An efficient method combining active learning Kriging and Monte Carlo simulation for profust failure probability

Fuzzy Sets Syst., 2020
For more and more complicated engineering structures, it is a challenge to efficiently estimate the profust failure probability based on the probability inputs and fuzzy state assumption.

An efficient Bayesian updating framework for characterizing the posterior failure probability

Mechanical systems and signal processing
Bayesian updating plays an important role in reducing epistemic uncertainty and making more reliable predictions of the structural failure probability. In this context, it should be noted that the posterior failure probability conditional on the updated ...

System failure probability evaluation using fault tree analysis and expert opinions in intuitionistic fuzzy environment

, 2020
In quantitative fault tree analysis of a system, exact failure probability values of components are utilized to calculate the failure probability of the system. However, in many real world problems, it is problematic to get precise and sufficient failure

Estimating Failure Probabilities

2019
System failure describes an undesired configuration of an engineering device, possibly leading to the destruction of material or a significant loss of performance and a consequent loss of yield. For systems subject to uncertainties, failure probabilities express the probability of this undesired configuration to take place.

Improved Bounds for System-Failure Probability

IEEE Transactions on Reliability, 1987
The inclusion-exclusion formula can be used to obtain upper and lower bounds on system-failure probability. This paper shows that the bounds can be improved by using information contained in them. Algorithms are provided to find the improved probability bounds, along with examples.

General Probability of System Failure

IEEE Transactions on Reliability, 1983
This paper presents a general method to determine probabilities of failure of any fixed subset of coherent system components under various conditions. The method uses a known reliability structure of the system and the known joint probability distribution of its components times-to- failure.

Procedure FAILURE — The computation of probability of failure

Advances in Engineering Software and Workstations, 1991
Summary: This article presents the description of the procedure FAILURE which may be used for the probability analysis of practically any reliability condition. The estimation of the probability of failures is based on the simulation method Monte Carlo.

Failure probability assessment and prediction of corroded pipeline under earthquake by introducing in-line inspection data

, 2020
Considering the transient ground deformation (TGD) and permanent ground deformation (PGD), uncertain modeling is proposed by multiple limit states with time-dependent corrosion growth and seismic damage, as well as the rehabilitation.

Conservative Estimation of Probability of Failure

11th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2006
The paper provides a review of how to estimate a probability of failure from a small sample of data, and shows that the usual estimators of the parameters of the cumulative distribution function are biased, and can lead to unconservative estimations.

Probability of Component or Subsystem Failure Before System Failure

IEEE Transactions on Reliability, 1983
Summary: A method of determining the probability of having a given set of components failed and another set of components working at the time of system failure is based on the notion of boundary probability. The method is simple and easily applied to any s-coherent system for which the reliability structure is known.
