This paper examines the problem of stochastic comparisons of series and parallel systems with independent and heterogeneous Log-logistic components. Using concepts of majorizatin, weak supermajorization and p-larger order, we establish usual stocahastic order, hazard rate and reversed hazard rate order between these systems. We also discuss the stochastic comparisons of two vector of order statistics arising from two independent and hetrogeneous Log-logestic samples.
