Stochastic Analysis of aTwo Non-Identical Units Redundant System with Preventive Maintenance and Priority
Vikas Garg , M S Kadyan , Jitender Kumar
Abstract

This paper deals with a two non-identical units (original and duplicate) redundant system  subject to preventive maintenance (PM). Initially, the original unit is operational and duplicate unit is held back as cold standby. Both units undergo for PM after a maximum operation time. Priority in operation and service is given to the original unitover duplicate unit. There is a single server who visits the system immediately as per requirement. The distributions of failure time and maximum operation time of the units follow exponential while that of PM and repair times are taken as arbitrary with different probability density functions. Various reliability measures are obtained in steady state by applying the regenerative point technique. Graphs are also plotted to show the trend of Mean Time to System Failure (MTSF), availability and profit of the system model for a particular case.
