Some New Aspects on Component Importance Measures

  • Min Xie

Component importance measures are useful in deciding where to allocate further efforts to increase system performance, particularly system reliability and availability. Which of the components should be judged as important, and hence to be improved at the first hand, depends on the component structural position in the system, the improvement potential of the component and also the improvement action to be taken. In this paper we review some recent advances in measuring the importance of system components. A general methodology that incorporates these features is presented. We will also introduce some concepts concerning availability importance useful for repairable systems.
