ABSTRACT
Let us remind the reader of the definition of Birnbaum Importance Measure (BIM) [3] of system component j, j = 1, 2, ..., n. If system reliability is a function R = Ψ(p1, p2, ..., pn) of component reliability pj , we gave in Section 4.5 the following definition of BIM for component j:
BIMj = ∂Ψ(p1, ..., pn)
∂pj = Ψ(p1, ..., pj−1, 1, pj+1, ..., pn)− (10.1.1)
Ψ(p1, ..., pj−1, 0, pj+1, ..., pn).
