On the linear degradation model with multiple failure modes
Journal of Applied Statistics, 2010The 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.

The impact of multiple failure modes on estimating product field reliability
IEEE Design & Test of Computers, 2006A difficulty in reliability modeling is how to capture the impact of all of the various reliability defect types. The general approach to optimizing burn-in that we describe in this article addresses a multiple-defect environment. The approach has four main parts: (i) modeling the product's failure rate distribution, (ii) establishing the Pareto ...

Hedging-point production control with multiple failure modes
IEEE Transactions on Automatic Control, 1995Summary: We consider the control of a production facility subject to multiple failure modes. Motivated by work of \textit{R. Akella} and \textit{P. R. Kumar} [IEEE Trans. Autom. Control AC-31, 116-126 (1986; Zbl 0579.90047)] and \textit{T. Bielecki} and \textit{P. R. Kumar} [Oper. Res. 36, No.

System Reliability Assessment for a Rock Tunnel with Multiple Failure Modes
Rock Mechanics and Rock Engineering, 2012This paper presents a practical procedure for assessing the system reliability of a rock tunnel. Three failure modes, namely, inadequate support capacity, excessive tunnel convergence, and insufficient rockbolt length, are considered and investigated using a deterministic model of ground-support interaction analysis based on the convergence–confinement

Availability of a System with Multiple Failure Modes and Imperfect Repairs
Economic Quality Control, 2011Summary: This study focuses on modeling the reliability of systems with multiple failure modes and imperfect repairs. Times to failure are exponentially distributed and repair times follow general distributions. Closed expressions are obtained for the steady state availability and Laplace transforms of the point-wise availability.

Availability and maintenance modelling for systems subject to multiple failure modes
Computers & Industrial Engineering, 2017A maintenance model is formulated for a competing-risk system.The analytical results on system availability are derived.The optimal maintenance policy maximizing steady-state availability is obtained.The optimal maintenance policy minimizing long-run average cost rate is derived.

Analysis of a Repairable System Subjected To Multiple Modes of Failure
Economic Quality Control, 2004Summary: Systems deteriorate over time and hence require maintenance. This paper discusses the operational performance of a repairable system subjected to several modes of failure. Unlike many models in the literature, where after each failure the system is perfectly repaired (replaced), it is assumed here that the system performance is declined after ...

Reliability Analysis on Competitive Failure Processes under Multiple Failure Modes
Applied Mechanics and Materials, 2013In this article, a new multiple competing failure models proposed, in which multiple degradation processes and random shocks are considered. The shocks have a significant impact on system reliability, and the system reliability under not considering the impact of shocks is much higher than the impact of shocks is considered. In addition, the influences

Regional importance analysis under multiple failure modes
2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS), 2016For structural system with multiple failure modes extensively present in engineering practice, two regional mode importance measures are proposed on the basis of the existing mode importance measures, i.e., the regional mode importance measure based on failure probability and the regional mode importance measure based on sample mean of output response.

A dependent multiple failure mode modelling procedure
Communications in Statistics - Theory and Methods, 1985Under mild distributional assumptions,Langberg,Proshane,and Quinzi demonstrated the changing of a dependent competing failure mode system into an independent one.In this paper, their procedure is ultiized to construct dependent failure mode models.The common reliablity models, Exponential,Weibull and Extreme value, are examined with this procedure and ...
