A METHOD AND A TOOL FOR INFORMATION GATHERING IN ONLINE TRAINING PROCESS MANAGEMENT BASED ON AUTOMATED COMPLEX OPEN ENDED ASSIGNMENTS SCORING WITH THE USE OF ERROR BANK
V.A. Latypova, V.V. Martynov
It is possible to monitor training process using different statistic reports in learning management systems and massive open online course platforms. Online training process can be managed effectively by means of analytics applications. Analytics is based on gathered information. Problems can occur during information gathering if an online course contains complex open ended assignments, assignments which can’t be checked using tests. There are methods among the existing methods which allow to gather information effectively: situational assignment and special methods for specific domain. The methods allow to get reliable and complete information for management purposes. But the methods are not universal. Their usage is limited to open ended assignment type and domain. There is a need to develop a method for every specific task if situational assignment can’t be used and there is no special method. A universal information gathering method based on automated complex open ended assignments scoring with the use of error bank is suggested in the paper. A tool was developed and implemented in training process in Ufa state aviation technical university from 2013 till 2019. The usage of the method and the tool allowed to increase information gathering effectiveness in online training process management in complex open ended assignments implementation.
Keywords: online learning, training process management, complex open ended assignment, information gathering method, error bank.

The article describes a linear optimization model, which is an interpretation of the linear programming model of Kantorovich L. V. The accumulated potentials are considered as variables, a brief description of which is given in the paper. Additionally, models of forecasted and full potentials are given. The use of accumulated potentials opens up possibilities for modeling objects with long life cycles. This significantly expands the scope of the linear programming methodology to study the behavior of socio-economic systems in market conditions. The foregoing is illustrated in relation to an enterprise of the engineering field. In particular, a comparison was made of the results obtained from the initial data and the results obtained by recalculating the potentials. Features of the dynamics of accumulated potentials allow us to solve the problem of using optimization approaches in conditions of the high volatility of the external environment, in the conditions of emerging markets. Efficiency models and models of time norms are described, which play an auxiliary role in the formation of a linear programming model. In addition, indicators of the potential time norm and potential intensity of the equipment used in this model are formalized. The final model for calculating the production program written using potentials is presented. The model reflects the optimal use of resources and takes the form of direct and dual linear programming problem reformulated with the use of accumulated potentials. The model includes a description of the potentials of the objective function and equations reflecting the potentials of resource constraints.
Keywords: linear programming, accumulated potential, forecasted potential, dynamic model, sociophysical object.

Negative factors affecting information security of countries are described. Special attention is paid to the information-psychological effects highlighted in the Doctrine of information security of the Russian Federation. It is pointed to the expansion of the use of simulation methods for modeling information impacts on social groups and the corresponding information counteraction. The necessary definitions related to the use of the simulation approach proposed for the study of complex nonlinear systems to the modeling of information influences in social networks are given. The description of the system-dynamic model of information counteraction in the form of differential equations system is given. Simulation experiments were carried out with the model on the Anylogic software platform and analytical dependences of characteristic times reflecting the susceptibility of the population of the country’s settlements to influence through social networks, including mechanisms of negative influence, on the statistical characteristics of users were obtained. Typology of settlements of the Russian Federation on characteristics of information propagation in social networks of regions is carried out. It is concluded that the identified relationships can be used to predict manipulative information effects and planning information counteraction. In addition, it is emphasized that the simulation model allows, using statistically observed variables, to estimate parameters and variables characterizing the dynamics of information propagation in the population, which are statistically unobservable.

S.M. Lavlinskii, L.L. Yakovleva
The relevance of the study is determined by the lack of well-reasoned assessments of the level of the strategic goals achievement that were stated in the strategic development programs of Russia resource regions, taking into account the analysis of planned activities resourcing.In this regard, this article is aimed at substantiating a new method for assessing the feasibility of living standards target indicators in the development strategy of a subsidized resource region. For this, it is proposed to use a combination of the Stackelberg model and the regional forecasting model. The forecasting model is a model of socio-economic development of the resource region, adapted to the characteristics of Siberian territories. The planning model is a Stackelberg model that formally represents a two-level mathematical programming problem. This toolkit allows not only to compare various development strategies in terms of the dynamics of the living standards of the population, but also to formulate a program for developing the mineral resource base at the expense of the federal budget and ensuring the highest possible level of the region’s own income. The main principles of the methodology are illustrated by the example of the Transbaikal Territory, for which an assessment was made of the living standards target values attainability that were recorded in the Transbaikal Territory Development Strategy until 2030. The materials of the article are of practical value for management decision-makers for constitution and evaluation of regional development strategies.
Keywords: indicative planning, regional forecasting, Stackelberg model, bilevel mathematical programming problem, region development strategy, living standards.

The main problem in the development of algorithmic support for an automated control system for the technical operation of aircraft is the stochastic process of the probability of transitions of aircraft from one state to another. The article discusses an approach to solving the problem of optimizing the parameters of automation of the process of technical operation of aircraft, by achieving the maximum value of the indicator of functional efficiency in the conditions of limited resources (personnel of the engineering and aviation service and ground handling facilities). The analysis of the development of an automated control system for the technical operation of aircraft and their current status is considered. Aircraft planning methods are considered, optimization models by various criteria are shown. The positive and negative aspects of planning based on the queuing system are reflected, as well as the analysis of existing decision-making systems in the planning of work on aircraft. It is noted that existing systems do not solve the problem of distributing specialists to aircraft when servicing a group of aircraft. The task of optimizing the control system in conditions of a limited number of personnel with a minimum training time for a group of aircraft. An algorithm is proposed that implements the procedure for prioritizing the performance of work by engineering and aviation service specialists in the process of preparing a group of aircraft. On the basis of information on the number of personnel, the training time, each specialist forms a priority (turn) for the performance of work by specialists on aircraft. This algorithm is implemented using the Delphi programming language, and calculations and their approximations were performed using MS Excel. The advantage of the above algorithm is the possibility of its application, subject to a limited number of personnel involved in the preparation of aircraft.

