The Weibull Analysis module of Availability Workbench analyses historical failure and repair data by assigning probability distributions which represent the failure or repair characteristics of a given failure mode.
The failure distribution assigned to a given set of times to failure (known as a Weibull set) may be assigned to locations in the RCMCost location hierarchy or failure models in the AvSim module.
The Weibull Analysis Module analyses times-to-failure and time-to-repair data using the following distributions:
Exponential Distribution
1-Parameter Weibull Distribution
2-Parameter Weibull Distribution
3-Parameter Weibull Distribution
Bi-Weibull
Tri-Weibull
Lognormal Distribution
Normal Distribution
Weibayes
