“…Malik [1] studied some stochastic models with priority to operation over repair with arrival time of the server and derived several measures of reliability for the system. Malik et al [2] derived the expressions for economic analysis of repairable systems by using the concept of random appearance and disappearance of the server.…”

The main objective of present work is to carry out various important reliability measures of a two-unit cold standby repairable system with priority to operation over preventive maintenance by using regenerative points technique and semi-Markov process. A single repair facility is provided to conduct repair and maintenance of the system as and when required. All times distributions are exponential except the repair and preventive maintenance time distributions which are considered as general.

“…Damcese and Temraz (2010), Goel and Gupta (1984) have studied the analysis of two unit parallel system. El-said (2008), El-said and El-sherbeny (2005), Gopalan and Nagawalia (1985), and Rander (1994) have studied the cost analysis with preventive maintenance of different system. El-said and Elsherbeny (2005) by using linear first order differential equation evaluated the reliability and availability characteristics of two different systems.…”

Reliability is an important area that is receiving attention globally. This paper studies reliability analysis of a two-dissimilar-unit cold standby system with three modes using Kolmogorov forward equation's method, in which its reliability and availability analysis are evaluated. This proposed system has been investigated under three modes: normal, partial failure, total failure. The failure and the repair time are assumed to have exponential distribution. The effect of failure rate on meantime to system failure ( MTSF ), steady state availability ( ( ) T A  ) and the profit function ( ) PF  of the system are compared. It was found that MTSF ,( ) PF  are decreasing with the increase of the failure rate.

“…Two-unit standby systems have been discussed by various researchers including (Tuteja et al, 2001a;2001b;Goyal et al, 2009;Gopalan and Nagarwall, 1985;Tuteja and Taneja, 1992;Khaled and Mohammed, 2005) in the field of reliability under various assumptions/considerations. Most of these studies are not based on the real data.…”

Problem statement:The study deals with a standby system consisting of two units. Initially one unit is operative and the other is standby. When both the units are failed then there is a provision of switching over to the other similar system. This practical situation may be observed in an oil refinery plant. Real data on failure and repair rates of such units collected from oil refinery plant, Pani pat, India have been used for present study. Approach: The system is analyzed by making use of semi-Markov processes and regenerative point technique. Results: Expression for the expected profit is obtained after obtaining various measures of system effectiveness. Graphical analysis is also done for a particular case and various interpretations are made. Conclusion: Upper/lower limits for various rates/costs/probabilities can be obtained to get the positive profit for the system and to decide about the least value of the price of the product to be produced.
