# BlockSim Analytical Fault Tree and RBD Plot Examples

### From ReliaWiki

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 analytical RBD and fault tree analysis.

At the system level, there are four plots available as shown in the following:

##### Unreliability vs. Time

##### Reliability vs. Time

##### Probability Density Function

##### Failure Rate vs. Time

For the metrics, three kinds of reliability importance plots are available:

##### Reliability Importance vs. Time

##### Static Reliability Importance

##### Static Reliability Importance (Tableau)

At the block level, four kinds of plots are available:

##### Block Unreliability vs. Time

##### Block Reliability vs. Time

##### Block Probability Density Function
