Availability and Reliability

The Availability and Reliability report shows the technical availability, technical reliability and average operating time between failures.

Element

Description

Technical Reliability (TZUV)

Probability that a facility will operate correctly and free of failures. Does not take into account the impact of downtime after a fault occurs.

Technical Availability (TVER)

Probability of a facility being in a functional state at a given time. Takes into account the impact of downtime after a fault occurs.

Mean Time Between Failures (MTBF)

Average (mean) time between all failures over a selected time period. The lower this value, the lower the reliability, since the probability of failure occurring will be higher on average in between each failure.

Topological Chart: Technical reliability and technical availability are sorted according to the order of the facilities.

Pareto Chart: Technical reliability and technical availability are sorted by key performance indicators.
