Abstract: | The author concerned the reliability evaluation as well as queueing analysis of
retrial queues with two different types of primary customers arriving according to independent Poisson flows. In the case
of blocking, the first type of customers can be queued whereas the second type of customers must leave the service area but
return after some random period of time to try their luck again. The author assumes that the server is unreliable and it has
a service-type dependent, exponentially distributed life time as well as a service-type dependent, generally distributed repair
time. The necessary and sufficient condition for the system to be stable is investigated. Using a supplementary variable method,
the author obtains a steady-state solution for queueing measures, and the transient as well as the steady-state solutions
for reliability measures of interest.
