Availability modeling two units system subject to degradation post repair after complete failure using RPGT
In this paper, availability modeling and analysis of two units system out of which one unit undergoing degradation after complete failure using Regenerative Point Graphical Technique (RPGT) is discussed. Initially both units are working at full capacity out of which one unit may have two types of failures, one is direct and second one is through partial failure mode. There is a single server (repairman), who inspects and repairs the units on each failure. On each repair unit under goes degradation if the server reports that unit is not repairable then it is replaced by a new one, which follows a general distribution other unit have perfect repair. On complete failure the unit cannot be restored to its original capacity. 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 find Primary circuits, Secondary circuits & Tertiary circuits and Base state. Problem is solved using RPGT to determine system parameters. System behavior is discussed with the help of graphs and tables.
