    Mylnikov L.A. Microeconomic Problems of Innovation Projects Management (pp. 2-11)

    Abstract. The paper provides an overview of main approaches to management of innovation projects as well as describes the tasks of innovation management, which can be solved on macroeconomic and microeconomic levels. The analysis of difficulties and challenges encountered in solving the problems of microeconomic management of innovative projects is carried out. Based on this analysis the conclusion on actuality of development of methodological approaches to system modelling of innovative project regardless of its specificity is made.

     Keywords: innovation project, management, decision-support system, algorithm, analysis, forecast, optimization.

    Analysis and Design of Control Systems

    Mironovsky L. A., Solovyeva T. N. On the Properties of Regular Dynamical Systems (pp. 12-19)

    Abstract. The conception of regular dynamical systems is introduced and the necessary and sufficient regularity conditions are defined. The Vyshnegradsky plane application to analysis of properties of third-order regular system is considered. The areas corresponding to different combinations of system cross-gramian eigenvalues signs are identified on this plane. The lines of equiconditionality of system matrix at balanced representation are mapped.

    Keywords: regular systems, balanced realization, Hankel singular values, conditionality, Vyshnegradsky diagram.

    Kochetkov S.A. Algorithms of Control and Identification for the Profilograph-Profilometer Under External Disturbances (pp. 20-29)

    Abstract. The devices with differential inductive sensors designed for surface geometric parameters estimation are considered in the paper. The control and identification algorithms are designed under the assumption that determinate disturbances exist on the input of the system. The accuracy of parameters estimation can be tuned by feedback coefficients. The efficiency of proposed algorithms is proved by simulation results.

    Keywords: differential inductive sensor, determinate disturbances, limit cycle, identificator of parameters, surface roughness.

    Bolodurina I.P., Ogurtsova T.A. Control of Price of Services Provided by Companies of Telecommunications Industry (pp. 30-35)

    Abstract. In the paper for the description of dynamics of behavior of user's base of companies of telecommunications industry the logistical model of Trays-Volterra with delay on time is used. The problem of identification of parameters of the model on the basis of real data of user's base and the tariff policy of cellular communication operators is considered. The problem of optimum control of behavior of the enterprises on the basis of L.S. Pontrjagin maximum principle for systems with constant delay is numerically solved.

    Keywords: dynamic model, optimum control, cellular communication, operator, tariff policy.

    Control in Social and Economic Systems

    Gorelik V.A., Zolotova T.V. Some Questions of Estimation of Investors’ Portfolios Correlation Moments (pp. 36-42)

    Abstract. The article is dedicated to the correlation moments calculation of the optimal portfolios which are the solutions of maximization problem of linear combination of mathematical expectation and dispersion. It is proved, that at the same investors information condition the optimal portfolios corresponding to the different risk coefficients are positively correlated. The conditions of negative portfolios correlation for the investors with different estimations of the financial instruments return are developed.

    Keywords: mathematical expectation, dispersion, correlation coefficient, risk coefficient.

    Chkhartishvili A.G. The Coordinated Information Management (pp. 43-48)

    Abstract. The model of the coordinated information management is proposed, when agents are informed on the fact of management realization by center but, nevertheless, trust center messages. Conditions at which such management exists are revealed, some its properties are proved.

    Keywords: uncoordinated information management,coordinated information management, Nash equilibrium.

    Shchepkin A.V. Increase of Efficiency of Mechanism of Stimulation by Means of Choice of Parameters of Employees’ Activity (pp. 49-55)

    Abstract. The paper is dedicated to questions of construction of parameters of activity of employees on the basis of which the distribution of limited fund of compensation is made as well as to the analysis of efficiency of distribution procedures.

    Keywords: mechanism of stimulation, distribution of limited fund of compensation, efficiency of distribution procedures.

    Control in Medical and Biological Systems

    Babushkina N.A. Control of Chemotherapy on Ferromagnetic Nanoparticles (pp. 56-63)

    Abstract. The paper presents the mathematical model of chemotherapy on ferromagnetic nanoparticles. The model describes the process of tumor cells death when the method of magnetic localization of the antitumoral preparation inside the tumor is applied. This method allows destroying the oxygenated tumor cells located near the blood vessels as well as hypoxic  tumor cells located on the tumor periphery. The method allows to increase the efficiency of chemotherapy to a considerable extent. One of the control parameters of this method is the intensity of the external electromagnetic field at the moment of medicine introduction. This intensity defines the efficient doze size and the period of desorption of the preparation on ferromagnetic nanoparticles inside the tumor.

    Keywords: mathematical model, chemotherapy, tumor cells, electromagnetic field intensity, effective doze size, preparation desorption.

    Moving Objects Control and Navigation

    Dobrovidov A.V., Kulida E.L., Rudko I.M. Control of Object Movement in Threat Environment (pp. 64-75)

    Abstract. The paper considers the problem of object route selection and velocity profile in a threat environment when some observers located in preset area try to detect it. In the paper the probability of an object undetection through whole route by any of the observers is taken as a criterion for object route selection. The discrete optimization method of this criterion based on the dynamic programming principle is proposed provided that the object movement time is restricted by known value.

    Keywords: object route selection, performance of object routing, probability of object undetection through whole route, dynamic programming.

    Andrienko A.Ya., Tropova E.I., Chadaev A.I. Optimization of Time Sequence Intervals of Quantization Pulsed System of Terminal Control (pp. 76-81)

    Abstract. The paper proposes to replace the initial system for execution of statistical optimization of time sequence intervals of quantization pulsed system of terminal control with statistically equivalent one: output coordinates of equivalent system under action of certain combination of disturbances coincide with instants of first two orders of coordinates of initial system. The local formulation of discrete analogue of maximum principle is generally applicable to the equivalent system.

    Keywords: optimization intervals of quantization , statistically equivalent system, maximum principle.
