Abstract

In the present paper we analyse a two dissimilar unit cold standby system in which both units are switched their places (as operative and standby modes) after a random amount of time. The random amounts of time for both units are to be decided by the experts from the past data of both types of units, which gives the option to enhance the reliability of the system as a whole. For switching of units after failure we use a device, which have some fixed known probability of failing at a time of switching. It is also assumed that the random variables denoting failure and repair times are correlated having their joint density as bivariate exponential.
