Abstract: In this article, we examine a single-server queueing model in which customers arrive at one of three different rates depending on the system's current state as determined by a Markovian arrival process. After obtaining the server's essential service, customers have the option of pursuing the second optional service. The service time is distributed in a phase-type manner. If the main server successfully completes an essential repair, the server may choose an optional repair option or return to the service station. We examined the total number of customers existing in the system using the matrix-analytic method (MAM) under the steady-state probability vector. We analyse the features of system performance measures. We discussed the stability condition, the analysis of the busy period, and the distribution of waiting times. For a better understanding of our suggested model, numerical results and graphical representations are provided.
