【摘要】：为了研究不同类型元件组成系统后元件各自的维修率,同时考虑工作环境因素对维修率的影响,提出了元件维修率分布的概念。元件维修率分布是通过将SFT中故障概率分布代替Markov链中失效率实现的,给出了不同元件组成的并联和串联系统的元件维修率分布推导过程。实现维修率分布的计算关键在于状态转移概率p_0范围的确定及不同元件故障率与维修率的比值,即为计算过程所需的限制条件,给出了p_0范围和比例限定的计算方法和依据。对一个混联系统进行分析,说明了p0范围依赖于系统结构并计算得到0.087≤p_0≤0.625,也得到了系统中三个不同元件的维修率分布。
[Abstract]:In order to study the maintenance rate of different components in the system and consider the influence of working environment on the maintenance rate, the concept of component maintenance rate distribution is put forward. The component maintenance rate distribution is realized by replacing the failure rate in the Markov chain with the fault probability distribution in SFT. The derivation process of component maintenance rate distribution for parallel and series systems with different components is given. The key to realize the distribution of maintenance rate lies in the determination of the range of state transition probability and the ratio of failure rate to maintenance rate of different components, that is, the calculation method and basis for the limitation of the range and proportion of pStue 0 for the calculation process. An analysis of a hybrid system shows that the range of p0 depends on the structure of the system and calculates that 0.087 鈮，
