What is Weibull Analysis?

Weibull Analysis is a statistical analysis that is used to determine reliability characteristics and trends from field and/or test failure data. It allows decisions to be made based on a limited amount of data. The Weibull distribution can be fit to datasets exhibiting an increasing, decreasing, or constant failure rate, a unique factor that separates it from other statistical distributions.

Results for a two-parameter Weibull Analysis provide estimates of an improving/degrading reliability trends and the characteristic life.

What’s the payoff?

Analysis results can be used to:

  • Determine warranty periods
  • Develop maintenance schedules
  • Determine spare parts inventory
  • Identify manufacturing issues
  • Reveal competing failure modes
  • Differentiate items used under different operations, conditions
