The Effect of an age replacement to a standby redundant system

Journal of Applied Probability, 1969
SummaryA multiple unit standby redundant system with preventive maintenance is presented. The Laplace transform of the probability density function of the time to the first emptiness for the system and its mean time are derived. As a special case, a two-unit standby redundant system with preventive maintenance is investigated in detail.

Multiple-Unit Standby Redundant Repairable System

IEEE Transactions on Reliability, 1981
Two models of n-unit standby redundant repairable systems are considered. Identifying suitable regeneration points, expressions for the Laplace transform of the following are obtained: availability; reliability; interval reliability; and s-expected number of visits to any state, repair completions, failures, system downs, system recoveries, and s ...

A Two Unit Standby Redundant System with Standby Failure and Repair Waiting Time

Mathematische Operationsforschung und Statistik, 1973
This paper considers the first time of failure of a 2 units standby redundant system which has a repair waiting time. Five mutually exclusive and exhaustive cases arise, and solutions to these are given together with the mean time to failure. The particular case in which all distributions concerned are exponential is considered, and the steady state ...

Standby redundant systems: a quantitative reliability perspective

International Journal of Reliability and Safety, 2014
To properly design standby systems, adequate techniques and tools allowing quantitative evaluation of the underlying phenomena are required. In particular, different aspects and perspectives have to be considered, overcoming the lacks in the current literature.

A Standby Redundant Complex System with Imperfect Switch

IEEE Transactions on Reliability, 1978
The behaviour is analyzed for a complex system consisting of two units and an imperfect switch. In one unit the components are connected in series while in the other they are in standby redundancy with imperfect switching. Laplace transforms of various state probabilities have been calculated.

Reliability of Several Standby-Priority-Redundant Systems

IEEE Transactions on Reliability, 1977
This paper develops 3 models for standby redundant systems consisting of dissimilar units. In an effort to increase system reliability, priorities are assigned to operating the units as well as for repair in one repair facility. A 1-out-of-3:G system is considered in models 1 and 2.

Reliability prediction of a two-unit standby redundant system with standby failure

Microelectronics Reliability, 1972
Abstract In this paper, the distribution of the first time to system failure (FTSF) and the mean time to system failure (MTSF) of a standby redundant complex system has been evaluated by using the Laplace-Stieltjes transform. It has been assumed that the switching is instantaneous and after repair a unit recovers its function perfectly.

Maintenance of Redundant System with Warm Standby

IEEE Transactions on Reliability, 1981
A 2-unit warm-standby redundant system with repair and preventive maintenance is analyzed. The Laplace-Stieltjes transform of the distribution of the time to first system failure, and its mean, are derived. Preventive maintenance improves the mean time to first system failure.

Insight into Standby Redundancy via Unreliability

IEEE Transactions on Reliability, 1974
Standby redundancy is the oldest form of redundancy using switches. After a failure of the working element, an identical spare is substituted by switching. Unfortunately, the Coverage (the probability of a successful reconfiguration) of the system is always less than unity and, furthermore, the spare element might fail before it is switched in.

The Reliability of Dependent Parallel or Standby N-Unit Redundancies

Operations Research, 1968
This paper is concerned with evaluating the reliability of a redundant configuration, given that at any random time its surviving components are operating with failure distributions that are dependent upon the set of failed components. An expression (9) is derived for the reliability of this class of configurations and is then generalized to obtain an
