Abstract

The present paper is an attempt to study a two-unit (original and duplicate) redundant system with preventive maintenance and priority in operation. Initially the original unit is operative and duplicate unit is held back as cold standby. Both units undergo for preventive maintenance after a maximum operation time. Priority is given to the original unit in operation. There is a single server who visits the system immediately as per demand. The random variables associated with failure time, preventive maintenance time and repair time are statistically independent. The distributions of failure time and maximum operation time of the units follow exponential while that of preventive maintenance and repair times are taken as arbitrary with different probability density functions. Various reliability measures are obtained in steady state by using the regenerative point technique. Graphs are also plotted to depict the behavior of Mean Time to System Failure (MTSF), availability and profit of the system model for a particular case.
