Fedosovskii M.E. - Development of methodological provisions for the automated designing based upon the mathematical category theory methods. pp. 10-22


Abstract: This article is devoted to the the methods used in the theory of Сomputer-Assisted Design. Development of a theoretical framework of technologies of the automated designing is an important scientific problem. One of directions employed to solve this problem is its reduction to a single universal formalism used for describing a variety of technologies, which will be appropriate for the design of complex heterogeneous systems for integration and coordination of these technologies. The solution to this problem depends on the choice of the mathematical apparatus. In this article the author proposes creation of the computer-aided design methods using mathematical category theory. The author then discusses methods for the formation of a mathematical apparatus for CAD based on the mathematical category theory in order to establish mathematical models and the correlations between them at different levels of abstraction. It is shown that the formulation of regularities in the mapping from conceptual view the conceptual view of the subject objectives the basic reasons are: a consistent mathematical apparatus of formation models;  an uniform structure of the regularities of formation models; existence of the laws of cyclicality. Pattern display models of conceptual representation in the model conceptual representation of the subject is the identity in the application of functional abstractions for dynamic and static components during the process of formation (establishment) of the relations between them and the identity of the models on the same level of abstraction with the same view.
Kuznetsova O.A., Gatchin Yu.A. - Automation of evaluation of the reliability of the designed and manufactured avionics products pp. 16-23


Abstract: For companies involved in the design and manufacture of a wide class of avionics products (from removable functional modules to navigation systems) ensuring the reliability and quality of products in general are an integral part of the working process. Despite the wide range of software solutions offered, some questions of automation of work to ensure the reliability remain unsolved. One of the components proposed for Automation is the information support of decision-making on the development of measures to improve the reliability. The system is based on the results of analysis enhance reliability by efficiently developed earlier actions, that will determine the direction of the newly developed measures to address the causes of failures. To solve the problem the authors carried out an analysis of the information and analytical activities of the units involved in the design, manufacture and far warranty and post-warranty maintenance of avionics products. The developed model of information support is a database of necessary and sufficient for the timely execution of work on the reliability in the proper form in compliance with the requirements of standards. The implementation of the proposed automated information system of support based on the reliability of the avionics product design, and evaluation of statistical data on the results of the operation will reduce the turnaround time for the reliability and improve the quality of the designed and manufactured products.

Grishentsev A.Yu., Korobeinikov A.G., Dukel'skii K.V. - Use of the method of numerical estimation for the technical interoperability. pp. 23-38


Abstract: The object of study involves the method for assessing the quality of technical interoperability means in the open information systems in accordance with the model of interoperability under the GOST R 55062-2012. The author proposes a method for calculating the estimated characteristics of technical interoperability based upon the evaluation of detection and transformation of data formats by nodes of an open information system. As an example the article includes  practical assessments of technical interoperability based upon  the criteria for detecting and converting formats, and some software packages for processing graphic images. It is noted in the article that if there is need to observe the evolution of the interoperability of the information system, it is then necessary to preserve the methodological basis for the formation of the initial parameters. The proposed estimation method is based upon the laws of information theory and it is determined by a formal model allowing to calculate the particular and general information entropy characterizing the technical interoperability as the ability of the information system under investigation to detect data in various formats and the ability of the information system under investigation to produce correct data transformations in various formats. The main result of the research is the developed method of estimating technical interoperability that allows to make a numerical estimation of the properties of technical interoperability allowing for the format detection and transformation. The practical result of the study is that it enables the numerical evaluation of interoperability, allowing one to monitor the dynamics of interoperability of various systems under conditions of interaction with a continuously changing inter-system information space.
Lyachek Yu.T., Al'kadi L. - Methods of creating parametric models of the geometric object in the modern CAD pp. 42-51


Abstract: The research is focused on methods for creating parametric models of geometric objects used in modern CAD, which provide an effective modification of the descriptions of the objects of design. The authors select three approaches to creating parametric models: preliminary, parallel and subsequent parameterization. The paper describes the application of models of each type, its characteristics ad means by which they are formed. The authors note that preliminary or software models are used for the formation of the simple design of objects and drawings of design elements. Parallel methods of formation are the most common when creating graphic images of flat and three-dimensional objects of arbitrary configuration. Subsequent parameterization is used to generate parametric models of previously created design drawings. To create the latter type of models an automatic generation of basic key elements of the image grid is used. The elements adaptively change depending on the size designations assigned new values used in the original description of the drawing. As a method of study the authors use comparative analysis of different parameterization systems, allowing to identify the main approaches used in them in the formation of various types of parametric models of graphic objects. The novelty of the approach proposed by the authors of modern parametric classification systems is in the ordering of the various areas of parameterization as well as methods and means used to create a variety of parametric models depending on the time of its creation and the relation of building the corresponding image. Under this approach, it is easily to view and compare all kinds of CAD, regardless of the specific approaches and tools for creating geometric models used in these systems.
Sorokin O.L. - ADS of the thermal engineering networks with the use of additional capabilities regulated by the intellectual components. pp. 42-48


