functions and failures for a SysML architecture&nbsp;model as a side effect of using FMEA Assistant.&nbsp;</p><p>A white paper reports on a concept&nbsp;for using&nbsp;SysML profiles for safety analysis, to&nbsp;standardize&nbsp;FMEA-related terminology&nbsp;for reuse in several types of safety analysis (hazard analyses, fault trees, reliability block diagrams).</p><p>See related project:&nbsp;&nbsp;Failure Modes and Effects Analysis (FMEA) Simulation Tool</p>
