Abstract: 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 example is given to illustrate these results obtained in the paper.

Key words: reliability, availability, supplementary variable, Laplace transform
