  • Features of solving identification problems in transport technologies

    pg(s) 63-67

    The peculiarities of carrying out the basic methods of solving the problems of identification, which have become widespread in transport technologies, are considered. Three approaches were tested: a deterministic approach based on the method of selected points, a statistical approach that includes the least-squares method, and – an inductive approach – a method of group accounting of arguments. A number of experiments have been conducted, which is based on structural optimization of the model. In the process of analysis of the obtained models, a rational model of setting and solving identification problems in transport technologies of optimal complexity was obtained. This systematic flow diagram can be successfully applied to solve complex analytical tasks.

    pg(s) 59-62

    Automated production becomes a new reality of the industry, one of the important points in the construction of such production is a more accurate and quick design of technological processes for processing and assembly of parts. Analysis of computer-aided design systems shows the inadequacy of their capabilities to achieve this result. Significant improvement of CAD / CAM systems is required, for which it is necessary to establish close relationships between the part, tool, machine tool, technology, as well as digitize world experience and build an advanced algorithm that independently takes many different decisions, such as grouping part elements into operations and grouping transitions for their processing.

  • Data security model in cloud computing

    pg(s) 55-58

    In the last decade, cloud computing has become an extremely important business assistant that offers significantly lower costs than traditional computer-aided resource provision and greater adaptability to business changes. Thus, it helps them to achieve their business goals. The development of cloud computing poses significant risks, which serve as a partial barrier to their use by the businesses. Security and protection of information are considered to be one of the most critical points in the use of cloud computing. Compared to traditional solutions, cloud computing moves application software and databases to large data centers where information and service management are not always secure and reliable. As a result of this, the community and businesses have many concerns and questions about the security of data and applications in cloud infrastructures. In addition, concerns about data security and applications also arise due to the fact that both user data and applications are managed by the cloud provider. Clouds typically use a standardized data and application security architecture, while the demand for consumer and business services is steadily growing and becoming more diverse and with more sophisticated software design that leads to continuous upgrades to data security models in cloud computing. Due to the different methods of implementation in cloud computing service delivery models, the demand for a reasonable level of data protection is of utmost importance. The purpose of this publication is to propose a new information security model, which offers a solution for improving the use of sensitive data by introducing a three-factor authentication – an improvement of preventive control.

  • RULES FOR CHOOSING COMPONENTS OF A SINGLE DIGITAL PASSPORT FOR THE GENERATION OF CAD DESIGN SOLUTIONS

    pg(s) 14-15

    In previous articles, it was shown that for “Industry 4.0” production one of the important tasks is the collection, storage, analysis and processing of product data and related design and production procedures. This determines the implementation of PDM, ERP, MES and/ or EAM systems at enterprises and the construction of a metasystem based on them – a single digital passport. Its content allows to automate the generation of design decisions for timely management decisions, as well as to propose an approach to solve the problem of minimizing the impact of the human factor for the tasks of Industry 4.0. Therefore, the work presents the results of the development of the rules for choosing the components of a single digital passport for the generation of design solutions based on the principle of building a fuzzy Takagi-Sugeno-Kang network. The results obtained will allow to formulate a criterion for the similarity of the production object and the design and production procedure in the digital environment to the given requirements based on linear approximation methods.

    pg(s) 286-289

    The goal of this paper is to study algorithm for detection and classification of moving objects based on parameter estimates from their GPS signal shadow. The suggested algorithm uses satellite GPS signals to create radio barriers and to detect moving terrestrial targets. It can be examined as an algorithm for secondary application of the wireless technologies (SAWT). This technology is extremely modern and up-to-date and can find application in Industry 4.0 with regard to the reduction of the electromagnetic radiations. The GPS signals included shadow from several moving vehicles, processed in MATLAB environment in order to obtain the estimations of their parameters. In IBM SPSS Statistics, Scheffe test is used for classifying the moving objects. The results reveal that proposed signal processing of the GPS signal shadow combined with this statistical approach can be successfully applied in practice for object classification.
