21. The choice of decision-making criterions in the organizational and technical systems using information situations [№4 за 2013 год]
Authors: Zavgorodniy V.N. (zavgor@list.ru) - Military Institute of Continuing Professional Education of the VUNTS Navy "Naval Academy", Ph.D;
Abstract: The article considers the class of competing organizational and technical systems, their operation is based on extensive using of technical means and is in interaction with the environment. Controlled object interacts with the environment when fulfill the set tasks. This environment is interpreted in as an "enemy" and "nature". Uncertainty of knowing factors, conditions and laws of the interaction of the controlled object (subject) with the environment for command and control part (the decision maker) is generalized as a set of informative situations. Fragmentation of informative situations into classes depends on the uncertainty degree of information available for a decision maker when making decision. The article proposes an approach to the choice of mathematical criteria to estimate the effectiveness of competing organizational and technical systems which is based on the classification of informative situations. Such approach may be useful when developing decision support systems.

Abstract: The paper is devoted to application of the first-order logic in assumption-based truth maintenance systems (ATMS), performing a function of the reasoning support system. The formal ATMS description and the basic ATMS algorithm are stated briefly. Main shortages of the proposition-based basic ATMS algorithm are shown. Three different ways (ground atoms, valid predicates, unions of ground atoms related to the predicate) of expansion for ATMS application areas to the first-order logic are presented. Strong and weak sides of used methods are illustrated by examples. Necessary adaptations of the basic algorithm to use new possibilities are viewed. Possibility of various applications of considered methods are studied. In conclusion, main weak and strong sides of using the predicates or propositions in truth maintenance systems are summarized.

Abstract: Heuristic biologically inspired stochastic algorithms of real-parameter multiextremal functions optimization are called “swarm algorithms” and based on an imitation of a collective behavior of different kind of animals. They have demonstrated their effectiveness in many tests and are regularly used in practice. The main problem in these algorithms’ application is the necessity of many parameters fine tuning that predetermines performance effectiveness. Moreover, it is impossible to know in advance which algorithm is better fitted to the problem in hand. This article suggests an approach that simplifies making a decision of the fittest algorithm choice. The approach is based on a competition and cooperation of biologically inspired algorithms when they compete for a common resource and at the same time cooperate sharing useful information. The suggested cooperative approach is described in the article, performance comparison results on a representative set of test functions are presented and results of the approach application in weight coefficients adjustment for artificial neural networks based classifiers are given.

Abstract: The approach to provide cloud service for parallel computation in Matlab is proposed. The distinctive feature of the approach is providing not only a parallel Matlab cluster, but also a virtual personal workspace with Matlab GUI as a cloud service. The users of the cloud service have the ability to execute jobs on the Matlab cluster from the Matlab GUI. In addition, Matlab GUI can be used to analyze results of the computation. An architecture of the “Parallel Matlab” cloud service is described. The suggested architecture is implemented at the supercomputer center of the Institute of Mathematics and Mechanics UrB RAS using the Computational cloud platform of UrB RAS and supercomputer “URAN”. User workspaces are provided based on the virtual machines from Computational cloud platform of UrB RAS, which have Matlab GUI and Parallel Computing Toolbox installed. Matlab Distributed Computing Server is running on the supercomputer “URAN”. Integration of the virtual user workspaces with the cluster is done with the help of the SLURM resource manager. “Parallel Matlab” cloud service provides the integrated solution for parallel computation in the popular Matlab environment. Users do not have to install and configure parallel Matlab by themselves, the cloud service is ready to use and requires only a Web-browser. The installation and support of parallel Matlab is done by qualified cloud-platform administrators.

27. Data protection in self-organizing information system without using special facilities [№4 за 2013 год]
Authors: Drozhdin V.V. (drozhdin@yandex.ru) - Penza State University, Ph.D; (rzinchenko@yandex.ru) - , Ph.D;
Abstract: The safe access in self-organizing information system is described. The current state of information security and data protection is shown. To increase a level of safety of self-organizing information system three components are offered: interaction of information system with system of hierarchically connected users, interaction of users with the system via visibility areas, regular users' authentication based on their behavior. Interaction of information system with the system of hierarchically connected users united in a network structure, on the one hand, simplifies system creation and provides control of subordinated users’ activity by higher users. On the other hand, it gives an opportunity to the system to gain the help of higher users in case of a difficult or uncertain situation with the specific user. Using the areas visibility mechanism for all users allows to form the user representation of data domain easily and to delegate powers of higher users to the subordinated users, and the self-organizing information system will provide the correct functioning and the effective data processing according to conceptual data domain model. Regular users' authentication in self-organizing information system based on their behavior will allow to identify each user more precisely and to confer confidential powers more correctly. Thus, the offered approach combines naturally both program (automatic) and organizational means of information system security.

Abstract: The problem of designing control systems using soft computing is described with 3 degrees of freedom manipulator as an example. The article investigates a general methodology of robust knowledge base design using special intelligent toolkit (Knowledgebase Optimizator on soft computing technology). Variations of organization coordinated control are proposed: single knowledge base containing information about manipulator’s three links, and a divided control method (independent knowledge bases for particular links control). The efficiency of constructed intelligent control systems using soft computing technology is described in comparison with control system using constant settings of regulator defined by genetic algorithm. Set of performance criteria taking into consideration for automatic control theory methods of transition estimations and tailored to concerned control object (3 degrees of freedom robot manipulator) is used to estimate control systems work. Estimate of control system work is performed by results of MatLab/Simulink simulation and experiment series on practical control object.

Abstract: The article considers a market as an open socio-economic system involving a large number of interacting elements. Market research and analysis requires processing massive amounts of statistical data and information support to forecast marketing situations in order to select strategies and decision-making for their implementation based on formalized knowledge. At the same time, known methods based on using analytical expressions and games theory, describe the state of the elements statistically excluding changes in their behavior and interaction. The dynamics of the system behavior under conditions of uncertainty, risk, illegible or incomplete information is mostly unpredictable. That is why to make effective management decisions it is appropriate to use the agent-oriented approach to the description and simulation of the system elements interaction. These elements alter the properties and behavior depending on the environment. One of the fundamental problems of multi-agent systems construction is the organization of agents’ interaction. If there are restrictions to use procedural approaches, declarative languages are preferred for interaction of agents. The paper proposes an ontological domain model of agent interaction that defines a set of communicative acts. It also shows a model of "request" act in the notation of colored Petri nets. The adaptability of the system of agents' behavior is achieved due to the classification of indicators of external and internal environment using neural networks and selecting the appropriate behavioral strategies.
