In this paper, the transient solution of a Markovian queuing system with two heterogeneous servers and retention of reneging customers is obtained. The explicit transient probabilities of system size are obtained using probability generating function technique. The corresponding steady-state probabilities are also derived. Further, the time-dependent mean and variance are obtained. Finally, a numerical example is provided to study the behavior of the system. The numerical results show that the heterogeneous system performs better than its homogeneous counterpart.
