Abstract:
In work the distributed measuring-controlling system functioning in time-sharing mode and providing possibility of qualification tests of several satellite-communications earth station simultaneously is considered. The problem of estimation of response of a multi-user distributed measuring-controlling system on requests of operators is formulated. Based on representation of its functioning in the form of queueing system analytical expressions for distribution of a waiting time results of measurement and main parameters of distribution in a general form are defined. Graphically shows the calculated dependence of the expectation and standard deviation of the waiting time on the example of hypotheses about the exponentially distribution and Gamma-distribution of service time of task measure. Directions for further research to address the problem of identification of parameters of the proposed mathematical model is marked. Conclusions about the appropriateness of applying the results of research during the design and operation in terms of provide the required parameters of the reaction system is represented.
