Abstract

In this paper the object of investigation is one of the variants of combined strategy of maintenance of cellular network when the one repair team doing planned-preventative maintenance and disaster recovery. To building a mathematical model the maintenance is represented as a queuing system. Graph of states and transitions for the queuing system is developed, and the Kolmogorov – Chapman system of differential equation is formed. Solution of the equations allows to make reliability indexes (function availability, availability factor) and calculate of duration of stay a repair crews in various stages of reconstruction. Dependence of the availability factor of the cellular network on the number of objects in the group, which maintained of one repair team and the periodicity of maintenances of each object are shown.
