The operation of a call center is described in the form of a retrial queuing system. The dependence of its performance indices on the Markovian and two-phase Erlang distributions of calls’ sojourn time in the orbit is considered. An analytical model of an M / M / c / / / E 2 retrial queuing system is developed. An asymptotic analysis of some characteristics of M / M / c / 0 / 2/ / M and M / M / c / 0 / 2 / / E 2 systems is performed. An application is developed for solving M / M / c / 0 / N / / N / / E 2 and M / M / c / 0 / N / / M systems using sparse matrices.
