In this study, it was considered a cold standby system with two dissimilar units for evaluation of its
reliability parameters. These two units are named as priority unit (P-unit) and standby unit (S-unit). The m ain
working unit is P-unit but on failure of this unit we may online S-unit through an imperfect switching device.
This S-unit is not efficient to fulfill the requirements similar to P-unit. In this study, the authors have been used
a random check for S-unit during its non-operation period. Mathematical model of the system has been solved
with the help of Laplace transform. Head-of-line policy has been used for repair purpose. Asymptotic behaviour
of system and some particular cases have been computed to improve practical utility of the model. Reliability
function, availability function and MTTF of considered system have been obtained. At the last, we appended
a numerical illustration together with its graphical representation to highlight important results of this study.
Key words: Asymptotic behaviour, availability function, markovian process, MTTF, reliability function, supplementary variables,
