Stochastic analysis of a complex repairable system comprises two subsystems in series configuration via multi-repair strategy

The present paper study of the complex repairable system in combination with subsystems in series configuration each having four identical units and work policy as; the 2-out-of-4: G scheme. The entire system embraces exponential failure rates and variable repair rates. The system performance was evaluated employing a supplementary variable approach for different types of failure and two types of repairs under the concept of joint probability distribution Gumbel-Hougaard family copula. The traditional reliability measures have been computed with the implication of Maple 17 software. Tables and Graphs predict the behavior of the system for different values of the time variable. © 2022, The Author(s), under exclusive licence to Society for Reliability and Safety (SRESA).
