The first step in a reliability optimization process is to
make a reliability assessment for each component in the system. If
this assessment is made in a qualitative way, by grouping together
components with the same reliability, and establishing a prevalence
order among groups, is there a way to decide which components
have the greatest Birnbaum measure without computing the exact
value of this measure? In this paper, three relations between com-
ponents are introduced and studied, and it is proved that they are
useful for selecting the components that have the biggest effect on
the system reliability in the sense of Birnbaum. An algorithm that
uses the results in the paper to select these important components
is also provided. |
