Verification of Mathematical Models for Forecasting Dependability Indicators of Recoverable and Non-recoverable Telecommunication Systems

This thesis examines and analyzes mathematical models for assessing the reliability of telecommunication systems. The main focus is on both recoverable and non-recoverable systems, with an emphasis on various backup methods.[1] In this paper, models are built in MATLAB to test existing techniques and a comparative analysis of reliability indicators of equipment of different generations is carried out. The results of the study confirm that modern reliability calculation methods are superior to traditional approaches, providing higher rates of average time to failure and the probability of failure-free operation. The data obtained can be used to develop new standards and techniques, as well as for educational purposes. Keywords – reliability, telecommunication equipment, mathematical models, redundancy groups, reliability indicators, MATLAB.
