Документ Development the resources load variation forecasting method within cloud computing systems(Національний технічний університет "Харківський політехнічний інститут", 2020) Davydov, Viacheslav; Hrebeniuk, DarynaThe subject of research in the article is the models and methods of resources load forecasting in cloud computing systems using the mathematical apparatus of neural networks. The aim of the work is increasing the efficiency of computing systems resources usage (such as RAM, disk space, CPU, network) by developing methods of resources load forecasting. The article addresses the following tasks: development of an integrated approach to the problems of resources load forecasting within cloud computing systems, which includes thesyn thesis of a combining forecasting neural network; development of a forecasting neural network model based on Elmanneural network; development of a method for training a neural network based on an artificial immunity algorithm; evaluation of the effectiveness of the developed method. To solve the set tasks, the approaches and methods of artificial neural and immune systems were used, as well as methods of theoretical research, which are based on the scientific provisions of the theory of artificial inte lligence, statistic, functional and systemic analyzes. The following resultswere obtained: on the basis of the analysis of resources load forecasting methods in cloud computing systems, the main results of the methods were revealed, the advantages and disadvantages were demonstrated. On the basis of the research resultsanalysis, the necessity of improving analytical methods for forecasting the load has been proved. The method of computing resources load forecasting in cloud computing systems has been improved, which makes it possible to obtain more accurate assessment results and prevent overloads in cloud computing systems. The results obtained are confirmed by the experiments carried out using the means of the infrastructure of private infrastructure services. Conclusions: improved the resources load forecasting method based on the mathematical apparatus of artificial neural networks to improve the efficiency of their usage.Документ Analysis and comparative researches of methods for improving the software(Національний технічний університет "Харківський політехнічний інститут", 2020) Mozhaiev, Mykhailo; Davydov, Viacheslav; Liqiang, ZhangThe results analysis of main methods for identifying software vulnerabilities presents in the article. The results of authors’ research, synthesizing and regulating knowledge about systems for detecting software vulnerabilities, are presented. The software analysis methods used during certification tests are considered. It is shown that the methods and techniques existing for software security analysis use do not ensure the result accuracy under fuzzy input data conditions. This drawback is aggravated by strict requirements for the test scenarios implementation speed. This is largely due to the fact that experts, in order to a decision make, have to conflicting information large amounts analyzed. Consequently, it is necessary to develop a system for identifying vulnerabilities, the main task of which will be to the conflicting information amount minimize used by an expert when making a decision. The most promising direction the existing identifying vulnerabilities systems efficiency increasing is seen in reducing the burden on an expert by methods for identifying vulnerabilities and implementinga decision support system improving. This will significantly reduce the time spent on a decision making on software security, and, as a result, will the software security testing procedure accessible to a developer’s wide range make more.
