Mean Availability (All Events), [math]\displaystyle{ {{\overline{A}}_{ALL}} }[/math]

This is the mean availability due to all downing events, which can be thought of as the operational availability. It is the ratio of the system uptime divided by the total simulation time (total time). For this example:

[math]\displaystyle{ \begin{align} {{\overline{A}}_{ALL}}= & \frac{Uptime}{TotalTime} \\ = & \frac{269.137}{300} \\ = & 0.8971 \end{align} }[/math]
