摘要
根据已知的基于最小路径或最小割集复杂系统可靠度函数的解析表达式,给出当子系统寿命分布服从指数分布时,系统平均寿命的表达式.利用这一表达形式,在子系统寿命变量服从指数分布条件下,分别就完全数据和截尾数据两种情况,给出了系统平均寿命的估计,并对估计性质进行了研究.并在完全数据下,给出了估计的渐近分布.
Given the mean life of the complex system when the subsystem life has exponential distribution,according to the known analytical expression of the reliability function based on the minimum path or minimum cutset for the class of complex system.By using this expression,estimation of the system mean life are presented under complete datum as well as censored datum,we study the properties of the estimate when the subsystem life has exponential distribution.Furthermore,we prove the asymptotic normality of complex system reliability under complete datum condition.
