While modeling stochastic systems it is very important to examine results using reliable statistics analysis. Estimation methods that can allow user to make conclusions about statistical model from simulation results are necessary. These methods are also used while determining relation between simulation time (iterations count) and precision of estimations.

To complete the task regeneration method was chosen. This method is successfully used in various practical problems solving. The usage of regeneration method is based on the fact that many stochastic systems renovate in a probability sense.

Received results are confidential intervals of the N – channel system characteristics (average usage of channels, average queue size, average waiting time in the queue and maximal length of the queue). From these results we can judge about effectiveness of system work and relation between results’ precision and simulation time (iterations count).
