چکیده
In this paper we study the economic and performance evaluation of two non identical unit cold standby systems with hardware failure and human error. After pre specific time known as Maximum operation time (MOT) the system undergoes for PM from operative state. The failure and repair rate times follow exponential distribution. There is a single server who visits the system immediately whenever needed to carry out preventive maintenance and repair the unit works as good as new after preventive maintenance and repair Using semi Markov process and regenerative point techniques expression for various reliability characteristics are obtained and expected profit is calculated. At the last the results are discussed with the help of numerical values.

Performance Analysis of a Repairable Robot Safety System with Standby, Imperfect Coverage and Reboot Delay
The present study deals with a robot safety system composed of standby robot units and inbuilt safety unit. When the main operative unit fails, it is replaced by the standby robot unit available in the system. The concept of reboot delay is also incorporated in this study according to which the robot unit is rebooted if it is not successfully recovered. The recovery and reboot times of failed u...
متن کاملStochastic Modeling of a System with Priority for Operation to New Unit and Preventive Maintenance at Pfs Subject to Mot
A stochastic model for a cold standby system of two identical units is developed in which unit fails completely either directly from normal mode or via partial failure. The unit undergoes preventive maintenance (PM) after a maximum operation time (MOT) at its partial failure stage (PFS). There is a single server who visits the system immediately as and when needed to do preventive maintenance a...
متن کاملCold standby redundancy optimization for nonrepairable series-parallel systems: Erlang time to failure distribution
In modeling a cold standby redundancy allocation problem (RAP) with imperfect switching mechanism, deriving a closed form version of a system reliability is too difficult. A convenient lower bound on system reliability is proposed and this approximation is widely used as a part of objective function for a system reliability maximization problem in the literature. Considering this lower bound do...

متن کاملReliability Analysis of Redundant Repairable System with Degraded Failure
This investigation deals with the transient analysis of the machine repair system consisting of M-operating units operating under the care of single repairman. To improve the system reliability/availability, Y warm standby and S cold standby units are provided to replace the failed units. In case when all spares are being used, the failure of units occurs in degraded fashion. In such situation ...