Abstract: There is currently a functional expansion within the ADS systems (automatic design systgems), allowing for the implementation of new capabilities. One of such solutions allows for the forecasting in the sphere of engineering networks, including thermal ones. The object of study is the Automatic Design System for the Engineering Networks ( ADS EN), which is based upon the intellectual components for the automatised systems. Intellectual components within the ADS are implemented via programming modules involving fuzzy logic, and they are orientated towards the use of the frame architecture databases. Functional capabilities are aimed at modeling the processes within the engineering networks, achievement of efficient energy consumption, detecting trouble zones, showing irrational arrangement of the heating units. These goals are key goals and they require primary attention, however while studying ADS EN, there turned out the need for inclusion of the screen forms achieving a number of secondary goals. These secondary features of the ADS EN include provision of the entire range of advise on the protective contour, forecasting based on situation modeling of the contour condition considering the external influences and passage of time, etc.
Pykhtin P.S., Kamaev V.A., Kryzhanovskii A.I., Niklyaev I.Yu., Pykhtin P.S. - Planning of the mobile robot trajectory using a gradient of a function of investigations of the configuration regions of space pp. 48-60


Abstract: The article proposes an algorithm for constructing the trajectory of motion of a mobile robot using quality assessment studies of various regions of space configuration (GIRRT). The described algorithm is based on the RRT algorithm and can significantly increase the effectiveness of the latter to meet the challenges in the search for ways of spaces containing a large number of narrow passages. The quality of research space configurations at a particular point in this paper refers to a numerical measure of the likelihood of building a successful trajectory connecting RRT tree and this configuration. A comparison of the proposed GIRRT algorithm and the classical RRT algorithm is given. A series of simulation way-finding experiments was held. While solving the task of finding ways in area with few obstacles, the GIRRT algorithm shows performance close to that of the RRT algorithm. In turn, when finding a way to the loosely coupled spaces (the space where there are areas for which the number of reachable configurations do not belong to the region itself, is small), the GIRRT algorithm demonstrates significantly better performance.

Kruchinin S.V. - Development and using of CAD in the field of telecommunications pp. 61-68


Abstract: The article is devoted to the principles of the development and application of computer-aided design (CAD) in the area of systems, networks and telecommunications devices. Particular attention is paid to the need for specialized computer-aided design, specifically designed for exact types of systems and telecommunication networks. At that time, conventional technology, with a large audience in the face of the whole community of Internet users, with the technological capacity of the equipment allows to direct all scientific and technical resources for the development of these technologies and software, the telecommunication architecture of networks require a separate research and development. The author proposes the use of CAD software for layout networks justifies this decision, tests methodology for the development of such CAD and draws a conclusions about the effectiveness of such a decision. In the study, the author uses the methods of mathematical modeling, theory of sets and graphs, methods of software design and system programming. In order to confirm the results of the study the author uses an experiment. Scientific novelty lies in the fact that the area of niche networks undeservedly ignored in the scientific literature, and not sufficiently represented in scientific publications, being the prerogative of engineering design. Used in the development of niche communications the technologies and methodologies do not receive scientific study and communicated to the scientific community. This article summarizes the experience of the development of CAD for designing niche telecommunications systems and the use of it, becoming a summing up the previous work of the author.
Mikhalkov V.A., Sokolov Yu.M. - Implementation of Modern CAD in the Circuit Engineering of Electronic Devices pp. 74-82


Abstract: Automated schematic design of analogous electronic devices is associated with certain difficulties created by the high degree of their parameters inhomogenuity. At the present time it is impossible to carry out a full automation of designing analogous microelectronic devices, i.e. their engineering without human participation, especially in the process of solving tasks of structural synthesis. However, tasks of structural and parametric synthesis can be successfully solved by the maximum use of the engineer's competence and conduction of a close dialog interaction between the engineer and computer. This is in many ways conditioned by a wide range of analytical programs installed in modern CAD of electronic equipment. In their article the authors provide a review of opportunities of the NI ELVIS system for experimental research of analogous electronic devices. They also view the joint application of the Multisim and NI ELVIS systems to the process of engineering analogous electronic devices. Combination of Multisim and NI ELVIS systems in the process of a course engineering of analogous electronic devices allow students to get the best idea of working conditions at today's engineering organizations and, in particular, to minimize the load of manual calculations. Students perform the following circuit engineering procedures: selection of the scheme for an analogous electronic device; 'quick look' calculation; modeling of the chosen scheme by using the Multisim software; experimental research of a device by using the NI ELVIS system.
