Lizgin V. Identification of input stream parameters requests on looking for work of functioning devices

The thesis is devoted to queuing systems M/G/1/0 with supplanting demands. The first four ordinary moments for these intervals are founded for mentioned system and system M/M/. Estimates of the system loading, intensity of input demands stream and mean service time are developed. The first four ordinary moments for time intervals of the in-process work under some threshold are founded for system M/M/ when not completed work decrease linear. Estimates of parameters of system are developed regarding the observation of the meet moments of the process of not completed work and the threshold, and the asymptotic variances covariance of estimates are founded. Transition and bounding probabilities, average of distribution of the time intervals between events of the observed input demands stream have been found for system M/M/n/0. The estimate of the loading of system according to the method of moments is suggested on the basis of this analyze.
