Initially unit G is in operating state while as unit P and C are in idle state. System failure occurs if either unit G fails when unit P and C are in idle state or G and P fails when C is in idle state or when all the units’ viz. G, P and C fails totally. Single repair facility is available to repair the failed unit in which unit G gets priority for repair over P and C and then if unit P and C fails, second priority is given to unit P over C and finally unit C is repaired by repairman till the system becomes operative. Once the repairman starts repair of the failed unit, he does not leave the system till all units are repaired during his stay in the system as per priority. The failure time distributions of unit-G, P and C are taken exponential. The distribution of time to repair of unit-G, P and C is assumed to be general. After repair a unit becomes as good as new.

INTRODUCTION Reliable functioning of embedded systems is of paramount concern to the billions of users that depend on these systems every day. Unfortunately most embedded systems still fall short of user's expectation of reliability. The incorporation of redundancy is one of the important techniques to improve the reliability and hence the effectiveness of the system. The system models with standby redundancies have been frequently analysed by various authors with different assumptions due to their vital existence in modern industries and business. Gupta, Tyagi and Kishan [6] discussed the concept of a two unit system with correlated failures and repairs and random appearance and disappearance of repairman. Kishan and Jain [8] analysed a two non-identical unit standby system model with repair, inspection and post-repair under classical and Bayesian viewpoints. Agnihotri and Satsangi [1] considered two unit identical systems with priority based repair and inspection. While Tuteja and Malik [9] discussed about reliability and profit analysis of two single unit models with three modes and different repair policies of repairman who appears and disappears randomly. Goel, Sharma and Gupta [2] worked on cost analysis of a system with intermittent repair and inspection under abnormal weather. Further Joorel, Kumar and Lal [3] put forth the concept of Reliability analysis of a complex system composed of two parallel subsystems without considering random appearance and disappearance of repairman in the system. Gupta, Goel and Tomer [7] provided the concept of analysis of a two unit standby system with correlated failure and repair and random appearance and disappearance of repairman. Nakagawa and Osaki [5] investigated stochastic behavior of two unit priority standby redundant system with repair. Recently Kakkar, Chitkara and Kumar [4] discussed reliability analysis of a cold standby system with repair equipment failure and appearance and disappearance of repairman with correlated lifetime. The purpose of the present paper is to put forth the concept of random appearance and disappearance of repairman in the system. The system comprises of two non-identical units A and B, each unit having two modes Normal and Failure in which unit A is operative and unit B is kept in standby mode. Upon failure of operative unit, unit B

Initially system is in operative state with controlled demand factor i.e. when demand is less or equal to production then it may transit to the state with uncontrolled demand factor i.e. when demand is greater than production. The system remains in upstate with demand factor controlled and uncontrolled while in down state on failure of the unit. On failure of the system, an inspection is carried to detect the type of failure. There are three types of failures, i.e. failure due to poor design of component, improper selection of material and human error. Single repair facility is available to repair the system. The failure time distributions of the unit are taken as exponential and inspection time of the unit is also taken as exponential. The distribution of time to repair of unit is assumed to be general. The various important measures of system effectiveness have been obtained and studied.

A... more PurposeOne of the common approaches to improve systems reliability is using standby redundancy. Although many works are available in the literature on the applications of standby redundancy, the system components are assumed to be independent of each other. But, in reality, the system components can be dependent on one another, causing the failure of each component to affect the failure rate of the remaining active components. In this paper, a standby two-unit system is considered, assuming a dependency between the switch and its associated active component.Design/methodology/approachThis paper assumes that the failures between the switch and its associated active component follow the Marshall–Olkin exponential bivariate exponential distribution. Then, the reliability analysis of the system is done using the continuous-time Markov chain method.FindingsThe derived equations application to determine the system steady-state availability, system reliability and sensitivity analysis on t...

Weed free treatment recorded numerically highest crop growth rate (CGR) and net assimilation rate (NAR) of mustard at all the stages of observation. As regards yield, sole stand recorded significantly higher values of grain and was followed by addit...

Although many works are available in the literature on the applications of standby redundancy, the system components are assumed to be independent of each other. But, in reality, the system components can be dependent on one another, causing the failure of each component to affect the failure rate of the remaining active components. In this paper, a standby two-unit system is considered, assuming a dependency between the switch and its associated active component.Design/methodology/approachThis paper assumes that the failures between the switch and its associated active component follow the Marshall–Olkin exponential bivariate exponential distribution. Then, the reliability analysis of the system is done using the continuous-time Markov chain method.FindingsThe derived equations application to determine the system steady-state availability, system reliability and sensitivity analysis on t...
