Template:BlockSim Analytical FT and RBD Plot Examples

Let's assume that the three components A, B and C follow failure distributions Weibull(Beta=1.5,Eta=1000), Weibull(Beta=1.1, Eta=800) and Exponential(MTTF=3000). The reliability for each components and the system at mission time =100 hours is shown in the figure below.

There are several plots available for analytic RBD and FT analysis. In system level, there are four plots available as show in the following:

Unreliability vs. Time

Reliability vs. Time

Probability Density Function

Failure Rate vs. Time

For the metrics, there are three kind of reliability importance plot available:

Reliability Importance vs. Time