PRACTICAL ASPECTS OF APPLICATION OF THEORY OF GAMES TO THE ASSESSMENT OF SYSTEM SECURITY
L.V. Stepanov, A.S. Koltsov, A.V. Parinov, D.V. Parinov, B.A. Soloviev
: The paper considers the practical application of the game-theoretic approach to the task of assessing the security of systems. One of the factors determining the life and activity of any system is its safety. The concept of security is applicable to organizational, economic, engineering, biological and any other types of systems. The security status of the system is determined by many external and internal factors. Among the internal factors include the vulnerabilities inherent in this system, and among the external ones there are many threats that could potentially affect this system. The circumstance of the confrontation between threats on the one hand, and vulnerabilities (measures to eliminate vulnerabilities) on the other, makes it reasonable to use game theory methods to assess the security of a system.The parameters of threats and vulnerabilities, along with quantitative ones, can have a qualitative description, which limits the possibility of using mathematical methods. For this reason, these parameters must be formalized in a numerical form. To solve this problem, it is proposed to use a pairwise comparison of linguistic constructions. The obtained formalized values can be used to construct the game matrix.A feature of the approach proposed in the work is the possibility of its implementation in the form of algorithmic and software that will automate the work of analysts responsible for the formation of tactics and strategies for ensuring the security of any institution or organization. This fact reflects the practical usefulness of the proposed methodology.
Keywords: security system, security threats, system vulnerabilities, measures to counter threats, linear programming, game theory.
OPTIMIZATION MODEL AND INTELLECTUAL SUPPORT ALGORITHM FOR MANAGEMENT THE RESOURCE MANAGEMENT DISTRIBUTION IN THE ORGANIZATIONAL SYSTEM
Y.E. Lvovich, B.A. Chernyshov, O.N. Choporov
The article discusses the sequence of actions for the formation of an optimization model and an algorithm for intellectual support of the process of rating management of the distribution of resource support in the organizational system. The structure of the rating management system is determined by a set of features that make it possible to establish a sequence of particular management tasks that form a single decision-making cycle.The optimization model forms extreme and boundary requirements when coordinating the interests of the system’s managing center and the administration of its facilities in the distribution of resource support, which is allocated to each area of activity, contributing to a change in performance indicators to improve the facility’s position in the rating. Combining formalized requirements leads to the block task of linear programming.The intellectual support algorithm is based on a game approach to solving the block problem of linear programming. To this end, a transition was made to the vector-matrix form for writing direct and dual linear programming problems and iteratively searching for the saddle point of the Langrazh function with preliminary separation of the coefficient matrix and the constraint vector into two parts.
Keywords: organizational system, rating management, optimization, intellectual support, linear block programming.
FORMATION OF AN INDIVIDUAL SCHEDULE FOR STUDYING THE MATERIALS OF THE DISCIPLINE IN AN ELECTRONIC ENVIRONMENT
IN A LIMITED TIME OF TRAINING
The article presents the methodology for personalizing the schedule in the electronic educational environment for studying educational materials in the framework of the academic discipline. To solve this problem, approaches to personalization of training used in e-learning are considered. The central aspect of the study was the ability to effectively use the time allotted for study, which is especially important when studying at the university, according to the general curriculum. Factors that require an individual training schedule have been identified. These include the various initial preparedness of the student, personal qualities, different approaches of students to the organization of their work. The relationship of these factors with the student’s pace was noted and a functional diagram of the process of adaptive management of student learning activities was developed. The proposed method involves a dynamic change in the requirements for the level of development of educational material, depending on the current achievements of the student. Studying the educational material even at a level lower than planned will give the student a holistic view of the subject area being studied. Analysis of the results of practical application of the method in an electronic educational course on the Moodle platform shows that students in the allotted time for training in General master the entire program of the discipline.
Keywords: e-learning, e-learning system, personalized learning, individual schedule, the level of mastering the educational material, academic discipline, activity of the trainee, knowledge, skills, concept, learner’s pace of work.
DEVELOPMENT OF A MATHEMATICAL MODEL OF THE PROCESS OF PROVIDING HIDDEN INFORMATION EXCHANGE IN RADIO SECURITY SYSTEMS AND A COMPUTATIONAL METHOD FOR ASSESSING THE STEALTH FOR THEM
To control large areas, radio security systems are currently being used that provide information collection from radio-distributed sensors distributed throughout the facility. When a person or a foreign object enters the sensor’s coverage area, the sensor detects the occurrence of an emergency and sends an alarm signal via radio channel to the system control panel. At the same time, it is known from the literature that radio security systems themselves are subject to destructive influences aimed at disrupting their performance. In this work, the author, based on the previously proposed mathematical model and generalization of the known literature, developed a mathematical model of the process of providing hidden information exchange in radio security systems, taking into account the destabilizing effects (for example, imposing false data or suppressing interference) on the transmitted signals in the communication channel. A computational method has also been developed for assessing the stealth of information exchange in radio security systems based on fuzzy logic, the use of which under conditions of poorly structured and difficult formalizability of the source data and also in the conditions of a complex of destructive influences, can potentially help to more adequately assess the stealth of radio security systems. The results can be used to study the stealth of known and promising radio security systems. It is also possible to use the results obtained to increase the stealth of known and promising radio security systems.
Keywords: mathematical model, computational method, stealth, radio channel, radio security systems.
