Математическое моделирование социальных процессов
Currently, the tasks of ensuring the quality and stability of the provided IT services are extremely topical. In the operation of the composite applications, the problem of increasing the effectiveness of incident management is a complex technical problem, the solution of which requires the use of the simulation methods. In the work, the integration platform Ensemble of InterSystems Company was considered as a basis for designing integration solutions. Given the architectural features of the integration platforms, a mathematical model of the incident management process in the Ensemble integration platform is proposed. This mathematical model was used to develop algorithms for identifying and classifying incidents. The results of the work can be used in the design and development of incident management information systems, as well as in organizing the work of technical support services for IT companies
We consider the problem of manipulability of social choice rules in the impartial anonymous and neutral culture model (IANC) and provide a new theoretical study of the IANC model, which allows us to analytically derive the difference between the Nitzan-Kelly index in the Impartial Culture (IC) and IANC models. We show in which cases this difference is almost zero, and in which the Nitzan-Kelly index for IANC is the same as for IC. However, in some cases this difference is large enough to cause changes in the relative manipulability of social choice rules. We provide an example of such cases.
We present a general equilibrium model of Russian economy.

The report presents the results of study of the fictional text in terms of correlation of the local themes rendering as a whole its idea; the report introduces the notion of cumulative index of distribution of conceptual information. When analyzing the fictional text the method of mathematical modeling is used enabling to represent language features in particular mathematical models shown in tables. Using mathematics in linguistics aims to enhance reliability and accuracy of the methods of linguistic studies.
In this paper, using the theory of differential games developed the algorithm of constructing guaranteed control for nonlinear systems. Through the transition from the nonlinear model to model the linear form with parameters that depend on the state, will move from finding solutions to equations of Hamilton-Jacobi-Bellman equation to the Riccati equation. Moreover, the appointment of the "worst settings" will make the matrix not depend on the state that will allow you to solve Riccati equation and to synthesize the required control. The example of construction controls for non-linear mathematical model of the human immune system in the presence of the HIV. Built management controls the supply of antiretroviral drugs to maintain healthy cells of the human immune system at the required level to maximize and facilitate the life of the patient.
Built parametric suboptimal control of supply of drugs using the method of algorithmic design in the problem of stabilization of the cells of the immune system in patients with the HIV. A mathematical model describing the dynamics of HIV in the human body represents a nonlinear system of differential equations. In this paper uses the method of "extended linearization" (SDC, state dependent coefficient), allowing to switch from the nonlinear model to linear model, but with parameters depending on the state. Proposed a new method of algorithmic design for solving the resulting equations of Riccati.
This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
