Fault tree analysis for quantitative reliability assessments

To identify and correct problems with reliability, maintainability, and safety at the component levels for government and commercial clients, Southwest Research Institute (SwRI) applies:

  • Analytical methods

  • Machine design expertise

  • Machinery and systems operational experience

System reliability engineering looks at the system as a whole and seeks to evaluate the inherent reliability at the system and component levels, the most likely single point failures modes and how they feed into the system fault tree, potential areas for reliability improvement, and appropriate actions to mitigate the effects of failures.


System reliability engineering support is provided during all phases of the product lifecycle, from conceptual design through prototype to aging equipment well beyond its original design life. A strong emphasis on probabilistic methods and the development and applications of physics of failure (PoF) models for failure rate estimation provides clients with high fidelity reliability assessments and remaining life forecasts.
