RBD calculation results include time-dependent and steady state reliability and availability indices as well as time-independent results. Time-specific indices are calculated as a function of time, whereas steady state indices correspond to long-run average (or infinite time) measures.

Indices are calculated using the failure and repair information for blocks. In the RBD calculation properties, you indicate whether you want to consider repair information for blocks in reliability-based calculations such as reliability, failure rate, and MTTF. This capability helps you to compare the effects of repairs on system performance measures.

The following topics categorize and describe supported RBD measures:
