The Reliability Modeling Toolkit (RMT)

The Reliability Modeling Toolkit (RMT) is an R-based library of educational tools specifically designed to execute computationally involved and challenging reliability modeling and analytical calculations.

Documentation

• Documentation is included as standard R help files

Key Applications and Functions

• Probabilitsic physics-of-failure analysis
• Stress-Life, Strain-Life, Variable Amplitude Loading
• Fracture mechanics, wear, creep, and corrosion analysis
• Reliability Modeling: Probability plotting, least squares estimation of probability parameters, maximum likelihood estimation, Bayesian parameter updating
• Accelerated Life Testing
• Step-Stress Accelerated Life Testing
• Accelerated Degradation Testing
• Test Driven Development

Getting Started

Installation instructions from source for the RMT:

install.packages("devtools")
library(devtools)

• The cmdstanr library is required for installation and may not be available on CRAN so it will need to be installed manually first.

install.packages("cmdstanr", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))

• If Rtools is installed, build from source:

devtools::install_github("Center-for-Risk-and-Reliability/RMT", INSTALL_opts = "--install-tests")

• Otherwise, use the following:

devtools::install_github("Center-for-Risk-and-Reliability/RMT", build = FALSE, INSTALL_opts = "--install-tests")

Running Unit tests for RMT:

install.packages("testthat")
library(testthat)
library(reliabilityRMT)
test_package("reliabilityRMT")
