The output flow in $H_k/H_k/n/R\leqslant\infty$ queueing systems

The method for calculation the Laplace transform of a $H_k/H_k/n/R\leqslant\infty$ queueing systems output flow distribution is proposed. An expression is provided for the transition from the stationary distribution of the queueing system microstate probabilities at an arbitrary time to the one at the times of service completion. An approach is proposed to calculation of the desired distribution of initial moments, the results of computer experiments are discussed.
