Reliability analysis of retaining walls with multiple failure modes

Journal of Central South University, 2013
In order to reduce the errors of the reliability of the retaining wall structure in the establishment of function, in the estimation of parameter and algorithm, firstly, two new reliability and stability models of anti-slipping and anti-overturning based on the upper-bound theory of limit analysis were established, and two kinds of failure modes were ...

Reliability Analysis of Mechanical Component with Multiple Failure Modes

Transactions of the Korean Society of Mechanical Engineers A, 2013
Most products are indeed governed by multiple failure modes. However, there are few cases in which reliability analysis applies to only one failure mode at a time. Furthermore, reliability data do not include information about failure modes, or the reliability analysis is performed using a representative failure mode.

On the linear degradation model with multiple failure modes

Journal of Applied Statistics, 2010
The purpose of this work is to develop statistical methods for using degradation measure to estimate a survival function for a linear degradation model. In this paper, we review existing methods and then describe a parametric approach. We focus on estimating the survival function.

Analysis of two-machine lines with multiple failure modes

IIE Transactions, 2002
This paper presents an analytical method for evaluating the performance of production lines with a finite buffer and two unreliable machines. Unlike in earlier papers, each machine can fail in more than one way. For each failure mode, geometrically distributed times to failure and times to repair are specified.

Conditional failure profile analysis for multiple failure modes from incomplete two-dimensionalwarranty data

Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 2021
This paper addresses the issue of detecting dominating failure modes of a system from a two-dimensional warranty data set by analyzing conditional failure profile of the system. Two testing procedures have been proposed to test whether any of the failure modes is dominating at a particular time interval and whether there is a change of the failure ...

Selective Maintenance of Multi-Component Systems with Multiple Failure Modes

2020 Annual Reliability and Maintainability Symposium (RAMS), 2020
In this paper, we develop a novel selective maintenance framework for optimizing the reliability or economic performance of a multi-component system subject to multiple failure modes. We classify the failure modes into soft failures and hard failures (possibly dependent). Soft failures are defined as occurring when a degradation process under condition

Multiple Mode Protection Switching Failure Recovery Mechanism under MPLS Network

2010 Second International Conference on Modeling, Simulation and Visualization Methods, 2010
In order to solve the problem of constrained routing algorithm without capability of dealing with failures, this paper proposes a failure recovery method based on multiple mode protection switching including global protection???segment protection and local protection.

Reliability sensitivity analysis of mechanical parts with multiple failure modes

2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012
A reliability and reliability-based sensitivity analysis on mechanical parts with multiple failure modes is carried out in the proposed paper. Due to the unknown distributions of random variables, the first order second moment method are utilized to calculate the reliability of each failure mode.

Probabilistic modelling of free spanning pipelines considering multiple failure modes

Engineering Failure Analysis, 2019
Abstract Free Spanning occurs due to unevenness of seabed, artificial supports and etc. Based on DNV-OS-F101, free spanning may cause Vortex-Induced Vibration (VIV), local buckling and pipeline bursting. The purpose of this study is to present a methodology for assessing free spanning pipelines in terms of Probability of Failure (POF).

Fault diagnosis for multi-state equipment with multiple failure modes

2012 Proceedings Annual Reliability and Maintainability Symposium, 2012
Multi-state systems have received considerable attention recently with regards to reliability and maintenance. Since most mechanical equipment operates under some sort of stress or load, it tends to deteriorate or degrade over time, thus possibly resulting in discrete degradation states (damage degrees), ranging from perfect functioning to complete ...
