Abstract
In this article, an \(M/\begin{pmatrix} G_1 \\ G_2 \end{pmatrix}/1\) queue with service interruption consisting of a definite repairability is analyzed in the steady-state regime. Here, the server, after completion of a service, is allowed to take in a single vacation under the Bernoulli schedule. For this model, probability generating function (PGF) for queue length distribution at arbitrary and service completion epoch are derived. Laplace Stieltjes Transform (LST) of a busy period distribution and waiting time distribution are obtained. In addition to these, some important performance measures such as the mean queue size and the mean waiting time of a customer are achieved. The reliability indices for this model are carried out and are included in the study. An optimal operation policy of the model in terms of total expected cost is developed at a lower cost. Finally, various numerical examples are presented in support of the theory.
