crml-engine

Reference runtime/simulation engine for CRML.

Depends on crml-lang for the CRML models and validation.

Install

pip install crml-engine

CLI

Validate a scenario/portfolio document:

crml-lang validate examples/scenarios/data-breach-simple.yaml
crml-lang validate examples/portfolios/portfolio.yaml

Run a simulation:

crml simulate examples/scenarios/data-breach-simple.yaml --runs 10000
crml simulate examples/portfolios/portfolio.yaml --runs 10000
crml simulate examples/portfolio_bundles/portfolio-bundle-documented.yaml --runs 10000

Notes:

• The crml simulate command auto-detects scenario vs portfolio vs portfolio-bundle inputs.
• Portfolio simulation uses crml_lang.plan_portfolio and applies portfolio semantics.

Python

from crml_engine.runtime import run_simulation

result = run_simulation("examples/scenarios/data-breach-simple.yaml", n_runs=10000)
print(result.metrics.eal)
