Features of Assessing the Quality of Functioning of Telecommunication Systems in Transport

Abstract

The purpose of the paper is to show the need for assessing the quality of functioning of telecommunication systems in transport. Show that the problem of the quality of functioning of complex systems, which include telecommunications, is closely related to the reliability of both its individual elements and the system as a whole. From the set of existing parameters for assessing reliability, identify those that have a significant impact on the quality of functioning of transport telecommunication systems. Propose a methodology for assessing such parameters. Parameters for assessing the reliability of complex technical systems in relation to telecommunications were analyzed. The main indicators of the quality of the functioning of telecommunication systems are revealed. It is shown that the functioning of the system can be characterized by an indicator of technical efficiency, reflecting the reliability and recoverability, as well as the correctness of information processing, and quantified by the product of the probabilities of the corresponding private events, which can be considered independent. The calculations of the probability that the execution of the task will not be disrupted due to the unreliability of the system, the probability of the task being completed by the system with the failure-free operation of the equipment for a given time, as well as the probability that the system, being serviceable in the initial state with a given probability, will then work without failure for the specified time and will ensure the correct solution (or execution) of the task are presented. An integral indicator of the quality of functioning for transport telecommunication systems has been developed. The classification of the quality indicators of functioning of telecommunication systems from the position of a set of complex technical systems and man-machine complexes is given.KeywordsTelecommunication systemTransportReliability indicatorQualityFunctioningEfficiencyComplex system
