摘　　要：最近,KUO和KE[Reliability Engineering and System Safety. 2016,145:74-82,参考文献[11]在假定部件故障后的修理时间以及修理设备故障后的修理时间均为一般分布的情形下,运用补充变量技术分别推导出三种可修系统模型的稳态可用度。然而作者并没有研究系统的瞬时可用度,本文在文献[11]的基础上,运用补充变量法推导出文献[11]中模型一的瞬时可用度的表达式。最后,用一个数值算例对所得结果进行了模拟实现。Recently, KUO and KE [Reliability Engineering and System Safety. 2016, 145 ： 74-82, see reference [11] assume that the repair time of the failure component and that of the failure server are general distribution, and the steady state availability of the three repairable systems are obtained by using supplementary variable method respectively. However, the instantaneous availability is not investigated in reference[11]. In this paper, the instantaneous availability of the model 1 is obtained by using supplementary variable method. Finally, a numerical examole is given to illustrate, these results obtained in the paper.
