ABSTRACT
Due to the flexibility of the hazard rate function of the Lomax-exponential distribution, it provides a good alternative for some existing life distributions in modelling positive real data sets in practice. Recently, heterogeneity of components in a system is an appealing topic in some research studies. In this article, we discuss some stochastic comparisons of series systems with independent heterogeneous Lomax-exponential components in the sense of comparing the parameter vectors and matrices. Finally, some examples are illustrated for some of the proven results.
