The paper presents reliability and profit evaluation of compressor standby system comprising of two units.Initially one unit is operative and the other is in standby state. On failure of any one of the compressor unit, the standby unit becomes operative to keep the system in operating state. If both the compressor units get failed then system goes to down state. Here compressor unit can fail due to three types of failure which are serviceable, repairable and replaceable type. Out of two compressor units, the unit which fail earlier will get facility of service, repair or replacement. System is analyzed and expressions for various reliability measures such as MTSF, Availability, Busy periods for varioustypes of failures and profit etc have been computed numerically by using semi-Markov process and regenerative point technique Graphs for profit are plotted for making the present study more useful.
