Interval-valued reliability assessment of 2-out-of-4 system

Abstract

Present paper computes the interval-valued reliability of an engineering system in the context of the value of state performance. In this study, we have evaluated the interval-valued reliability of a 2-out-of-4 system with the help of reliability function. The considered model of 2-out-of-4 system consists of 2 numbers of components connected in series. The interval universal generating function technique has been used to calculate the interval-valued reliability of the proposed model. In this paper, the proposed algorithm is based on interval arithmetic to calculate the reliability of the 2-out-of-4 system. A numerical example illustrates the proposed model.
