This tech tool calculates availability and reliability of serial and parallel systems.

Availability is calculated in percentages, which is what availability is always specified (also known as nines notation).

Reliability is calculated in hours (also known as Mean Time Before Failure, MTBF).

It comes with an easy to use interface with entries controlled by sliders for all inputs including number of nodes, failure rate and mean time to restoration (MTTR). It does not require any keyboard entries.
