Maintenance-Oriented Fault Tree Analysis of Component Importance

摘要

In this paper we investigate and compare a set of existing component importance measures and select the most informative and appropriate one for guiding the maintenance of the system. Efficient methods to compute the selected measure are presented. An important concern in the traditional fault tree reliability analysis, common-cause failure, is also addressed in the component importance analysis using the selected measure. A simple example is designed and analyzed to show the selection process.
