Analyzing Historical Data
Weibull Analysis is a method used to analyze historical failures and produce probabilistic failure distributions based on the data provided.
The distributions obtained by performing Weibull Analysis can be used in the AvSim and RCMCost Modules.
Exponential, normal, lognormal and Weibayes distributions are included in Availability Workbench alongside 1, 2 and 3 parameter Weibull, Bi-Weibull, Tri-Weibull and Phased Weibull distributions.
Using the Weibull Analysis Module
The Weibull Analysis Module is extremely easy to use; data may be entered manually by the user, imported from elsewhere or copied and pasted from the Windows clipboard.
You can then select a distribution and Availability Workbench will automatically fit this to the data provided. The result can be displayed graphically as a cumulative probability plot, unconditional probability density plot or conditional probability density plot.
