MULTISTAGE TWO PERSONS GAMES WITH MAKING DECISIONS ON EACH STEP WITH AGGREGATED INFORMATION ON A CHOICE OF THE "CAUTIOUS" SECOND PLAYER Vagif Aliev, Federal state educational establishment of the supreme vocational training «Financial academy at the Government of the Russian Federation», Moscow, Cand.Sc., assistant professor (Aliev_VS@mail.ru). Abstract: Multistage game of two persons with the fixed sequence of moves at the information on everyone to a course about usual to the moment of decision making of background of game and the aggregated information on a choice of the player 2 on it to a course. The player 1, having on each step this information, the first chooses the strategy on this step and informs its(her) to the second only on the next course. The player 2, receiving the information on a choice of the player 1, operates cautiously, i.e. a choice of strategy on this course aspires to increase of the payoff functions. The maximal guaranteed results and the appropriate optimum (epcilon-optimum) strategy of the first player on each step are found.

ALGEBRAIC SUFFICIENT STABILITY CONDITION FOR PERIODICAL TIME-VARIANT CONTROL SYSTEMS Leonid Chechurin, St.Petersburg State Polytechnical University, St.Petersburg, Cand.Sc., Dept. Head (cepreu4@gmail.com). Abstract: Algebraic sufficient stability condition for periodical time-variant control systems is given. The result is based on Kharitonov Theorem for interval systems and Bongiorno sufficient condition for time-variant system stability. The efficiency of the method is illustrated by an example.

PID CONTROLLERS' STABILITY DEGREE OPTIMIZATION Alexander M. Shubladze, Institute of Control Sciences of RAS, Moscow, Cand.Sc., professor (shub@ipu.rssi.ru). Vladimir E. Popad'ko, Gubkin Russian State University of Oil and Gas, Moscow, professor, dean (Moscow, Lenin's Ave, 65, (495) 930-92-25). Anna A. Yakusheva, student (yakusheva_a@mail.ru). Sergey I. Kuznecov, («SRITeplopribor», (495) 999-18-16). Synthesis of control systems by criterion of the maximum degree of stability for PID is considered. Solutions with optimal degree of stability had been obtained. These solutions enable us to find further prospects of computer based development of control systems.

ADAPTIVE-BASED METHODS FOR INFORMATION TRANSMISSION BY MEANS OF CHAOTIC SIGNAL SOURCE MODULATION Boris Andrievsky, Dr.Sc., Leading Research Fellow (bandri@yandex.ru). Alexander L. Fradkov, Dr.Sc., Head of the Lab (Institute for Problems of Mechanical Engineering of RAS, Saint Petersburg, 61, V.O. Bolshoy Av., (812) 321-47-66, fradkov@mail.ru) Abstract: Three methods for information transmission based on chaotic signal source modulation based on: implementation of adaptive observers, adaptive identification with the Implicit Adjustable Model, and frequency modulation with the adaptive demodulator are described. Application on the proposed methods for information transmission by means of modulation of chaotic Chua's generator is presented.

COMPUTER TECHNOLOGY OF PURPOSES, STRATEGIC DECICIONS AND OPERATIVE ACTIONS CORRECTION DURING DYNAMIC CONTROL. Eduard A. Trahtengerts, Institute of Control Sciences of RAS, Moscow, Doctor of Science, Professor, Honored Scientist of Russia, Chief Researcher (Moscow, Profsoyuznaya st., 65, (495) 334-88-40, E-mail: tracht@ipu.rssi.ru). Abstract: Control decisions are divided into three levels: operative, strategic and purposeful. Their interaction is shown. Computer-based methods of correction of purposes, strategic decisions and operative actions during dynamic control are considered.

COMPETITIVE EQUILIBRIUM IN THE FINANCIAL MARKET Mikhail Gorelov, Computer Center of RAS, Moscow, Cand.Sc., (griefer@ccas.ru). Abstract: A model of prices forming in the financial market under the circumstances of lack of coincidence of expectations of trade participants is suggested. The existence of prices which balance the demand and supply is proved. The method of numerical search of such prices is proposed. It is shown that the model permits aggregating with preserving of its structure.

STRUCTURAL-MACHINE MODEL OF CONFLICT SOLUTIONS IN ORGANIZATIONAL SYSTEMS Semen Yuditsky, Institute of Control Sciences of RAS, Moscow, Doctor of Science, professor (499) 783-2085, vladislavlev@rambler.ru). Abstract: This paper proposes finite automata approach to the identification and resolution of conflicts in organizational systems which synthesize "linguistic technique" of the game theory and its extensions and methods of finite automata theory. In terms of finite automata, we form sequences of all possible states (configurations) system of interacting agents, which reflects the state of the structure of relations between agents and structure of agents relations to external factors, in discrete points of time. This provides an opportunity to formulate a general picture of the conflict and examine possible scenarios for its resolution. In implementing the game, the agent (in response to a competitor action) gets the opportunity to choose his own actions to achieve his goals through the finite automata based model. The paper considers the automata based model that shows the dynamics of the binary relations between game agents.

EMPIRICAL TECHNIQUE OF DECREASE IN MARRIAGE CASTINGS Voronin Yury, Volgograd State Technical University, Volgograd, Cand.Sc. (voronin@vstu.ru). Kamaev Valery, Volgograd State Technical University, Volgograd, Doctor of Science, professor (cad@vstu.ru). Boyko Nikolay, Volgograd State Technical University, Volgograd, student (quakex@gmail.com). Abstract: The empirical technique of decrease in marriage castings from iron-carbon alloys is considered. It is shown that use of a tree of ordering of defects and tables of definition of pair communications of the reasons of occurrence of defects promotes substantial increase of quality of cast preparations in mechanical engineering.

ESTIMATION OF THE RELIABILITY OF COMPLEX PARALLEL FULLY REPAIRABLE SYSTEMS Elmira Y. Kalimulina, Moscow technical university of Communications and Informatics, postgraduate student (elmira-yu-k@mail.ru ). Abstract: The problem of estimation of complex repairable parallel systems with non-exponential distributed recovery time is considered in this paper. The state graph for such system is presented here. The formula for the probability of no-failure operation is derived here.
