Investigation of the effect of maintenance strategy parameters on the accident rate of the mobile communication system

The article presents the results of the study of the influence of monitoring and diagnostic means on the values of reliability and functional safety indicators of fault-tolerant information transmission systems. The study was carried out by modeling several variants of a fault-tolerant information transmission system. As a modeling method, an improved state transition diagram with automated construction of a graph of states and transitions is used. On the basis of the obtained results, recommendations for the selection of reliability indicators of control and diagnostic means are formulated to ensure a minimum reduction in the reliability of a fault-tolerant information transmission system.
