RBD Calculations

Previous topic Next topic  

RAM Commander computes the reliability and availability of an RBD using one of the following methods:

Analytical

RBD is computed using analytical techniques, when possible.

Identical

This calculation is necessary when the RBD has elements that appear more than once in the diagram (if multiple diagram blocks have the same Ref.Des. field value, identical calculation assumes that it is the same block).

Monte Carlo

RBD is computed using simulation techniques, employing the distributions specified for each element.

MTBCF and R(t)

Calculates the RBDs’ mean time between critical failures and builds R(t) graph.
