【摘要】 本文根据工程实际,在已有修如旧模型和修如新模型基础上,对可修系统建立了一种复合贮存模型,并在该模型下导出了系统在任意时刻的可用度函数解析表达式：关于可用度的估计,以服从威布尔分布的系统为例,基于系统的贮存寿命试验数据,给出威布尔分布的形状参数和尺度参数的矩估计,进而给出系统可用度的点估计。更多还原

【Abstract】 According to the engineering practice and the existing repaired as old model and the repaired as new model,we propose one new composite model and derive its availability function in details.By applying the model to repairable Weibull systems and basing on life testing,the parameter estimation of the Weibull distribution is derived by moment-type estimators on complete sample and the point estimate of the system availability is also calculated.更多还原
