Abstract
This paper extends the Birnbaum importance measure for a basic-event l evel to a gate-event level in a fault tree when statistical dependency between gate events exists, an explicit formula is given for gate rel iability importance (GR-Imp), and show how it can compute GR-Imp by us ing a conventional fault-tree algorithm, The computational algorithm f or GR-Imp is given along with numerical results for illustrative examp les.
