Component Configurations

In order to construct a reliability block diagram, the reliability-wise configuration of the components must be determined. Consequently, the analysis method used for computing the reliability of a system will also depend on the reliability-wise configuration of the components/subsystems. That configuration can be as simple as units arranged in a pure series or parallel configuration. There can also be systems of combined series/parallel configurations or complex systems that cannot be decomposed into groups of series and parallel configurations. The configuration types considered in this reference include:

Series configuration.
Simple parallel configuration.
Combined (series and parallel) configuration.
Complex configuration.
k-out-of-n parallel configuration.
Configuration with a load sharing container.
Configuration with a standby container.
Configuration with inherited subdiagrams.
Configuration with multi blocks.
Configuration with mirrored blocks.

Each of these configurations will be presented, along with analysis methods, in the sections that follow.
