A continuum structure function (CSF) y is a non-decreasing mapping from the unit hypercube to the unit interval. Define whereas γ (γ) < α for all y < x}, the set of minimal vectors to level α. This paper examines CSFs for which each Pα is finite. It is shown that if γ is such a CSF and X is a vector of independent random variables, the distribution of γ (X) is readily calculated. Further, if γ is an arbitrary right-continuous CSF, the distribution of γ (X) may be approximated arbitrarily closely by that of γ′(X) where γ′ is a right-continuous CSF for which each minimal vector set is finite.

It is shown that, if γ admits of a modular decomposition, improved bounds may be obtained.

Continuum Structure

A continuum structure function γ is a non-decreasing mapping from the unit hypercube to the unit interval. Minimal path (cut) sets of upper (lower) simple continuum structure functions are introduced and are used to determine bounds on the distribution of γ (Χ) when X is a vector of associated random variables and when γ is right (left)-continuous. It is shown that, if γ admits of a modular decomposition, improved bounds may be obtained.

Definition Of

A continuum structure function is a non-decreasing mapping from the unit hypercube to the unit interval. A definition of the reliability importance, ℛi(α) say, of component i at system level α(0 < α ≦ 1) is proposed. Some properties of this function are deduced, in particular conditions under which and conditions under which ℛi(α) is positive (0 < α < 1).

Nondecreasing Mapping

A continuum structure function (CSF) is a nondecreasing mapping from the unit hypercube to the unit interval. The Kim-Baxter definition of the reliability importance of component i in a CSF at system level α, Ri(α), say, is reviewed. Conditions under which Ri(α) is positive, under which Ri(α) is a continuous function of α, and under which Ri(α) ≥ Rj(α) uniformly in α are presented. A simple algorithm for evaluating Ri(α) is described.

Nondecreasing Mapping

AbstractA continuum structure function is a nondecreasing mapping from the unit hypercube to the unit interval. This paper continues the author's work on the subject, extending Griffith's definitions of coherency to such functions and studying the analytic properties of a continuum structure function based on Natvig's ‘second suggestion’.

This paper is devoted to give several improvements of some known facts in lineability approach. In particular, we prove that (i) the set of continuous mappings from the unit interval onto the unit square contains a closed,c-semigroupable convex subset, (ii) the set of pointwise convergent martingales(Xn)n∈NwithEXn→∞isc-lineable, (iii) the set of martingales converging in measure but not almost surely isc-lineable, (iv) the set of sequences(Xn)n∈Nof independent random variables, withEXn=0,∑n=1∞var Xn=∞, and the property that(X1+⋯+Xn)n∈Nis almost surely convergent, isc-lineable, (v) the set of bounded functionsf:[0,1]×[0,1]→Rfor which the assertion of Fubini’s Theorem does not hold is consistent withZFC  1-lineable (it is not 2-lineable), (vi) the set of unbounded functionsf:[0,1]×[0,1]→Rfor which the assertion of Fubini’s Theorem does not hold (with infinite integral allowed) isc-lineable but notc+-lineable.
