A SysML Profile for MIL‐STD‐882E (System Safety)

Abstract This paper presents a profile that extends the Systems Modeling Language (SysML) to support the requirements of MIL‐STD‐882E and facilitate the System Safety process. MIL‐STD‐882E is the U.S. Department of Defense (DoD) standard for System Safety Engineering (SSE). It mandates a series of analyses for hazard identification and tracking throughout system development, operation, sustainment, and disposal. These analyses are required to be documented in a series of reports set forth in the standard. For large systems, analyzing the system design and producing the mandated reports requires significant effort with a corresponding cost and resource impact on the overall program. Furthermore, while such analyses should be integrated with the development processes, they are often performed after design decisions are made and without the involvement of the primary development team. The System Safety Profile (SSP) presented here integrates the System Safety process with the design process by translating SSE concepts into structured elements within SysML, including representations of System Safety hazards, risks, mitigations, analysis activities, and the relations between them.
