摘　　要：网络系统可靠度研究方法主要有概率解析法和随机模拟法.随机模拟法通常被认为收敛速度慢且无法计算系统的单元概率重要度,从而不被主流研究者重视.深入探讨了随机模拟法的特点,理清了一些关于该方法的常见误解,并给出了采用随机模拟法计算网络系统单元概论重要度的有效算法.最后给出算例,证明了随机模拟法的有效性以及在大规模复杂网络上的优越性.There are two methods in network reliability research, probability analysis method and stochastic simulation method Stochastic simulation method is usually seen as slow convergence and cannot compute probability importance of element, so as not to be the mainstream method to researchers. Stochastic simulation method of network reliability analysis is discussed in depth. And some common misconceptions about this method is clarified. And an effective solution to calculate the element probability importance of the network using stochastic simulation is given. Finally, the examples prove the effectiveness of stochastic simulation, as well as in large-scale complex network of superiority.
