Abstract

In this paper, we investigate a single-server Poisson input queueing model, wherein arrivals of units are in bulk. The
arrival rate of the units is state dependent, and service time is arbitrary distributed. It is also assumed that the
system is subject to breakdown, and the failed server immediately joins the repair facility which takes constant
duration to repair the server. By using supplementary variable technique, we obtain the probability generating
function of the number of units in the system which is further used to establish some performance indices such as
the mean number of units in the system, mean waiting time, etc. Special cases are also discussed. In order to
obtain approximate values of system state probabilities, the principle of maximum entropy is employed. Numerical
results are also presented to validate the analytical formulae.
