Reliabilitymeasures of a two unit model in cold standby mode with expert repairman

Abstract

In this paper,the profit of a two unit cold standby system have been analysed.We have taken a two unit cold standby system having an expert repairman and his assistance.When a unit failed then standby unit becomes operating unit and his assistance repairman can repair the failed unit after getting the instruction from the expert. When the expert is busy in repairing the failed unit and also at that time standby unit failed then he leave the repair in the suspension and give instruction to his assistance.The profit rate is calculated where the failure follow exponential distributions. Graphs are plotted with the help of data given in terms of reliability parameters such as availability,MTSF,busyperiod,expected no. of repairman visits using regenerative point of graphical technique.
