讲座摘要：

      In this talk, we will consider series and parallel systems comprising n components drawn from a heterogeneous population consisting of m different subpopulations. The components within each subpopulation are assumed to be dependent, while the subpopulations are independent of each other. We also assume that the  subpopulations  have different Archimedean copulas for their dependence.  Under this setup, we discuss the series and parallel systems reliability for three different cases, respectively. We use the theory of stochastic orders and majorization to establish the main results, and finally present some numerical examples to illustrate all the results established here.
