There are two effective ways to maintain the system to perform a high or required level of reliability and availability: one is spare units for key units; the other is several maintainers for the system. To solve reliability indexes of complex mechanical system under these assumptions, a system model was established, which consists of two dissimilar subsystems in series and each subsystem is wa...

In this paper we analyze the dynamic behavior of a two unit parallel system with warm standby and common-cause failure. By the semigroup theory of linear operators on the Banach space, we give the wellposedness of the system and then prove the existence of the nonnegative dynamic solution and the steady solution of system. By spectral analysis of the system operator, we show that all the spectr...

In a server power system, a standby converter is required in order to provide the standby output, monitor the system’s status, and communicate with the server power system. Since these functions are always required, losses from the standby converter are produced even though the system operates in normal mode. For these reasons, the losses deteriorate the total efficiency of the system. In this ...

<p style='text-indent:20px;'>Redundancy allocation problem (RAP) is a common technique for increasing the reliability of systems. In this paper, new model RAP introduced that takes into account warm standby and mixed strategy, dynamics, type strategy in redundancy problems. A recursive formula first obtained function dynamic strategies leverages success mode analysis works any arbitrary f...

Many authors have studied repairable redundant system operating in different condition under the assumption that the system received corrective maintenance at failure and preventive maintenance before failure. However, little or no attention is paid on whether the system can receive minor and major maintenance when it is operating in a reduced capacity state. In this study we consider a redunda...

This paper presents reliability and availability analysis of a k-out-of-(M+S): G warm standby system with time varying failure and repair rates in presence of commoncause failure. The system composed of two categories of components. One category of the components is of type 1 has M components and the other is of type 2 has S components. Type 1 have a lower failure rate. Markov method is used to...
