21. Academic performance rating in the automatic training system [№2 за 2013 год]
Authors: Shustova N.А. (komandor.99@mail.ru) - St. Petersburg Branch of the R&D Institute Centerprogramsystem (Senior Researcher), Ph.D;
Abstract: The article suggests to upgrade the interface of controlling part for the comfort of the instructor when creating and debugging tests in an automatic training system (ATS). In order to justify this suggestion there is an algorithm of obtain-ing the estimates for the test containing similar questions. It allows offering a unified table for test questions which can be used by programmers and teachers while preparing tests. A teacher also can enter data into the controlling part of ATS by copying their prearranged table in the controlling ATS database table. In order to correct the test it is proposed to use the results of the already collected data. This data are collected in a sepa-rate table which saves answers of the students who passed inspection.

Abstract: The article shows the importance of tactical simulators for of Navy officers training. It emphasizes the issue of actions appraisal of the students trained on tactical simulators. It also suggests the approach to the creation of such a total-parametric estimator. Each simulator task can be split into elementary steps to achieve an output. All performance parameters of preparedness of the students training on simulator are divided into two types. The first type is critical evaluation determin-ing the success or failure of the problem solution by students. The second type includes appraisal determining the overrange from norms or rules. Obtaining an integral estimation with these parameters is presented in the model of final appraisal gen-eration on the simulator based on the graph-analytical method.

23. Using domain-driven approach to advanced software systems design [№2 за 2013 год]
Authors: Karpov A.V. (KarpovAV@cps.tver.ru) - R&D Institute Centerprogramsystem (Branch Manager), Ph.D;
Abstract: Domain-driven design implies that software systems architecture development is based on domain model. When designing classic two-tiered advanced software systems, using domain-driven design often leads to functionality distribution throughout different programs. This functionality is connected with the same objects of one domain model. Adaptation of software system to changed conditions can require central user access to all the information about the do-main model objects. This central user access is provided when forming same information functional space of the system. It can be formed us-ing special interaction between program components of the system. There is a program-portal to use the information functional space for providing central user access to information about the general-system objects and processing functions. Proposed method allows using main advantages of service-oriented architecture in classic two-tiered advanced software systems.

24. Methods of solving the problem of access to service files under the conditions of mandatory access control [№2 за 2013 год]
Author: Efimov A.Yu. (efimovay@cps.tver.ru) - R&D Institute Centerprogramsystem (Head of Department);
Abstract: The article describes the problems of dealing with service data in a protected software environment with work-ing mandatory access control. The main causes of these problems are described. The article considers typical application op-erating scenarios that use service data when it is storing in files. It includes dealing with configuration files and history rec-ord. Conflicts between these scenarios with mandatory access control are identified. Access methods to service files resolving these conflicts are classified and described. These methods are based on the addition of Bell–LaPadula model and on con-trolled resources virtualization. Comparative analysis of these methods is performed in the context of usability and security. Selection criteria of suitable access method to service files for variety of application conditions are proposed, selection algo-rithm when using multiple criteria is described. An example of using the criteria and algorithm is given.

27. Bundled software for performance evaluation and tax policy optimization in federative systems in regional tax competitive environment [№2 за 2013 год]
Authors: (leonovana@mail.ru) - , Ph.D;
Abstract: Recently the tax relations issue is emphasized in Russian Federation. It is a relevant objective to research tax relations in order to optimize them. Furthermore it is necessary to carry out an accurate analysis of tax competition influence on attracting investment to regions using the decision theory methods in economic and social systems. In this regard the arti-cle considers a three-tier model of tax competition which consists of many investors, many regions and federal level of gov-ernance. This model includes agent costs on relocation in a chosen region and agent competition influence on investor activi-ty in given region. The bundled software has been developed to analyze this model. This software helps to obtain an optimized splitting standard of income tax rate between regional and federal part, transfer amount directed to regions by the federal level, balanced regional income tax rates and estate tax rates.

30. Methodology of creation of knowledge bases control systems for intelligent systems of decision support [№2 за 2013 год]
Authors: (bashlykovAA@mpei.ru) - , Ph.D;
Abstract: The methodology of creation of knowledge bases control systems for intelligent systems of decision support is considered. The architecture of knowledge bases control systems and all its components is defined. The offered architecture of control systems is considered as development of architecture of knowledge bases control systems. Questions of offered ar-chitecture orientation to existing formalism of knowledge models creation and to methods of automatic decisions search are stated. The descriptions are based on a formalism of semiotics knowledge model which is interpreted as a multimodel struc-ture of knowledge representation. The multimodel component belongs to semiotics model and includes: semantic networks, frames, formal models, production, computational models. There are inductive and deductive components of knowledge de-scribed by semiotics model. The inductive component includes means of knowledge description. These means help system users to define problems, describe multimodel knowledge structure of subject domain, logic of the problem solution of expe-ditious decision-making. The formalism of language of knowledge definition is one of these means. The main feature of a deductive component of semiotics model – representability of knowledge of management purpose achievement means in it. This knowledge looks like the ordered set of procedures, models and ways of their using (management on models) for the so-lution of tasks in multimodel knowledge structure. The formalism of knowledge manipulation language is taken as a basis of a deductive component, it is a mean of statement and finding solutions for solvable problems of decision support. There is a notion of concept of task resolvability in a knowledge model. The description of determination methods of task resolvability and planning of its decisions search processes is provided in semiotics knowledge model. Stages of finding solutions process-es planning are defined: finding the algorithm of problem solving; algorithm interpretation for receiving the result. Scopes of knowledge bases control systems are described.
Keywords: means of interpretation of models of knowledge in models of data, language of definition of knowledge, manipulation language knowledge, model of knowledge, control systems of knowledge bases
