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 ...

This paper deals with the transient analysis of K-out-of-N: G system consisting of Noperatingmachines. To improve system reliability, Y cold standby and S warm standbys spares areprovided to replace the failed machines. The machines are assumed to fail in multiple modes. At leastK-out-of-N machines for smooth functioning of the system. Reliability and mean time to failure areestablished in term...

Pumping systems are an integral part of water desalination plants, their effective functioning is vital for the operation of a plant. In this research work, the reliability and availability of pressurized pumps in a reverse osmosis desalination plant are studied with the objective of finding configurations that provides optimal performance. Six configurations of a series system with different n...

Functionality for efficient computation of properties of system lifetimes was developed, based on the Mathematica framework. The model of these systems consists of a system structure and the component’s independent lifetime distributions. The components are assumed to be non-repairable. In this work a very general implementation was created, allowing a large number of lifetime distributions fro...

This paper deals with a maintainability analysis of a system which consists of three subsystems. Two subsystems in the system are the same and constitute a warm standby redundant system. This warm stand by redundant system and the residual subsystem are connected in series. In this paper, two repair disciplines are considered. One is a priority repair discipline and the other is a non priority ...

Abstract: In this paper, the spectrum of a parallel repairable system with warm standby is investigated. Firstly, we formulate the problem into a suitable Banach space. Then we carry out a detailed spectral analysis of the system operator. Based on the spectral analysis and C0 semigroup theory, we prove the existence of positive solution and finite expansion of the solution corresponding to its...

We deal with three availability systems with warm standby components, fault detection delay and general repair times. Failure times and repair times of failed components are exponentially and generally distributed, respectively. Detection delay times are also exponentially distributed. A recursive method is used to develop steady-state availability, ( Av ), for three systems. We present extensi...
