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.

Statistical analysis of three new measures of relevance redundancy and complementarity

Discriminant analysis is part of statistical learning; its goal is to separate classes defined a priori on a population and involves predicting the class of given data points.  Discriminant analysis is applied in various fields such as pattern recognition, DNA microarray etc.  In recent years, the discrimination problem remains a challenging task that has received increasing attention, especially for high-dimensional data sets.  Indeed, in such a case, the feature selection is necessary, which implies the use of criteria of relevance, redundancy and complementarity of e

Criterion modelling of the process of redundancy of renewable energy sources power generation instability by electrochemical accumulators

The paper analyzes the methods and ways for the redundancy of renewable energy sources (RESs) instability in electric power systems (PS). It is shown that these can be maneuverable capacities, in particular, thermal and hydropower plants, accumulators, hydrogen technologies, biogas plants. It is substantiated that, for various reasons, for the RESs to be developed and their capacity to be increased in power systems, electrochemical accumulators and highly maneuverable capacities existing in the PS are the most prepared for implementation.

Reliability Evaluation of Wired Tripled Control Channel for Common, Separate, and Mixed Cable Jackets

Aim. To develop an approach for quantifying the reliability of the wired tripled control channel with common, mixed, and separate cable jackets. Method. Reliability is formalized using block diagrams and dynamic fault trees. Static and dynamic models have been developed to evaluate the reliability indicators of the wired control channel with triple redundancy. The basis for obtaining these models is the state and transitions diagram. Static models are formed using logical-probabilistic expressions.

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.

Method for structural optimization of avionics of unmanned aerial vehicle

This paper presents an approach for identifying the optimal configuration of avionic systems of the unmanned aerial vehicle (UAV) based on an additive multi-attribute utility function.  The function arguments are technical and economic indicators of avionics design quality that are specified in accordance with the UAV requirements.  The method is developed on an improved decision model that has a high degree of adequacy primarily by the increasing number of the utility attributes and using advanced reliability models of avionic systems.  These reliability models consider in addition to the

MODEL OF TECHNOLOGICAL RECOVERY OF COMMUNICATION EQUIPMENT DURING THE USE OF ITS INTEGRATED REDUNDANCY FOR REMOTED SUPPLY BASES

The communication system develops in the direction of improvement of communication quality indicators, causing the corresponding complication of products that is not conjugated with the improvement of their reliability. Despite the successes of the technical diagnostics, the correlation between the duration of defect localization and the elimination of the failure (for diagnostics it takes up to 80% of the average recovery time) is observed.
