DOI: 10.21777/2500-2112-2019-2-74-84
Keywords: technical system, dynamic loading, resistance, reliability, tests
Annotation: In many practical applications, it is not always possible to solve the problem of optimization of technical system characteristics under dynamic loading at a given degree of reliability, especially for the objective function of a large number of variables. When solving this problem for the created small series technical systems at the design stage, there are no data for a priori statistical analysis and, as a rule, it is not possible to determine the entire set of possible disturbing effects (destabilizing factors or loads) that can lead to abnormal situations. Obtaining approximate solutions makes it necessary to conduct additional tests of the technical system to clarify the limit values of the parameters, which is associated with significant costs. Therefore, improving the accuracy of determining the required values of the characteristics of the technical system at the design stage will reduce the number of tests. In this paper we propose a modified method of sthortest descent on the basis of its interface with the method of accelerated search. The proposed approach allows to reduce the number of iterations and, accordingly, the number of tests while maintaining the required accuracy of the technical system parameters and to increase the stability of the solution to the reliability management problem at the development stage.
Probabilistic analysis of characteristics recovery cycle of a complex technical system
Release: 2019-1 (26)
DOI: 10.21777/2500-2112-2019-1-64-74
Keywords: efficiency, recovery cycle, stochastic process, residual life, forecasting, operation management of complex technical system
Annotation: The problem of the efficiency of the recovery cycle management of a complex technical system is considered. In the process of operation of complex technical systems, failures of some elements occur, and the quality of the system as a whole deteriorates. At the same time, the nature of the costs of ensuring and restoring the quality of functioning of systems is antagonistic. For each specific system, it is necessary to study the relationship between the parameters of the recovery cycle and the indicators of the quality of its functioning in relation to the complex indicator of the economic efficiency of the system at all stages of its life cycle. The article deals with the evaluation and effectiveness of management of the recovery cycle of complex technical systems on the example of civil buildings. As it is known, in the housing sector, with constantly growing material expenditures for the technical operation of buildings, the quality level of their functioning changes very slightly. It is proposed to adapt and Supplement the modern efficiency management apparatus with the recovery cycle of complex technical systems, developed for high-tech sectors of the national economy for the operation of civil buildings, taking into account their features as non-productive systems with a very high social status. Priority additions, determining the effectiveness of management of the rehabilitation cycle of civil buildings, proposed to use indicators of frequency (repeatability) of adverse situations in users of buildings and a set of socially significant costs to ensure the quality of the functioning of the building for a long time. The proposed additions provide a theoretical basis for the applied methods of management of the recovery cycle of complex systems based on the probabilistic analysis of the existing methods of technical operation of buildings.
Modernization of engineering education as a condition of innovative development of modern russia
Release: 2019-3 (28)
DOI: 10.21777/2500-2112-2019-3-83-88
Keywords: innovative development, production, engineering and technical personnel, modernization, system of professional education, training, science, integration, content training
Annotation: The article is devoted to the analysis of the problems existing in the field of training of engineers and technicians in the country. Particular attention is paid to the lack of interaction between production and institutions of continuing education, the decline in the prestige of the engineer profession, the backlog of content and forms of training from the modern requirements for the personality of a highly qualified specialist, etc. The directions of development of engineering education and its transformation into innovative education by special organization of student’s work throughout the study at the University in complex practice - oriented teams, inclusion of students in active creative activity, ensuring their mass participation in research and engineering work, creation of oriented forms of education are considered. The result identifies and describes possible ways to improve engineering education, among which priority should be given to integration of engineering education with industry and science, development of technologies of personnel training using the best traditions of Russian engineering school and the global experience, increased social and financial status of engineering technical worker, and a teacher of the vocational education system etc.
Analysis of methods and models of situational management systems
Release: 2019-2 (27)
DOI: 10.21777/2500-2112-2019-2-85-91
Keywords: situational management, production process, fuzzy logic, non-stationary object, classification of situations
Annotation: Formalized representation of complex non-stationary production processes leads to exponential complication of mathematical methods and models and often the impossibility of solving them, including heuristic methods. The article analyzes mathematical methods and models of situational control systems of the production process. The features of their application for different types of production processes are considered: discrete, discrete – continuous, continuous. An integrative approach is proposed to construct a system-wide model, which combine continuous flow and discrete event flows. This approach makes it easier to formalize the knowledge of specialists in the subject area and use only one form of knowledge representation – flow diagrams. The use of system models based on integrative flowcharts allows to change the type of individual chart elements in the process of system reengineering without changing the topology of links that formalize expert knowledge about the subject area, which significantly reduces the labor costs of changing the model.
The base of the central movements and schools of zen buddhism
Release: 2019-1 (26)
DOI: 10.21777/2500-2112-2019-1-75-80
Keywords: Chan Buddhism, Zen Buddhism, school of Zen Buddhism, enlightenment, religion, koan, school of Chan Buddhism
Annotation: The problem of this study is relevant in modern conditions. This is evidenced by the frequent study of the questions asked. Also the relevance of this work is due, on the one hand, a considerable interest in the topic of Buddhist traditions in modern science, on the other hand, its lack of development. The article examines the stages of Buddhist religiosity as a cultural and historical phenomenon that characterizes the anthropological aspect. The factors influencing the study of philosophical and historical features of Buddhism, as well as the consideration of the structural components of the national culture of Buddhism on the example of traditional schools of Zen Buddhism are considered. Further attention to the issue of this problem will be considered in more depth, from the point of view of a reasonable solution of particular topical problems of the subject of this decision. To understand the development of these historical processes should be determined in the main directions of the Buddhist tradition, which we consider the example of the formation of Zen Buddhism. The ways of formation of the main schools of Zen Buddhism are determined, the analysis of their formation is carried out and the main tendencies of development of the school of Chan and Zen Buddhism in modern conditions are revealed. The object of the proposed study is to analyze the conditions of formation of schools of Zen Buddhism.
