Cold-standby redundancy allocation problem with degrading components [PDF]

open access: yesInternational Journal of General Systems, 2015
Components in cold-standby state are usually assumed to be as good as new when they are activated. However, even in a standby environment, the components will suffer from performance degradation. This article presents a study of a redundancy allocation problem (RAP) for cold-standby systems with degrading components.

Reliability Importance of Components in a Real-Time Computing System with Standby Redundancy Schemes [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2018
Component importance analysis is to measure the effect on system reliability of component reliabilities, and is used to the system design from the reliability point of view. On the other hand, to guarantee high reliability of real-time computing systems,

Redundancy Allocation of Components with Time-Dependent Failure Rates

open access: yesMathematics, 2023
The Redundancy Allocation Problem (RAP) is well-known in the field of reliability optimization. In this paper, RAP is investigated assuming that the distribution of the time to failure of the components has the form of an Erlang distribution with a time ...
