| 摘 要： | 在进行非Markov系统的可靠性仿真时，为获得准确的状态转移时间抽样，提出剩余分布的近似抽样(ASRD)方法，利用多个均匀分布拟合一般形式的剩余分布，通过拟合参数d调整抽样精度和抽样效率。在此基础上，提出基于强制转移(FT)策略的ASRD(FT-ASRD)仿真方法。多个算例结果表明，当5≤d≤10时，FT-ASRD相对于常规仿真方法具有更高的效率，而且仿真结果的相对误差较小。

| Abstract: | In order to sample precisely the state transition time when simulating non-Markovian system,a new sampling method named Approximate Sampling for Residual Distribution(ASRD) method is put forward,in which several uniform distributions are used to approach general residual life distributions. The approach-coefficient d is used to adjust sampling precision and efficiency. Another method named Forced Transitions(FT) based ASRD(FT-ASRD) simulation method is brought forward to simulate high-reliable non-Markovian... |
