- Novikov D. Discussion on the scientific journals' evaluation problem
The paper precedes the discussion on the scientific journals’ evaluation problem, induced by the paper of Oleg V. Fedorets “Collective expert examination of scientific journals: procedure of expert judgments aggregation and rating construction”, presented for the “Large-Scale Systems Control”. This article describes preconditions, goals and agenda of the discussion.
- Fedorets O. V. Collective expert examination of scientific journals: procedure of expert judgments aggregation and rating construction
The technique of gathering and aggregation of expert estimations for the expert rating construction for scientific journals in natural and technical sciences is des¬cribed. One of the distinctive features of scientific journal is its multidisciplinary character that demands estimations from the experts in various scientific fields. Another feature is that each expert estimates the set of journals; therefore a matrix of expert estimations turns out to be incomplete. Thus, an approach is offered to this problem that differs from the typical process of expert estimation where each expert estimates each object, and all experts have expertise in the same subject area.
- Abaev L. Ch. An approach to apply expert-based methods to estimate scientific journals
The analysis of the article «Collective expert examination of scientific journals: Procedure of expert judgments aggregation and rating construction» by O. V. Fedorets is carried out. Setting of scientific journals rating construction problem and aspects of carrying out the collective expertise are discussed. Various aggregation methods of rank experts’ estimations are considered.
- Mazalov V. V., Pechnikov A. A., Falko I. A. On constructing the scientific journals rating
The analysis of scientific journals rating construction based on the techniques of gathering and aggregation of expert estimations is carried out. Initial method is enhanced to allow making collective ranking.
- Mirkin B. G. On the "Collective expert examination of scientific journals: procedureof expert judgements aggregation and rating construction" article by O. Fedorets
It is shown that the method proposed in the paper “Collective expert examination of scientific journals: procedure of expert judgments aggregation and rating construction” needs more substantiation, although the fact of using a method for the problem is a welcome step. An alternative approach to rate Russian scientific journals is proposed: a taxonomy of the subject area should be developed so that the expert evaluations could proceed along the taxonomy branches.
- Orlov A. I. Methodological errors lead to incorrect administrative decisions
The reasons of methodological errors in O. V. Fedorets' article are discussed: inadequacy of procedure, evaluation criteria, experts, algorithms of calculations, terms. It is shown that basing management of scientific organizations on impact factor value leads to imitation of scientific activity. Problems of articles selection for peer reviews are considered.
- Sidelnikov Yu. V. Difficulties of scientific journals rating system construction
Difficulties are discussed that arise in formal construction of scientific journals rating system.
- Hovanov N. V. An article on russian scientific journals rating as an occasion to reflect on general principles of composite indices method application
An attempt to compare the technique of periodicals rating (proposed by O. V. Fedorets in his article) with composite indices method (CIM) by A. N. Krylov is made. It is demonstrated that deviation from the transparent structure of CIM implies uncertain judgements in the considered article.
- Chebotarev P. Yu. Journals evaluation and aggregation of incomplete point judgments
We discuss the method of data analysis proposed in the article “Collective expert examination of scientific journals: Procedure of expert judgments aggregation and rating construction” by O. V. Fedorets published in the same issue. An alternative approach to the aggregation of expert point judgments with non-uniform number of estimates is proposed. This approach involves the weighted mean of the judgments including a neutral prior judgment.
- Shakhnov I. F. About constructing the rating of Russian scientific journals
Some issues of construction of collective expert examination system are analyzed. Problems of development of concerted criteria system and verbal-number scales for estimation of alternatives by these criteria are described separately. Author underlines the importance of thorough elaboration of manifolds of qualitative and quantitative characters, according to which compared alternatives are assigned to different graduations on used verbal-number scales.
- Fedorets O. V. Aggregating results of expert stratification bypassing matrices of paired comparison: case of scientific journals rating
One of the distinctive features of a scientific journal is its multidisciplinary character that demands estimations from the experts in various scientific fields. Another feature is that each expert estimates the set of journals; therefore a matrix of expert estimations turns out to be incomplete. The routine is offered for absolute scale construction based on an expert estimations set; moving totals method is suggested for journals lexicographic ordering.
- Kochetkov S. A., Utkin V. A. Invariance in systems with non-ideal relay control
The invariance problem is considered for linear stationary systems with relay control inputs. The classical way of solving this problem consists in using sliding mode control algorithms. When actuators have imperfections (unmodeled dynamics, nonlinearities and so on), the chattering problem arises. In this article the invariance problem is considered for the system with non-ideal relay actuators. There are two approaches to solve the above problem. First method is based on parameterization of nonlinearities of relay by feedback gain coefficients. It is shown that chattering is suppressed completely when feedback coefficients tend to infinity. Another approach consists in using high frequency modulation signal to linearize switching characteristics of relays. Then dynamic compensator approach is utilized for linearized system. The simulation results show the efficiency of the proposed algorithms.
- Breer. V. V. Stochastic Models of Social Networks
Stochastic models of agents’ behavior in social networks are considered. Basing on these models the value of a network is evaluated for agents and for the control center – the principal. Social networks are classified on the basis of the factors influencing the behavior of agents in a social network. Equilibrium states of social networks are described along with their fluctuations. Various interpretations are studied in the limit when agents’ number grows to infinity; the influence of other micro characteristics of social networks is also investigated.
- Gubanov D. A., Novikov D. A., Chkhartishvili A. G. Models of influence in social networks
The article surveys the models of influence in social networks. The main classes of contemporary models of social networks are considered, and correspondence between the classes of models and reflected properties of modeled object is established.
- Latysheva M. A. Econometric modeling of social and economic development of Russian regions
The article is devoted to econometric modeling of level of social and economic development of 79 Russian Federation regions with application of models of the panel data. Basic general factors influencing the level of regional development of each considered subject are revealed. Subjects of the Russian Federation arranged by the potential of development. The most and the least safe regions were revealed. Quantitative influence of non-observable factors for each region which is reflected in the individual fixed effect is revealed.
- Mylnikov L. A., Alkdirou R. H. Method for investment projects lifecycle forecasting
The technique is considered for investment projects (a sort of innovation projects) lifecycle forecasting. The method to estimate project stages duration is suggested. Forecasting of investment project evolution helps to make timely management decisions and to reduce the losses from late project plans change.
- Routines for measuring parameters of management information in automated training systems
In educational sphere there is lack of quantifiable parameters of input information that can be used for decision making. The article studies a problem of structuring the input learning information. As a way of structuring it is offered to use graphs of concepts in the training documentation. For such graphs the routines are developed to measure the parameters like language, connectivity, structure, and the sequence of teaching.
