  1. 3. System reliability Objectives • Learn the definitions of a component and a system from a reliability perspective • Be able to calculate reliability of series, parallel and complex systems given the reliabilities of their components

  2. Definition of components and systems • Component: One failure mode, one performance function • System reliability: multiple failure modes, multiple performance functions • Block diagram: Shows effect of the failures of the components on the failure of the system

  3. Series systemCalculation of reliability • System fails if any one of its components fails … 1 2 n Independent components RS=R1…  Rn

  4. Parallel system: calculation of reliability • System survives if one component survives 1 2 n 3

  5. Generic approach for reliability analysis of complex systems • List all possible modes • Break down the event “system failure” into disjoint events • Calculate the failure probabilities of these events • System failure probability equals the sum of probabilities of the above events.

  6. Suggested reading • Thoft-Christensen, “System Reliability,” Engineering Design Reliability Handbook, CRC press, 2004, p. 15-1.
