Improved Software System for Calculating the Reliability Indicators of Complex Technical Systems

The article analyses the literature sources, which investigate the existing methods and means of calculating reliability indicators of complex technical (in particular, software) systems. The reliability model of a modern complex technical system is often depicted in the form of a reliability block diagram (RBD), which may contain thousands of elements, each transitioning between different states (e.g., operational, failed, restored). This leads to a vast space of possible states in the corresponding Markov model.

RELIABILITY EVALUATION OF THE TRIPLED WIRED CHANNEL WITH DOUBLED PROTECTIVE REINFORCEMENT

Modern computer systems rely heavily on the exchange of information through various physical communication channels. The failure of a communication channel, particularly in systems responsible for critical facilities, can result in significant material and human losses. Therefore, ensuring the reliability of communication channels is a pressing issue. This paper is part of a series of publications dedicated to evaluating the reliability of communication channels.

Reliability evaluation of wired duplicated control channel with common and separate cable jackets

Aim. An approach for quantifying the reliability of the wired duplicated control channel with common and separate cable jackets is developed. Method. Reliability block diagrams and dynamic fault trees are used to formalize reliability. To describe the specifics of the damage processes to cores and cable jackets, logical conditions are formed in the failure tree. States and transition diagrams of the control channel are formed for carrying out stationary and dynamic analyzes.
