Praveen Kumar Poonia . Performance Assessment of a Multi-state Standby Series System using Copula Distribution and Catastrophic Failure. International Journal of Computer Applications. 184, 39 ( Dec 2022), 1-7. DOI=10.5120/ijca2022922478
In this paper, the authors study the reliability measures of a complex engineering system consisting of three subsystems namely 1, 2 and 3 in series configuration. The subsystem-1 has three units working under 1-out-of-3: G; policy, the subsystem-2 has two units working under 1-ot-of-2: G policy and the subsystem-3 has one unit working under 1-out-of-1: G; policy. Moreover, the system may face catastrophic failure at any time t. The failure rates of units of all the subsystems are constant and assumed to follow exponential distribution, but their repair supports two types of distribution namely general distribution and Gumbel-Hougaard family copula distribution. The system is analyzed by using the supplementary variable technique, Laplace transformation and Gumbel-Hougaard family of copula to derive differential equations and obtain important reliability characteristics such as availability of the system, reliability of the system and profit analysis. It gives a new aspect to scientific community to adopt multi-dimension repair in form of copula. Furthermore, the results of the model are beneficial for system engineers and designers, reliability and maintenance managers.
