Point Reliability shows the system’s point reliability over time. The point reliability is the probability that the system has not failed by time t. This is similar to point availability with the major exception that it looks only at the probability that the system did not have a single failure. Other (non-failure) downing events are ignored. It is very important to note that this value is not always the same as the reliability computed using the analytical methods, depending on the redundancy present.
Point Availability shows the system’s point availability over time. The point availability is the probability that a system (or component) will be operational (up and running) at any random time, t. Note that unlike reliability plots for analytical systems, the point availability measure incorporates maintainability information.

Simulation Fault Tree Point Availability Plot

Point Availability shows the system’s point availability over time. The point availability is the probability that a system (or component) will be operational (up and running) at any random time, t. Note that unlike reliability plots for analytical systems, the point availability measure incorporates maintainability information.
