Abstract

fetched live from OpenAlex

Model-based systems engineering (MBSE) has gained momentum as the predominant method of analyzing and deriving system requirements, as well as of verifying and validating system performance. Over the years, several frameworks have gained prominence as approved methods and formal techniques to model systems. MBSE technology continues to gain popularity within the systems engineering domain, especially in markets of complex systems. To remain relevant within the context of concurrent engineering, it is advantageous for system safety engineers to learn how these techniques are affecting system design so that safety is addressed within system development. This paper provides an overview of MBSE in theory and practice, and provides high-level details on how the system safety engineer can use these methods for optimum impact in affecting safety design.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
