ABSTRACT: In this paper, probabilistic models for three redundant configurations
have been developed to analyze and compare some reliability characteristics.
Each system is connected to a repairable supporting external device for
operation. Repairable service station is provided for immediate repair of
failed unit. Explicit expressions for mean time to system failure and steady-state
availability for the three configurations are developed. Furthermore, we
compare the three configurations based on their reliability characteristics and
found that configuration II is more reliable and efficient than the remaining
configurations.
