Abstract:

Because  of the  drawbacks of current researches when dealing with the problems of  evaluating the reliability of a  complex system containing components with propagated failures,a  cellular  automata-based  Monte  Carlo  simulation algorithm was presented to  deal  with the complex problems,which combined  the  advantages of  parallel computing  of cellular automata and the flexibility of Monte Carlo simulation technology.The proposed algorithm considered the influences  of imperfect protections on system reliability and overcame the limitations of system structure and the number of components. Finally, two given examples illustrated the validity of the proposed algorithm  respectively  and
the method to analyze system reliability.

Key words: complex system;propagated , failure;imperfect , protection;cellular , automata;Monte Carlo , simulation

摘要:

鉴于已有研究在处理由部件失效传播引起的共因失效的复杂系统可靠性评估问题时存在的缺陷,借鉴元胞自动机并行计算的优势以及蒙特卡罗模拟技术在处理复杂问题中的灵活性,提出了一种基于元胞自动机思想的蒙特卡罗模拟方法,该方法考虑了不完全保护对系统可靠性产生的影响,不受系统结构、部件数目的限制。最后,通过两个算例分别说明了该方法的正确性以及在可靠性分析中的具体应用。
