Due to the overall growth of automation and informatization in all spheres of human activity, systems based on local area networks are becoming more common. Such systems find their use in the fields that place increased demands on the reliability, such as nuclear energy, aviation, chemical manufacturing, etc. To ensure continuity of service, spare part sets (SPT) are being formed in the development phase. SPT cost can reach half the cost of the entire system. In that regard the developer must take SPT costs into account at the stage of selecting the type of organization of computer networks. The paper presents a comparative analysis of the financial costs on the formation of sets of spare parts with different types of service conditions.
This study (research grant No 14-05-0038) was supported by The National Research University–Higher School of Economics’ Academic Fund Program in 2014.
Features of the application of standards for evaluation (predict) the reliability of mechanical and electromechanical devices and systems are considered. The main characteristics of the models of operational failure rate of mechanical components and provides recommendations for their use are given. The use of software tools that implement the methods for calculating reliability, can cause significant difficulties with the reliability of initial data.
System ASONIKA-K-MF is a VJ-visual environment reliability electron modules designed to automate the activities and management of the reliability of electronic equipment on the stages of projection-tirovaniya, manufacture, operation and scraps-tion . The system is designed as a client-server application that allows Playback izvodimost calculations and ease of operation.  Despite the fact that the software, similar to the system ASONIKA-K-MF, has not yet been created either in Russia or abroad, constant updating of operating systems has led to the fact that the client part of the system ASONIKA-K-MF-mouth RELA in the sense that was not compatible with modern operating systems Windows Vista / 7/8. Therefore, there was a task processing times, the new version of the client side (interak-tive interface) system ASONIKA-K-MF under the operating systems Windows Vista / 7/8, using modern methods and programming tools.
The need for a variety of converters appears in the condition of the need to reduce the time of calculation of reliability of simple products, such as printed circuit assemblies. One source of data for calculating the reliability of the programs may be operating modes ESI map. According generated maps based on templates from WFD 319.01.09 might receive automated information on ESI applied as part of the test site that will speed up the process of assessing nadezhnostnogo performance of electronic equipment.
The monograph contents totaled the many years results of Scientific school «The Automated System for Ensuring of Reliability and Quality of Equipment - ASONIKA» National research University «Higher school of Economics» (scientific supervisor of the Scientific school - academician of RANS, doctor of technical sciences, professor YU. Kofanov) and long-term cooperation with the scientists of Kiev Institute of mathematical machines and systems problems of the Ukrainian National Sciences Academy (Deputy Director on science, doctor of technical sciences V.P. Strelnikov). The final structure of the monograph had been formed in the discussion of modern problems of reliability aerospace electronic equipment at the XVII International scientific-technical conference «Systemic problems of reliability, quality, mathematical modelling, information and infocommunication technologies in innovation projects». This conference was dedicated to the 20th anniversary of the HSE. The book outlines the basics of probability-physical approach to the study and the assessment of the reliability of onboard aerospace equipment. Presents the methods of estimation of reliability parameters of electronic components, as according to reference data and test or operating results in the presence or absence of failures. Developed the methods of calculation of reliability parameters of mechanical elements of aerospace equipment as well as research methods reliability of redundant and non-redundant, non-renewable and renewable systems on the basis of adequate two-parameter distributions of diffusion. Established the theory of planning reliability test with lightweight, durable, including accelerated testing with new methods of processing the testing results and reliability assessment. We propose new methods of evaluation and prediction of the aerospace equipment reliability to measure the determining parameters. Developed methodology of the statistical characteristics evaluation of the degradation process for the study of single samples of aerospace equipment using information about its representative minobject (minibranch, mineralizatsiya). All problems of reliability, which is solved in this book (mathematical modeling, calculation and experimental evaluation of the reliability of systems) result in the identification of the time until failure (or to failure) distribution. It is proved that when assessing the reliability of onboard aerospace equipment, most accurate results diffusion DN-distribution. On the basis of the law of distribution can be carried out the evaluation of all the necessary parameters of aerospace equipment reliability (mathematical expectations developments, gamma-interest developments, the probability of non-failure operating time for the specified time, the residual resource and others). The book provides a large number of examples and problems, proving the effectiveness and efficiency of the proposed methods. Material monograph mostly taught HSE in the various courses of lectures. The monograph is intended for a wide circle of specialists working in the field design, testing and operation of onboard aerospace equipment, as well as students and graduate students of the HSE in the execution of their coursework, independent scientific research, and the preparation of graduation theses and dissertations.

Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
