【 摘 要 】

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