FMEDA failure-rate data & provenance
λD · diagnostic coverage · certified vs indicative
Pre-fills a SIF component's dangerous failure rate and diagnostic coverage from a curated, versioned FMEDA dataset, or imports a vendor's own FMEDA report as CSV tagged certified-tier — keeping certified vendor data visibly distinct from the platform's indicative library at every step.
เมื่อไรจึงใช้
- Building a SIF subsystem without a vendor FMEDA report on hand — start from the curated dataset.
- You do have a vendor-certified FMEDA report and want that provenance to carry through to the export.
- Auditing why a SIL number is trustworthy (or not) — the provenance tag is the answer.
ค่าที่ต้องกรอก
| ค่า | คำอธิบาย |
|---|---|
| Component / model | Matched against a curated-dataset entry, or replaced by an imported vendor CSV row. |
| Provenance tag | certified (vendor FMEDA) vs indicative (curated library) vs user-supplied — carried through to every downstream SIL number. |
คำนวณอย่างไร
The curated dataset is a versioned library keyed by component; a CSV import path maps a vendor FMEDA report's columns onto the same schema and stamps it certified, distinct from the platform's own indicative data.
ข้อควรระวัง
noteAn indicative curated failure rate is a reasonable planning number, not a substitute for the vendor's own certified FMEDA when one exists — the export makes which one was used explicit.
