The general approach is to capture the modeling effort with the use of Reliability Block Diagrams. The image to the right (click image) illustrates how a more complex system's configuration maybe represented by a Reliability Block Diagram. For each system the mission profile or usage profile varies.

Reliability Block Diagram (RBD)

A reliability block diagram (RBD) is a drawing and calculation tool used to model complex systems. An RBD is a series of images (blocks) representing portions of a system. Once the images (blocks) are configured properly and image data is provided, the failure rate, MTBF, reliability, and availability of the system can be calculated.
