AB  - This study deals with some characteristics of a single-unit of a man-machine system operating
under different physical conditions. The failure, repair and change of physical conditions (good-poor) are
stochastically independent random variables each having an arbitrary distribution. The system analysed by
some Markov process technique. The busy period, expected number of visits by the repairman and the cost
per unit time in a steady state of the system are obtained. Several important results have been derived as
particular cases.
