Figure 1 - Interval based statistics

Figure 2 - Interval based statistics
With the parameters availability and MTTR, random distributions for disturbance durations (Erlang function) and distance of disturbances (negative exponential function) are automatically determined in the background
Calculation example:

Figure 3 - Example
The general formula is:
Availability = MTBF : ( MTBF + MTTR)
Level related to working time (when the object is working on a part)
With
MTTR: Mean-time-to-repair
MTBF: Mean-time-between-failures
