On Likelihood Ratio Ordering of Parallel Systems with Two Generalized Exponential Components
Abedin Haidari , Mostafa Sattari * , Ghobad Barmalzan
Abstract:   (955 Views)

Consider two parallel systems with their component lifetimes following a generalized exponential distribution. In this paper, we introduce a region based on existing shape and scale parameters included in the distribution of one of the systems. If another parallel system's vector of scale parameters lies in that region, then the likelihood ratio ordering between the two systems holds. An extension of this result to the case when the lifetimes of components follow exponentiated Weibull distribution is also presented. 

Keywords: Parallel Systems, Likelihood Ratio Order, Generalized Exponential Distribution, Exponentiated Weibull Distribution.
