Availability and reliability of a 2-unit 2-server system subject to preventive maintenance and repair

چکیده
— This paper deals with the availabiïity and reliability analysis of a 2-unit System with two service facilities-one for préventive maintenance and the other for repair. The times to failure and préventive maintenance of a unit are assumed to be arbitrariîy distributed whüe the times for repair and préventive maintenance are exponentially distributed. The Laplace transforms ofthe mean down-time of the system during (0, t) and the mean time to system failure are obtained explicitly. An expiicit expression for the steady-state availabiïity of system is also obtained. The case when the distribution of the time to failure is erlangian and that ofthe time to préventive maintenance is exponential is discussed.

Modeling and Availability Analysis of Internet Data Center with various Maintenance Policies
In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...
متن کاملAn Optimal Preventive Maintenance Model to Enhance Availability and Reliability of Flexible Manufacturing Systems
General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...
متن کاملFault tolerant system with imperfect coverage, reboot and server vacation
This study is concerned with the performance modeling of a fault tolerant system consisting of operating units supported by a combination of warm and cold spares. The on-line as well as warm standby units are subject to failures and are send for the repair to a repair facility having single repairman which is prone to failure. If the failed unit is not detected, the system enters into an unsafe...
متن کاملA Parallel System with Priority to Preventive Maintenance over Repair Subject to Maximum Operation and Repair Times
Abstract In this work, a stress is given on the evaluation of performance measures of a parallel system under priority with necessary conditions on operation and repair times. The units are identical in nature subject to constant failure. There is a single server who visits the system immediately to rectify the faults whenever occurred in the system. The system undergoes for preventive maintena...
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...
