Abstract
In this paper Availability Modeling of Two Unit Warm Standby System Having Imperfect Switch-Over Device using RPGT is discussed. Initially the main unit is working at full capacity which may have two types of failures, one is direct and the second one is through partial failure mode. Second unit have warm standby unit switched in by a switch-over device which may not be perfect .There is a single server (repairman) who inspects and repairs the unit on each failure. Fuzzy concept is used to determine failure/working state of a unit. Taking failure rates exponential, repair rates general and taking into consideration various probabilities, a transition diagram of the system is developed to determine Primary circuits, Secondary circuits & Tertiary circuits and Base state. Problem is formulated and solved using RPGT to determine system parameters i.e. Mean Time to System Failure, Busy period of the Server, Expected No. of Server’s Visits. Particular cases are taken for warm, hot and cold standby cases. System parameters have been discussed with the help of graphs and tables.
