Optimal redundancies for reliability and availability of series systems
TL;DR: In this paper, five different series system configurations with standby units are compared based on their overall reliability and availability, where the time-to-failure of a component and its repair time are assumed to have the negative exponential distribution.

Stochastic Analysis of a Two-Unit Cold Standby System Wherein Both Units May Become Operative Depending upon the Demand
Reetu Malhotra,Gulshan Taneja +1 more
TL;DR: In this article, a two-unit cold standby system is proposed, where one unit is operative while the other is kept as cold standby, and if the operative unit fails or the demand increases to the extent that one operative unit is not capable of meeting the demand, the standby unit becomes operative instantaneously.

Reliability analysis of a complex system with a deteriorating standby unit under common-cause failure and critical human error
S. Narmada,Mendus Jacob +1 more
TL;DR: In this paper, a stochastic model representing two units and one as a standby unit with critical human error and common cause failure is presented, and the deteriorating effect of the standby unit on the system is studied.
Journal ArticleDOI
Study of reliability measures of a local area network via copula linguistics approach
TL;DR: In this article, the reliability measures of Linux operating system connected in local area network (LAN) have been found by using supplementary variable technique and Laplace transformation, by taking different types of failure and two types of repairs the availability, non-availability, mean time to failure and cost analysis (expected profit) of the design system have been obtained.
Journal ArticleDOI
Analysis of a two unit deteriorating standby system with repair
TL;DR: In this article, the reliability analysis of a two unit standby system with repairs for common cause failure and critical human error is studied, and various measures of system effectiveness such as pointwise availability, steady-state availability, MTTF and variance of the time to failure of the system are obtained.

Common mode failure analysis
TL;DR: In this article, the authors summarize the state of the art as reliability engineers seek to extend the reliability analysis techniques to include multiple failures from a common cause (or in a common mode).

Stochastic analysis of standby systems with common-cause failures and human errors
Balbir S. Dhillon,Nianfu Yang +1 more
TL;DR: Two newly developed Markov models representing two identical unit standby systems with common-cause failures and human errors are presented, and the system reliability, mean time to failure, variance of time to fail, and time-dependent system availability expressions are developed.

Stochastic modelling of k-out-of-n units family of systems
TL;DR: In this article, two newly developed stochastic models to perform reliability and availability analyses of (n − 1)-out-of-n units and systems with common-cause failures and critical human errors are presented.

MTTF and availability evaluation of a two-unit, two-state, parallel redundant complex system with constant human failure
P.P. Gupta,Arvind Kumar +1 more
TL;DR: To make the system more compatible with the physical situation, MTTF for the system has been evaluated and various graphs have been plotted to highlight the utility of the model.
