A.M. Tsykunov Robust Control for Object with the Distributed Time Delay (pp. 2-8)
Abstract. The problem of robust control with reference model for object under external disturbances, with distributed time delay, and unknown parameters of mathematical model is solved. The algorithm of control that allows compensating the prior uncertainty of parameters and external bounded disturbances with required accuracy is derived. The numerical example and results of modeling are presented.
Keywords: robust control, state vector, disturbance, distributed time delay.
V.A. Kubyshkin, S.S. Postnov Investigation of Optimal Control Problem for Single and Double Integrators of Fractional Order Using the Method of Moments in Case When Admissible Control (pp. 9-17)
Abstract. The optimal control problem investigated for two dynamical systems of fractional order (single and double integrators) in case when admissible control search evaluated in space of functions which are p-integrable on the segment. The problem reduced to the problem of moments. For the latter problem conditions of statement and solvability are derived. In case of p = 2 an obvious solutions for optimal control problem are obtained. Dependencies of control norm and minimal transition time fr om order of fractional derivative are investigated. Comparative analysis of results for both of considered systems are evaluated.
Keywords: optimal control, moment problem, integrator, fractional derivative, fractional integral.
Yu.S. Legovich, D.Yu. Maximov Decision Choice Problem in Self-Organizing Control Systems (pp. 18-26)
Abstract. An approach to automatic reconfiguring of control systems with changing control goal is proposed. New logic operations that are used in determining of the system behavior variant priorities are defined. As an example the approach was used to reconfigure the system in the course of emergency first response.
Keywords: graph transformations, many-valued logic, mobile ad-hoc nets, net-centric control systems, self-organizing systems, decision making.

E.N. Shomova Probability Model of Influence of Scientific Research Funding on the Effectiveness of Innovative Project (pp. 27-32)
Abstract. The paper proposes and investigates the mathematical model of innovative project allowing to estimate the project effectiveness dependent on the volume of funding of the project scientific research phase. The conditions of existence of optimal funding volume of the phase are derived.
Keywords: innovative projects, optimization of financing, mathematical modeling, research and development, project effectiveness.
Abstract. Mathematical model of organizational behavior at the early stage of a crisis is proposed. Performance of small and middle sized organizations at this stage was analyzed and measured using the model.
Keywords: crisis, crisis management, weak signals, mathematical modeling, simulation, agent-based modeling.
L.Yu. Zhilyakova The Limit States Control in Absorbing Resource Networks (pp. 51-59)
Abstract. The properties of absorbing resource networks i.e. resource networks with sink vertices are studied. When there are several sinks in a network the lim it distribution of resource among them depends on its initial distribution among non-sink vertices. The two control problems in such networks are proposed. Sinks are treated as target vertices; vertices belonging to a transition (non-sink) component of a network are treated as control vertices.
Keywords: resource network, control, stochastic matrix, stocks, inhomogeneous Markov chain.
Control of Complex Technological Processes and Productions
G.G. Grebenyuk, A.A. Krygin, S.M. Nikishov Algorithmization of Technological Accessions to Electric Networks (pp. 60-70)
Abstract. Now decision-making process the connection of consumers to power networks is one of the most painful problems – both for consumers of electric energy, and power enterprises and organizations. The choice of a point of accession of a consumer to a power network has many versions of decision, each of which demands knowledge of technology of transfer and energy distribution in networks, characteristics of the network equipment and some other questions. The paper proposes the system approach, allowing to accelerate and automate decision-making process regarding technical possibility of technological connections of consumers' power receivers to distributive electric networks.
Keywords: electricity, technical accession, choice algorithms.
E.A. Larina, A.M. Sidorenko, E.N. Khobotov Scheduling Methods for Discrete Manufacturers (pp. 71-77)
Abstract. The scheduling problems for discrete manufacturers are discussed. Component parts are manufactured and production is assembled on such enterprises. The methods proposed for solving of the problems are based on aggregation idea. Computational experiments carried out with the proposed methods have confirmed their high performance.
Keywords: scheduling theory, control, planning, aggregation of information, assembling, engineering products, production program.
