This paper studies the usual stochastic, star and convex transform orders of both series and parallel systems comprised of heterogeneous (and dependent) components. Sufficient conditions are established for the star ordering between the lifetimes of series and parallel systems consisting of dependent
components having multiple-outlier lomax model.
We also prove that, without any restriction on the parameters, the lifetime of a parallel or series systems
with dependent heterogeneous components is smaller than that with dependent
homogeneous components in the sense of the convex transform order.
