Abstract

This paper is devoted to obtain the two-dimensional reliability modeling equivalence factors of n independent and identical components parallel system. Bivariate Weibull model has been used by considering the failure behavior of components. We discuss two-dimensional failure modeling for a system where degradation is due to age and usage. Three different methods are used to improve the given system. The mean times to failures of the original and improved systems are obtained. Numerical studies are presented to compare the different reliability factors obtained.
