Reliafy CLI

Reliafy CLI is a Python command-line tool for reliability analysis, reliability-based design optimization, and simulation workflows using profile-based configuration.

It supports First-Order Reliability Method (FORM), Second-Order Reliability Method (SORM), Inverse FORM, Inverse SORM, Monte Carlo simulation, and Importance Sampling for rare-event probability estimation. Workflows cover forward reliability evaluation, reliability-constrained design, and post-design simulation with a consistent problem-module interface and support for correlated non-normal variables via Nataf transformation.

Run outputs are designed for engineering decisions and reporting, including reliability metrics and design points, tabulated summaries (Excel/JSON), plot reports (PDF), and pickled Matplotlib figure objects for post-processing.

What Reliafy CLI Does

• Reliability analysis with FORM and SORM
• Reliability-based design with inverse FORM/SORM workflows
• Monte Carlo and importance sampling simulation
• Profile-based YAML configuration for repeatable runs

Install and Quick Start

On first use, Reliafy will prompt you to authenticate. If you do not already have an account, you can create one during the sign-in flow.

# Install from PyPI
pip install reliafy

# Show help
reliafy --help

# Copy packaged example problems
reliafy examples copy

# Run an analysis with the default profile
reliafy analyze default --include-sorm --plot-rfad

Profile Management

Profiles are YAML files under profiles/ that control run options.

# Create and edit a custom profile
reliafy profile new custom
reliafy profile nano custom
# or
reliafy profile vim custom

# Validate, list, copy, rename
reliafy profile validate custom
reliafy profile list
reliafy profile copy default mycopy
reliafy profile rename oldname newname

Requirements

• Python 3.10+
• Internet connection for API access and authentication

Testing and Validation

Unit and integration tests are provided in the tests/ directory.

# Run unit tests
python -m unittest discover tests -p 'test_*.py' -v

# Run integration tests with real API calls
RELIAFY_RUN_API_TESTS=1 python -m unittest tests.test_cli_api_integration -v

See the testing guide for details on test structure and rate limit behavior.

Notes

• Auth0 device flow uses public values (domain, client ID, audience). No client secret is used in the CLI.
