MATHEMATICAL MODEL OF CREATION OF THE RESERVE OF MONEY
A. V. Ganicheva
The relevance of the study is due to the need for rational management of funds, as an organization (enterprise), and various communities, individual entrepreneurs, family budget and individual. The article developed a new method for assessing the optimal management of cash reserves. For continuous and discrete cases, the mathematical models based on the device of the linear differential and differential equations are constructed. The change of reserve as a function of time is shown. Options of assessment of parameters are offered under accurate and indistinct conditions. The conditions for optimal management of reserve funds, as well as the solution of the problems of determining the time for this level of reserve and the initial value of the reserve at a given forecast level are formulated. The effective and inefficient management of funds under clear and unclear conditions is defined. The analysis of the dependence of reserve funds on the values of the parameters of the equations describing the process of reserve formation is carried out. The model of components of a reserve is considered. The problem of their optimum combination when maximizing a reserve is solved. The methods of integer programming are used in the solution. The materials of the article are of practical value, as they can be used in technology, Economics, ecology, military Affairs, social sphere.
Keywords: system, asset, the reserve funds, the parameters of the equation, optimal control reserve.

D. A. Nedosekin
The relevance of the research is based on the fact that the effectiveness of the main life activity systems is significantly determined by the development of high-tech technological systems that promote them (for example, equipment related to radiotelephone communication, equipment related to digital television, equipment for 3G, 4G-technologies). When considering a multidimensional interaction among them is education related to developing systems (ALS) (for example, include information telecommunication computer network). The structure of the decision-making system in the management of the SRS is given and the components of its mathematical support are described. The first group of procedures in the mathematical support of the JWP is related to the application of computational algorithms for determining the indicators reflected for the main and supporting systems in the standard methods, and the formation on their basis of the basic optimization problems for two subclasses of the SRS. The second group includes multi-module algorithmic procedures for choosing a rational control option, which includes, in addition to the module for the formation of a plurality of perspective options based on the results of randomized search, a preliminary module for the transformation of basic optimization problems, the final decision-making module using expert information. The structure of the index of readiness of regions to information society is given. The index is built on the basis of aggregation of values of indicators, and aggregation takes place at several levels, allowing to build ratings of regions in separate directions and factors of development of information society with varying degrees of detail. It is shown how the method of calculation of the index of readiness of the region to information society is used. The structural scheme of formation of optimization model of infocommunication technology (ICT) of the system is given.

THE MULTIPLE CHOICE IN THE MANAGEMENT OF DEVELOPING SYSTEMS
D. A. Nedosekin
In this paper we consider the problem of developing control related systems (CRS). They affect the way in which development is carried out adjacent to high technology systems. The article focused on the creation of algorithmic procedures, allowing for the management of CRS. The choice of a promising option in the optimization problem comes from the fact that ITT system is a progressive system in the structure of CRS. In procedure identified and described three modules. The block diagram of the algorithmic procedure of control selection boundary conditions for the development of a singly linked system and a block diagram of the algorithmic procedures for the management of reallocation of the financial resource of the base system. Procedure multialternative choice has the character of formalizing expert knowledge in the form of grades compatible promising directions of development of promotion system and can achieve effective interaction of all components connected developing system. The choice of option a valid boundary conditions for the development of information and telecommunication technologies (ITT) in the region is carried out by experts on the basis of a comparison of dominant strategies. Analyzed the sample statistics over a certain period of development component of the ITT in the period that gave opportunity to confirm the performance optimization.

THE MODULAR STRUCTURE OF THE SYSTEM OF DECISION-MAKING AND ITS IMPLEMENTATION ON THE BASIS OF MODELS OF MULTIALTERNATIVE OPTIMIZATION, DEVELOPING NETWORKS
D. A. Nedosekin
The research urgency is caused by the fact that for the present stage the efficiency of the development of the basic systems of life significantly depends on the development of supportive high-tech technological system (e.g., radio telephone communication equipment, digital television equipment, equipment for 3G, 4G technologies). In the multifaceted interaction between them is education related to developing systems (DS). In this regard, this article aims to identify the role of information and communication systems (ICS) (which, for example, is information-telecommunication computer network) as contributing to the structure of DS and assess the possibility of increasing the efficiency of its management on the basis of models and algorithms of multialternative aggregation. A leading approach to the study of this problem is the use of components of mathematical software that enables holistically consider optimization problems of the multialternative aggregation when managing classes of DS. The article presents the structure of the DS and the structure of the system of decision-making in the management of DS. The procedure of forming the multialternative optimization problems of aggregation of primary and enabling systems differ in the way the introduction of alternative variables through multi-dependency of criteria and constraints and allow us to start the algorithm performance find the maximum efficiency of the development of the coupled system when performing boundary conditions for the distribution of financial resource. The materials of the article are of practical value to professionals who are effective way to choose promising areas of ICS development.
