1. A forecasting method for regional information networks functioning characteristics [№3 за 2009 год]
Authors: Шишаев М.Г., Датьев И.О., V.A. Putilov
Visitors: 9742
The article considers forecasting problems of the regional information network characteristics subject to socioeconomic factors of user environment dynamic. The medium-term forecasting method for network elements traffic characteristics is proposed. The method is based on system-dynamic modeling of network technical parameters and user environment socioeconomic factors.

2. Boundary conditions of local problem in subgrid method [№3 за 2009 год]

The filtration problem for a viscous compressible multiphase fluid mixture in a porous medium is considered. A correct spatial discretization using subgrid method is discussed. Algorithm of method parameters choice is described. A flow approximation error for homogeneous isotropic case is estimated.

3. Objectives tree method for assessment of efficiency of using information resources [№3 за 2009 год]
Authors: Stoyanova O.V., Зайцев О.В.

In this article the features of a problem of assessment of efficiency of using information resources by enterprises are considered. The problems which occur due to using traditional solution methods of this problem are found. In the article is proposed the approach which is different from the existing ones. It is based on using objectives tree method and allows increasing an adequacy and reliability of assessment of efficiency of using information resources.

4. Constructing of inductive models synthesis algorithms of difficult systems [№3 за 2009 год]
Author: Колос П.А.

The article is devoted to research of features of constructing of inductive algorithms of synthesis of models of the difficult systems on the basis of association of a few modeling algorithms, or separate their component, in new schemes, which have a new characteristics and provide more high level of adequacy of resulting models by comparison to algorithms which were fixed in their basis.

5. The generic algorithm for choosing the dominant signs for a neural network [№3 за 2009 год]
Author: Нигматуллина А.Н.

The problem of choosing the dominant signs for a neural network training selection forming is solved. For simplification the current problem the generic algorithm based approach is offered.

6. Applying models of cooperative decision making in intellectual systems [№3 за 2009 год]
Authors: Сикулер Д.В., Fomin V.V.
Visitors: 15093
The article is devoted to questions of usage of models of cooperative decision making in automated intellectual systems. Applying of such models to pattern recognition is being considered. Recognition software based on models of cooperative decision making is being described.

7. Analysis of the systems of treatment of information and control by means group fuzzy numbers [№3 за 2009 год]
Authors: Uskov A.A., Сургучева И.В., Горбунов А.М.
Visitors: 12868
Group algebraic operations over fuzzy numbers – operations at which application indistinct numbers derivate abelian groups on addition and multiplication operations are offered. It is shown that application of group algebraic operations at fuzzy modeling, in some cases, allows receiving results better in good agreement with practice, than those which are received with application of traditional fuzzy numbers.

8. The scheduling procedure as an integral-valued problem, for groups with one topical course [№3 за 2009 год]
Author: Шевелев С.Б.
Visitors: 11634
In work is brought original statement of the problem the timetable and is offered procedure of the timetable sheduling the educational institution as integer tasks without flows.

9. Estimation of logistical indicators in the conditions of the limited information [№3 за 2009 год]
Authors: Arefiev I.B., Klavdiev A.A.
Visitors: 9055
In article the method of an estimation of logistical indicators in the conditions of the limited information on parametres of functioning of transport system is proved.

10. Accelerated preference formalization algorithm for decision support [№3 за 2009 год]
Author: Портоне Д.С.
Visitors: 11278
In the article it is suggested to use the method of preference formalization for construction of rankings. This method is based on combination of traditional methods of vector criterion scalarization (a method of the weighed sum and a method of an ideal point) and the method of preferences, which was implemented in decision support system DSS/UTES.
