I.V. Chepkasov, I.S. Zamulin, V.S. Baidyshev
In this work, we carried out molecular dynamics modeling in the LAMMPS software package for obtaining metal nanoparticles (Cu, Au, Ni, Al) from the gas phase at various synthesis parameters, with a detailed study of the effect of temperature and cooling rate on the shape, size and morphology of nanoparticles. Based on the data obtained, an algorithm was developed, on the basis of which a software package was created to optimize the parameters of the synthesis of metal nanoparticles. To implement the algorithm, the C ++ programming language was chosen as the main one. The effective physical quantities, model parameters, fitting coefficients obtained in the course of molecular dynamics simulations are not included in the source code of the programs, but are implemented in the form of plug-in databases, which can later be supplemented with new sets of metals and their alloys or refined for those already presented. With the help of this software package, it will be possible to determine the required conditions for the synthesis plant (temperature regime, cooling time, composition and concentration of metal vapors) to obtain nanoparticles with specified parameters (type of particles, their size distribution, ratio of components in a particle).

P.A. Savenkov, P.S. Tregubov
The aim of this study is to develop mathematical and software for detecting abnormal user behavior based on an analysis of their behavioral biometric characteristics to create new ways to provide analytical data to the analyzing service with a description of why the identified actions are considered abnormal. The subject of the study is the machine learning methods used in UBA / UEBA (User Behavioral Analytics / User and Entity Behavioral Analytics), DLP (Data Leak Prevention), SIEM (Security information and event management) systems. Object of study – UBA / UEBA, DLP, SIEM systems. This article provides an overview of the applicability of machine learning methods in intelligent UEBA / DSS systems. One of the significant problems in intelligent UEBA / DSS systems is obtaining useful information from a large amount of unstructured, inconsistent data. The methods and algorithms of intelligent data processing and machine learning used in UEBA / DSS systems make it possible to solve data analysis problems of various kinds. The application of machine learning methods in the implementation of a mobile UEBA / DSS system is proposed. This will allow to achieve high quality data analysis and find complex dependencies in them. During the study, a list of the most significant factors submitted to the input of the analyzing methods was formed. The application of machine learning methods in UEBA / DSS systems will allow you to make informed management decisions and reduce the time to obtain useful information.
Keywords: big Data, data science, software, machine learning information system, UEBA, DSS.
METHOD OF VERBAL ANALYSIS OF SOLUTIONS FOR THE SOFTWARE SELECTION FOR CUSTOMER RELATIONSHIP MANAGEMENT
E.S. Egorova, N.A. Popova
The relevance of the article is due to the existing difficulty in making decisions in the process of choosing software products that automate business processes of enterprises, including customer relationship management. Therefore, for a diverse analysis of systems, it is proposed to use a two-stage methodology for a formalized assessment of the functionality of software and systems. At the first stage, the results of a multivariate analysis of customer relationship management software are presented. During the criteria-based assessment, the functional and instrumental characteristics necessary for products of this type were selected. The results of the analysis showed that using this approach it is quite difficult to make a decision on the choice of a product, since all systems have approximately the same sets of functional capabilities. At the second stage of the study, in the process of determining the optimal system, it is proposed to use the method of verbal analysis of solutions to find the best alternative. As a result of a formal analysis of systems using the developed software application, a potential leader was identified among the systems under consideration, however, further research involving an expert and comparing all pairs of systems according to their strengths and weaknesses made it possible to distinguish another alternative among customer relationship management systems. The method of verbal decision analysis based on the opinion of experts in the field of design allows you to choose the most effective tool in a specific industry area, and the developed software application allows you to optimize the work of analysts.
Keywords: verbal decision analysis method, software, customer relationship management, CRM system, formal analysis of a set of initial alternatives, scale of normalized ordered differences.
THE CALCULATE OF THE TIME COUNT SPENT ON A SELECTING OF SOFTWARE APPLICATION GUI ELEMENT
A.R. Familnov, V.S. Zarubin, A.N. Morozov
The article deals with the quality assessment of user interfaces (UI) of computer programs based on the proposed mathematical model. Most often, the quality indicator of a UI is understood as the total time of elementary operations (actions) of users on UI elements (UIE) spent on solving a specific task. UIE means such interface elements as input fields, icons, various types of lists, tables, etc. The elementary actions are understood as finding, achieving and managing UIE. Сalculating the time to perform user actions can be quite complicated. This is due to the fact that for the calculation it is necessary to know which screen form and which computer program the UIE belongs to, and also in the solution of which problem it participates and in what sequence. The article proposes a conceptual model of IDUs based on the ER diagram, which includes entities describing the UIs and the relationships between them. Analytical dependences are obtained for the calculation of one of the components of the quality index of computer programs, namely, the time the user spent finding interface elements placed on the monitor. It is shown that the entities included in the ER-diagram are indexed sequences. To navigate in the ER-diagram, functions are proposed that allow you to find an element of a set by its index in the task profile, and vice versa – to find the index of a given element of the set. The calculation of the time spent by the user in finding the interface elements on the monitor is performed using Hick’s law.

THE USE OF MULTIVARIATE ANALYSIS TO ASSESS THE FUNCTIONALITY OF THE PROJECT MANAGEMENT SYSTEMS
E.S. Egorova, N.A. Popova
The relevance of the article is due to the existing complexity in the selection of software products that can effectively manage projects in various fields of activity. Therefore, for a full-fledged, diverse analysis of the systems represented on the industry market, it has been proposed to use a two-step method of formalized evaluation of the functionality of software and systems. As a result of the first stage, the results of a multivariate analysis of the software of automated project management systems currently on the market are presented. In the course of the criterion assessment, the functional and instrumental characteristics required for products of this type were selected. For each indicator, it has been proposed to use weights and ranking maps. The results of the analysis showed that the most important indicators for evaluating the automated project management software are: integration mechanisms with third-party systems, the possibility of networked multi-user interaction, technology for organizing business management processes in project management systems. At the second stage of the research, it was proposed, using functional and instrumental characteristics, to rank software products based on the opinion of experts in the field of design. For this, the method of verbal analysis of decisions was used. Thus, the evaluation of software products has allowed to conclude that in the market there are universal software that has its own advantages and disadvantages, but is not suitable for use in highly specialized areas. However, the method of verbal analysis of decisions based on the opinions of experts in the field of design allows you to choose the most effective tool for project management in a specific industry area.
