Usage of automated informational systems in the daily activities of a financial institution is the basis of its successful existence and development. The most common ways of automation in the financial sector based on own development or standard of automated banking systems (ABS) are no longer able to meet the increasing needs. That is why the use of successfully operating in other industries ERP systems becomes very attractive. For today, many researches has been done on the existing market of banking systems. There are also works describing the advantages of using ERP systems for automation of economic activities of the bank. Nevertheless, it is quite difficult to make a choice about strategy of automation. The aim of the study is to identify and assess the strengths and weaknesses of each of the ways of automation and their ability to withstand the opportunities and threats of environmental factors. The method of quantitative SWOT analysis based on expert assessments was used for this study. The quantitative SWOT analysis matrices had been obtained because the study allow decision-makers in the field of IT strategy to have a more balanced approach to the choice of the development path. Comparison of SWOT matrices for analysis of automation paths allows making a conclusion about the preference of using ERP system as a basic system in the bank.

The description of the mathematical model for the analysis of the state and forecasting the national security of the state is presented. The model is developed based on the system dynamics model. As model variables, the model uses national security indicators of various countries of the world (BRICS,UN). The model also uses external factors selected on the basis of correlation analysis and analysis of interrelated time series that affect the modeled variables. To illustrate the cause-effect relationships between the model variables, a digraph is constructed. The procedure for the formation of a mathematical forecast model for a specific country using structural coefficients is shown. The adequacy of the developed model was verified using retrospective data. The results of a computational experiment with the developed model for the Russian Federation are presented: the process of setting up the model is analyzed, the working areas of the model are highlighted, and the national security indicators of the Russian Federation are forecasted until 2020. For the accumulation, processing, analysis of statistical information necessary for the development of a forecast model and directly for forecasting the national security indicators of the state, a computer simulation system was developed. The basis of the computer simulation system is the «Program for modeling and forecasting the main indicators of national security of the Russian Federation», developed in GUIDE MatLab. The methodology of using the developed mathematical and software for the training of specialists in the field of national security on the basis of the educational resources of the RANEPA is presented. The situational training center, functioning on the basis of the Institute of Law and National Security of the RANEPA and the expertanalytical center of the RANEPA, is designed to conduct an express analysis of the socio-economic, political, demographic situation in the region / country; development of scenarios of socio-economic and political development of the country; modeling of critical situations arising in the real economic, social, political systems of the country.

A recognized direction of improving the efficiency of the use of organizational and technical systems is management automation, which provides increased efficiency and reasonableness of decisions made. A significant role in increasing the efficiency of any automated system is played by its software. First, this thesis refers to the application or special software. Development of application programs is fraught with certain difficulties, including those associated with the efficiency of user interfaces created in its process. The analysis carried out by the authors showed that there are a number of problems in this field, which are determined by the fact that it is located at the intersection of scientific disciplines: control theory, ergonomics, technical aesthetics, and psychology. The article analyzes the factors affecting the effectiveness of the development of user interfaces. Based on the analysis, proposals for solving problems based on the use of standardization, unification and prototyping tools were synthesized. Prototyping methods are divided into evolutionary and rapid. The analysis showed that for the conditions of developing application software of automated decision support systems, the latter approach provides the greatest efficiency, namely, the use of specialized prototyping systems. The article proposes to refine the regulatory documentation, which defines the development of automated control systems, to be implemented in the structure of the process of creating such systems, an obligatory stage of interface prototyping

Currently, work is underway on the development of promising portal tracklayer instead of the item on the supply tracklayer. Accordingly, there is a task to evaluate the application of newly developed technology on the manufacturing capabilities of military units RT when performing regular tasks. Stochastic modeling methods can be applied to solve this problem. This approach will allow to form a sample sufficient to assess the main probabilistic temporal characteristics of the system under study. To test this approach in solving this problem was developed a simulation model of the technological process for building the top structure of tracks. The model was created using simulation software. The results obtained in the course of carrying out numerical experiments using the developed «Simulation model structure the upper structure of railway tracks with the use of tractor tracklayers» allowed to justify the basic tactical and technical characteristics of the perspective of the tracklayers. These requirements were included in the tactical and technical task for the ROC to create a «Portal tracklayer» and «tractor tractor-dispenser». On the basis of the results obtained, during the model experiment, the main tactical and technical requirements for a promising tractor tracklayer machine were formulated.

The article discusses the risk management of investment, innovative and import substitution projects. Since the implementation of such projects requires investors and investments, innovative projects can sometimes be considered as a kind of investment projects, and import substitution projects as a kind of innovative ones. However, these projects have significant differences from each other in viewpoint of emerging risks. Moreover, a systemic effect may arise of a sharp increase in the complexity in the total project risk during the implementation of complex system projects. Therefore, the use of simulation with elements of artificial intelligence, including fuzzy logic and artificial life algorithms, is becoming relevant in the management of project risks. As a result, a new method is proposed for identifying the need to create hybrid fuzzy-logical simulation models or the absence of such a need based on identifying synergistic effects when analyzing the risk rubricator in a specific project. The analysis of the investment attractiveness of the Russia’s regions using the evolutionary-simulative methodology on the example of the Smolensk and Tambov regions. A new method is proposed for selecting innovation clusters and promoting innovative projects in the regions on the basis of integrated bacteria swarm-simulation modeling with detection of contours selected territories borders. A new economic and mathematical toolkit for managing the risk of import substitution has been created.

The clusterization problem on incomplete data is considered with its application to classification of the partly defined objects. The problem may arise in different practical areas including diagnosis making, forecasting, face recognition and so on. An original approach is outlined which involves a solution technique based on maximum independent set (maximum clique) definition in fuzzy graph (with evident interpretation of a cluster as some maximum clique in a fuzzy graph). An input partly defined object then gets to one of the cliques (clusters) with a decision undertaken specific to that clique. The entire approach subsequently uses a modal logical system, providing necessary formalization to find the maximum independent set (maximum clique) in fuzzy graph. This formalization is based on the transition from modal logic to Lukasewich multi-valued logics accordingly to Tarski theoretical results. The next step consists in transformation of the Lukasewich multi-valued logic to a classical boolean-valued system accordingly to suggested scheme. It is then shown how to formulate a pseudo-boolean optimization (pbo) problem and solve it by means of the suggested simple heuristic method which delivers a solution to a multipple kanpsack problem which we use instead of pbo. It is also noticed that there is a possibility to use different multi-valued Lukasewich logics to interpret a modal system in order to increase an accuracy of the solution. We give also a Python code realizing
a standard imputation of the missing data by means of using average values and show that this technique gives incorrect results while the suggested method provides a right solution. Together with acceptable computational complexity of the suggested approach this gives good reasons to recommend the entire rechnique to practical usage.
