| 摘 要： | 国内外关于动态冗余结构系统可靠性分析问题的主要方法是马尔科夫模型,然而,对于二乘二取二的相对复杂的冗余系统,使用马尔科夫模型进行分析时,其状态空间的规模与双机热备系统相比具有较大增长,致使其建模过程及求解过程十分繁琐.本文旨在使用动态故障树方法对二乘二取二系统的可靠性分析进行建模与求解,同时通过可靠性和安全性曲线,与双... |

| Abstract: | The main method to analyze reliability and safety of the dynamic redundancy structure at home and abroad is the Markov model.However,when using the Markov model to analyze the relatively complex redundant system,i.e.,the double 2-vote-2 computer-based interlocking system,the scope of the state space of the double 2-vote-2 system exhibits great growth as compared to the quantum hot standby system.This causes the modeling process and solving procedure to become complex and miscella neous.This paper is for the... |
| Keywords: | double 2-vote-2 system methods of dynamic fault tree Markov model BDD |
