Synchronous operation of standby units with provision of maintenance facility

The aim of this paper is to analyze the system consisting of one main unit and three cold standby units. The system is provided with maintenance facility under the constraint of synchronous operation of all the cold standby units. This provision of maintenance has a significant role in order to improve the reliability of the whole system. There is a single repairman available for both purposes: repair as well as maintenance. System effectiveness measures such as behavior of Mean time to system failure (MTSF), Availability, Busy period and Cost benefit analysis has been done for the present study using Semi-markov process and Regenerative point technique. Graphical interpretation has also been performed considering particular cases.
