The software market and software manufacturing companies pricing strategies features are considered. А model describing the software producers and users interaction dynamics in the market assuming existence of pirated copies and external network effect is developed. The model may be used by software manufacturers as a tool of establishing the optimal pricing policy.

The article deals with the Russian economy rapid indicators statistical analysis and their behavior forecast based on fractal analysis approach. Five sets of indicators were considered which comprise aggregates, finance, prices, social sector and major industrial goods production. It is shown that the length of six or seven years features the analyzed indicators average cycle. Indicators projections given are based on the Hurst index calculations.

Foreign property management information systems features are considered. The advantages of these systems as compared with those of national information systems are discussed. Holistic approaches to building national information systems for real estate management which are not inferior to foreign analogues functionally are considered.

The article deals with current tasks of increasing the laboratory of radiation control automation level in the Lead Research Institute of Chemical Technology. The information system developed by the authors can significantly reduce the time needed to process the laboratory output data as well as the number of human errors.

The unified model describing a multilevel hierarchical structure of the government procurement monitoring is proposed. Based on this model the information and analytical framework of automated monitoring system using data warehouse technology and focusing on multivariate data analysis is developed.

This paper describes the purpose and benefits of 3D computer simulators, tools and features of their creation by means of virtual reality. Examples of the software simulator systems developed with the participation of the author present the features of their design. The practical importance of the use of 3D simulators in a wide range of industrial and education is shown.

An approach to drawings (sketches) searching based on a multilevel recognition and logical analysis is presented. The approach incorporates construction and comparison of objects patterns fuzzy attribute graphs and relies on the methods and tools of structural pattern recognition, fuzzy graphs, automatic reading of drawings and 3D models as well as exploring beam graph in the recognition process. Examples are given.

The article concerns the cross-platform programming technologies such as Java, Qt, GTK+. Their advantages and disadvantages analyzed. The technique of gradual learning using cross-platform approach is presented. The main points of moving from structured programming to object-oriented programming using GTK+ library are described.

The research deals with the development of methodology that helps to rate the results of search engine optimization. The results are defined by two types of search queries: according to the field of search (institutions of high education) and according to the name of an institution. In the work the sites of higher education institutions in Samara region are analyzed.

The issues of elaborating an efficient management system for University computerizing are discussed. Introducing additional mechanisms and models is proposed as an extension of well known information technology service- oriented approaches which provides the information problems set organizing and increases the final effects.

We describe design decisions adopted in our software implementation of decoder for a class of algebraic geometry codes. The solutions develop a methodology of generic programming and show some metaprogramming techniques which are valuable when solving similar problems from the field of error-correcting codes or more generally computational algebraic geometry. We also emphasize features of C++11 which are to improve support for generic programming in C++ language.

A method for investment processes analysis based on system approach is discussed. We analyze the dynamics of mutual investor and investment object influences. A decision-making supporting tool is composed of collaborative simulation and analytical models which in conjunction with application methods and techniques form the virtual modeling workbench. To illustrate the method an investment process associated with the municipal land use is considered.

Finite resources distribution mechanisms in a hierarchical control system are considered. The generalized model of system elements behavior consisting of two parts is suggested. The first model incorporates the concept of the fuzzy compromise game allowing performers to build the general resources distribution strategy using negotiations. The second model aims to harmonizing the interests of the center and performers on the basis of Nash balanced situations.

New methods for graph-analytical and algebraic description of administrative procedures are considered. The administrative procedures being analyzed provide public and municipal services in electronic form within the framework of «Electronic Russia» federal program. A method for systems formal description in terms of «unit», «function» and «object» is presented.

A method for estimating reserves reducing the resource consumption of goods and services which requires minimal resources is suggested. It is shown that the simulation may provide obtaining both statistical characteristics and the overhead distribution of each resource-allocation process. It is proposed to estimate reserves to reduce resource consumption of goods and services on the magnitude of the coefficient of variation, the value of right-sided asymmetry and the median of the empirical distribution of the resource costs.

The paper deals with Internet users’ communication. The main issues concerning social networks members and emerging communication threats are identified. Statistics on the growing number of Internet and social networks users is given. Steps to create software that allows users of social networks to prevent hackers’ access to their personal information are proposed. The advantages and disadvantages of implemented and proposed tools for preventing personal data leakage are noted. The conclusions about the study results implementation are made.

An enterprise management structure is modeled using graph theory approach. The management graph and the information graph are considered. An algorithm for constructing the optimal organization management structure is presented.
