PyPI version Documentation Status Actions Status Language grade: Python Scc Count Badge Downloads LGPLv3 license DOI Donate Survey

reliability is a Python library for reliability engineering and survival analysis. It significantly extends the functionality of scipy.stats and also includes many specialist tools that are otherwise only available in proprietary software.

Documentation

Detailed documentation and examples are available at readthedocs.

Key features

  • Fitting probability distributions to data including right censored data
  • Fitting Weibull mixture models and Weibull Competing risks models
  • Calculating the probability of failure for stress-strength interference between any combination of the supported distributions
  • Support for Exponential, Weibull, Gamma, Gumbel, Normal, Lognormal, Loglogistic, and Beta probability distributions
  • Mean residual life, quantiles, descriptive statistics summaries, random sampling from distributions
  • Plots of probability density function (PDF), cumulative distribution function (CDF), survival function (SF), hazard function (HF), and cumulative hazard function (CHF)
  • Easy creation of distribution objects. Eg. dist = Weibull_Distribution(alpha=4,beta=2)
  • Non-parametric estimation of survival function using Kaplan-Meier, Nelson-Aalen, and Rank Adjustment
  • Goodness of fit tests (AICc, BIC, AD)
  • Probability plots on probability paper for all supported distributions
  • Quantile-Quantile plots and Probability-Probability plots
  • Reliability growth, optimal replacement time, sequential sampling charts, similar distributions, reliability test planners
  • Interactive matplotlib functions including crosshairs and distribution explorer
  • Physics of Failure (SN diagram, stress-strain, fracture mechanics, creep)
  • Accelerated Life Testing probability plots (Weibull, Exponential, Normal, Lognormal)
  • Accelerated Life Testing Models (Exponential, Eyring, Power, Dual-Exponential, Power-Exponential).
  • Mean cumulative function and ROCOF for repairable systems
