Abstract：The system reliability modeling was studied, considering the correlation between two s-dependent competing failure processes including degradation and shock when system subject to -shock. On the one hand, shock process causes the additional abrupt degradation; on the other hand the degradation of the system impacts the result of the shock process. Assume that the system is subject to -shock process, based on the distribution functions of the system natural degradation process and the shock process, the system's reliability function is derived. The general form of the system's reliability model is presented and one of specific form is given. Finally the simulation is preformed using parameters in the literature. And simulation results show the correctness and validity of the models.
