System Resilience Modelling, Simulation, and Assessment in Python

Python Structural Reliability Analysis

a general library for fatigue and reliability

SysMD is a SysML v2/KerML tool with an intuitive, notebook-style interface that makes getting started easy. What truly sets SysMD apart is its integrated solver, enabling engineering calculations directly within the model while automatically ensuring consistency across constraints and requirements.

100+ installable Claude skills covering Engineering areas such as, ISO 26262 functional safety, ISO/SAE 21434 cybersecurity, ISO 21448 SOTIF, AIAG-VDA quality (APQP/PPAP/FMEA), Automotive SPICE, and continuous improvement tools — every builder paired with a confirmation reviewer.

RAVEN is a flexible and multi-purpose probabilistic risk analysis, validation and uncertainty quantification, parameter optimization, model reduction and data knowledge-discovering framework.
